Wheel Type IdentificationHub Piloted Disc Wheels

Hub Piloted disc wheels are designed to center on the hub at the center hole or bore of the wheel. The wheel center hole locates the wheel on pilots built into the hub. Hub piloted wheels are used with two piece flange nuts which contact the disc face around the bolt hole. Only one nut on each stud is used to fasten single or dual wheels to a vehicle. All stud and nut threads are right hand. Hub piloted wheels have straight through bolt holes with no ball seat, which provides a visual way of identifying them

Stud Piloted Disc Wheels

Stud piloted disc wheels are designed to be centered by the nuts on the studs. The seating action of the ball seat nuts in the ball seat bolt holes centers the wheels. Stud piloted dual wheels require inner and outer cap nuts. Fas-teners with left-hand threads are used on the left side of the vehicle and those with right hand threads are used on the right side of the vehicle.

Wheel Bearing Adjustment Procedures

PREFACEThe following Recommended Practice is subject to the Disclaimer at the front of TMC’s Recommended Main-tenance Practices Manual. Users are urged to read the Disclaimer before considering adoption of any portion of this Recommended Practice.

OBJECTIVEThe goal of this Recommended Procedure is to achieve a verifiable wheel bearing end play of 0.001” to 0.005” (0.025 mm to 0.�27 mm).

SCOPEThe following service procedures apply to steer, drive, and trailer axle assemblies using conventional double nut or single nut systems. Follow these service proce-dures carefully to prevent premature wheel end compo-nent failure and increase seal and bearing life.

ABS (anti-lock braking systems) and traction control systems with wheel end sensing require precise bearing adjustment to function properly.

This Recommended Practice details proper service pro-cedures for D-type, bendable-type, and dowel-typespindle nut washers.

NOTE: For single nut self-locking systems, consult manufacturers’ instructions.

If you have a system that differs from what is indicated in this procedure, consult the vehicle manufacturer’s rec-ommended procedure.

WARNING: Never work under a unit supported by only a jack. Always support the vehicle with stands. Block the wheels and make sure the unit will not roll before releasing brakes.

CAUTION: If your axle is equipped with spoke wheels and the rim clamps have been disassembled to remove the tire and rim assembly, the tire and rim assembly must be reinstalled and the rim clamps properly torqued BEFORE adjusting the wheel bear-ings. Failure to do thismay result in improper wheel bearing adjustment.

REFERENCESTMC RP 622,Wheel Seal and Bearing Removal, Instal-lation and Maintenance.

PROCEDURESStep 1: Lubricate the bearing with clean axle lubricantof the same type used in the axle sump or hubassembly.

IMPORTANT(a) In oil bath systems that rely on differential fill to

provide lubricant to the wheel seals, do not pack bearings with grease before installation. Grease will temporarily restrict or prevent the proper cir-culation of axle lubricant and may contribute to wheel seal failure.

(b) Never use an impact wrench to adjust wheel bearings.

Step 2: After the wheel hub and bearings are assembled

TMC RP 6�8 © 2003 – TMC/ATA – Reprinted with Permission

77

on the spindle or axle tube, torque the inner (adjusting) nut to 200 lbf• ft (27� N•m) while rotating the wheel hub assembly. Refer to Table 1 at the end of this Recom-mended Practice.

Step 3: Back off the inner (adjusting) nut one full turn. Rotate the wheel.

Step 4: Re-torque the inner (adjusting) nut to 50 lbf• ft (68 N•m) while rotating the wheel hub assembly. Refer to Table 1 at the end of this Recommended Practice.

Step 5: Back off the inner (adjusting) nut. Refer to Table � at the end of this Recommended Practice for the prop-er back-off amount.

Step 6: Install the locking washer.

If dowel pin and washer (or washer tang and nut flat) are not aligned, remove the washer, turn it over and re-install. If required, loosen the inner (adjusting) nut just enough for alignment.

IMPORTANTNever tighten the inner (adjusting) nut for alignment at this point of the procedure. This may pre-load the bearing and cause premature failure.

Step 7: Install and torque the outer (jam) nut. Refer to Table 1 at the end of this Recommended Practice for proper torque values.

NOTE: This adjustment allows the wheel to rotate freely with 0.001” to 0.005” (0.025 mm to 0.0127 mm) end play.

Step 8: Verify end play with a dial indicator. Wheel end play is the free movement of the tire and wheel assem-bly along the spindle axis.

(a) Make sure the brake drum-to-hub fasteners are tight-ened to the manufacturers’ specifications.

(b) Attach a dial indicator with its magnetic base to the hub or brake drum.

(c) Adjust the dial indicator so that its plunger or pointer is against the end of the spindle with its line of action ap-proximately parallel to the axis of the spindle. See Fig. 1.

(d) Grasp the wheel assembly at the 3 o’clock and 9 o’clock positions. Push the wheel assembly in and out while oscillating it to seat the bearings. Read bearing end play as the total indicator movement.

NOTE: If end play is not within specification, read-justment is required.

Step 9: RE-ADJUSTMENT PROCEDURE

Excessive End PlayIf end play is too loose, remove the outer (jam) nut and pull the washer away from the inner (adjusting) nut, but not off the spindle. Tighten the inner (adjusting) nut to the next alignment hole of the washer. Reassemble the washer and re-torque the outer (jam) nut. Refer to Table 1 for torque values. Verify end play with a dial indicator.

Insufficient End PlayIf end play is not present, remove the outer (jam) nut and pull the washer away from the inner (adjusting) nut, but not off the spindle. Loosen the inner (adjusting) nut to the next alignment hole of the washer. Reassemble the washer and re-torque the outer (jam) nut. Refer to Table 1 for torque values. Verify end play with a dial indicator.

FINE TUNING THE ADJUSTMENTIf, after performing the readjustment procedures, end



78

play is 0.004” - 0.005” (0.�02 mm - 0.�27 mm) range, re-peat the appropriate procedures, removing the washer from the spindle, tighten or loosen the inner adjusting nut the equivalent of �/2 of an alignment hole of the washer, or reversing the alignment washer, and reinstalling it onto the spindle. Reassemble and re-torque the outer (jam) nut. Refer to Table 1 for torque values. Verify end play with a dial indicator.

NOTE: Bendable-type washer lock only: Secure nuts by bending one wheel nut washer tang over the in-ner and outer nut. Bend the tangs over the closest flap perpendicular to the tang. See Fig. 2.

CAUTION: Before operating the unit, the wheel hub

cavities and bearings must be lubricated to prevent failure. For final wheel end assembly refer to TMC RP 622.


WHEEL BEARING ADJUSTMENT PROCEDURESTEP �: Lubricate the wheel bearing with clean axle lubricant of the same type used in the axle sump or hub assembly.Note: Never use an impact wrench when tightening or loosening lug nuts or bolts during the procedure.

Wheel Seal and Bearing Removal, Installation & Maintenance


PURPOSE AND SCOPEThis Recommended Practice defines practices and pro-cedures to perform a wheel seal replacement that meets fleet requirements. This Recommended Practice sets forth procedures and standards for storage, handling, and installation of wheel seals and wheel bearings for heavy-duty vehicles.

INTRODUCTIONA wheel seal is comprised of as many as six components, each manufactured to within a tolerance of a few thou-sandths of an inch. These components are assembled in precision fixtures, packed, and delivered ready for use. A wheel seal is a precision component, expected to do a demanding job. How it performs depends largely on the conditions of the seven mating wheel end components and the care taken during installation.

WHEEL SEAL AND BEARING HANDLING ANDSTORAGEMany wheel seal failures can be traced to improper han-dling and/or storage of the seals or bearings prior to use. Seals and bearings must be handled with care.

�. Wheel seals should be kept away from electric motors, welding equipment, and all other sourc-es of ozone. Fluorescent light and direct sunlight are also destructive to wheel seals.

2. Store wheel seals and wheel bearings in a clean, dry place. They should not be exposed to ex-tremes of either dryness or dampness.

3. Wheel seals and wheel bearings should be kept in their original factory packaging until ready for installation. Never store wheel seals or wheel bearings unprotected in open bins, where they may be exposed to airborne contaminants.

4. Never hang wheel seals and bearings on hooks or nails. Never tag wheel seals or bearings with inventory tags by looping wire through the seal or bearing. These practices will damage the deli-cate seal lip, the rubber inside diameter (I.D.) or outside diameter (O.D.) of the seal, or precision machined bearing surfaces.

Keep wheel seals and bearings clean—Never lay wheel

seals and bearings on a dirty surface and wash your hands prior to handling them. Avoid dropping oil seals and bearings. This will cause internal damage which may not be visibly apparent, but may be sufficient to im-pair their efficiency. Seals or bearings which have been dropped should be replaced.

NOTE: Never rotate an unlubricated wheel bearing or spin it with an air gun.

WHEEL SEAL AND BEARING REMOVAL ANDDISASSEMBLYWheel Seal Removal—A pry-bar is recommended for removal of the seal from the hub bore. A spindlemountwheel seal can be driven off the spindle by striking the ring from the back side or prying off with a crow’s foot bar. If a flat wear sleeve is on the spindle, remove it by striking the sleeve face with the round end of a ball peen hammer, expanding it for easy removal. Never use a sharp tool or chisel to remove the sleeve, because this will damage the shoulder area of the spindle. Discard the used wheel seal and use a new one during reas-sembly.

Bearing Cup Removal: Ferrous Hubs—Removal of bearings and cups should be done with extreme care so that hub bores, bearings, spindles, and housings are not damaged. Follow the hub manufacturer’s procedures for removing the bearing cups. This can best be done by using a bearing puller or press. When pullers or presses are not available for cup removal, a soft steel bar may be used. Do not use hardened drifts, center punches, or brass bars. They may chip and cause damage or per-sonal injury.

Bearing Cup Removal: Aluminum Hubs—Removal of bearings and cups should be done with extreme care so that hub bores, bearings, spindles, and housings are not damaged. Follow the hub manufacturer’s procedures for removing the bearing cups. To remove the cups, heat the hub to 250 - 300° F (�20 - �50°C) in an oven. Do not exceed 300° F (�50°C). Higher temperatures may weak-en the hub material. Do not use acetylene torches or other welding equipment to heat the hub because local-ized high temperatures may result, weakening the hub. Allow enough time in the oven for the hub to reach a uni-form temperature. Hub temperatures can be measured by using a temperature probe such as a thermocouple or temperature sensitive wax markers which are widely available from temperature measuring equipment sup-pliers. Use the appropriate safety equipment when han-dling the hot hub to avoid burns. Next, place the heated hub in a press and press the cup out.

Cleaning Wheel Bearings—A bearing which has been

TMC RP 622 © 2003 – TMC/ATA – Reprinted with Permission

80

removed from a vehicle should first be cleaned with a petroleum distillate solvent. The solvent itself must be clean and filtered. Steam or water should never be used. They will rust bearings in a very short time.

After a bearing has been cleaned with solvent, it should be dried using a compressed air gun and blowing air through the bearing from one end of the roller to the oth-er. When air is used to dry a bearing, make sure there is no water in the air line and do not spin the bearing at any time with compressed air.

To ensure against unnecessary wear, all parts and as-semblies coming in contact with, or operating together

with, the bearing should be thoroughly cleaned with sol-vent, dipped in clean axle lubricant, and placed in pro-tective oil paper. If oil paper is not available, use a clean, dry shop towel.

PREPARING WHEEL SEALS AND BEARINGSFOR INSTALLATIONRefer to Fig. 1, for a diagram of a properly installed wheel seal and related components. The correct instal-lation of oil seals ensures maximum sealing efficiency and service life. There are four items which affect proper installation and oil seal performance: first, the hub bore and the spindle must be prepared to receive the seal; second, the seal must be prepared for installation; third,



81

the seal must be properly installed using tools designed for the purpose; and fourth, bearing end play must be properly adjusted.

The contact surfaces where the new seal will be in-stalled must be free from rust, scale, old sealant, nicks, burrs, and any roughness that would prevent a good seal. Clean contact surfaces with scrapers that are soft-er than the hub material to avoid scratching the hub or seal bore. When cleaning aluminum hubs, use non-me-tallic scrapers to prevent damage.

Inspecting and Preparing the Hub Bore—1. Inspect the bore into which the seal fits. Check

for nicks or gouges that could cause leakage. Sharp corners at the bore entrance can score the seal O.D. when it is pressed in and can cause oil leakage.

2. Remove any rust, scale, old sealant, and rough-nesswith a scraper. Then use fine emery or cro-cus cloth for a final cleaning. If there are any deep grooves, fill them in with a hardening gas-ket material. Redress the filled area with emery or crocus cloth.

3. Sharp edges on the bore entrance should be chamfered or rounded off with a scraper, then carefully smoothed with an abrasive cloth.

4. Thoroughly clean and dry the entire area. Make certain it is completely free of dirt, grit, chips, or other abrasives which will score or mar the seal’s outer surface and cause leakage. 5. Be sure all oil is removed from the lubricant cavity. Wipe the cavity clean using a clean, dry cloth.

6. In the event of wheel bearing failure or severe contamination (by sand, grit, water, metal etc.), the lubricant cavity should be flushed of the old lubricant and refilled with clean lubricant.

Inspecting and Preparing the Spindle— �. Thoroughly clean the spindle with solvent and a

clean, dry shop rag, then examine the spindle for flaws.

2. Remove any rust, old sealant, and roughness with a scraper and use crocus cloth to polish the spindle area that contacts the sealing surface. Fill deep scratches or chisel marks with a hard-ening gasket material and redress the damaged area. Clean all threads and keyways thoroughly with a wire brush to avoid false bearing adjust-ment and to avoid introduction of contaminants into the lubricant cavity.

3. Sharp edges on the lead-in chamfer on the seal’s bearing shoulder should be rounded off with a file or oilstone.

4. Wipe the entire spindle surface with a clean, dry cloth, making certain the spindle is completely free of dirt, grit, chips, or other abrasives which could damage the seal’s inner surface and cause oil leakage. Clean all threads and keyways.

5. Apply a thin coat of non-hardening sealant to the axle shoulder when installing sealing systems which employ an axle ring or wear sleeve.

Bearing Inspection—A bearing which has been re-moved from a vehicle should be cleaned with solvent. Steam or water will rust bearings and should never be used.

Bearings that are rusted, flaked, pitted, or have dam-aged cages should be replaced. It is wise to replace all questionable bearings and always replace the cup and cone as a matched set. Never reassemble a tapered roller bearing in a damaged or worn housing or on dam-aged or worn spindles.

Housing spindles should not be remachined if the bear-ing journal is worn. Contact your OEM/axle supplier if wear is present. After the cleaned bearing has been in-spected and found to be satisfactory, it should be dipped in axle lubricant and wrapped in clean oil paper if not used immediately.

Replacement bearings should be stored in a clean, dry place and should not be removed from their cartons ntil ready for use. There is no need to remove the rust pre-ventative coating from new bearings upon installation.

After a new bearing has been removed from the carton and wrapper, it should be immediately installed on the vehicle. Never place bearings on a floor or a dirty work-bench, or in a dirty wash tank. Do not leave them ex-posed in open trays, pans, or cabinets where dirt, dust, and moisture can reach them.

Preparing the Seal for Installation—�. Carefully examine the new seal for any evidence

of damage or careless handling.

2. Some seals are lubricated before packaging to prevent rusting or oxidation during storage. Do not remove this factory lubrication. Other seals may require lubrication before installation. Fol-low the seal manufacturer’s recommendation. If lubrication is needed, use a light film of wheel



82

end oil.

Bearing Cup Installation: Ferrous Hubs—If a bear-ing cup has to be replaced, care should be taken not to create burrs or otherwise damage the cup or cup seats. The cup seats should be inspected for burrs or nicks and repaired to ensure bearings seat properly. If the hub bore is scored or damaged, the hub should be replaced. Proper drivers should be used to install cups to prevent bearing damage. The hub bore should provide a press fit.

Bearing Cup Installation: Aluminum Hubs—Clean and inspect the bearing bore and cup seat. Remove nicks, burrs, and foreign material. If the bore is scored or damaged, the hub should be replaced. The hub bore should provide a press fit.

To install bearing cups, heat the hub in an oven to 250 to 300° F (�20 to �50° C). Hub temperatures can be checked by using a temperature probe such as a ther-mocouple or temperature sensitive wax markers which are widely available from temperature measuring equip-ment suppliers. To ease assembly, the cup may also be chilled.

Coat the cup O.D. with a liquid graphite-based lubricant, such as Lubri-Kote, A �040 CR, or equivalent. Using a cup driver and applying hand pressure, seal the cup squarely against the shoulder. Lubricate both inner and outer cups with axle oil and install, mating new bearing cones with new cups.

WHEEL SEAL AND BEARING INSTALLATIONPROCEDURESAfter the bore, spindle, seal, wear ring (where applica-ble), and bearing have been examined and prepared,the wheel seal is ready for installation. Recommenda-tions on installation tools and procedures vary among different wheel seal manufacturers, so be sure to use only installation tools and procedures recommended and approved by the wheel seal manufacturer.

NOTE: All pre-lubrication must be done using the same oil that will be used in service unless the wheel seal is pre-lubed at the factory.

Hub Mounted Wheel Seal: Tool Installation—1. Place the hub assembly flat or at least at a 45°

angle for seal installation.

2. Select the correct tool handle, adapter plate, and bearing pilot for the seal being installed. Tool identification information is printed on most man-ufacturers’ packages or in catalogs. Prelube the


inner bearing cone with clean oil and place it in the hub. Place the oil seal on the tool with the air side facing the adapter plate or place the seal onto the hub bore and insert the tool assembly into the seal as recommended by the wheel seal manufacturer.

3. Hold the tool straight and drive the seal with firm hammer strokes until the seal is squarely seat-ed. Ensure that the inner bearing rotates freely. Lubricate the I.D. of oil seal with clean oil.

NOTE: If the seal uses a separate wear sleeve, in-stall it on the spindle as follows:

a. Place the wear sleeve on the spindle shoulder.b. Select the proper tool and drive the sleeve

home. Check that it is completely on the spindle and the edge is square with the shoulder within 0.005 inches.

Hub Mounted Wheel Seal: Hand Installation—�. Lightly lubricate the seal I.D. and O.D. evenly

with oil. Also apply a thin film of oil on the hub bore that is to receive the seal. Never install the seal without oil.

2. Hand press the seal evenly into the bore. A rubber mallet or other soft-faced tool, if recommended by the manufacturer, may be used to gently tap the seal into place. Apply an even driving force to avoid cocking the seal or damaging the flange surface. Be sure that the seal is evenly seated and bottomed in the bore.

Spindle Mounted Wheel Seal: Tool Installation—�. Place the seal on the spindle so that it has be-

gun to seat on the seal journal with the “oil side” marking facing the spindle end.

2. Select the correct installation tool supplied by the seal manufacturer. Do not install seals with-out the correct tools and/or adapters (where ap-plicable).

3. Place the correct driving tool in place and drive the seal until the tool bottoms out. Rotate the tool and repeat to ensure proper seal location.

4. Remove the driving tool and inspect the seal to ensure that it is square and bottomed out within 0.005” on the spindle shoulder. Do not proceed with further assembly until the seal is flush with the spindle shoulder.

5. Pre-lubricate the inner bearing and insert it onto the spindle. Fill the hub cavity with oil.


83


REASSEMBLY NOTE: Wheel bearing adjustment af-fects wheel seal and wheel bearing life. The first indica-tion of excessive wheel end play is wheel seal leakage.

�. The axle must be level. If tires are mounted on the hub, use a wheel dolly and align the hub as-sembly with the spindle and push into position. Care should be taken to avoid contacting the spindle end during the assembly process. Cau-tion must be exercised when installing the seal over keyways or threads.

2. With the wheel dolly in place, fill the hub cavity with clean oil. This step is mandatory for prop-er bearing and seal performance. Apply clean oil to the outer bearing and place it in the hub. In-spect the threads of the adjusting nuts and hand tighten prior to removing the wheel dolly.

3. All major seal, bearing, and axle manufacturers require a minimum of 0.00�” to a maximum of 0.005” end play for adequate seal and bearing performance. Performance improves as end play decreases to 0.00�”. Compliance with end play requirements are verified with a calibrated dial indicator on every wheel end.

Specific torquing procedures to achieve the end play tolerances are documented and available from the indi-vidual axle, bearing and seal suppliers.

NOTE: Never use an impact wrench to adjust wheel bearings.

4.a. For steering axles and trailer axles only— In-stall the hub cap using a new gasket and fill with clean oil to the proper level. Allow time for the lu-bricant to pass through the outer bearing before rechecking to verify the final oil level. Hub cap bolts should be torqued to �0 to �4 foot-pounds in a star pattern. Check the hub cap vent plug to make certain the vent hole is clean. Reinsert the plug.

4.b. For drive axles only—Reinstall the axle shaft using a new gasket or gasket material. Torque the nuts to the manufacturer’s specifications. If wheel hubs are equipped with oil fill/drain plugs, add a pint of oil to each wheel end.

For standard hubs, each side of the drive axle must be raised a minimum of 8 inches to move the lubricant into the opposite wheel end. Re-check the main sump for the proper oil level and top off the lubricant level if required.

Always check the axle breather to be sure it is operating properly and is completely free of dirt and debris.

LUBRICATIONCorrectly lubricate wheel seals and bearings in accor-dance with OEM recommendations. Improper lubricant level could cause severe wheel end damage. Do not mix lubricants.

Recommendations for Wheel End Lubrication



PURPOSE AND SCOPEThe purpose of this Recommended Practice is to offer equipment users recommendations and operational con-siderations for selecting lubricants for use in wheel end applications. This Recommended Practice applies to Class 3- 8 trucks, buses, tractors, and trailers designedfor on-highway applications. This Recommended Prac-tice applies to only “traditionally” equipped axles and hubs. This Recommended Practice defines “tradition-ally” equipped axles and hubs as wheel ends equipped with two single row, widespread, tapered roller bearing assemblies which are manually adjusted.

This Recommended Practice addresses two categories of wheel ends: driven and non-driven. Non-driven wheel ends include steer, dolly, trailer, pusher and tag axles.(See Figures 1 and 2). The lubricant used in the wheel ends can be either petroleum-based or synthetic-based oils or greases.

REFERENCEFor additional information on wheel bearing adjustment, installation and maintenance, refer to TMC:

• RP 6�8, Wheel Bearing Adjustment Proce-dures.

• RP 622, Wheel Seal and Bearing Removal, In-stallation, and Maintenance.

Other relevant TMC Recommended Practices include:• RP 624, Lubricant Fundamentals.• RP 709, Hubcap Standardization — Bolted- On

Type.

Fleet managers should also reference original equip-ment manufacturer (OEM) maintenance and service manuals as appropriate.

NON-DRIVEN AXLE LUBRICANTCONSIDERATIONSNon-driven wheel ends can be lubricated effectively with either oil or grease, depending on the fleet ap-plication. Both lubricating substances use oil as the lubricating medium. (Refer to RP 624, Lubricant Fun-damentals for details.)

A. Non-Driven Oil-Lubricated Wheel Ends

Inspection and PreparationClean and inspect the wheel end components includ-

ing

all bearings, hubcaps, hub and bearing cups, axle spin-dle, and fasteners, removing all contaminants and lu-bricant residue. Replace seal, hubcap gasket, and all questionable parts. For detailed procedures, refer to TMC RP 622.

Component LubricationPre-lubricate the inner and outer wheel bearing cones with clean lubricant of the same type used in the hub assembly.

! CAUTION : Failure to lubricate bearing correctly,and maintain proper lubrication, may result in bearing damage. For additional information refer to TMC RP 6�8 and RP 622.

! CAUTION :In oil bath systems, do not pack bear-ings with grease before installation. Grease will tempo-rarily restrict or prevent the proper circulation of lubricant and may contribute to wheel seal failure.

TMC RP 63�A © 2003 – TMC/ATA – Reprinted with Permission

Hub Fill Procedures: Oil Install the wheel seals as documented in RP 622. Ap-ply lubricant to the bearing journals and bearing cones. Use the same lubricant that will be used to lubricate the system. This will help inhibit fretting corrosion and make assembly easier. Use lifting equipment to align the hub assembly with the spindle taking care not to damage the seal and spindle threads. While the hub is supported/suspended, fill the hub cavity with clean oil and push the hub into position, or push the hub into position and then fill the hub cavity.

Install the outer bearing, and adjusting nut systems. Ad-just wheel bearings using TMC RP 6�8 or OEM Mainte-nance Manual. Verify end play (0.00�” to 0.005”) with a dial indicator.

Hubcap Considerations: OilSelect the proper vented, bolt-on or threaded hubcap for the application and follow hubcap suppliers’ instructionsfor proper attachment to the wheel hub. Fill wheel end assembly through the fill port with the same oil. Allow time for the oil to seep through the outer bearing and fill the hub cavity. Continue to add oil until the oil reaches the oil fill line as indicated on the hubcap. (See Figure 3.)

NOTE: For hubcaps with side fill plugs, do not allow the oil to go past the centerline or vent hole.

! CAUTION : Overfilling or under filling a wheel hub with lubricant may result in premature component fail-ure.

Install center fill or side fill plug. Torque side fill plug to hubcap manufacturer’s specifications. Clean-up any

over spills that would give the appearance of a leaking hubcap.

B. Non-Driven Grease-Lubricated Wheel Ends

NOTE: Semi-fluid greases are NLGI 000 and 00. NLGI 0 is a soft grease. All three grades listed above are treated as semi-fluid greases in this RP. Hard greases are de-fined as NLGI 1, 2, and 3 consistencies in this RP.

Inspection and PreparationClean and inspect the wheel end components includ-ing all bearings, hubcaps, hub and bearing cups, axle spindle, and fasteners, removing all contaminants and lubricant residue. Replace seal, hubcap gasket, and all questionable parts. For detailed procedures, refer to TMC RP 622.

NOTE: If retrofitting an oil or grease system with a semi-fluid grease, be sure to note the need for special clean-ing instructions, fill procedures and equipment (i.e., vented hubcap).

Component LubricationPack the inner and outer wheel bearing cones full with grease. Work the grease into the bearing in the direction of the arrow shown in Figure 4 by machine or hand such that the grease goes under the bearing cage toward the cone rib and roller ends.

For corrosion prevention, place a light film of grease on all metal components, including the hubcap. Wipe off the excess grease. Install the wheel seals as described in TMC RP 622.

! CAUTION :Failure to lubricate bearing correctlyand maintain proper lubrication may result in bearingdamage. For detailed procedures, refer to TMC RP6�8 and RP 622.

! WARNING : If grease packing is done by hand, appropriate protection — such as gloves and clothing — should be worn to minimize skin contact with the grease.

86

! CAUTION :Overfilling or under filling a wheel hub with lubricant may result in premature component failure.

Hub Fill Procedures: Semi-fluid GreaseIf tires are not mounted, install the hub on the spindle. Take care to not damage the seal. Use lifting equipment to align the hub assembly with the spindle taking care to not damage the seal and spindle threads and push the hub assembly into position. With the hub supported, be-fore installing the outer bearing cone, begin filling from the bottom of the hub cavity. Top-off by placing the pump nozzle above the spindle, and continue pumping grease into the hub cavity. (See Figure 5.)

The grease fill amount should be to a 3 o’clock and 9 o’clock level. This represents 50 percent hub cavity fill. (See Figures 5A and 5B.)

NOTE: A template may be used to hold the lubricant in place while filling the hub cavity. (See Figures 5 and 5C.)

! CAUTION :Make sure that there are no air-pocketstrapped under the grease. If pumping equipment is used, ensure the pump does not aerate the grease. Aeration of the grease may result in underfilling.

Install the outer bearing, washers and adjusting nuts. Adjust wheel bearings per TMC’s RP 6�8 or per OEMMaintenance Manual. Verify end play (0.00�” to 0.005”) with a dial indicator. Before installing the hubcap, apply a coating of grease around the wheel bearing adjust-ment nut(s).

Hubcap Considerations: Semi-fluid GreaseUse an appropriate tamper-proof, vented hubcap. These hubcaps prevent gear oils from being accidentally added to grease-filled wheel ends.

NOTE: Because of the hubcap’s special venting capa-bility and the properties of the semi-fluid grease, do not fill the hubcap with grease.

NOTE: If a metal hub cap is used, it is necessary to coat the interior surfaces with a film of grease. Use special care not to cover the vent with grease.

Hub Fill Procedures: Hard Grease Before installing the hub, pack grease into the hub cavity. Fill the circumference of the hub cavity using the bearing races as the proper level guide. (See Figure 6.)

Use lifting equipment to align the hub assembly with the spindle taking care to not damage the seal and spindle threads. Push the hub assembly into position.

Install the outer bearing, washers and adjusting nuts. Adjust wheel bearings per TMC’s RP 6�8 or OEM Main-tenance Manual. Verify end play (0.00�” to 0.005”) with a dial indicator. Apply a coating of grease around the adjusting nut(s).


TMC RP 63� © 2003 – TMC/ATA – Reprinted with Permission

87

Hubcap Considerations: Hard GreaseUse an appropriate tamper-proof, hubcap. These hub-caps prevent gear oils from being accidentally being added to grease-filled wheel ends. Follow the recom-mendation of the seal supplier to determine if the hub-cap should be vented or non-vented.

NOTE: If a metal hub cap is used, it is necessary to coat the interior surfaces with a film of grease. Use special care not to cover the vent with grease.

DRIVEN AXLE LUBRICANT WHEEL ENDCONSIDERATIONS

NOTE: In this Recommended Practice, all drivenaxles are oil lubricated.

Inspection and PreparationIf the wheel end is disassembled, clean and inspect the wheel end components including all bearings, axle shafts, hub and bearing cups, axle, and fasteners, re-moving all contaminants and lubricant residue. Replace seal, axle flange gasket, and all questionable parts. For detail procedures, refer to TMC RP 622.

Component LubricationPre-lubricate the inner and outer wheel bearing cones with clean lubricant of the same type used in the axle reservoir.

! CAUTION : Failure to lubricate bearing correctlyand maintain proper lubrication may result in bearingdamage. For additional information refer to TMC RP6�8 and RP 622.

! CAUTION : In oil bath systems, do not pack bear-ings with grease before installation. Grease will tempo-rarily restrict or prevent the proper circulation of lubricant and may contribute to wheel seal failure.

Hub Fill Procedures: OilInstall the wheel seals, as documented in RP 622. Fill hub cavity with oil. Use lifting equipment to align the hub assembly with the spindle taking care to not damage the seal and spindle threads. Push the hub assembly into position.

While the hub is supported, fill the hub cavity with clean oil and push into position or push into position and then fill the hub cavity.



88

Install the outer bearing, washers and adjusting nuts. Adjust wheel bearings per TMC’s RP 6�8 or OEM Main-tenance Manual. Verify end play (0.00�” to 0.005”) with a dial indicator.

Install the flanged drive axle shaft with a new axle flange gasket. Torque flange nuts to axle manufacturer’s speci-fication. Clean-up any over spills that would give the ap-pearance of a leaking system. Oil is supplied directly to the wheel ends at assembly and through the axle tube during operation. To achieve final fill level, each end of the drive axle must be raised a minimum of eight inches for one minute to move the lubricant into the opposite wheel end. Recheck the main sump for the proper oil level and top off the lubricant level, if required. The oil fill level is always to the bottom of the fill plug or hole in the axle reservoir.

! CAUTION :Do not pack the drive axle wheel bear-ings with grease when the wheel ends will be lubricated with oil from the axle differential. (See RP 622 and RP 6�8.)

NOTE: Always check the axle breather to be sure it is operating properly and completely free of dirt and de-bris.

MAINTENANCE AND INSPECTIONREQUIREMENTSThe following inspection criteria are intended for units whose vocation is strictly on-highway use only. The in-spection criteria are not intended for unitized or pre-set wheel ends, refer to systems manufacturer for inspec-tion and service recommendations.

These recommendations depend on the proper as-sembly of the system, including the proper lubricant fill level.

A. OIL LUBRICATED WHEEL ENDSINSPECTION CRITERIA

Level 1—Simple Inspection (Pre-Trip/In-Service) Walk around vehicle and check wheel-ends for obvious signs of lubricant leakage, such as hubcap gasket and wheel seal areas, oil soaked brake linings. Check for broken or missing components. Any seepage is reason for further inspection and appropriate action.

Take appropriate action if leaks or oil soaked brakelinings are noted.

NOTE FOR DRIVERS: After making an en route stop, walk around the unit and feel the hubs. If there is any significant differences in temperatures or excessive

temperature, contact your maintenance department. When feeling hubs for temperature, seasonal influences should be taken into consideration.

If wheel-ends are equipped with a sight glass on the hub-caps, check to ensure the oil is at the proper fill level.

NOTE: Oil residue may be present at the vent area. This is an indicator that the system is venting properly. This should not be construed as system leakage.

Level 2—100,000 miles or Annual Inspection:For non-driven axles check lubricant level and condition. If lubricant is contaminated replace old lubricant with the same type lubricant. If lubricant condition is good and level is low, fill to the proper level. Check for any signs of leakage at the seal or hubcap gasket areas. Check for oil soaked brake linings.

For driven axles, check for any signs of leakage at the seal or axle flange gasket areas. Also check for leaks at hub fill hole if so equipped. Check for oil soaked brake linings.

Take appropriate action if leaks or oil soaked brakelinings are noted.

B. GREASE LUBRICATED WHEEL ENDSINSPECTION CRITERIA

Level 1—Simple Inspection (Pre-Trip/In-Service)Walk around vehicle and check wheel-ends for obvious signs of lubricant leakage, such as hubcap gasket and wheel seal areas, grease soaked brake linings. Check for broken or missing components. Any seepage is rea-son for further inspection and appropriate action.

NOTE FOR DRIVERS: After making an en route stop,walk around the unit and feel the hubs. If there is any significant differences in temperatures or excessive temperature contact the maintenance department. When feeling hubs for temperature, seasonal influences should be taken into consideration.

Level 2—Detailed External Inspection(Conducted at PM or at least annually)Check wheel-ends for obvious signs of lubricant leak-age, such as hubcap gasket and wheel seal areas, grease soaked brake linings. Any seepage is reason for further inspection and appropriate action. Raise the ve-hicle and check for smooth rolling of wheels. Check for signs of excessive end play in the wheel-end. This does not include removal of the hub cap.

NOTE: Leaking grease may not spread over the huband brake components as with hubs filled with oil. When



89


inspecting for grease leaks the inspection must be done very carefully with the aid of a bright beam of light from a flashlight or droplight.

NOTE: Some grease seals will purge very smallamounts of grease in normal operation. If there is seep-age around the hubcap flange area, take appropriate action to eliminate seepage as directed by your mainte-nance instructions.

If leakage in the seal area is found, remove the wheelend and replace the hubcap gasket, seal and lubricant.Inspect the spindle and bearings for damage and re-place if needed. Anything abnormal requires Level 3 In-spection.

! CAUTION : A clogged vent can damage the wheelseal allowing internal pressure build up in the wheelend.

Level 3—Lube Level Inspection(Per OEM Recommendation)When using grease in a wheel-end the only method to accurately check the lubricant level is by pulling the out-er bearing. If using a hard grease, there is no need for a Level 3 Inspection.

! CAUTION : Failure to remove the outer bearingmay provide a false lubricant level reading.

To verify proper lube level the following proceduresneed to be performed.

�. Before performing any maintenance on the vehi-cle take appropriate action to ensure the vehicle is safely secured.

2. Remove hubcap, hubcap gasket and inspect hubcap for adequate venting capabilities.

3. Verify wheel-bearing end play for conformance to RP 6�8.

4. Record end play measurements.

! CAUTION : Apply the parking brake, if axle is equipped. This will ensure that the wheel/hub assembly is supported and held steady during removal of the spindle nut and outer bearing. This will eliminate the possibility of spindle, bear-ing or seal damage due to the cocking or slip-ping of the wheel-hub assembly.

! CAUTION : Care should be taken so the wheel-end assembly is properly supported.

5. Remove adjusting nuts.6. Remove outer bearing.7. While maintaining proper support to the wheelend

or hub, visually check lube level. In a semi-fluid

grease system, if the lubricant flows out of the hub cavity, the hub cavity should be refilled to the 3 o’clock and 9 o’clock level. This represents 50 percent hub cavity fill. (See Figures 5 and 5A.)

In a semi-fluid grease system, if the grease doesn’t flow, inspect lubricant condition in the hub cavity. Go to Level 4 Inspection if abnormal conditions are noted. If no abnormal conditions are noted, add grease until it flows out of the hub cavity.

NOTE: If changing grease types or brands, con-tact your lubricant supplier to insure compatibil-ity.

8. Clean bearing and inspect for wear and damage. When reassembling industry standard wheel-ends, assemble per RP 6�8.

NOTE: Manufacturer is defined as the final as-sembler of the product or the particular system supplier.

Level 4—Wheel-end Disassembly Inspection(Complete System Tear-down)If any abnormal conditions are found during inspectionLevels �, 2, or 3, remove wheel-end for inspection. Lube change intervals as determined by the manufacturer dic-tate when Level 4 service is performed.

NOTE: Manufacturer is defined as the final assemblerof the product or the particular system supplier.

When reassembling industry standard wheel-ends, as-semble per RP 622 and RP 6�8. Seals and gaskets must be replaced.

Failed Component AnalysisSave prematurely failed parts and lube samples for anal-ysis. The lubricant sample collected should be at least four ounces. A similarly sized new lubricant sample (not previously used) is also required. This will aid in supplier assisted detection and prevention of premature failures. The components’ history of usage should also be pro-vided (i.e., vehicle’s vocation, mileage, maintenance re-cords, and history of inspection and repair/replacement of components such as seals, seal wear rings, lubricant, bearings, etc.).

OPERATIONAL CONSIDERATIONS FORLUBRICANTSService interval ranges from 100,000 miles to five years in over-the-road service, depending on axle type, manu-facturer recommendations, and lubricant performance.


90

Mineral oil based lubricants have lower initial costs than synthetics lubricants, but need to be changed more fre-quently in some equipment. When choosing a lubricant, the fleet needs to consider:

• the manufacturer’s recommendation for the axlemake and model in service.

• the fleet savings associated with extended ser-vice intervals.

• the total cost of the lubricant.

NOTE: Because seal performance may vary when switching lubricants, consult your seal supplier for com-patibility concerns.

Wheel Installation & MaintenanceDISC WHEEL INSTALLATION PROCEDURE – HUB PILOTED DISC WHEEL SYSTEM

�. Check all parts for damage including wheels and rings. Ensure that studs, nuts pilots and mounting faces of hubs, drums and wheels are free of dirt and grease. The hub or drum mounting face must be cleaned and kept flat. Clean hub or drum sur-face and piloted with a wire brush if rust or debris is present. Make sure the wheels are hub piloted wheels with bolt holes drilled straight through with-out ball seats. Stud piloted wheels must not be used as substitutes for hub piloted wheels under any circumstance. Never try to use a hub piloted wheel with stud piloted hub or stud piloted nuts. The result could be loss of torque, a cracked wheel, or possible wheel loss.

Note the condition of the hub and the hub pilots. Replace the hub if worn or cracked bolt holes or a worn hub face are evident, or if the pilots are worn or broken. Check the hub for damage and flat-ness. Replace if the original flat area is reduced in diameter by wear.

2. Wire brush the base of each stud as well as the threads to remove any rust or foreign material which could bind up the wheel nuts.

3. Ensure the brake drum is positioned on the raised step of the pilots, and is seated fully against the hub.

4. Check for damaged studs and stripped stud threads as evidenced by shiny threads. Also look for worn or damaged mounting faces by using a straight edge. Replace any parts which exhibit wear or damage. Ensure replacement studs are the proper ones for the system used. Stud breakage can occur if the wrong studs are used.

If a stud is broken, replace it and the stud on each side of the broken one. If 2 or more studs are broken, replace them all. Use a press to install studs and be sure the hub flange is supported. Aluminum hubs require different stud installation procedures. Consult the manufacturer for recommendations. Stud heads can be bent from hammer blows which will prevent the stud from seating properly and can result in stud failure.

5. Make sure the center hole of the wheel is clean so it will fit easily on the hub pilots.

6. Use correct nuts. Nuts used for stud piloted systems cannot be used in hub piloted systems. Hub piloted wheels use flange nuts for both the single and dual wheel applications. No inner cap nuts are required.

7. Check the wheel nuts. Ensure that multi-piece nuts turn smoothly on their flanges. Discard all nuts with damaged threads.

8. Apply two drops of oil to a point between the nuts and flange and two drops to the last 2 or 3 threads at the end of each stud. Also lightly lubricate the pilots on the hub to ease wheel installation and removal. Do not get lubricant on the mounting face of the drum or wheel.

9. Rotate the hub so that one pilot is at the �2 o’clock position. Place single wheel or inner dual wheel onto the hub being careful not to damage stud threads. Make sure the wheel is fully seated against the drum.

�0. For dual wheels, place the outer wheel onto the hub making sure the hand holds are lined up for easy ac-cess to the tire valves. Make sure the outer wheel is pushed fully up against the inner wheel. Install nuts finger-tight at the 12 o’clock and 6 o’clock positions,

then apply nuts finger-tight on the remaining studs. Snug the nuts to about 50 ft. lbs. following a crisscross sequence as shown in Figure 1. Finally, tighten all the nuts to the recommended torque (see Table 1) using the same crisscross sequence.

��. After the wheels are installed, check to see that both wheels are still seated on to the pilots and are flat against the drum. This can be done by inspecting the seating of the wheels on all four pilots and by turning the wheels and checking for irregularity of the wheel assembly.

�2. After a wheel assembly has been installed, recheck the torque level between 50 and �00 miles of opera-tion and retighten if necessary to the recommended torque using the proper sequence. It is recommended that a torque check be made as part of a vehicle’s scheduled maintenance program or at �0,000 mile intervals, whichever comes first. Individual fleet ex-perience may dictate shorter intervals or allow longer intervals.

�3. If air wrenches are used, they must be periodically calibrated for proper torque output. Use a torque wrench to check the air wrench output. If output is not correct, take the necessary steps to adjust output.

DISC WHEEL INSTALLATION PROCEDURE – STUD PILOTED DISC WHEEL SYSTEM.

�. Check all parts for damage including wheels and rings. Ensure that studs, nuts and mounting faces of hubs, drums and wheels are free of dirt and grease. The hub or drum mounting face must be cleaned and kept flat. Clean hub or drum surface with a wire brush if rust or debris is present. Note the condition of the hub and drum. Replace them if worn or cracked bolt holes or a worn hub or drum face are evident . If a heavy duty ball seat (�-3/�6” spherical radius)

system is used, make sure the wheels are proper for the vehicle. Never mix hub-piloted disc wheels and hubs with ball-seat disc wheels and hubs. The result could be loss of torque, a cracked wheel or possible wheel loss.

2. Wire brush at the base of each stud as well as the threads to remove any rust or foreign material which could bind up the wheel nuts.

3. Check for damaged studs. Replace any parts which exhibit wear or damage. Ensure replacement studs are the proper ones for the system used. Stud break-age can result if the wrong studs are used.

If a stud is broken, replace it and the stud on each side of the broken one. If 2 or more studs are broken, replace them all. Use a press to install studs and be sure the hub flange is supported. Aluminum hubs require different stud installation procedures. Consult the manufacturer for recommendations. Stud heads can be bent from hammer blows which will prevent the stud from seating properly and can result in stud failure.

4. Check the wheel for damage, elongated bolt holes, wear, corrosion, cracks around bolt holes or center hole or torch cuts and replace as necessary. If slight burrs have been raised around the ball seats, use a file to remove them. Be sure not to cut into the flat surface of the wheel mounting face. Wire brush inner and outer cap nuts if rust accumulation is evident. If threads are damaged or corrosion is heavy, discard nuts. Also discard nuts that show damage or wear to ball seats or hex areas.

5. Be certain you have correct fasteners. Nuts used in the hub piloted system cannot be used in the stud piloted system. Single aluminum wheels on ¾” stud use different nuts than steel wheels. Dual aluminum wheels require special inner nuts with greater strength

and length than steel wheel inner nuts (See TMC RP 2�7A, Attaching Hardware for Disc Wheels.)

6. Separate all frozen cap nuts prior to reinstalling the wheel. Do not attempt to reapply wheels that come off with the inner cap nut frozen to the outer cap nut. Each nut must be reinstalled properly with each nut tightened to the proper torque level.

7. Never lubricate wheel or nut ball seats or mount-ing faces. If lubrication is desired, it should be used sparingly only on the threads of the studs and/or nuts. If lubrication is used, consult the wheel manufacturer for torque recommendations.

8. Slide the front wheel or inner dual wheel over the studs being careful not to damage the stud threads. Lift the wheel to center one stud within its bolt hole while installing an inner nut finger tight. Repeat with another nut about 180 degrees away from the first. Install the remaining nuts. Snug up nuts to about 50 ft. lbs. in the sequence shown in Figure 2. Do tighten then fully until all have been seated. This procedure will permit the uniform seating of nuts and ensure the even, face to face contact of the wheels against the hub or drum. Tighten the nuts to the recommended mounting torque (see Table �) using the same criss-cross tightening sequence.

9. Place the outer dual wheel over the ends of the inner nuts and install 2 outer nuts 180 degrees apart finger-tight to locate the wheel. Install the remaining nuts and tighten to 50 ft. lbs. using a crisscross sequence as shown in Figure 2. Finally tighten the outer nuts to the recommended torque (see Table 1) using the same sequence.

�0. After a wheel assembly has been installed, recheck the torque level between 50 and �00 miles of opera-tion and retighten if necessary to the recommended

torque using the proper sequence. To check and re-torque an inner nut, it is necessary to loosen the outer nut first, and then tighten the inner nut. Finally, the outer nuts must be retightened to the proper level.

��. It is recommended that a torque check be made as part of a vehicles scheduled maintenance program or at 10,000 mile intervals whichever comes first. Indi-vidual fleet experience may dictate shorter intervals or allow longer intervals.


SPOKE WHEEL/DEMOUNTABLE RIM SYSTEM IN-STALLATION PROCEDURES

�. Ensure that the correct spacer band, rim, and clamp combinations are being used for the application. Check all parts for damage. Ensure that studs, nuts, clamps and 28 degree mounting surfaces of the cast spoke wheel and rim are sound, clean and free from grease. Clean the cast spoke wheel with a wire brush if scale is present. The spacer band should be clean and free from distortion.

2. Replace any damaged or distorted part. Do not weld, heat, or braze.

3. Install the rim after the tire is inflated. Multi-piece rims may distort at high inflation and become difficult to slip onto the cast spoke wheel. If this occurs deflate the tire to not less than 80% of the recommended inflation until the rim is mounted on the truck. If dif-ficulties still exist, contact the rim manufacturer for recommendations. Always adhere to OSHA standard No. 29 CFR, Part �9�0.�77 “Servicing Single-Piece and Multi-Piece Rims/Wheels” and TMC RP 209B,

Tire and Rim Safety Procedures.

4. For front assemblies, align the locators between the spokes, then place the rim and inflated tire on the cast spoke wheel.

5. For rear assemblies, align the locators between the spokes, then place the inside rim over the cast spoke wheel as far as possible. Push the spacer band over the cast spoke wheel with a constant pressure on both sides. Guard against cocking. The band should fit snugly to the spokes and against the inside rim gutter edge. Place the outer dial rim in position.

Note: 8.5 and wider tube type rims may require special size spoke wheels and spacer bands.

6. Secure clamps evenly in position and snug-up the nuts in the sequence shown in Figure 3.

7. Do not tighten nuts fully until all of them have been snugged up This will permit the rims to properly align themselves on the 28 degree mounting surfaces of the cast spoke wheel. Correct alignment if necessary

at this time. Tighten the nuts to the recommended torque (see Table 2). Maintain them at that level through planned, periodic checks. Be sure not to exceed the recommended torque values. If the heel of the rear clamps bottom out before reaching 80% of the recommended torque levels, ensure that proper clamps and spacers are being used. Complete the tire inflation to the recommended level.

8. After a demountable rim has been installed, recheck the torque on the clamp nuts between 50 and �00 miles of operation and retighten the nuts to the proper torque level using the proper nut tightening sequence.

9. It is recommended that a torque check be made as part of a vehicles scheduled maintenance program or at 10,000-mile intervals whichever comes first. Indi-vidual fleet experience may dictate shorter intervals or allow longer intervals.


Note: Demountable rims are not all the same offset. Use the proper size tires, rims, spacer and clamps to provide tire and vehicle clearance.

Notes:

�. If using specialty fasteners, consult the manufacturer for recommended torque levels.

2. Tightening wheel nuts to their specified torque levels is extremely important. Under tightening which results in loose wheels can damage wheels, studs and hubs and can result in wheel loss. Over tightening can damage studs, nuts and wheels and result in loose wheels as well.

3. Regardless of the torque method used, all torque wrenches, air wrenches and any other tools should be calibrated periodically to ensure the proper torque is applied.

Brake Drum & Rotor Identification & Replacement

Brake Drum Identification

�. When specifying replacement brake drums & rotors the following information is required: • The manufacturer’s name • The manufacturer’s part or casting number • Description of any other markings appearing on the drum or rotor.

2. If that information isn’t available, the following is the next best: • Vehicle manufacturer • Vehicle model • Axle or spindle size • Whether disc or spoke wheel application • Brake size and type of actuation (S-cam, Wedge, Air, Hydraulic, etc.) • Whether inboard or outboard mounting

3. If that information isn’t available, the following is required. • It will be necessary to make accurate measurements to determine the type and size of

the brake drum or rotor needed, particularly if the part number can not be determined. The photographs following show the items to measure and check prior to ordering a new brake drum or rotor.

Brake Drum Failure Analysis

Heat-checking is a nor-mal condition of the brake drum caused by constant heating and cooling of the braking surface.

Heat checking does not impair brake perfor-mance, reuse drum if within tolerance.

If deep cracks have de-veloped, replace drum immediately

This problem is signified by a bluish color and disfigurement of the brake parts.

Heat Checking

Mishandling (new drum).

Excessive heating and cooling.

Brake balance.

Driver abuse.

Replace brake drum.

Check to see if drum is adequate for the applica-tion.

Check for pneumatic or torque balance problems.

Driver training

Replace cracked drums immediately.

Upon inspection, the drum is found to have cracked all the way through the entire wall.

Cracked Drums

Excessive heat from dragging brakes or brake imbalance.

Swollen linings.

Look for weak or broken return springs or binding brake actuation.

Consult lining manufac-turer.

Drum can be used if deep cracks are not pres-ent.

Blue Drums This problem is signified by a bluish color and disfigurement of the brake part.

Problem Probable Causes Recommended Actions


99

Improper lining friction rating.

Drum resurfaced with too fine of a micro-finish.Light contact of linings to drum.

Consult vehicle or lin-ing manufacture for an alternate lining material. Micro-finish should be �50-200 RMS. Check condition of return springs, camshaft bush-ings, air system and shoe to drum contact. Remove the gloss with eighty (80) grit emery cloth.

Recognized from a mirror-like finish on the braking surface.

Polished Drums

Heat distortion

Drum has been dropped or stored on its side.

Improper chucking when turning drum.

Turn brake drum if within limits or replace.

Variations in drum diameter at different points on the braking surface

Out-of-round Drums

Normal wear condition (age).

Replace brake drums and brake linings.

Uneven lining wear, or braking surface diam-eter measures in excess of allowable limits.

Oversize Worn Drums

Martensite is formed by rapidly heated brakes to approximately the �400° F range followed by rapid cooling. This condition is caused by brake drag or torque imbalance.

Replace brake drum. Check for dragging brake, check balance between tractor/trailer and wheel to wheel (i.e. air distribution, brake ad-justment, and power A/L factors.)

The brake surface shows black spots which are slightly raised and are hard and brittle

Martensite Spots

Leaking oil/grease seal or improper lubrication of brake components.

Repair source of oil or grease leak, clean the brake drums and replace the linings.

The drum shows discolored spots on sur-face, with oil or grease on brake assembly

Grease Stained Drums

Grooves, loose rivets or bolts, or foreign material in rivet holes. Abrasive material in brake drum.

Poor quality brake lining.

Repair or install rivet plugs.

Dust shield may cause or cure this problem.

Consult lining manufac-ture.

Turn brake drum if within limits or replace.

The problem is indicated by a grooved ap-pearance on the brake surface
