C. Repair

(1) Minor Repair

(a) Minorrepairisthatwhichmaybedonesafelyinthefieldbyacertifiedaircraft mechanic.

(b) Refer to Hartzell Manual 135F (61-13-35), Composite Blade Maintenance Manual, for information on repair criteria for composite blades, or Hartzell Manual 133C (61-13-33) for aluminum blades.

NOTE: Removingsignificantamountsofmetalfromanaluminumblademay render it below minimum width or thickness. The propeller needs to be inspected by an approved propeller repair station to determine whether it is below published minimums.

(2) Major Repair

(a) Major repair is correction of damage that cannot be done by elementary operations.

(b) MajorrepairworkmustbeacceptedbyanFAAcertifiedindividual,preferablyonethatholdsaFactoryTrainingCertificatefromHartzellPropeller. The servicing facility must meet facility, tooling, and personnel requirements and is required to participate in Hartzell Sample Programs asdefinedintheHartzellStandardPracticesManual202A(61-01-02).

D. Component Life

NOTE: Certain components, or in some cases an entire propeller, may be life limited. It is a regulatory requirement that a record of the total time in service be maintained for all life limited parts.

(1) Component life is expressed in terms of total hours of service (Time Since New, TSN) and in terms of hours of service since overhaul (Time Since Overhaul, TSO).

(a) TSN/TSO is considered as the time accumulated between rotation and landing, i.e.,flighttime.

(2) Bothreferencesarenecessaryindefiningthelifeofthecomponent. Somepartsare"lifelimited,"whichmeansthattheymustbereplaced afteraspecifiedperiodofuse(TSN).

(3) When a component or assembly undergoes an overhaul, the TSO is returned to zero hours. Total Time Since New (TSN) can never be returned to zero.

NOTE: Repair without overhaul does not affect TSO or TSN.

(4) Total Time Since New (TSN) records must be maintained in the propeller logbook along with Time Since Overhaul (TSO).

(5) Blades and hubs are sometimes replaced while in service or at overhaul. Maintaining separate TSN and TSO histories for a replacement hub or blade is required. Other propeller components do not require time tracking unless specificallynotedinHartzellservicepublications.

(a) Hub replacement

1 If the hub is replaced, the replacement hub serial number must be recorded (the entry signed and dated) in the propeller logbook. The propeller will assume the serial number of the replacement hub.

NOTE: Propeller assembly serial numbers are impression stamped onthehub.SeethePartsIdentificationandMarkingchapter of Hartzell Standard Practices Manual 202A (61-01-02) for stamping information.

2 The TSO and TSN of the replacement hub must be recorded and maintained in the propeller logbook. The TSN and TSO of the remaining propeller components are not affected by the hub replacement and must be maintained separately.

1. Description

Hartzell steel hub propellers are constant speed assemblies that use a steel component as the central hub. See Figure 1. Propeller blades and bearing assemblies are assembled on the hub arms and are held in place by two-piece steel clamps. A steel cylinder is threaded onto the steel hub and an aluminum piston is placed over the cylinder. Link arms connect the piston to the steel clamps to control blade angle. Depending on the model of the propeller, steel hub assemblies may use counterweights or a feathering spring or both. See Figure 2.

2. Operation

A. Constant Speed Non-Feathering With Counterweights

(1) Constant speed non-feathering assemblies with counterweights use oil pressure to decrease the blade angle and centrifugal force on the counterweights to increase the blade angle.

(2) When the engine speed drops below the RPM for which the governor is set, the force of the speeder spring overcomes the rotational force of the governor flyweights. The flyweights tilt inward and lower the pilot valve, which allows governor oil to increase pressure on the propeller piston, moving the piston outward. The action of the piston decreases the blade angle and allows the engine to return to the on-speed setting.

(3) When the engine speed increases above the RPM for which the governor is set, the governor flyweights overcome the force of the speeder spring. The governor flyweights tilt outward and raise the pilot valve which allows governor oil pressure to decrease. Centrifugal force acting on the counterweights increases the blade angle and allows the engine to return to the on-speed setting.

(4) The -1 steel hub turbine propeller models are constant speed non-feathering with counterweights.

B. Constant Speed Feathering

(1) Constant speed feathering assemblies use oil pressure to decrease the blade angle. A combination of counterweights and the feathering spring are used to increase the blade angle.

(2) Feathering is accomplished by releasing the governor oil pressure. When the feathering mechanism is activated, the governor pilot valve raises the lift rod and allows governor oil to be ported from the propeller. The combined force of the counterweights and feathering spring moves the blades to the feather position.

(3) The time necessary to feather the propeller is dependant on the size of the oil passage from the propeller to the engine and the force exerted by the spring and counterweights. The feathering process is normally accomplished within three to ten seconds.

(4) Unfeathering the propeller is accomplished by repositioning the governor control to the normal flight range. The engine is restarted and after several revolutions the governor increases oil pressure and moves the blades out of the feather position.

(5) The -2 steel hub turbine propeller models are constant speed feathering.



C. Constant Speed Reversing

(1) Constant speed reversing assemblies are feathering propellers that allow increased blade angle travel into the reverse pitch range. See Figure 3. Also, a hydraulic low pitch stop is introduced.

(2) The hydraulic low pitch stop prevents the pitch from entering the reverse range unless commanded. This unit consists of a beta valve that eliminates governor oil to the propeller when the pitch reaches the low position. The beta valve is actuated by a linkage connected to the piston.

(3) The -3, -5, and -7 steel hub turbine propeller models are constant speed feathering and reversing.

(a) The beta feedback linkage for the -3 model is external to the propeller hub. Linear motion is transmitted from the rotating hub to the fixed engine by the collar and carbon block assembly.

(b) The beta feedback linkage for the -5 and -7 models consists of a beta tube mounted concentric with the propeller shaft that serves as an oil passage.

3. Model Designation System

A. Propeller Model Designation

Hartzell uses a model number designation system (outlined in Figure 4) to identify specific propeller and blade assemblies. An example model number would be HC-B5MP-3A/M10282A+6, where the slash mark separates the propeller and blade designations. For specific information concerning the Hartzell model designation system, refer to the Introduction chapter of Hartzell Application Guide Manual 159 (61-02-59).

The propeller model number is impression stamped on the propeller hub. The blade model number is impression stamped on the butt end of the blade, as well as ink stamped or labelled on the camber side of the blade.

B. Blade Shank Designation

Hartzell blades are often referred to as "D" shank, "Y" shank, etc. For most blades, the shank type is identified in the prefix letters of the blade model designation. For example, blade model number T10282 generally means the blade has a "T" shank. However, there are exceptions to this rule. For example, "Y" shank blades do not use the letter "Y" in the model designation.

For information concerning blade shank designs, refer to Hartzell Aluminum Blade Manual 133C (61-13-33), or Hartzell Composite Blade Manual 135F (61-13-35).

C. Conversion From V Shank to MV Shank

"V" shank models, which have double-shoulder configuration, have additional repetitive inspections required by Airworthiness Directive 97-18-02.

"MV" shank models, which have a single-shoulder configuration, are not affected by the Airworthiness Directive.

"V" shank blades can be converted to "MV" shank to avoid the inspections required by the Airworthiness Directive. After conversion, the propeller model number changes to reflect the conversion. For example, HC-A3VF-7/V8433N becomes HC-A3MVF-7/MV8433N.

1. Troubleshooting Guide

The purpose of this guide is to help isolate probable causes and suggests possible remedies for some of the more common propeller service problems. In all cases, the remedy for a problem should follow the procedures detailed in the applicable section of this manual.

A. Excessive Friction in Hub Mechanism

Lack of blade thrust bearing lubrication

or Piston O-ring is causing excessive friction

or Piston phenolic bushing is scraping against the wall of the cylinder

Add approved grease to the blade clamp lubrication fittingsperStandardPractices Manual 202A (61-01-02).

Replace the piston O-ring.

Check the ID of the phenolic bushing. See the serviceable limits in the Check chapter of this manual.

Check the roundness of the bushing. Follow replacement procedure, if necessary.

Check the OD of the cylinder. See the dimensional limits in the Hard Chromium Replating chapter of Hartzell Standard Practices Manual 202A (61-01-02) . Follow the cylinder replacement procedure, if necessary.

Remove any evidence of wearorchafingonthecylinder. Follow the repair procedure, or replace if necessary.

Problem Probable Cause Remedy



TROUBLESHOOTING GUIDE

A. (Continued)

B. Failure to Feather

C. Failure to Change Pitch (Sluggish RPM change to increase or decrease)

or Blade O-ring is not allowing the clamp and blade to rotate freely on the hub.

or Balls in the blade split-bearing are unusually rough, corroded, or chipped.

or Insufficientclearance between various moving parts in the pitch change mechanism. or The pilot tube has slipped out slightly and is rubbing hard against the end of the cavity in the blade.

Excessive Friction in moving parts

or Feathering spring is broken

Excessive friction in moving parts.

or Oil passages are not clear and open

Disconnect the blade clamp from the piston by removing the piston link pin. The clamp and blade should rotate on the hub with light to moderate hand pressure. If not, replace the C-3317-232 blade O-ring with a C-3317- 231 O-ring. If friction is still present, replace the O-ring with a C-3317-230 O-ring.

Replace the blade split-bearing assembly.

Check moving parts individually for interference, and establish correct clearancesasspecifiedinthismanual.

Follow Disassembly procedure for the hub unit to expose the hub arm and pilot tubes. Inspect each pilot tube for wear and length of protrusion from the hub arm, as specifiedinHartzellStandardPractices Manual 202A (61-01-02). Replace the pilot tube as required.

See problem A, "Excessive Friction in Hub Mechanism".

Replace the feathering spring.

See problem A, "Excessive Friction in the Hub Mechanism" and problem B "Failure to Feather".

NOTE: Isolate the friction in each blade by uncoupling the piston from each link arm and testing each blade individually before disassembling the propeller.

Inspect the hydraulic system.





D. Surging RPM or Torque

E. Propeller Windmills in Excess of Airframe Manufacturer's Specifications

Excessive friction in the pitch change mechanism.

or Air is trapped in the propeller actuating piston or in the engineshaft.

or The socket head cap screw in the guide collar is too tight.

Incorrect feather blade angle

See problem A, "Excessive Friction in the Hub Mechanism"

The engine should have a provision for allowing trapped air to escape from the hydraulic system during one-half of the pitch cycle.

Beforeeachflight,exercisethepropeller by changing pitch or feathering.

Loosen the socket head cap screw to the minimum torque.

See "Setting Feather Angle of Blades" in the Assembly chapter of this manual.

This procedureapplies to propellermodelsHC-B3TN-5N( ),HC-B3TN-5M( ), andHC-B3TN-5P( ),HC-B3TN-5U( ),HC-B3TN-5W( ) .

B. Discussion

Thepropeller assemblymayexperienceaproblemwhere thepistonguide collarappears to be looseor tends to rotate, causingbindingor improper actionof thestart lockassembly.When this problem is reported, or at thenext overhaul, thefollowing procedure will strengthen the system and eliminate the possibility of rotational movement.



C. Procedure

(1) Disassemble thepropeller.

(2) Inspect the cylinder and verify dimensionZ-1 inFigure6-10.

(3) Inspect theguide collar and verify dimensionx inFigure6-11.

(4) Inspect theguide collar support ringand verify dimensionT inFigure6-12.

(5) After inspecting theparts, rework them toensureproper cylinder-to-hubandcylinder-to-guide-collar fit and correct guide collar rotational play.

(a) Turnandmachine the cylinder in a latheuntil Z-1dimensionequals0.462±0.010 inch (11.73±0.25mm).

2. Special Case: Reassembly When the Blades Have Been Removed for Shipping

The propeller has been assembled and balanced at the factory. The blade angles relative to the clamps have been marked with matching red tape attached to the clamp and blade shank. Grease has been installed in the blade-hub system. Matching numbers have been put on each blade and corresponding clamp.

For convenience of shipping all blades have been removed from the assembly. The clamps have been reinstalled on the hub. The blade ends are wrapped to preserve the grease and keep out foreign materials.

When the propeller is received by the customer, the following instructions are to be followed:

A. Step A applies to propeller models HC-B(3,4)( )W-3( ) only:

NOTE: If the spacer is already attached to the hub flange, begin with step 2.B.

(1) If the spacer (455) is not attached to the hub flange, install the spacer as follows:

NOTE: If the dowel pins are already installed in the spacer, begin with step 2.A.(1)(b).

(a) Press two dowel pins (415) into the spacer (455). See Figure 7-34 for the location of the dowel pins.

(b) Lubricate the O-ring (405) with CM12 and install it in the groove in the spacer (455) that interfaces with the face of the hub flange. See Figures 7-34 and 7-35.

(c) Position the spacer (455) over the hub mounting studs (435), with the O-ring (405) facing the hub flange.

(d) Position the spacer on the hub flange.

1 If the hub flange has two 8-32 threaded holes present, position the spacer (455) so that the spacer attachment holes align with the two 8-32 threaded holes in the hub flange. See Figure 7-34.

2 If the hub flange does not have 8-32 threaded holes present, align the stud clearance holes with the hub-mounted studs (435) in the hub flange, and align the two spacer-mounted dowel pins (415) with any two dowel pin clearance holes in the hub flange. See Figure 7-34.

CAUTION: MAKE SURE THE O-RING (405) STAYS IN THE GROOVE IN THE SPACER (455). IF THE O-RING IS TWISTED OR PINCHED, OIL LEAKAGE WILL RESULT WHEN THE PROPELLER IS OPERATED ON THE AIRCRAFT.

(e) Slide the spacer (455) tight against the hub flange.


ASSEMBLY 61-10-18 Page 7-8Rev. 11 Oct/01

(f) If the hub flange does not have threaded screw attachment holes (Figure 7-35) present to attach the spacer (455) perform the following steps:

1 Apply masking tape around the outside diameter of the spacer (455) and the hub flange to keep the spacer (455) on the propeller assembly when it is installed on the rotatable fixture.

2 Proceed to step 2.B.

(g) If the hub flange has two 8-32 threaded holes (Figure 7-35) present to attach the spacer (455) to the hub flange, perform the following steps:

1 Insert a flat head screw (465) through each screw hole in the spacer (455) and into the 8-32 threaded hole in the hub flange. See Figures 7-34 and 7-35.

CAUTION: MAKE SURE THE FLAT HEAD SCREWS (465) DO NOT PROTRUDE ABOVE THE ENGINE SIDE SURFACE OF THE SPACER (455).

2 Tighten the flat head screws (465) until snug.

3 If after they are tightened, one or both of the flat head screws (465) protrude above the engine side surface of the spacer, perform the following steps:

a Remove both flat head screws and rotate the spacer 180 degrees, aligning the screw holes in the spacer with the 8-32 threaded holes in the hub flange.

b Insert a flat head screw (465) through each screw hole in the spacer (455) and into the 8-32 threaded hole in the hub flange.

c Tighten the flat head screws (465) until snug.

d If after they are tightened, one or both of the flat head screw (465)still protrude above the engine side surface of the spacer, remove both screws.

e Apply masking tape around the outside diameter of the spacer (455) and the hub flange to keep the spacer on the propeller assembly when it is installed on the rotatable fixture.



CAUTION 1: USE EXTREME CARE TO AVOID DAMAGE TO THE MOUNTING STUD (435) THREADS WHEN PLACING THE HUB ON THE ROTATABLE FIXTURE.

CAUTION 2: KEEP THE MOUNTING STUD THREADS CLEAN AND FREE OF GREASE OR DIRT.

B. Install the hub on the rotatable fixture of a propeller assembly table.

CAUTION: ON PROPELLER MODEL HC-B(3,4)( )W-3( ), DO NOT USE LOCKING NUTS ON THE MOUNTING STUDS TO SECURE THE HUB TO THE ROTATABLE FIXTURE. REPEATED TORQUE/DRAG WILL WEAKEN THE EPOXY BOND ON THE MOUNTING STUDS, RESULTING IN POSSIBLE STUD-TO-HUB BOND FAILURE.

NOTE: On propeller model HC-B(3,4)( )W-3( ), install only non-locking 9/16-18 UNF-3B nuts on the mounting studs (435), just tight enough to secure the hub to the rotatable fixture.

C. Remove one of the clamps from the hub. Clean off any grease from the outer diameter of the blade shank.

D. Install the blade onto the hub, matching the blade number with the corresponding clamp number. Install the clamp onto the blade using new clamp gaskets, which are furnished.

E. Follow instructions in Assembly chapter of this manual for blade installation.

F. Repeat procedure for other blades to be installed.

G. Install link arms to connect piston to blade clamps.

H. Check blade angles by following the instructions in the Assembly chapter of this manual.

I. Torque and safety all bolts following instructions in Assembly chapter of this manual.

J. Torque test the blade relative to the clamp by following instructions in Assembly Chapter of this manual.

3. Hub Reassembly

A. Follow the procedure in the Steel Hub Overhaul chapter of Hartzell Standard Practices Manual 202A (61-01-02).

B. Refer to the Repair chapter of this manual for information about the mandatory hub replacement program.

4. Reassembling Blade and Flange Mounting Parts

A. Models ending in -2, -3, -5, and -7. (1) Install the hub on the rotatable fixture of the assembly table.

NOTE: On HC-B(3,4)( )W-3( ) models only: If mounting studs (435) are present in the propeller hub flange, the spacer (455) must be installed on the hub flange before the hub can be installed on the rotatable fixture of the assembly table. Refer to the "Special Case: Reassembly When the Blades Have Been Removed for Shipping" section of this chapter for spacer installation instructions.

CAUTION: BE SURE THE INTERNAL RECESS OF THE BEARING GUIDE RING FACES OUTBOARD WHEN THE GUIDE RING IS SLIPPED OVER THE BLADE ARM FLANGE OF THE HUB UNIT (500).

(2) Use a light mallet and special tool TE309, as shown in Figure 7-1, to drive a blade retention split-bearing guide ring (610) onto one blade arm flange of the hub unit (500).

NOTE: Drive the guide ring far enough onto the blade arm flange that the ring forms a narrow channel on the inboard surface of the flange.

(3) Repeat this guide ring installation procedure for the other blade arm flanges on the hub.

(4) Use lubricant CM12 to lightly grease the inboard surface of each blade arm flange.

(5) Place the halves of an outboard bearing race (matched set) in position over one hub arm.

NOTE: The break-line for the bearing race halves should be perpendicular to the table top.

(6) Use a combination of tools TE309 and TE108 to press the guide ring far enough onto the outboard bearing race to allow insertion of the wire retention ring (620) into the groove in the blade arm flange See Figure 7-1.

(7) Install the wire retention ring.(8) Use tools TE309 and TE108 with spacer A-972, as shown in Figure 7-1,

to pull the bearing guide ring outboard far enough to allow the wire retention ring and the guide ring to contact each other.

CAUTION: THE WIRE RETENTION RING MUST BE FULLY ENCLOSED TO ENSURE IT IS NOT PINCHED.

(9) Check to make sure the wire retention ring is fully enclosed.



(10) Lubricate the blade O-ring (560) with lubricant CM12 and slide it over the blade arm flange of the hub to a location inboard of the thrust bearing. Leave it there for use later in the reassembly.

(11) Repeat Steps 4.A.(2) through 4.A.(10) for the other hub arms.(12) Remove the hub unit from the rotatable fixture on the assembly table and

use special tool TE309 to hold the unit vertical. See Figure 7-2.

NOTE: The arm of the hub being fitted with bearing races must be facing down so that the hub flange and guide ring form a "cavity" that will hold the bearings.

(13) For the HC-B3TN-3( ) propeller as installed on the Beech T-34C aircraft only, replace the A-1851-T bearing race with an A-1851 bearing race (580). Add the letter "C" after the propeller hub serial number to indicate that the replacement was made.

WARNING: THE BREAK LINE OF THE BEARING-HALVES MUST BE AT A RIGHT ANGLE TO THE BREAK LINE OF THE BLADE CLAMP-HALVES.

CAUTION 1: ANY GAP BETWEEN THE HALVES OF THE OUTBOARD BEARING RACE SHOULD BE NO GREATER THAN 0.001 INCH (0.03 MM).

CAUTION 2: ALL BEARING BALLS INSTALLED IN A SINGLE BEARING MUST BE OF THE SAME GAUGE. BEARING BALLS SUPPLIED BY HARTZELL ARE OF THE SAME GAUGE.

(14) Install the ball bearing spacer (600) and the required number of bearing balls onto the outboard bearing races (580), taking care not to scratch the races.

(15) Apply a slight amount of sealant CM93 to the broken edges of the inboard bearing race (matched set). Wipe clean any excess sealant that may extrude into bearing area when the bearing halves are joined.

CAUTION: THE OPENING OF THE RETENTION RING MUST BE AT A 90 DEGREE ANGLE TO THE PARTING LINE OF THE INBOARD BEARING RACE.

(16) Place inboard halves of bearing race around one blade arm of the hub unit and install the wire bearing retention ring (570) to hold the halves in place.

CAUTION: EXCESSIVE USE OF SEALANT COULD CAUSE UNEVEN SEATING BETWEEN BLADE CLAMP AND BEARING RACE.

(17) Apply a small bead of sealant CM93 to the inboard bearing race at chamfer (break point) in order to evenly fill the void in the chamfered area of the race.


ASSEMBLYPage 7-13

Rev. 11 Oct/0161-10-18

(18) Slide the blade O-ring (560) outboard in place against the bearing race.(19) Wrap wide masking tape around the outside diameter of the bearing

assembly to hold the parts in place.(20) Repeat these assembly procedures for each of the other blade arms on

the hub unit.

5. Reassembling the Spinner Support Plate

NOTE: Refer to special instructions for HC-B4TN-5(G&J)L/LT10282N-5.3R in this chapter.

A. Models Ending in -2

CAUTION 1: MAKE SURE EACH HALF OF THE SPLIT SPINNER SUPPORT PLATE HAS THE SAME SERIAL NUMBER.

CAUTION 2: INSTALL THE SPINNER SUPPORT PLATE ON THE HUB MOUNTING FLANGE AT A POSITION WHICH WILL ALLOW THE BETA RODS TO PASS BETWEEN THE HUB ARMS DURING LATER ASSEMBLY PROCEDURES.

(1) Fasten the spinner support plate (380) to the hub mounting flange in ten places with hex head bolts (360).

NOTE: A new spinner mounting plate is supplied with the bulkhead mounting holes undersized. All twelve holes must be drilled with a 0.250 drill. A previously used spinner mounting plate will already have these holes drilled.

(3) When the spinner support plate is accurately aligned with the hub mounting flange, torque all ten hex head bolts (360) per the Torque Values Table in the Fits and Clearances chapter of this manual.

(4) Safety-wire the bolts together with 0.032 inch minimum diameter stainless steel wire (CM131).

B. Models Ending in -3

CAUTION 1: INSTALL THE SPINNER SUPPORT PLATE ON THE HUB MOUNTING FLANGE AT A POSITION WHICH WILL ALLOW THE BETA RODS TO PASS BETWEEN THE HUB ARMS DURING LATER ASSEMBLY PROCEDURES.

CAUTION 2: MAKE SURE EACH HALF OF THE SPLIT SPINNER SUPPORT PLATE HAS THE SAME SERIAL NUMBER.

(1) Insert a plastic-bushed steel guide lug (340) at each of the three or four locations in the split spinner support plate (380).

NOTE: Insert guide and lug from the hub side of the split spinner support plate (380).

(2) On the table side of the spinner support plate, secure each guide lug in place with a snap ring (390). Check that snap ring is in a position where it cannot become jammed between the hub and spinner support.

(3) Fasten the spinner support plate to the hub mounting flange in ten places with hex head bolts (360) and socket head cap screw(s) (365).

NOTE 1: A three-blade propeller has one socket head cap screw and nine hex head bolts as fasteners. The spinner support plate half (380) with a single guide lug hole will use the single socket head cap screw adjacent to the installed guide lug (340). A four-blade propeller has four socket head cap screws and six hex head bolts. Because the screw(s) are installed adjacent to a nearby guide lug (340), this does not allow the use of an open wrench to tighten the hex head bolt(s) (360).

NOTE 2: Do not tighten the hex head bolts at this stage of assembly.



(4) For a three bladed propeller, use fixture TE182 to locate the spinner support plate (380). For a four bladed propeller, use fixture TE183 to locate the spinner support plate. Drill the spinner bulkhead mounting holes in the spinner support plate if required.

NOTE: A new spinner mounting plate is supplied with the bulkhead mounting holes undersized. All twelve holes must be drilled with a 0.250 drill. A previously used spinner mounting plate will already have these holes drilled.

(5) When the spinner support plate is accurately aligned with the hub mounting flange, torque all hex head bolts (360) per the Torque Values Table in the Fits and Clearances chapter of this manual.

(6) Drill the screw(s) with a #42 drill and safety them and the hex head bolts with safety wire CM131.

(18) Safety each socket screw.

(a) On -2, -3, and -7 models, safety each socket screw with a cotter pin (710) in such a way that the cotter pin contacts the clamp-half and prevents any tendency for the screw to back out of the clamp.

NOTE: Three loops of safety wire CM131 may be used as an alternative to safety the socket screws, if the cotter pin causes clearance problems.

(b) On -5 models, use three loops of safety wire CM131 to safety the socket screw; a cotter pin causes clearance problems.

NOTE: For -5 models where the clamp socket screw head has been ground for clearance purposes, lightly tap the loops of safety wire using a hammer to flatten them, so they will not contact the start lock bracket.

(19) On all models except HC-B3TN-5CL, and -5DL

(a) Attach the stop plate (1230) to the clamp (700) using hex head bolts (1220).

(b) Torque the hex head bolts (1220) in accordance with the Torque Table in the Fits and Clearances chapter of this manual.

(c) Safety the hex head bolts (1220) with stainless steel wire CM131.

(20) On models HC-B3TN-5CL, and -5DL only:

Due to normal manufacturing tolerance buildup, the stop plate (1230) may not properly align on the clamp, and the end of the stop plate may contact the shoulder of the link arm. When this happens, material must be removed from the stop plate to obtain clearance. See Figure 7-11.

(a) Attempt to align the holes in the stop plate (1230) with the holes on the outboard end of the clamp.

(b) If the holes in the stop plate (1230) do not align with the holes in the outboard end of the clamp, remove only enough material from the end of the stop plate to allow alignment, and to obtain clearance between the stop plate and the shoulder of the link arm.

(c) Attach the stop plate (1230) to the clamp (700) using hex head bolts (1220).

(d) Torque the hex head bolts (1220) in accordance with the Torque Table in the Fits and Clearances chapter of this manual.

(e) Safety the hex head bolts (1220) with stainless steel wire CM131.(21) Repeat these blade clamp reinstallation procedures for each of the

11. Assembling Feathering Spring

NOTE: A special fixture, TE59, is required for compressing the feathering spring assembly.

A. This is a general procedure that applies to all models covered in this manual. Because there are several different types of feathering spring assemblies, some portions of the instructions may not specifically apply to the model you are assembling.

CAUTION: SEE THE REPAIR, CHAPTER OF THIS MANUAL FOR INFORMATION ON MANDATORY PITCH CHANGE ROD REPLACEMENT.

(1) Slide the spring retainer cup (1440) onto the pitch change rod (1410).(2) Install the thrust bearing (1420) onto the pitch change rod (1410).(3) If applicable, add the spacer (1430).(4) Add spring spacers (1450) as needed.

NOTE: The exact number of spacers needed is not determined until the counterweight angle is set (later assembly procedure); however, the number of spacers needed will most likely be the same as the number of spacers removed during propeller disassembly.

(5) Place the spacer tube (1460) on the pitch change rod (1410).(6) Slide the feathering spring(s) (1460 and 1490) over the spacer tube

(1460)

E. Application of Blade Angle Reference Tape

CAUTION: DO NOT CONFUSE REFERENCE BLADE RADIUS WITH BLADE STATION. REFERENCE BLADE RADIUS AND BLADE STATION OF THE SAME NUMBER MAY NOT ALWAYS INDICATE THE SAME LOCATION ON THE BLADE.

Reference blade radius is measured from the center of the propeller hub to a predetermined reference location on the blade for blade angle measurement.

Blade stations are used during the repair or overhaul process of a blade to define a blade span location for dimensional measurement.

(1) Establish a reference blade radius location

(a) Refer to the Aircraft Type Certificate Data Sheet or the Hartzell Propeller Application Guide, Manual 159 (61-02-59), for the reference blade radius location specified for the applicable aircraft installation.

(b) Beginning with Blade One, measure from the center of the propeller hub to the reference blade radius location specified. See Figure 7-21.

(c) Apply a yellow blade angle reference tape CM160 to the face side of the blade at the reference blade radius location, perpendicular to the blade center line. See Figure 7-21.

NOTE: Place the reference tape CM160 so that the reference blade radius location runs through the center line of the tape.

(d) Repeat steps 12.D.(1)(b) and 12.D.(1)(c) for the remaining blades in the hub assembly.

(e) Place a pattern cut-out over each blade angle reference tape CM160 and spray each yellow blade angle reference tape CM160 with clear lacquer CM129 to prevent peeling.

13. Setting Counterweight Angle and Blade Pitch

A. All models except those ending in -7

CAUTION: AT THIS STAGE OF ASSEMBLY THE OUTBOARD CLAMP BOLTS HAVE NOT BEEN TIGHTENED, BECAUSE ADJUSTMENTS OF COUNTERWEIGHT ANGLE AND BLADE PITCH USUALLY INVOLVE SOME DISASSEMBLY PROCEDURE.

WARNING: TO PREVENT THE PROPELLER FROM “STICKING” IN REVERSE, SET CORRECT COUNTERWEIGHT ANGLE WITH REFERENCE TO THE PROPELLER CENTER LINE WHEN THE PISTON IS IN FULL REVERSE POSITION . SEE FIGURE 7-22. REFER TO HARTZELL APPLICATION GUIDE, MANUAL 159 (61-02-59), FOR CORRECT ANGLE.

NOTE: Counterweight angles are not adjustable on models ending with -7. For those models ending with -7, the angles are determined by contact between the piston rod washers and the rear most surface of the guide collar.

(1) Apply pressure to the piston through the rotatable fixture on the propeller assembly table.

(2) Force the piston to full reverse position.(3) Use hand-held protractor, as shown in Figure 7-22, to check the angle of

counterweight relative to the axis of the piston.

NOTE: The blade-to-blade counterweight angle tolerance is 1.5 degrees.

CAUTION 1: REFER TO THE APPLICABLE AIRCRAFT TYPE CERTIFICATE DATA SHEET OR HARTZELL APPLICATION GUIDE, MANUAL 159 (61-02-59) FOR THE SPECIFIC COUNTERWEIGHT ANGLE REQUIRED.

CAUTION 2: AS INDICATED IN FIGURE 7-22, THE POSITIVE ANGLE, USUALLY 2 DEGREES OR MORE, IS FOR REFERENCE ONLY. DO NOT CONSIDER IT FOR THE PRESCRIBED ANGLE.

(4) Adjust the counterweight angle, if necessary, by adding or removing one spring spacer (1450) forward of the spacer tube (item 1460 in Figure 7-15) in the feathering spring assembly to increase or decrease the angle by approximately 1 degree.

NOTE: The quantity and thickness of counterweight adjustment spacers needed at assembly will probably be the same as the quantity and thickness of the spacers removed at disassembly. If spacers are added at assembly, use the correct thickness and quantity specified for the required change in angle.

14. Setting the Reverse Angle of the Blades

A. Procedure for all models(1) Keep pressure applied to the piston through the rotatable fixture on the propeller

assembly table.(2) Keep the piston in reverse pitch position.(3) Use a bench-top protractor and special riser fixture as shown in Figure 7-24, to

set the correct reverse angle on Blade One at the reference blade radius specified in the Hartzell Propeller Application Guide, Manual 159 (61-02-59), or aircraft type certificate.

NOTE: Refer to the aircraft type certificate data sheet or Hartzell Application Guide, Manual 159 (61-02-59), for the specific reverse blade angle, blade to blade tolerance at reverse blade angle, and reference blade radius required for measurement.

(4) Use wrench TE142, as shown in Figure 7-23, to hold nut (780), and a standard 12-point socket to torque the outboard clamp bolts (770) per the Torque Values Table in the Fits and Clearances chapter of this manual.(a) While torquing the outboard clamp bolts, make sure the gasket position is

maintained in order to provide an adequate grease seal.(b) Ensure a nearly equal gap between the two halves is maintained after final

torque is applied.(5) Repeat this reverse angle setting procedure and clamp bolt torquing for each of

the other blades.

NOTE: A blade to blade tolerance is applicable when setting the reverse blade angle. A blade-to-blade tolerance is also applicable when setting the low pitch (-3 propellers) or the floating pitch (-5 and -7 propellers) and feather blade angle (all models). It is recommended that a minimum blade-to-blade tolerance be met in the reverse blade angle. This will insure the best opportunity to meet all blade angle tolerance requirements for each propeller.

(6) Confirm the correct blade angle setting and counterweight angle by cycling the propeller from reverse to feather, and back to reverse. Confirm that the reverse blade angle settings and counterweight angle are correct.

(7) If the counterweight angle is incorrect, remove and disassemble the spring. Add or remove the counterweight adjustment spacers (1450) as needed to achieve the correct counterweight angle. If necessary, reset the reverse and feather angles after adjusting the counterweight angle.



15. Checking Blade Track

A. Procedure for all models

(1) Turn the propeller on the rotatable fixture and check the height at the tip of each blade using a gage and adjustable pointer as shown in Figure 7-23.

NOTE: Blade heights at the tip should not vary more than 0.125 inch (3.18 mm).

16. Setting the Feathering Angle of Blades

A. All models except those ending in -3(AE, AEY, AF, K, KY, M, MY, N, P, PY, or Z) (1) Release the air pressure to the rotatable fixture.(2) Use a hand-held protractor to check the feathering angle on Blade One at the

reference blade radius specified in the Hartzell Propeller Application Guide, Manual 159 (61-02-59), or aircraft type certificate. See Figure 7-25.

NOTE: Refer to the applicable aircraft type certificate data sheet or Hartzell Application Guide, Manual 159 (61-02-59), for the specific requirements for feathering angle and blade-to-blade tolerance at feather blade angle.

(3) Adjust the feathering angle as necessary by removing the piston and turning the feathering stop screws (180).

NOTE 1: Before removing the piston, mark a piston ear with a grease pencil CM162, and match mark the guide collar to ensure that the piston is reinstalled in the same position.

NOTE 2: Turning a stop screw in one turn will increase the feathering angle approximately 1.5 degrees.

Turning a stop screw out one turn will reduce the feathering angle approximately 1.5 degrees.

(4) If applicable, re-safety the feathering stop screws together, two by two.

CAUTION: MAKE SURE THAT THE GREASE PENCIL MARK ON THE PISTON EAR ALIGNS WITH THE MATCH MARK ON THE GUIDE COLLAR. FAILURE TO ALIGN GREASE PENCIL MARKS MAY RESULT IN A CHANGE OF BLADE ANGLES, DUE TO NORMAL STACK-UP TOLERANCES BETWEEN THE LINK PIN HOLES AND THE LINK ARMS.

(5) Reinstall the piston. (6) Recheck the feather blade angle of all the blades.(7) Check the blade to blade tolerance at feather blade angle.

B. Models ending in -3 (AE, AEY, AF, K, KY, M, MY, N, P, PY, or Z) with External Feather Stops.(1) Release pressure to the piston.(2) Check feather angle. See Figure 7-25.(3) With the propeller in full reverse, adjust feather angle by turning all three adjusting

screws (190). Turning screws into piston will increase angle; backing screws out will decrease angle.

CAUTION: THE FLOATING PITCH ANGLE OF ALL BLADES MUST BE WITHIN A TOLERANCE OF ± 0.1 DEGREE, OR A MAXIMUM OF 0.2 DEGREE ONE DIRECTION.

(2) With the propeller assembly still mounted on the rotatable fixture of the assembly table, apply pressure to the piston until blade number one attains a floating pitch position between 20 degrees and 25 degrees.

(3) Check the floating pitch angle of each of the other blades.(4) If the blade to blade tolerance is excessive, then one or more blades must be

rotated in the blade clamp(s).(a) Use wrench TE142, as shown Figure 7-23, to hold nut (780). Use a

standard 12-point socket to loosen the outboard clamp bolts to allow rotation of the blade in the clamp.

(b) Repeat procedure 14.A. for setting the reverse angle of the blades.(c) Repeat procedure 16.A. for setting the feather angle of the blades.(d) Repeat procedure 19.A. for setting the floating pitch angle of the blades.

NOTE: Recheck the floating pitch angle after resetting any blade angle.

20. Setting the Low Pitch Angle of the Blades

A. Models ending in -2

NOTE: This model does not reverse.(1) Apply pressure, forcing the propeller into low pitch.(2) Set low pitch angle of all blades within a tolerance of ± 0.1 degree, or a

maximum of 0.2 degree in one direction.

B. Models ending in -3Setting the low pitch angle of the blades establishes "hydraulic low pitch" for the propeller.

CAUTION: WHEN A BLADE ANGLE IS SET OR CHECKED, ACTIVATE THE ASSEMBLY AWAY FROM THE REVERSE PITCH POSITION BY HAND TO RESEAT THE BLADE AND CLAMP PARTS AND TO REMOVE PLAY FROM THE ASSEMBLY.

(1) Apply pressure to the piston through rotatable fixture on propeller assembly table until Blade Number One reaches the correct low pitch blade angle as indicated by the bench-top protractor. See Figure 7-24.


ASSEMBLYPage 7-61

Rev. 17 Jun/0461-10-18

(2) Trap the pressure at this position of the setup blade.

NOTE: The low pitch angle of all blades must be within a blade to blade tolerance of ± 0.1 degree or 0.2 degree from the maximum to the minimum blade angle at low pitch.

(3) Turn the elastic pitch adjustment nuts (210) on the three propeller beta rods so that the nuts are against the bosses on the piston at low stop position.

CAUTION: ADJUSTING THE BETA RING RUNOUT WILL AFFECT THE LOW PITCH ANGLE. A RECHECK OF THE LOW PITCH BLADE ANGLE IS REQUIRED.

(4) Apply pressure to the rotatable fixture, forcing the propeller against the reverse pitch stop.

(5) Select a blade with a beta rod adjacent to it. "Zero" the dial indicator on the beta ring (420) at a place close to the selected beta rod.

(6) Adjust the other two or three elastic pitch adjustment nuts (210) to correct the beta ring (420) runout to within 0.010 inch (0.254 mm) maximum movement for one revolution of the propeller.

(7) Release pressure from the rotatable fixture, allowing the propeller blade angle to move to feather or to a blade pitch higher than low pitch.

(8) Apply pressure to the rotatable fixture to force the propeller from a higher blade angle to low pitch blade angle.

NOTE: Make sure that the elastic pitch adjustment nuts (210) are just barely engaged by the piston (50).

CAUTION: BETA RODS (320) AND BETA RING (420) SHOULD NOT MOVE WHEN VERIFYING CONTACT BETWEEN THE PISTON (50) AND THE ELASTIC PITCH ADJUSTMENT NUTS (210).

(9) Move the assembly away from the reverse pitch position by hand to reseat the blade and clamp parts, and to remove play from the assembly.

(10) Recheck the low pitch blade angle and the blade-to-blade tolerance at low pitch blade angle of the specified blades.

(11) If the blade-to-blade tolerance is excessive, then one or more blades must be rotated in the blade clamp(s).

(a) Repeat the procedure in this chapter for setting the reverse angle and tolerance of the blades.

(b) Repeat the procedure in this chapter for setting the feather angle and tolerance of the blades.



(c) Repeat the procedure in this chapter for setting the low pitch angle and tolerance of the blades.

NOTE: If the blade-to-blade tolerance is within specification, but the actual blade angle is not within specification, evenly turn the elastic pitch adjustment nuts (210) down to increase the low pitch angle, or turn them up to decrease the low pitch angle.

(12) With pressure applied to the piston, and with the propeller assembly in full reverse position, check the beta ring runout. Total maximum allowable runout is 0.010 inch (0.25 mm).

SPECIAL TOOLS, FIXTURES, AND EQUIPMENTPage 9-3

Rev. 11 Oct/0161-10-18

1. Minimum Facility and Tooling Requirements

A. Tooling

Propeller repair stations approved to overhaul Hartzell propellers are expected to possess precision fixtures, tools, and blade tables for blade inspection and rework. Except as specifically required in this manual, locally fabricated tooling is acceptable for most repair and inspection operations.

B. Facilities

(1) Grinding, plating, and painting of propeller components have the potential for health and safety hazards beyond that of other areas of a typical workshop. It is expected that such areas be in compliance with industry standards and governmental regulations concerning occupational safety and health, as well as environmental protection.

(2) Workshop areas need to be segregated to prevent contamination. Separate areas should be designated for cleaning, inspection, painting, plating, and assembly. Propeller balancing must be performed in a draft-free area.

2. Special Tools

NOTE: It is the responsibility of the repair station to determine the special tooling required for the propeller they are servicing or overhauling. The applicable overhaul manual and the numerical index of Hartzell Manual 165A (61-00-65) provide necessary information. Hartzell maintains no exact list of tools required for specific models of propellers or levels of service.

A. Special Tools

Hartzell Tool and Equipment Manual 165A (61-00-65) contains a listing of special tools available from Hartzell. The manual also includes vendor lists for other specialty tooling not sold by Hartzell.

B. Listings

The Introduction section of Manual 165A (61-00-65) provides information about what is included in the listings and how to quickly locate tools.
