INTRODUCTION

This technical manual for the JD570 Motor Grader is a concisely written publication for the journeyman" mechanic. It contains procedures and specifications which an individual cannot be expected to remember.

Use the table of contents at the front of the manual to locate the generalized section and group that you are seeking. Use the table of contents on the first page of the section to locate the specific information desired.

Coverage for each component includes general information, diagnosis and test, removal when necessary, adjustments, installation when nec-essary, specifications, and special tools. For your convenience, the specifications and special tools will always be listed at the end of each group.

Use the lubrication chart in the General Sec-tion to determine what type and amount of lubri-cant to use after servicing a component or sys-tem.

Use the tune-up chart in the General Section as a check list in tuning up a machine. The re-quired specifications are included in the chart.

Some components such as the fuel injection pump and the alternator are identified by model

Engine and Transmission Serial Numbers

numbers. Use these numbers when ordering re-placement parts for these components.

The engine is identified by a serial number plate on the R.H. side. Use this number when or-dering replacement parts for the engine.

The transmission is identified by a serial number plate on the R.H. side of the case. Use this number when ordering replacement parts for the transmission.

Use the motor grader serial number, on the R.H. side of the main frame, to identify all other replacement parts.

NOTE: Be sure to use all of the digits in the model number or serial number when ordering replacement parts.

You will notice that no effort has been made to explain theory of operation in this manual un-less a component is peculiar only to this machine. If you wish to review basic prinCiples, we highly recommend the John Deere "Fundamentals of Service" manuals for this purpose.

This technical manual was written for you-the serviceman. Keep it readily accessible and refer to it whenever in doubt about correct maintenance procedures.

General Lubrication


LUBRICANTS

Effective use of lubricating oils and greases is perhaps the most important step toward low upkeep cost, long life, and satisfactory service for your customer. Only those lubricants spec-ified should be used

ENGINE LUBRICATING OILS

Three factors should be considered when se-lecting proper oil for the engine crankcase: the reliability of the oil supplier and manufacturer, the viscosity for the fill period, and the type of service under which the engine will be operated Consider each of these.

Reliability of Oil Supplier and Manufacturer There is no universal label indicating the

quality of an oil, nor is there an independent re-viewing organization to insure that claims made on oil labels are true. Therefore it is important that only recognized brands of oils, furnished by a reliable manufacturer and supplier, are used in the grader.

Viscosity Either single viscosity oil or multi-viscosity

oil may be used. Single viscosity oil provides satisfactory lubrication when smaller or more limited temperature fluctuations are encoun-tered. Multi-viscosity oil provides satisfactory lubrication whenever a wider range of tempera-ture is encountered It also makes starting easier at low temperature.

Depending on the highest expected prevailing temperature for the fill period, advise your cus-tomer to choose oil of viscosity shown in the following chart:

Single Multi-Air Temperature Viscosity Oil Viscosity Oil

Above 90°F. SAE 30 SAE 20W-40 32°F. to 90°F. SAE 20W SAE 10W-30 _10° F. to 32° F. SAE lOW SAE 10W-30 Below -10°F. SAE 5W* SAE 5W-20*

*Use of SAE 5W or 5W-20 oil may cause some increase in oil consumption. Check oil level more often when using this oil.

The oil manufacturer identifies, on the oil container, the type of service for which an oil is classified The identification is an American Petroleum Institute (API) service designation.

Litho in U.S.A.

The manufacturer may also indicate on the con-tainer that the oil meets an Ordnance Depart-ment military specification or other engine manufacturer's requirements.

API service classifications are not specifica-tions and do not necessarily guarantee quality. These classifications only establish terminology or type of service so that the oil manufacturer may make his best recommendations. Military designations identify oils which have qualified under military performance specifications.

Type of Service The type of service under which your custom-

er's engine is operated is determined by the amount of sulfur in the fuel being used. When fuel contains less than O. 5% sulfur, he should use an oil meeting military specification, Mil-L-2104B. Where Mil-L-2104B oil is not immediate-ly available, Supplement 1 or API service DM oil may be used. When fuel contains more than 0.5% sulfur, oil meeting specification Mil-L-45199A, classification Series 3 (S-3), or API service DS should be used. As further assurance of quality, only those oils bearing the following statement on the container or words to the effect, "Passes Car Manufacturers' MS Sequence Tests," should be used.

TRANSMISSION-HYDRAULIC OILS

Use only John Deere Type 303 Special-Pur-pose Oil or its equivalent in the transmission-hydraulic system. other types of oil will not give satisfactory service and may cause damage. This oil may be used in all weather conditions.

GREASES

SAE mUltipurpose-type grease is recom-mended for all grease fittings. Wheel bearing grease is recommended for front wheel bearings. Grease should be carefully applied to provide necessary lubrication and keep contamination out of bearings.

STORING LUBRICANTS

The grader can operate at top efficiency only if clean lubricants are used. Store lubricants in clean containers in an area protected from dust, moisture, and other contamination.


Grader, Motor - JD570 TM-IOOl (Nov-67)

SEPARATING POWER UNIT FROM FRAME

The power unit must be separated from the frame to service the final drives, transmission or differential. If shop facilities are limited, it is advisable also to make this separation for engine removal.

NOTE: Once separation is made, the power unit can only be moved in a straight line. There-fore, be sure motor grader is positioned cor-rectly before making separation.

Use the following procedure to separate the power unit from the engine frame.

Remove muffler, air cleaner, hood, grille, and fuel tank.

Unhook wiring harness. Tag all connectors and terminals.

Break hydraulic connections at clamp and disconnect all cables.

Remove the split baffle from under radiator.

Fig. I-Support Bar

Install support bar under tandem steps as shown in Fig. 1. See "Making Special Tools" in this group for construction details of support bar.

C AUT ION: The support bar prevents the transmission and engine from oscillating around the final drives once the connecting pins are re-moved. Be sure support bar Is snug against clutch housing.

SEPARATION Remove rear bumper and rear frame.

Attach hoist to main frame.

Fig. 2-Pin Plates

Remove the cap screws and retaining pin plates (Fig. 2) from the connecting pins holding the engine frame to the final drives. Install grease fitting in each pin and use grease gun to remove pins. Remove the grease fittings before reinstalling the pins.

Fig. 3-Power Unit Separated from Frame

Use hoist to lift main frame. Roll power unit out from under the engine frame (Fig. 3).
