Section 10 – General

This opening section establishes the foundation for everything that follows. It includes complete machine specifications for both the JD570 and JD570A, including travel speeds, turning radius, blade range, and tire pressure data. The predelivery and after-sale service procedures walk through the checks a dealer or owner should complete before the machine goes to work — battery, coolant, fuel system, air cleaner, crankcase oil, tandem drives, and circle drive gearbox. You will also find the tune-up and adjustment procedures, the lubrication chart with capacities and recommended lubricants, and the separation procedures for splitting the power unit from the frame, removing the engine, separating the clutch housing, and removing tandems. The section closes with torque values and special tools.

Section 20 – Engine

The engine section begins with a diagnostic guide for common malfunctions — hard starting, lack of power, black or gray exhaust smoke, low oil pressure, erratic speed, and abnormal noise. From there it moves into the basic engine: cylinder head, valves, rocker arms, valve tappet clearance adjustment, cylinder block, liners, pistons, rods, crankshaft, main bearings, flywheel, timing gear train, and camshaft. Detailed specifications and torque values are provided throughout, along with tune-up data and the engine break-in procedure. The engine lubrication group covers the oil pump, oil filter, checking engine oil pressure, and diagnosing lubrication system problems. The speed control linkage group explains fast idle, slow idle, and linkage adjustment for the different injection pump models. The cooling system group covers the radiator, crankcase oil cooler, water pump, and related repairs.

Section 30 – Fuel System

Fuel system diagnostics are covered first, with a guide to isolating problems in the fuel tank, filters, transfer pump, air intake system, and injection pump. The fuel tank, filters, and transfer pump group covers both A.C. and Airtex pumps used on early and later units. The air intake system group includes the air cleaner, turbocharger, and the tests and repairs associated with each. The fuel injection pump group covers the Roosa Master Model C, Model CB, and Model JDB pumps, including removal, repair, installation, timing, bleeding, and cam advance adjustment. Injection nozzle service is referenced to SM-2045. Specifications and special tools round out the section.

Section 40 – Electrical System

The electrical section opens with wiring diagrams and descriptions for the 12-volt, negative-ground system. It covers the charging system for two engine serial number ranges (before and after 130705), including alternator and regulator diagnosis, testing, and repair. The starting motor group covers both Delco Remy and John Deere starting motors, with diagnosis, testing, repair, assembly, and installation procedures. Miscellaneous components include the windshield wiper motor and hour meter. Wiring color codes and connector replacement procedures are included.

Section 50 – Power Train

The power train section is the largest in the manual. It begins with the engine disconnect clutch — removal, repair, installation, and adjustment. The transfer drive group covers the input, idler, and output gear assemblies, including disassembly, inspection, and installation with end play adjustment. The Power Shift transmission group is extensive: testing procedures, malfunction diagnosis, clutch valve, oil pressure regulating valve, transmission control valve assembly, transmission case and covers, clutch housing, clutch pack and oil manifold, planetary pack, planetary carrier, reduction gear train, tow disconnect, speed and direction selector linkage, clutch pedal valve linkage, and oil filter and pump intake. The differential group covers the differential, differential drive shaft, differential control valve, and the associated adjustments. The final drive system group covers the tandem drive, tandem pivot assembly, and final drive removal, repair, and installation. The section closes with specifications and special tools.

Section 60 – Power Steering and Brakes

This section covers the power steering valve for both the JD570/JD570A and the serial number ranges that used different valve designs. Diagnosis, repair, assembly, adjustment, installation, and bleeding procedures are all included. The brake valve group covers general information, diagnosis, and repair. The brake cylinders and disks group covers the wet-disk brake system, including bleeding procedures. The parking brake group covers the dry shoe expanding type brake, including diagnosis, repair, adjustment, and bearing and shaft replacement.

Section 70 – Hydraulic System

The hydraulic system section covers the closed-center, constant-pressure system used on these graders. It begins with component descriptions and system tests, then moves into filters, valves, and the accumulator. The main hydraulic pump is covered with reference to component technical manual CTM-7 for complete repair information, plus pump drive and engine support details. The function control valves group covers the nine double-acting valve assemblies, including lockouts, orifice plates, and installation. Hydraulic cylinders are covered with testing and repair procedures. The circle drive hydraulic motor group covers the motor and rotary manifold. The saddle valve and retaining pins group covers the saddle locking valve and locking pin assembly. Specifications and special tools complete the section.

Section 80 – Miscellaneous

The final section covers the circle drive gearbox, including removal, repair, and installation. It then moves into the drawbar, circle, and moldboard group, with circle adjustment procedures and moldboard extension installation. The saddle, main frame, front axle, scarifier, and engine frame group covers the structural components and their repair. Specifications and special tools close out the manual.

What This Manual Enables You to Do

With this John Deere JD570 JD570A Technical Manual in hand, you can confidently tackle the jobs that keep a motor grader earning. Adjust valve tappet clearance to the specified 0.014-inch intake and 0.018-inch exhaust settings. Diagnose a Power Shift transmission that shifts too slow or slips. Rebuild the hydraulic pump or replace the accumulator. Service the wet-disk brakes or adjust the parking brake. Repair the circle drive gearbox or the tandem drive. Trace an electrical fault using the wiring diagrams. Torque every critical fastener to the values John Deere specifies — from the 95 lb-ft cylinder head cap screws to the 300 lb-ft wheel retaining cap screws.

Every procedure in this JD570A repair manual was written for the experienced service technician. The specifications are real — the kind you cannot guess at. The torque values are exact. The diagnostic guides save hours of trial-and-error. For a machine like the JD570 or JD570A, getting the details right is the difference between a repair that lasts and one that comes back.
