Altogether this repair technical manual walks through the major systems of the 670G, 670GP, 672G and 672GP graders — engine removal, transmission, powered axles, hydraulics, brakes, steering, frame and articulation, operator station, and the complete grading device including circle gearbox and hydraulics. It also contains the dealer fabricated tool drawings that are often needed for the more involved component repairs.

What This Manual Enables You To Do

With the John Deere 670G 670GP 672G 672GP repair technical manual on hand you can confidently remove and reinstall the engine, tear down and rebuild a powered front axle, service the 6WD pump and motor, replace articulation bearings, overhaul the circle drive gearbox, bleed the service brakes, adjust the circle clearance, replace grader control valve sections and much more. Every group opens with a summary of the tools, materials, parts kits, specifications, wear tolerances and torque values required, so you are not guessing when a fastener or a clearance matters.

Correct procedures and specifications matter on a machine this size — a wrong torque on an axle housing cap screw, an incorrectly shimmed articulation bearing, or a misadjusted circle can cost far more than the manual itself. Using the factory repair procedures keeps your grader running properly and avoids damage that comes from working blind.
