John Deere 870G, 870GP, 872G and 872GP Motor Grader Repair Manual (TM13070X19)

Machines covered

This manual (TM13070X19, dated 09MAR17, with earlier editions back to 2014) covers four motor grader variants - 870G, 870GP, 872G and 872GP - within the PIN range 1DW870G___C656729 through 1DW872GP___D678817. All run John Deere's PowerTech 9.0L diesel engine and a DF230 Series transmission.

What this manual covers

Deep engine and fuel-system repair is kept in separate component manuals - the PowerTech 9.0L base engine manual (CTM400) and the Level 14 electronic fuel system manual (CTM385) - so this book focuses on what's specific to the grader itself: removal and installation of the engine, the DF230 transmission's hydraulic system, axles, the torsional isolator, steering, brakes, the grading device's circle gearbox and frames, and a dedicated ground conditioning tool section.
