Part of the John Deere Repair Manuals.
This is the John Deere 310G Backhoe Loader repair technical manual, TM1886, a 780 page factory service reference for the machine and its POWERTECH 4.5L and 6.8L diesel engines.
It walks through removal, repair, and installation across the full machine: wheels, axles and MFWD suspension, the power shift transmission and torque converter, engine and auxiliary systems, steering, service brakes, electrical systems, the operator's cab, the main hydraulic system, and both the loader and backhoe. Weights, clearances, and torque values are listed at the start of each group.
This volume is the repair half of the set, so base engine internals are covered separately in CTM104. For the 310G owner or shop rebuilding hydraulics, driveline, or structure, it gives the exact procedures and specifications the factory intends.
