Part of the Kubota Repair Manuals.
This is the Kubota KC70 workshop manual for the tracked dumper, publication 97899-61870, a 26 page factory service document covering the machine's mechanism and servicing procedures. It details the transmission and power train, the dumping hydraulic system, the V-belt drive, and the full wiring diagram with cord color legend and fuse ratings.
The servicing section gives tightening torque tables for standard and special bolts, transmission and hydraulic oil types and capacities, cautions for disassembly and reassembly, and adjustment procedures for the main clutch, parking brake, steering levers, belt tension, and crawler tracks.
A wear parts replacement guide and a troubleshooting and countermeasures section round it out, walking you through no drive, continuous turning, and engine stall symptoms. Use it to service, adjust, and repair the KC70 to factory specification.
