Case 880R Excavator Service Manual

What's Covered in This Manual

This is the factory service manual for the Case 880R wheeled excavator, built around the Case 336BD four-cylinder turbocharged diesel engine. It's wheel-mounted rather than a crawler, so alongside the usual engine and hydraulic sections you also get full coverage of the axle differential, planetaries, drive shafts, steering linkage and wheel brakes.

The book runs by series and section number, starting with general engine specifications and torque charts and working through engine, fuel system, hydraulics, steering, power train, brakes, electrical, and mounted equipment (booms, outriggers, swing gearbox, cab heater), with diagnosis and reassembly spelled out step by step.

Worth knowing: Case split the axle differential, axle planetaries, and brake shoe/wheel cylinder sections into two separate procedures by serial-number range (6202128 thru 6202226, or 6202227 and after). Check your machine's serial plate, on the side of the engine above the cranking motor, before starting.

Good to Know

The front cover of this scan carries a stray "1150L Crawler Dozer" label left over from the binder it was copied from - every section inside is clearly headed "880R Excavator," confirming this is the wheeled excavator manual, not a dozer book.
