Looking for the Case 880C service manual PDF your dealer worked from? All 783 pages of this factory Service Manual (OEM #9-69762) cover the 880C excavator, from the 504BD engine down to the turntable bearing. You get wiring harness diagrams, equipment hydraulic schematics with diagnostic tests and checks, and troubleshooting charts for the drive motor circuit, swing motor, and track system. Inside: engine tune-up and rebuild procedures, fuel injection pump service, final drive transmission teardowns, plus hoist, crowd, and tool cylinder hydraulics. Set track sag between 1/2 and 1-1/2 inches, and torque those cylinder head bolts to 200 to 210 ft. lbs. on reassembly. No more chasing hydraulic faults on a 40-year-old machine with forum guesses. Bookmarked with a full text layer; type the spec you need, jump straight to it, and get back on the sticks.
