Part of the Case Repair Manuals.
Looking for a Case 880R service manual PDF you can trust? This 771-page factory service manual (OEM #9-67074) walks you through the entire 880R excavator, from engine tune-up to the swing gearbox and outriggers. Inside: wiring harness diagrams, hydraulic schematics for the pump, control valves, swivel, and swing motor, and a full troubleshooting section for engine diagnosis. You also get step-by-step rebuild procedures for the torque converter, drop box transmission, axle planetaries, and the air brake system, right down to the compressor and brake valve. Replace the fuel filters every 500 hours, and torque the pump housing retaining bolts to 35 to 42 ft. lbs. Your machine is down; forum guesses will not restart it. Bookmarked for quick section jumps: download it, load your tablet, and take the factory numbers straight to the machine.
