Part of the Case Repair Manuals.
This 678-page Case Corporation 880B Excavator Service Manual (OEM #9-68144) covers the 336BD and 336BDT engines that power the 880 Excavator line, from cylinder sleeves and crankshaft journals down to the fuel injection pump. Open it up and you get wiring harness diagrams for the electrical system, hydraulic schematics for the equipment pump circuits, and a full troubleshooting section covering track, power train, and brake system faults. You also get torque charts and maintenance interval tables that walk you through fuel filter changes and cleaning procedures without guesswork. Set the No. 1 hydraulic pump section output at 42 gpm (168 L/min), and dial the main relief valve to 2650 psi (18,270 kPa) before you close it back up. Stop chasing hydraulic gremlins with a pressure gauge and a hunch; this manual gives you the exact numbers. Bookmarked and searchable, so you jump straight to the boom, swing motor, or engine section without flipping pages.
