Part of the Case Repair Manuals.
This 806-page Case 821E Service Manual PDF (OEM #87551879A) puts the whole Wheel Loader on your bench: engine, fuel system, electrical, steering, power train, brakes, hydraulics, and mounted equipment. Inside: fold-out electrical and hydraulic schematics, a full troubleshooting section for transmission and brake pressure checks, and page after page of removal and installation procedures. You also get error code listings, stall test steps, and factory torque tables for every fitting size on the machine. Torque the 3/4-inch O-ring face seal fittings to 90 to 110 N-m, then drain the engine oil into a 14.2-liter container before you pull the pan. Your loader is down and every hour costs money. Get the factory numbers, not forum guesses. This bookmarked PDF opens on any device; search any spec by keyword and get back to wrenching.
