Looking for the Case 721E service manual PDF straight from the factory? This 817-page Case 721E Wheel Loader Service Manual (OEM #87551874A) covers the whole machine: engine, power train, steering, brakes, hydraulics, and mounted equipment. You get full wiring diagrams for chasing electrical gremlins through your loader, hydraulic schematics with pressure check procedures, and troubleshooting charts for the transmission, brakes, and ride control system. Inside: stall tests, error codes, and step-by-step removal and installation for every major component, from the center pivot to the cab glass. Torque the engine mounting bolts to 244 to 298 Nm, then refill with 14.2 liters of oil after a filter change. No more chasing wiring faults with a multimeter and a prayer. Bookmarked and keyword-searchable; pull it up on your phone, walk out to the loader, and start wrenching.
