Part of the John Deere Repair Manuals.
This is the complete John Deere factory technical manual (TM1228) for the 544C Wheel Loader. Across 1,389 pages it covers every major system on this machine: disassembling and rebuilding the turbocharged 414 cu. in. diesel engine, servicing the Power Shift planetary transmission and twin-turbine torque converter, repairing the front and rear axles, and tracing the full electrical system with wiring harness information. It also covers the main hydraulic system, loader linkage, and backhoe attachment service. The same document a John Deere dealer technician works from, with tightening torques, fluid capacities and test pressures listed so the work is done to factory spec.
