This is the factory service manual for the Mustang ML 48T all-wheel-steer loader, part number 918139, dated 2005, covering 208 pages of service and troubleshooting for the machine and its Deutz F4M 2011 engine.
Sections run through machine operation, the engine, the hydrostatic power train, the front and rear axles, the brake and steering circuits, the work hydraulic system, the electrical system, and a dedicated torque specification chapter. Reference data includes the 59 DIN hp rating at 2400 rpm, the 295 lb.-ft. wheel nut torque, the 4931 psi (340 bar) variable pump pressure, and the 3046 psi (210 bar) work hydraulics pressure.
Owners and mechanics can use it to diagnose weak hydraulics, steering and brake faults, and engine power loss, then set fasteners and pressures to factory values. The PDF is searchable and bookmarked, so you can find a procedure fast and print only the pages you need in the shop.
