Bringing your Gehl R105 skid-steer loader back to factory numbers is the job the 202 pages of this Gehl R105 service manual PDF (Form No. 50950298) are written for, and they cover the same machine under its twin badge, the Mustang 1050R. Each badge gets its own hydrostatic/hydraulic schematic, and the electrical schematics cover both DPF and non-DPF wiring, including the ROPS/FOPS circuits. The hydrostatic, hydraulic, electrical and engine chapters each have a troubleshooting guide, and the engine section ends with Yanmar diagnostic trouble codes and DPF regeneration procedures. With a filter change, refill the crankcase with 7.6 US qts. (7,2 L), and torque the hydrostatic pump to flywheel housing cover screws to 80 ft-lbs (112 N·m). A made-up torque on that joint is how a pump flange cracks. The PDF is bookmarked by chapter and has a text layer, and its exploded component views let you identify the exact piece before you call the dealer, so you order the right part the first time.
