Hydrostatic pump removal, travel drive motors and track tension cylinders lead off this Gehl RT105 service manual PDF, a 353-page factory book (Form No. 50950457) for the compact track loader that also covers the engine, lift arm, cab and CAN controls. Gehl also sells this machine as the Mustang 1050RT, and the book covers it under both names. Chassis and ROPS/FOPS electrical schematics sit beside separate DPF and non-DPF harness diagrams, plus a hydrostatic/hydraulic schematic tracing oil from the gear pump through the control valve to the lift and tilt cylinders. Diagnosis gets real room too: engine error codes, CAN troubleshooting and indicator lamp charts. Fill the hydraulic system with 30.0 L (8 U.S. gallons), and condemn the lift cylinder seals if retraction passes 19 mm (0.75 in) in 15 minutes. Chasing a drifting bucket eats your whole day. The PDF is bookmarked and text-searchable, so it takes you from the drift test to a loader holding its load again.
