This is the OEM source for the SL7810E Skid-Steer Loader: 238 pages of Gehl factory documentation (Form #917228), running from mainframe and chaincase drives through load-sense hydraulics and electrical systems. You'll find hydraulic schematics for both T-Bar and Joystick configurations, full electrical wiring diagrams, a hydrostatic troubleshooting guide, and 48 pages of exploded-view assemblies covering every major component. The troubleshooting sections work through the hydrostatic system, hydraulic circuits, and electrical faults, each with step-by-step cause-and-remedy tables. Torque figures are here as well: wheel nuts at 240 ft-lbs (325 N•m), tilt cylinder pivot pin capscrews at 80 ft-lbs (108 N•m). Stop cross-referencing dead forum threads for numbers that may not match your machine. Everything is bookmarked by section and keyword-searchable, so you can open it on your phone at the loader and get the job done.

Gehl SL7810E Common Problems This Manual Covers
Gehl SL7810E engine loses power after filter changes and turns over but won't start. p. 174
Bleed water from the fuel filter and tank per page 174, then drain the water separator and add fuel conditioner. Restart and confirm the engine holds its standard idle of 1000±50 RPM, the figure given on page 107.
Manual Section: Engine Troubleshooting GuideLift arm fails to raise or lower when operating the standard controls under normal load. p. 124
Inspect the lift solenoid valve wiring for breaks. With the connections intact, swap the solenoid as noted on page 124. Test the lift cylinders, checking that the lift and tilt cylinder rod assembly locknuts hold 350 ft-lbs (474 N•m).
Manual Section: Hydraulic System Troubleshooting GuideHeavy fluid leaks around the lift or tilt cylinders, with sluggish hydraulic action overall. p. 136
Pull the leaking cylinder and fit a new seal kit per page 136. Snug all hydraulic fittings without overtightening them, referencing page 40. Verify the machine holds a steady 3300 psi (228 bar).
Manual Section: Hydraulic System Troubleshooting GuideHigh-flow auxiliary hydraulics fail to function with the operator restraint bar fully lowered. p. 125
Check the spool lock solenoid connections as directed on page 125. Repair any damaged wires or replace the faulty switch. Run the system and confirm it reaches 3300 psi (228 bar).
Manual Section: Hydraulic System Troubleshooting GuideFrequently Asked Questions
What are the torque specs for the GEHL SL7810E wheel bolts?
Torque the wheel nuts to 240 ft-lbs (325 N•m). The manual gives this figure in the Drive Chain Adjustment procedure, at the step where you reinstall the tires.
What are the replacement specifications for Hydraulic cylinder seals?
Install a new seal kit whenever a cylinder shows external leakage. The manual says to change seals as needed and points you to the lift or tilt cylinder exploded views for reassembly order, which call out one seal kit per cylinder.
What are the replacement specifications for Hydraulic hoses and fittings?
Hoses are listed by pressure rating, including HOSE/6000 PSI and HOSE/MEDIUM PRESSURE. Fittings are called out by type, such as FITTING/STRAIGHT and FITTING/90°, for the various points in the hydrostatic and hydraulic systems.
