Gehl SL4510 GASOLINE, SL4610 DIESEL Common Problems This Manual Covers
Engine cranks but will not start or stalls
Owners often chase a unit that cranks but will not fire, or that starts and then stalls under load. The Engines section covers both the Ford 98 CID gasoline and Perkins 4.108 diesel, including fuel delivery and troubleshooting where these no start faults usually trace.
Manual Section: Engines p. 82Weak or slow lift and tilt hydraulics
Slow or weak lift and tilt is a common complaint, often from low fluid, a clogged filter, or a leak. The Hydraulics System section includes component testing, the tilt and lift cylinders, the gear pump, and the oil filter so you can isolate the cause.
Manual Section: Hydraulics System p. 59Sluggish or unresponsive drive
A drive that feels weak or does not respond evenly points to the hydrostatic circuit. The Hydrostatic System section walks through neutral, forward, reverse, and turns along with troubleshooting to find the fault.
Manual Section: Hydrostatic System p. 37Disc brakes out of adjustment
Skid loader disc brakes drift out of adjustment and wear with use. The Drive section gives disc brake adjustment and replacement procedures split by serial number, plus brake cable service.
Manual Section: Drive p. 22Intermittent controls or electrical faults
Controls that respond intermittently usually trace to wiring, a safety switch, or a control circuit fault. The Electrical System Troubleshooting section includes the SL4510 and SL4610 system diagrams to trace the circuit.
Manual Section: Electrical System Troubleshooting p. 78Hard cold starts on the diesel
The SL4610 diesel can be hard to start in cold weather, often from glow plug, battery, or fuel delivery issues. The Engines section covers the diesel powered engine and its troubleshooting.
Manual Section: Engines p. 82Frequently Asked Questions
