Gehl 5635SX & variants Common Problems This Manual Covers
Sudden complete loss of hydraulic drive, machine won't move or respond to controls p. 107
Inspect the engine-to-pump coupling before pulling the hydrostatic pump. Remove the engine access cover and check the coupling hub clearance; the gap between the housing assembly and hub must be 3/16" (2mm) per page 107. If the coupler is cracked, worn, or out of spec, replace it before any further hydraulic diagnosis.
Manual Section: Hydrostatic SystemEngine bogs hard under load, thick white smoke from exhaust, near stall p. 165
Pull and inspect the air filter element. A clogged element starves the engine and causes white smoke under load. Next, check fuel lines and filters for restrictions. Verify the engine oil level meets the 10.5 quart (10 liter) crankcase capacity. Follow the engine troubleshooting guide on page 165 if those checks come up clean.
Manual Section: EngineTraction drive sluggish or won't operate, one or both sides won't respond p. 97
Confirm the parking brake is fully released, then check the hydrostatic oil level in the reservoir. Follow the troubleshooting guide on page 97, which covers traction drive failures, drive wheels not turning, and a neutral position that is difficult to maintain. If both sides are weak, run the charge pressure test procedure on page 104 to pinpoint pump relief valve issues.
Manual Section: Hydrostatic SystemLift arm raises slowly or won't hold raised position, bucket drifts down p. 112
Check hydraulic oil level first; the reservoir holds 16 gallons (60.5 liters) and low oil is the most common cause of sluggish lift. Follow the hydraulic system troubleshooting guide at page 112, which covers slow cylinder action and lift arm that won't raise a heavy load. Inspect all hose connections for leaks before running pressure tests.

Document Quality
This is a scanned PDF document, not a native digital file. You can search and copy the full text, as an OCR layer has been applied, and the text is generally crisp and easy to read throughout. The document contains a mix of clear line diagrams and rasterized photographs, with all labels on illustrations being readable. Pages are mostly clean with minor scan artifacts like slight skew and occasional darker edges, but no significant stains or marks obscure content. Be aware there are several intentionally blank 'NOTES' pages interspersed within the manual.
