Working on a 5625, 5625SX, or 5625DX and need factory numbers instead of guesswork? This 296-page Gehl 5625 shop manual PDF (OEM #907245) carries the full rebuild data for all three variants: chassis, T-bar controls, hydrostatic and hydraulic systems, electrical, and engine. The hydraulic schematics are variant-matched to the SX and DX, the wiring harness diagrams come with a circuit/function chart, and troubleshooting guides run across four major systems. Roughly 50 pages cover exploded views; another 200 walk through step-by-step procedures for tandem pump removal, planetary gearcase disassembly, lift/tilt cylinder rebuild, and QGS control module diagnostics. Torque the axle nuts to 120 lb-ft (163 Nm); hold hydrostatic charge pressure between 120-150 PSI on the DX. With the machine down, download it, open it on a tablet, and jump straight to the bookmarked section you need.

Gehl 5625, 5625SX, 5625DX Common Problems This Manual Covers
Gehl 5625 hydraulic system losing pressure, weak lift or tilt response, and bucket drift p. 196
Test the control valve relief pressure using the steps on page 196; a healthy reading sits between 2350 and 2500 PSI. Low pressure points to the relief valve cartridges, so pull and inspect them. Swap any that are worn and torque the replacements to 70 lb-ft (88 Nm) per page 237.
Manual Section: Relief Pressure Test, Control ValveEngine turns over but will not start during cold weather or exhibits long cranking times p. 245
Inspect the glow plugs and their wiring for corrosion, then measure each plug's resistance per page 245. A good plug reads about 13 ohms on the multimeter. Anything outside that range means the plug is bad; replace it to get cold starts back.
Manual Section: Glow Plug TestHydraulic oil leaking from steering cylinders or tilt cylinders experiencing excessive drift under heavy load p. 198
Run the tilt cylinder test on page 198 to gauge internal leakage. Drift should stay under the .38" (10 mm.) in 15 minutes limit. If a cylinder bleeds past that, rebuild it and torque the cylinder rod lock nut to 350 lb-ft (474 Nm) per page 219.
Manual Section: Tilt Cylinder TestDrive system feels sluggish or jerky and wheel hubs exhibit excessive play during operation p. 63
Check drive chain tension inside the chaincases by measuring deflection as detailed on page 63. Bring the tensioner to .25" @ 20 lbs. (6.35cm @ 9kg). With that set, inspect the wheel bearings and torque the axle nuts to 120 lb-ft (163Nm) on page 67.
Manual Section: DriveFrequently Asked Questions
How do I reset the hydraulic pressure on a Gehl 5625?
Hydraulic pressure on the 5625 is set at the Control Valve adjuster screw. Turn the screw IN to raise pressure and OUT to lower it. The reading should land at a minimum of 2350 PSI and no higher than 2500 PSI.
How do I reset the safety interlock on a Gehl 5625SX?
There's no manual reset button here. Operation resumes once the operator is seated, the Restraint Bar is down, and the Key Switch is in the "ON" position. The interlock simply blocks the machine until all three conditions are met.
What are the torque specs for Gehl 5625 loader arms?
No single "loader arm" torque figure exists. Instead, the manual lists general specs by bolt size and grade (Grade 5, 8, 10.9) for both Unified National Thread and Metric Course Thread fasteners. For loader arm hardware, work from those general torque tables on page 294.
How to reset Gehl 5625SX controller
No dedicated controller reset is documented for the 5625SX. The QGS Control Module works by cycling the Key Switch "ON" and "OFF" to run the glow plugs, but the manual details no separate reset step.
What format is this Gehl 5625, 5625SX, 5625DX manual in?
Immediate download of the full 296-page searchable Shop Manual. Open it on any device, whether that's a laptop at your desk or a phone in the field.
Can I print specific sections of this Gehl 5625, 5625SX, 5625DX Shop Manual?
Yes. Print as many copies as you want; there are no restrictions. Plenty of mechanics print just the section they need and carry it to the shop floor.
Are there hydraulic schematics in this Gehl 5625, 5625SX, 5625DX manual?
Full hydraulic system diagrams are included, covering circuits, valve locations, and component specs for the Gehl 5625, 5625SX, and 5625DX.
Document Quality
This document is a scanned PDF, meaning you can search the full text, but you cannot copy and paste directly. The text quality is generally crisp and easy to read throughout the manual. Diagrams and illustrations are primarily raster images (photos or scanned drawings), with labels that are mostly readable, though some smaller text on diagrams may require zooming. Page condition is good overall, with minimal scan artifacts, stains, or skewed pages. There are numerous blank pages marked "Notes" or "This page intentionally left blank" scattered throughout the document, particularly at the end of sections.
