GEHL 6625 Service Manual – What You Get from a Factory Print

I’ve torn down more skid steer loaders than I care to count. The GEHL 6625 Service Manual is the one I reach for when a 6625 comes into the shop with a fuel leak or a hydraulic whine. It’s 76 pages of factory drawings, not some aftermarket artist’s impression. Page 2 already tells you how to locate the serial number – right chassis riser between the lift arm and lift cylinder. That’s the kind of detail you need when the customer is waiting and the part number is rubbed off.

7 Systems Covered – From Fuel Tank to Hydrostatic Drive

This manual breaks down the machine section by section. You get the Chassis, Fuel Tank, Grill & Access Covers (pages 6-7), then Axles, Drive Train & Related Components (8-9). The Engine & Related Components section (14-15) covers the powerplant – and yes, the Fuel system is in there with all the lines, filter, and tank details. Need to pull the hydrostatic drive? Pages 22-23 show the Tandem Hydrostatic Pump and Drive Motor. Every bolt has a part number and reference to the hydraulic diagram later in the book.

Does This Manual Cover the Engine and Fuel System?

Yes. The Engine section (pages 14-15) includes the air cleaner, muffler, and radiator on 16-17, but the Fuel tank is part of the chassis group on pages 6-7. For fuel system components – lines, fittings, tank mountings – you’ll find them there. Later in the Accessories section (pages 47-57), the GEHL 6625 Service Manual also covers the Air Purifier Kit if you’re dealing with a fuel contamination issue. Nothing is left to interpretation: each part is illustrated with a callout number that matches the parts list.

Hydraulic Components: What the Factory Manual Shows

Pages 37-46 are the heart of the hydraulic section. You get exploded views of the Lift Cylinder (page 37), Tilt Cylinder (page 37), Grapple Cylinder (page 38), Planetary Gearcase (page 39), Drive Motor (page 39), Tandem Hydrostatic Pump (pages 40-41), Single Gear Pump Rexroth (page 42), Dual Gear Pump Rexroth (page 43), Main Control Valve (page 44) with its Differential Relief Valve, Self-leveling Valves (page 45), and Solenoid Valve (page 46). If you’re swapping a pump or resealing a cylinder, you need the factory torque sequence – the manual won’t leave you guessing. Torque values are listed in FT-LB and INCH-LB in the abbreviation table on page 2.

Source Validity – Why Aftermarket Manuals Fail

I’ve seen aftermarket manuals that swap the left and right control arms, that use a generic hydraulic schematic that doesn’t match the Rexroth pump in your 6625. This is the original GEHL Service Parts Manual (Form No. 904396). It tells you the part number for the grade 5 cap screw and whether it’s cadmium plated. Aftermarket books skip those details. Every time I work on a machine that’s been “repaired” with an aftermarket manual, I find stripped threads or wrong seals. Save yourself the headache. This copy comes from the OEM print, not a reprint of a scanned copy.

Who Needs This Manual and How to Use It

If you own a GEHL 6625 skid loader – whether you’re a farm operator, a rental yard, or a mobile mechanic – you need this. The manual is laid out in logical sections: start with the decal locations (pages 2-5) to confirm your machine’s SN range. Then jump to the section you’re repairing. For example, if the lift arm won’t lower, go to Lift/Tilt Cylinders & Hydraulic Components (pages 26-27). Parts lists are indented with the associated hardware – cotter pins, set screws, etc. – included in the list even if not drawn. That’s factory discipline. To order parts, you specify the part number from these pages, and the dealer will have no confusion.

3 Reasons to Choose OEM Documentation Over Generic PDFs

First, serial number breaks matter. This manual distinguishes units Before SN5901 vs. After SN5901 for auxiliary hydraulics (pages 28-31). Second, the hardware grade specification – all cap screws are Grade 5 unless marked otherwise. Third, the abbreviation table on page 2 defines every term from AMP to RTV. You won’t find that in a $9 access from a random site.

Frequently Asked Questions

Does this manual include the Engine overhaul procedure?

It covers the Engine & Related Components section (pages 14-15) with the fuel system, air cleaner, muffler, and radiator. You get exploded parts views and part numbers, but not step-by-step rebuild instructions. For that you’d need the separate engine service manual.

What torque values are listed in the GEHL 6625 Service Manual?

Page 2 gives ft-lb and inch-lb torque references for cap screws and nuts via the abbreviation table. Specific torque specs for cylinder bolts and pump fasteners are noted per assembly in the hydraulic section (pages 37-46).

Can I use this manual to repair the hydrostatic drive?

Yes. Pages 22-23 show the Hydrostatic Drive Components – both the drive motor and tandem pump. The hydraulic section (pages 40-41) covers the Tandem Hydrostatic Pump with a full parts breakdown. You’ll need to match serial numbers for the proper pump variant.

Why is the Fuel system listed under Chassis and not Engine?

The Fuel Tank is physically mounted in the chassis area (pages 6-7) along with the grill and access covers. The Engine section (14-15) covers the fuel filter and lines near the engine. GEHL grouped the tank with the chassis for parts ordering convenience.

Access the Factory Manual today and keep a real copy on your bench. Every time I crack open this book, I find another detail that saves me a call to the dealer. It’s the difference between guessing a seal size and knowing it. Manual Transmission isn’t skid loader territory, but the discipline of using factory data applies to every machine on your lot. Manual Transmission – same principle: get the right specs before you turn a wrench.
