GEHL 6625 Parts Catalog

If you’re rebuilding a GEHL 6625 Parts Catalog skid loader and you’re stuck guessing part numbers, this catalog is what you need. I’ve torqued more bolts than most techs have seen, and I can tell you that guessing a fastener grade or torque spec on a loader bucket cylinder is a fast way to strip threads or snap a bolt. This is the OEM factory parts catalog, 96 pages, covering SN 7605 and later, with the Perkins 204-30 engine. It’s not a reprint or a copy. It’s the real Form No. 907286.

Torque Specifications: The Exact Values You Need

Factory torque specs for standard attaching hardware are printed on the inside back cover. The catalog also includes a dedicated O-Ring Table and Coupling & Adapter Torque Table. That’s two separate torque references you can trust. Every cap screw listed in the parts breakdown is grade 5 unless noted otherwise. Use the wrong torque on a hydraulic fitting and you’ll be replacing O-rings inside a week. This catalog gives you the numbers – no aftermarket approximations.

Numerical Index – How to Find Any Part

Page 2 of the manual covers ordering procedure: you need the correct part number, description, quantity, plus the unit model and serial number. The Numerical Index lists every part number in alphanumeric order. Each entry cross-references to the figure and page where the part is illustrated. No flipping through pages randomly. You go from index to figure, match the callout, and you’re done. Dimensions are in inches. All abbreviations – CS (cap screw), LN (lock nut), HYD (hydraulic) – are explained in the front matter.

O-Ring Table and Coupling Torque: Sealing the Hydraulics

Hydraulic leaks on a skid loader cost you time and fluid. The O-Ring Table lists both the O-ring sizes and the torque values for the couplings and adapters. That’s not something you find in a generic parts list. This is factory data from the same engineers who designed the 6625’s hydraulic circuit. Use the table to avoid over-torquing a brass fitting or under-torquing a JIC swivel. If you want background on diesel engine fundamentals, check out this Wikipedia article on diesel engines.

Parts Listing Format – Understanding the Abbreviations

Parts shown without a part number are reference only – not available for purchase. The catalog uses a standardized abbreviation list (FHSCS for flat head slotted countersunk, SHCS for socket head cap screw, etc.). Pay attention to grade designations: all hex nuts for grade 5 screws are grade B; others are grade A. That matters when you order replacement hardware. The catalog also notes that replacement tires and batteries must be purchased locally – GEHL only supplies wheel sets and battery specs via the “Battery & Engine Electrical Wiring” pages.

Audience Fit – Who Should Get This Catalog

DIY mechanics rebuilding a 6625 in their home shop. Small equipment owners who want to order the right parts the first time. Even experienced techs will use this when a loader comes in with a torn hydraulic line and they need the exact part number for the fitting. Pair this catalog with the GEHL 6625 6625sx Parts Catalog for the same data in a different binding, or go to the GEHL 6625 Service Manual – Factory Specs for Skid Loader Repair if you need full repair procedures. For other GEHL models, see the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog.

Source Validity – Why OEM Beats Aftermarket

Aftermarket parts catalogs often use generic illustrations and skip torque tables. This one comes straight from GEHL Company. The same company that built the loader wrote this manual. The introduction states they reserve the right to make design changes without obligation to update earlier units – so you’re getting the version that matches your serial number range (7605 and later). No guesswork, no third-party transcriptions. If you want to understand the engine platform, read this Wikipedia article on diesel engines.

Does this parts catalog include torque specifications?

Yes. The inside back cover lists standard attaching hardware torque values. The O-Ring Table and Coupling & Adapter Torque Table are also included.

Can I use this catalog to order parts directly from GEHL?

No. You must order through a GEHL dealer. The catalog gives you the correct part numbers so you can provide them to your dealer. Replacement tires and batteries must be purchased locally.

How do I read the part numbers in the numerical index?

The numerical index lists every part number in alphanumeric order, cross-referenced to a figure and page. You locate the figure to see an exploded illustration with callouts matching the part number. The catalog uses standard abbreviations (CS = cap screw, LN = lock nut). All dimensions are in inches. Cap screws are grade 5 unless specified. This system prevents ordering the wrong component. It is not a service manual – it is purely for parts identification and ordering. Using the index correctly saves you from buying a part that does not fit, especially on hydraulic fittings where thread type matters.

Is this the same as the service manual?

No. A service manual includes repair procedures and diagnostics. This parts catalog only lists part numbers, illustrations, and torque specs. You need both for a full rebuild.

Access the Factory Manual now and stop guessing part numbers on your GEHL 6625. 96 pages, factory torque data, and a numerical index that makes ordering the right part a straight shot. No fluff, no reprints – just the OEM document.
