GEHL 4525, 4625 Parts Catalog – Factory Specs for Skid Loader Repair

Let’s be honest – nothing wastes a Saturday like ordering the wrong hydraulic fitting because you guessed at a part number. I’ve seen guys yank a lift arm off a 4625, only to find the replacement bushing is 0.030” too small. That mistake costs you time, money, and a trip to the parts counter that could have been avoided with the right book in the toolbox. The GEHL 4525, 4625 Parts Catalog is that book. Not a third-party rehash – the same Service Parts Manual GEHL printed for its dealers. 210 pages of factory-sourced part numbers, hardware tables, and torque specs that let you order once and fit the first time.

Page 1 gives you the model designations – 4525 and 4625 – and the part number for this manual (907263, replacing 907005). No guessing which revision you’re holding. The introduction on page 2 tells you exactly where to find your serial number (inside the right chassis riser, between the lift arm and lift cylinder) so you match the right parts to your machine. That’s the level of detail you need when a lift cylinder seal kit has to seat against a specific bore diameter.

Torque Specifications and Hardware Table – Why You Need Both

Torque values live on the inside back cover of this manual. They’re standard attaching hardware torques for Grade 5 cap screws and Grade B nuts – the same fasteners that hold your engine mount and wheel hubs. I don’t care if you’ve torqued bolts for twenty years; fatigue changes your wrist. You need the spec written down. This catalog gives you that. The Hardware Table lists every fastener type, abbreviation (CS, HHC, SHCS – you name it), and plating spec. If the manual says “GR5, zinc plate,” you know exactly what to grab from the bin.

There’s also an O-Ring Table in the front. Hydraulic leaks on a skid loader aren’t “minor” – a blown O-ring in the drive circuit dumps fluid fast. Cross-reference the dash number from the table and you’ll have the right diameter and durometer. No guessing if a 2-014 will substitute for a 2-012. It won’t.

What Does the 210-Page Parts Catalog Cover?

The Table of Contents lists Main Loader Components, starting with the Chassis, Fuel Tank, Grille, and Access Covers. That section alone saves you from buying a whole fuel tank assembly when all you need is a fuel cap gasket – the exploded diagram shows each piece separately, with a reference number tied to the parts list. Items without reference numbers are not sold individually (the intro makes that clear). You don’t waste time on the phone asking for something that isn’t available.

Other sections cover the engine, hydrostatic drive, lift arms, and electrical components. The Numerical Index at the front lets you look up any part number alphabetically or numerically. Need a replacement decal? The catalog points you to the Operator’s Manual for safety and decal location chapters – it’s a coordinated system, not a standalone document. For that, check the GEHL 4525, 4625, 3725, 3825 Operators Manual – Factory Specs for Skid Loaders for operation and safety decal positions.

3 Reasons to Trust GEHL’s Own Parts Manual

Reason one: Factory revision control. This manual replaces form 907005 and is printed in the USA. No aftermarket “reprint” that scans at 72 dpi and loses bolt callout lines. Reason two: The hardware table explicitly states “All Cap Screws or Bolts are Grade 5, cadmium or zinc plated; Hexagon Nuts for Grade 5 are Grade B.” You won’t find that guarantee in a generic parts breakdown. Reason three: The torque values come from GEHL’s own engineering – not some third-party guess. When the inside back cover says 45 lb-ft for a 3/8-16 Grade 5, that’s what your skid loader’s chassis was designed to handle.

Need a deeper dive into the engine itself? this Wikipedia article on diesel engines is a decent primer on four-stroke cycle basics, but the parts catalog gives you the exact piston ring set and gasket kit for the engine in your 4525 or 4625. If you’re doing a full rebuild, pair this parts catalog with the GEHL 4625 Workshop Manual – Factory Specs for Skid Loader for disassembly and assembly sequences. The workshop manual tells you how to take it apart; the parts catalog tells you what to put back in.

Chassis, Fuel Tank, Grille, and Access Covers: Factory Diagrams

That’s the first chapter after the front matter. Each component has an exploded view with numbered callouts. The parts list below uses abbreviations from the Hardware Table (e.g., “CS 3/8-16 x 1.00 GR5”). You identify the part, order by the GEHL number, and move on. No translating between aftermarket systems. For example, if you need the grille for a 4625, the diagram shows it with a reference number – you read down the list, get the GEHL part number, and place the order. This chapter also covers access covers (hinge pins, latches) that are often the first thing to crack on a high-hour machine.

For newer machines, the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog covers a later generation, but the 4525 and 4625 remain in the field. This manual is still current for those models. Diesel engine fundamentals are the same across decades – you can also reference this Wikipedia article on diesel engines for the theory, but stick to the factory parts list for actual dimensions.

FAQ – Common Questions About This Parts Catalog

Does this manual include wiring diagrams?

Not for the electrical system itself – it references the chapters titled “Wiring & Electrical Components” only for battery specifications. You need the workshop manual or a separate electrical schematic for wire colors and connector pinouts.

Can I use this catalog for a GEHL 3725 or 3825?

No. It is specifically for the 4525 and 4625 models. Check the GEHL 4525, 4625, 3725, 3825 Operators Manual – Factory Specs for Skid Loaders for multi-model coverage.

Are torque values for all fasteners listed?

Standard attaching hardware torques are on the inside back cover. Special fasteners (e.g., rod-end bolts, flywheel bolts) are not in this parts catalog; you’ll find those in the workshop manual.

How are replacement tires handled?

GEHL does not sell tires directly. Wheel sets are listed with tire size information so you can buy the correct tire locally. Batteries are also sourced locally – specifications are given in the electrical section.

If you’re tired of digging through three different websites to find a wheel seal part number, stop guessing. This catalog puts the entire GEHL 4525 and 4625 parts system in your hands. Access the Factory Manual and get back to wrenching.
