GEHL HL 2500 Parts Catalog – 36 Pages of Factory Part Numbers

If you’re tired of chasing part numbers from third-party websites that give you a picture of a bolt that might be close enough, this is your wake-up call. I’ve been wrenching for 28 years, and I can spot a reprint from three bays away. GEHL HL 2500 Parts Catalog is the real thing – a 36-page factory document that shows you exactly what part goes where and what number to order. No guesswork, no “this should fit” nonsense. You need the right hydraulic valve? The part number is right there. You need to know which decal set to buy? Page 3. This catalog is what I hand a junior tech when he’s pulling his hair out over a misordered lift cylinder. It works.

36 Pages of Factory Part Numbers

This isn’t a service manual with torque specs – it’s a parts catalog. Every page from 2 through 35 is packed with exploded-view illustrations and callouts. The introduction on page 2 tells you exactly where to find the serial number (left side of the upper frame cross member) and defines right vs. left from the operator’s seat. That alone saves you from ordering a left-side decal when you need the right one. The Numerical Index on pages 33-35 lets you cross-reference any part number back to the illustration. If you’ve ever spent an hour flipping through a generic catalog looking for a banjo fitting, you’ll appreciate this.

Engine and Transmission: What You Get

Page 6 covers the Engine assembly – all components from the block to the air cleaner. Need to identify the fuel injection pump bracket? It’s called out with a part number. The Transmission section on page 10 gives you the same treatment: every gear, shaft, and seal listed. And because GEHL didn’t assume you’d never need the hydrostatic drives, they split them into right and left – pages 31 and 32. I’ve seen backyard mechanics order the wrong drive motor because they didn’t know left from right. This catalog slaps you straight. Also buried in there: the Electrical system on page 14 with Wiring callouts for the trailer harness (page 26 for Trailer Wiring). That’s where you find the exact connector part numbers instead of spending twenty bucks on a generic plug that melts.

Hydraulic System, Valves, and Wiring

The Valve sections are critical. Lift and Tilt Valve on page 29, Hydraulic Control Valve on page 30 – each has an exploded view with individual parts. The Hydraulic Gear Pump is on page 28. If you’ve ever rebuilt a pump only to have it leak because you reused a worn o-ring, you know why you need this book. Every seal, every spring, every cartridge has its own part number. I’ve seen guys order a whole pump assembly when all they needed was a $3 seal. That’s the difference between a parts catalog and a parts catalog. The Hydraulic System overview on pages 12-13 shows the whole circuit layout – useful for tracing lines and identifying hoses. And the Optional Attachments section (pages 15-22) covers actuators, trailers, and more. Everything is factory-sourced, not reverse-engineered.

Are Optional Attachments Covered?

Yes – pages 15 through 22. That’s eight full pages dedicated to optional attachments like the Actuator (page 23), Trailer (pages 24-25), and Trailer Wiring (page 26). If you’re running a pallet fork or a snow blade, the part numbers for the mounting brackets and hydraulic lines are right there. This isn’t an afterthought. GEHL put the same level of detail into the add-ons as the base machine. And because the manual is 36 pages total, you’re not wading through irrelevant sections for a different model. It’s HL 2500 only – no SL4640 nonsense mixed in. If you need parts for other models, check the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog or the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs. For the RS6-34, grab the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual.

Order Parts the Right Way

Here’s where most people screw up: they call a dealer and say “I need a hydraulic pump for a HL2500.” The dealer doesn’t know which pump revision you have. This catalog gives you the exact part number – you read it off the illustration and that’s what you order. No returns, no wrong boxes. I’ve had too many comebacks because a guy eyeballed a seal. If you want to understand how the diesel engine works in context, check this Wikipedia article on diesel engines for background theory. For a deeper dive on the HL’s engine family, this Wikipedia article on diesel engines is worth a skim. But for ordering parts? Stick with this catalog.

Can I use this manual for a GEHL SL4640?

No. This is for the HL 2500 only. The SL series has different frames, hydraulics, and attachment interfaces. Order the correct catalog from our related manuals.

Does it include torque specifications for the head bolts?

No. This is a parts catalog, not a service manual. Torque values and repair procedures are in the service manual. This catalog gives you part numbers and exploded-view illustrations to order the correct components.

How do I find the serial number location?

Page 2. It’s stamped on a plate on the left side of the upper frame cross member. Also, the decal set number is 600251 – you’ll find that on page 3. Always quote the serial number when ordering parts.

Are decal part numbers included?

Yes. Page 3 lists the decal set (600251) and each individual decal with its part number: 045698 for the GEHL logo, 052141 for the model number, 053753 for the console warning, and so on. Do not order decals separately – always order the set to get the correct adhesive and color.

Bottom line: this is a factory-original PDF, not a scanned reprint – no blurry pages, no clipped illustrations. You get all 36 pages in high resolution. Print them out, laminate the ones you need for the shop, and keep the digital copy on your tablet. When you need to order a replacement valve spool or a wiring harness for the trailer lights, you pull up the exact part number. Stop wasting time and money on parts that don’t fit. Access the Factory Manual now and get back to working – not guessing.
