GEHL 4635, 4835 Parts Catalog – OEM Factory Manual

Aftermarket parts catalogs get part numbers wrong. I’ve seen guys order a whole hydrostatic pump because the aftermarket book listed the wrong seal kit. That’s a thousand-dollar mistake and a week of downtime. If you’re working on a GEHL 4635, 4835 Parts Catalog — this is the OEM factory book, Form No. 907807, straight from Gehl Company. No third-party re-keying, no copied diagrams. 142 pages, every bolt, hose, and bracket drawn and numbered the way the factory intended.

Torque Specifications: Why the OEM Values Matter

Page 2 of this catalog states: “Standard attaching hardware torque values are also provided on the inside back cover.” That’s where you’ll find the numbers for SAE and metric fasteners. For hydraulic fittings, the O-Ring Table and Recommended Coupling & Adapter Installation Torque Specifications are included — not guessed. If you’re used to aftermarket catalogs that skip these, you’ll appreciate having the actual inch-pound and foot-pound values right there. Over-torque a JIC fitting and you’ll split the O-ring; under-torque and you’ll have a leak that drips onto a hot turbo. This book ends that guessing.

O-Ring Table and Coupling Installation Torque

One section in this catalog that saves real time is the O-Ring Table. It lists dash sizes, cross-sections, and the correct coupling installation torque for each fitting. If you’re rebuilding a GEHL 4835 SXT Turbo or a standard 4635, you’ll find the exact O-ring part numbers. No need to measure the old one and hope. The manual also warns: use only genuine GEHL service parts. Aftermarket O-rings may have the wrong durometer or compound — hard seals cause weeping, soft ones extrude. That’s not a theory; I’ve pulled apart customers’ machines that were rebuilt with cheap seal kits, and every failure traced back to a wrong O-ring.

Numerical Index: Finding the Right Part Fast

Before you can order a part, you need the right number. The Numerical Index in this catalog indexes every part number to the exploded view page and item number. You don’t flip through 142 pages hoping to spot the diagram. Look up the part number in the index, turn to the page, and confirm the illustration. That’s it. The introduction on page 2 also explains how to read the part description abbreviations — from AMP to SQ. Everything is in imperial units unless marked metric. If you need a battery, the manual tells you: “Replacement batteries are not provided by the GEHL Company … ALL REPLACEMENT BATTERIES MUST BE PURCHASED LOCALLY.” Straightforward.

Section A: Main Loader Components Coverage

The catalog is organized by sections, starting with Section A: Main Loader Components – Chassis. That’s the frame, axles, mounting brackets, and the decals. Each exploded view shows the assembly with callouts and a parts list table next to it. The table includes the part number, description, quantity, and any special notes — like “(AR)” for As Required, or “(NILN)” for Nylon Insert Lock Nut. If a part requires a nonstandard torque, it’s written behind the part number description in parenthesis. That level of detail is why factory manuals beat aftermarket summaries. GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog gives you that same OEM quality for comparable machines.

GEHL 4635 vs 4835: What the Catalog Covers

One catalog covers both the 4635 and the 4835 — including the 4835 SXT Turbo. The difference? The 4635 is naturally aspirated; the 4835 SXT Turbo has a turbocharger and slightly different engine components. The parts book separates them in the diagrams and parts lists, so you order the right piston, gasket, or turbo support bracket. If you’re not sure which model you have, check the serial number decal inside the right chassis riser — the catalog tells you exactly where to find it. For later models, see the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs or the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual.

Source Authenticity: Why OEM Beats Aftermarket

This isn’t a reprint from a third-party. It’s the original PDF from the Gehl Company, Form No. 907807. The inside cover states: “GEHL Company reserves the right to make changes or improvements … without incurring the obligation to install such changes on any previously delivered units.” That legal language tells you this is the official document. Aftermarket catalogs often copy the diagrams but scrub the part numbers or substitute generic hardware. That’s dangerous when you’re ordering a $800 hydraulic cylinder or a $300 driveshaft. Stick with the factory source. If you want to understand the diesel engine side of your loader, read this Wikipedia article on diesel engines.

Does this parts catalog include torque values for hydraulic fittings?

Yes. The O-Ring Table and Recommended Coupling & Adapter Installation Torque Specifications are in the table of contents. Torque values are in foot-pounds and inch-pounds, imperial units.

What is the difference between the 4635 and 4835 models?

The 4635 is naturally aspirated. The 4835 SXT Turbo has a turbocharger and different engine-related parts. The catalog separates them in the diagrams and part lists.

How do I use the numerical index?

Find your part number in the Numerical Index. It lists the page number where that part appears in an exploded view. Flip to that page, locate the item number, and verify the illustration. No guesswork.

Can I use this to order parts for a GEHL 4835 SXT Turbo?

Yes, the catalog covers both the 4635 and the 4835 SXT Turbo. Make sure you have the correct serial number to identify which sub-model you have. The catalog tells you where to find the serial number decal on the machine.

You’ve got a GEHL in the bay. You need the right part number the first time, not after returning two wrong seals. This 142-page factory catalog gives you the exploded views, the OEM numbers, and the torque specs that aftermarket books leave out.
