GEHL SL3510, 3610 Parts Catalog – Factory OEM Parts Breakdown

Let me tell you straight – if you’re ordering parts for a GEHL SL3510 or 3610 without the factory parts catalog, you’re wasting time and money. I’ve worked on these skid loaders for years, and the difference between a correct part number and a close guess can mean a machine down for a week while you return the wrong bearing. This GEHL SL3510, 3610 Parts Catalog is 104 pages of OEM part numbers, exploded views, and serial-number-specific splits that keep you from ordering a fuel tank that doesn’t fit. No aftermarket reprint – this is the original factory document GEHL printed for service departments.

104 Pages of Factory Part Numbers – What’s Inside

Every section in this manual is organized by system and serial number range. You get the chassis, fuel tank, rear grill, and access covers starting on page 4. Then overhead guard and seat assemblies split into two serial-number groups – one for after SN1922-3510, one for before. That’s the kind of detail you need when the dealer asks, “What’s your machine’s serial?” Axles and drive chains are on pages 12-13. Instrument panel, wiring, and battery gets three separate serial-number breaks (pages 14-19). The manual doesn’t treat all SL3510s the same; it respects that later machines have different wiring harnesses and electrical components.

Engine and Fuel System Coverage – Gas and Diesel

Gas engine sections run from page 38 to page 45, split across four serial-number ranges. The SL3610 diesel engine gets its own pages 46-49. You get the muffler, air cleaner, and alternator assemblies with three serial breaks. The fuel system ties into the chassis and fuel tank detail on pages 4-7. For anyone rebuilding or replacing an engine, having the correct part numbers for gaskets, pistons, or fuel injectors saves a parts run mid-job. I’ve used similar GEHL manuals to pull a diesel head; you can cross-reference the fuel lines and injection pump components without digging through a generic aftermarket book that left out half the variants.

Wiring and Electrical Diagnostics – Factory Diagrams

Wiring is where most manuals fall short. This one gives you three separate wiring and battery sections based on serial number. Each one shows the instrument panel, battery connections, and wiring harness routing. If you’re chasing a no-start or a dead electrical circuit, you need to know if your machine has the late or early harness. The manual also covers work lights, warning lights, horn kit, and back-up alarm options (pages 74-89). For more background on diesel engine electrical systems, check out this Wikipedia article on diesel engines – it explains the basics, but for part numbers, you stick with this factory catalog.

Serial Number Breaks – Why They Matter

Every experienced mechanic knows that one serial-number change can swap out a pump, a wiring harness, or even a radiator. This manual separates the hydrostatic system into three ranges for the SL3610 alone. Radiator sections cover seven different serial-number combinations. If you order a radiator for an SL3510 after SN2419, you need page 56-57. Before that? Different pages. The “Attaching Hardware Table” on the inside back cover lists torque values for standard fasteners. Never guess a torque spec on a gear pump or a relief valve – the manual gives you the OEM values right there. I’ve seen stripped threads caused by guessing; use the factory spec.

Hydraulic Components and Options – Complete Parts Breakdown

Pages 66-73 cover hydraulic pumps, motors, valves, and cylinders with individual exploded views. Columbus tilt and lift cylinders, Webster gear pump, relief valves (1000 and 1200 PSI), main control valve, drive piston pumps for left and right sides, hydrostatic drive motor – all broken down. The options section includes grapples, buckets, manure forks, backhoe adapting packages, auxiliary hydraulics, sound deadening kits, and door wipers. Need a part number for the spark arrestor muffler kit? Page 79. The numerical index (pages 91-97) lets you look up any part number fast. If you work on other GEHL models, you might also need the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog or the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs. For a newer machine, GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual is a solid resource.

Can I use this manual to rebuild the entire engine?

This is a parts catalog, not a service manual. You get part numbers and exploded views, not step-by-step rebuild instructions. For assembly torque sequences, you need the factory service manual alongside this catalog.

Does it cover the fuel system for both gas and diesel?

Yes. The chassis section includes the fuel tank. The engine sections list fuel-related parts for the gas and diesel variants. No separate fuel system chapter exists, but every component appears in the applicable subsystem pages.

Will the wiring diagrams help me troubleshoot an electrical issue?

You get the wiring harness layouts as assembly drawings, not full schematic diagrams. They show connector locations, wire routing, and battery connections. Useful for tracing harness damage, but if you need a wiring schematic with voltage values, that’s a different document.

How do I know which serial-number section applies to my loader?

Find the serial number decal inside the right chassis riser between the lift arm and lift cylinder. Compare that number to the ranges listed in the manual’s headings. The manual uses clear “After SN…” and “Before SN…” labels for each section.

Bottom line: if you need to order parts for a GEHL SL3510 or 3610, having the factory parts catalog stops the guesswork. No aftermarket shortcuts, no missing illustrations. 104 pages of OEM data, including torque specifications on the inside back cover. Access the Factory Manual and start ordering the right parts.
