GEHL SL5635, SL6635, SL4635, SL4835 2005 Parts Catalog

Parts ordering mistakes cost time and money. I’ve seen techs pull a piston ring set from a generic supplier only to find the groove depth is off by a few thousandths. That’s a comeback you don’t get paid for. When you’re rebuilding a Deutz 1011F in a GEHL skid-steer, you need the exact part number from the factory. This 78-page GEHL SL5635, SL6635, SL4635, SL4835 2005 Parts Catalog is the document I put on the bench whenever I’m ordering bottom-end or top-end components. It covers the F3M 1011F and BF3M 1011F used in SL4635 and SL4835, plus the four-cylinder F4M 1011F and BF4M 1011F in SL5635 and SL6635. No aftermarket reprints, no blurred diagrams—original OEM print.

GEHL SL5635, SL6635, SL4635, SL4835 2005 Parts Catalog: What’s Inside

Open the manual and the Table of Contents hits you with 70 numbered sections, from the dipstick guide all the way to the gasket set and index. Every major engine system gets its own spread. Crankshaft? Page 8. Cylinder head fastenings? Page 15. Camshaft drive and gear? Pages 18–19. The book is laid out so you don’t flip back and forth trying to cross-reference a part that doesn’t exist. Each page shows an exploded view with callouts and a corresponding parts list. Need the exact part number for the fuel injector pump? Section starts on page 31. The manual even includes the torque capsule (page 50)—a separate section for critical bolt torques that aftermarket catalogs usually skip.

Engine Overhaul Coverage: Crankshaft to Camshaft

This catalog covers the full rotating assembly. Sections for crankshaft accessories (page 7), piston (page 13), connecting rod (page 12), and flywheel (page 11). The valve train gets its own chapters: rocker arm bracket (page 21), valve drive (page 22), valve mechanical cover (page 17). Each part is listed with a factory part number—no guessing which piston fits which bore size. I’ve used this catalog to order a camshaft for a SL5635 that had a wiped lobe. The part number on page 19 matched the engine serial number stamped on the valve cover. No returns, no delays.

Does This Manual Cover the Fuel System?

It does. From the fuel injector pump (page 31) to the injectors (page 32), fuel supply pump (page 35), fuel line (page 36), fuel filter (page 37), and high-pressure pipe (page 38). There’s also an overflow line (page 39) and a section for the suction pipe flange (page 40). If you’re replacing injection components on a SL6635 with the BF4M 1011F, you can confirm the injector part number against the engine plate without picking up a phone. The manual explicitly says to use only genuine OEM parts—Gehl Form No. 917115 Rev. B, dated 11/05.

3 Critical Systems the Manual Organizes

Lubrication system—oil pump (page 23), filter and fastenings (page 24), oil lines (pages 25–27). Every fitting and gasket is listed. Cooling and air intake—heater connection (page 28), radiator connection (page 29), turbocharger (page 43), charge air pipe and elbow (pages 44–45), air filter fitment (page 47). Electrical and controls—starter (page 58), alternator and its bracket/fastenings (pages 59–61), glow plug (page 48), oil pressure switch (page 63), temperature transmitter (page 64), control unit (page 68), shutdown device (page 69). If your SL4635 won’t start and you suspect the glow plug circuit, page 48 gives you the part number for the plug and the bus bar.

Get the Right Part Number the First Time

I’ve been wrenching for 28 years, and I still see guys waste an hour digging through three different websites to ID a part. This manual stops that. It’s 78 pages of straight factory data—no interpretation, no “this might fit.” The index at page 71 lets you look up any component alphabetically. For earlier machines, check the GEHL SL5635 SL6635 1999 Engine Parts Book and the GEHL SL5635 SL6635 1999 Parts Catalog. If you need the engine-specific parts listings, the GEHL SL5635 SL6635 Engine Parts Book covers that series. For a broader understanding of how these diesel engines work, this Wikipedia article on diesel engines gives good background—but for parts ordering, stick to the OEM document. You can also check this Wikipedia article on diesel engines for general theory. Your parts counter will thank you.

Is this a repair manual with step-by-step instructions?

No. It is a parts catalog for ordering correct OEM components. It shows exploded diagrams and part numbers, not removal or installation procedures.

How do I identify which engine is in my SL5635 so I order the right parts?

Locate the engine serial number plate on the valve mechanical cover (page 17 of the parts catalog shows that cover). The plate will list the engine model—F4M 1011F or BF4M 1011F. Cross-reference that with the manual’s introduction (page i) which specifies which engines go in which loaders. Then find the section for the component you need—crankshaft is page 8, cylinder head page 16, etc. Always quote the engine serial number when ordering, as the manual advises. This avoids getting a pre-2005 part that won’t fit the updated block casting. I’ve seen guys ignore that step and end up with a camshaft that didn’t match the bearing bore. Use the factory data.

When you need to order parts for a GEHL skid-steer with a Deutz 1011F, having the factory catalog on your screen saves phone calls and wrong shipments. Access the Factory Manual and keep it on your repair tablet or print the pages you need. I keep a copy in the shop for every SL5635 that rolls in. You should too.
