GEHL SL5635, SL6635, 5635 1999 Parts Catalog

You are rebuilding a Deutz BF 4M1011F in a GEHL skid loader and the parts counter guy is reading you numbers that don’t match anything on your bench. Then he asks for a serial number from a plate he can’t locate. That is exactly when you need this GEHL SL5635, SL6635, 5635 1999 Parts Catalog in your hands — 68 pages of factory-issued part numbers, exploded diagrams, and index references that tell you exactly which bolt goes where. Aftermarket catalogs are fine for rough ideas, but when a camshaft costs serious money, you order by the OEM number or you eat the return shipping.

What’s Inside the Engine Parts Book

This is not a repair manual. It is a parts catalog, straight from GEHL, dated 09/99 (Form 907763 Revision B). Every section in the table of contents matches a real component group on the Deutz BF 4M1011F: Camshaft (page 19), Camshaft Drive (page 18), Crankshaft (page 8), Connecting Rod (page 12), Piston (page 13), Cylinder Head (page 16), Cylinder Head Fastenings (page 15), Fuel Injection Pump (page 33), Turbocharger (page 41), Rocker Arm Bracket (page 21), and 50 more groups right through Gasket Set (page 60) and the Index (page 61). Each group has an exploded illustration with callouts linked to GEHL part numbers. No aftermarket renumbering, no “equivalent to” footnotes.

Which Engines and Serial Numbers Are Covered?

Pages 1–2 of the catalog state clearly: this covers Deutz BF 4M1011F engines (GEHL part number 130320) used in SL5635SXT, SL5635DXT, SL6635SXT, and SL6635DXT skid loaders before engine serial number 0262361. If your engine is after that SN, you need a later revision. The manual tells you to locate the engine serial number on a plate on the valve mechanical cover — that detail alone saves you from ordering the wrong camshaft or cylinder head. OEM documentation like GEHL SL5635 SL6635 1999 Parts Catalog gives you the exact cutoff.

3 Reasons to Use Factory Parts Documentation

First, part numbers change. GEHL reserves the right to update numbers without notice. This catalog is the baseline. Your dealer checks his system against a number that originates here. Second, the exploded views show how every component fits — for example, the Camshaft Drive group on page 18 includes the idler gear, thrust washer, and mounting bolts. No guessing. Third, the index at page 61 lets you find any part by name in seconds. I have had guys order a “fuel supply pump” and get the wrong one because they didn’t check the page 34 illustration. That mistake costs a day.

Is This Manual Right for a Beginner?

Yes, if you need to order parts for a GEHL SL5635, SL6635, or 5635 skid loader. Keep in mind this is not a step-by-step repair guide. It does not tell you how to R&R a camshaft or torque a cylinder head. What it does is show you what the factory calls each piece — the Dipstick (page 2), Fuel Injector (page 35), Glow Plug (page 42) — and gives you the part number to hand to your dealer. Beginners should pair this with a factory service manual for the actual wrenching instructions. For the parts side, this PDF is the source of truth. Read this Wikipedia article on diesel engines if you want background on the BF4M1011F design.

Source Authenticity: OEM vs Aftermarket

Every line in this catalog was printed by GEHL in 1999. The pages are scans of the original book, not a reprint with third-party numbers. I have seen aftermarket parts catalogs that “correct” the OEM camshaft part number because some intern thought it was wrong. That ends with a cam that does not fit the gear train. This document is the factory file — this Wikipedia article on diesel engines explains why that matters on interference engines. If you want the same parts list the GEHL dealer uses, this is it.

FAQ

Does this catalog cover the SL4635 or SL4835 models?

No. It covers SL5635 and SL6635 only, with the 5635 Turbo variant.

I see “Before SN 0262361” on page 2. Can I still use this for a later engine?

Some parts may cross over, but GEHL revised internal components after that serial number. The camshaft, cylinder head, and fuel injection pump groups could differ. Order parts by your engine serial number, not by model alone. Use this catalog as a reference but verify with your dealer if your engine is past the cutoff. The index on page 61 helps you cross-check descriptions, but the final responsibility is on you to confirm the part numbers match your specific engine. I have had a job sit for a week because someone ignored the serial number break and ordered a camshaft that had a different keyway location.
