GEHL SL5635, SL6635 1997 Workshop Manual

If you are pulling wrenches on a GEHL SL5635 or SL6635 skid loader, you need this GEHL SL5635, SL6635 1997 Workshop Manual on your bench. Not a aftermarket rehash – this is the original GEHL factory PDF, 188 pages of the exact procedures the dealer techs use. I have been doing this 28 years, and I can tell you the difference between a spec out of a factory manual and one out of a Chilton’s is the difference between a job that stays tight and a callback that costs you Saturday.

What’s Inside the GEHL SL5635 SL6635 Workshop Manual

Specifications start on page 1-1 with tire options, bucket capacities, and general specs. You get the data in imperial units – fluid capacities in quarts, torque in foot-pounds, tire pressures in psi. The Safety chapter (page 2-1) covers the mandatory shutdown procedure, lift cylinder mechanical lock, ROPS raising and lowering, and relieving hydraulic pressure. I have seen guys skip that step and lose a hand. Read it.

Lubrication details on page 3-1 give you hydraulic oil reservoir volumes, crankcase oil grades, chaincase fills, and grease fitting locations. The Mainframe chapter (page 4-1) walks through engine access cover removal, ROPS, seat, lift arm, and control cover installation. Wheel Drives (page 5-1) covers chain adjustment, axle housing, and wheel bearing disassembly. Controls (page 6-1) includes control handle adjustment, tracking, and crosstube removal. All written for the SL5635 and SL6635 models – no guesswork.

Safety First: The Mandatory Shutdown Procedure

Page 2-2 spells out the mandatory safety shutdown procedure. It tells you exactly how to lower the loader, engage the cylinder mechanical lock, and relieve hydraulic pressure before you stick any tool near the lift arms. The manual includes cylinder lock engagement and disengagement steps (page 2-3 and 2-4) with diagrams. If you are new to skid loaders, do not skip this section. I do not care if you have fixed a hundred tractors – every machine has its own lock sequence.

Torque Specs and Fluid Capacities – Page 1-1

Specifications sheet gives you the numbers you cannot guess. Bucket capacity, rated operating load, travel speed, and hydraulic system pressure. No “tighten until it feels right.” You get foot-pounds for axle nuts, inch-pounds for control panel bolts, and proper fluid types for the hydraulic reservoir and chaincases. Use those numbers. I have seen stripped frame bolts because someone used a generic spec from the internet.

Lubrication and Hydraulic Reservoir – Page 3-1

The lubrication section lists every grease point, oil type, and capacity. Hydraulic oil reservoir fill procedure, crankcase oil change intervals, chaincase level checks. It even shows you where all the grease fittings are on page 3-4. If you ignore that schedule, you will be replacing axle bearings inside two seasons. The manual tells you exactly which SAE grade goes in each location.

Does This Manual Cover the Controls and Wheel Drives?

Yes. Chapter 6 (Controls) covers T-bar, hand/foot, and dual hand control configurations. Control handle removal, position adjustment, tracking adjustment for traction controls. Left and right control handle assembly breakdown (page 6-5 and 6-10). Wheel Drives chapter gives you drive chain adjustment specs, chain removal, axle housing assembly, and idler sprocket bearing service. If you need to rebuild the drive system, you have the factory steps – not a generic “remove and replace” paragraph.

Why OEM Documentation Matters

Aftermarket manuals guess at torque values, skip safety steps, and use generic wiring diagrams. This one is scanned from the original GEHL binder. It has the GEHL part numbers, form number 907285, and the dealer-approved procedures. When you need to know the exact sequence for lift arm bushing replacement (page 4-13) or the correct way to adjust the control handle tracking, you want the page that the factory wrote. I will not touch a machine with aftermarket instructions – it is not worth the liability.

For related factory documentation, check out the GEHL SL5635 SL6635 1999 Engine Parts Book if you need engine component breakdowns, or the GEHL SL5635 SL6635 1999 Parts Catalog for full machine parts illustrations. If you have a broader model range, the GEHL SL4635 SL4835 SL5635 SL6635 2005 Parts Catalog covers additional years.

Need a separate reference for drivetrain fundamentals? The Manual Transmission article on Wikipedia explains gear ratios and clutch basics that apply to the SL5635/6635 drive chains. Another useful overview is the Manual Transmission page – same topic, but note that this manual covers the specific chain drive setup, not a traditional gearbox.

What models does this workshop manual cover?

GEHL SL5635 and SL6635 skid loaders – SX, DX, and Turbo variants.

Is it a reprint or a scan?

This is a direct digital copy of the original 1997 GEHL Shop Manual, form number 907285. It is not a reprint – scanned from the factory binder with all pages intact.

Can a beginner use this manual?

It was written for experienced technicians, but beginners can follow it if they pay attention to the safety warnings and torque specs. The manual assumes you understand basic mechanics – it does not teach you how to use a wrench. Chapter 2 (Safety) is mandatory reading before any disassembly. If you are brand new, read the mandatory shutdown procedure on page 2-2 twice, then find a mentor to watch your first lift arm removal.

Does it include wiring diagrams or hydraulic schematics?

The table of contents does not list a separate electrical section, but the Controls chapter (6-1) includes control handle linkages and cable adjustments. Hydraulic system pressure specs are in the Specifications section (page 1-1). For full hydraulic hose routing and valve body diagrams, you would need the separate GEHL parts catalog – the workshop manual focuses on removal, installation, and adjustment procedures.

If you plan to keep your GEHL SL5635 or SL6635 running for the next decade – and you should, because those machines are built – get the factory documentation on your hard drive. Access the Factory Manual now and stop relying on forum advice.
