GEHL SL4635, SL4835 Operators Manual – Factory Specs for Skid Loaders

I’m Mike Callahan, ASE Master since ’96. I run a six-bay shop in San Antonio, and I’ve torqued more head bolts than most people have had hot meals. When a customer rolls in with a SL4635 or a SL4835 that won’t move, I reach for the factory binder – not a third-party PDF that’s been copied three times and lost half the torque specs. This GEHL SL4635, SL4835 Operators Manual is the real deal. 86 pages, printed in the USA, straight from the source. No guesswork, no rewritten garbage.

Model Specifications and Machine Identification

Chapter 2 of this manual gives you the exact weights, dimensions, and fluid capacities for both the SL4635 and the SL4835. The serial number decal location? Right inside the right chassis rail – they tell you where to look so you don’t waste time hunting. Page 4 has the breakdown. Write your numbers on the identification page inside the front cover, because if you call Gehl for parts without the serial number, you’re wasting everyone’s time. I’ve seen too many DIY guys order the wrong filter because they skimmed a generic list. This manual stops that.

What Torque Values Are Listed?

Torque specs are on page 80. Wheel lug nuts, hydraulic fittings, engine mounting bolts – they’re all in there with exact foot-pounds. I don’t trust aftermarket torque charts; they’re often one-size-fits-all and that’s how you snap a bolt in the final drive. This factory manual gives you the values Gehl designed for. If you’re rebuilding a control handle or adjusting the drive belt, you need those numbers. One stripped hole in the axle carrier costs more than this manual.

11 Chapters Covering Operation and Service

There are 11 chapters plus an index and inside-cover warranty. Chapter 3 is the checklist section – pre-start, daily, and 10-hour checks. Chapter 4 is safety: lockout procedures, parking brake neutral, machine travel direction symbols. Chapters 5 and 6 cover controls and operation – how the joysticks work, float bucket position, engine start/stop procedures. Chapter 7 is adjustments, Chapter 8 lubrication (grease points and intervals), Chapter 9 troubleshooting, Chapter 10 service (fluid changes, filter replacements), and Chapter 11 the maintenance schedule. Each chapter builds on the last, like a proper field manual.

Safety and Controls: Factory Procedures

Page 10 starts the safety chapter. That section alone is worth the purchase. It tells you which symbols mean “read the manual,” which ones indicate hydraulic oil temperature, and the exact procedure for tying down the machine. The SL4635 and SL4835 have different control patterns? This manual shows both. I’ve had a helper crush a hydraulic line because he didn’t know the emergency stop location. Don’t be that guy. The factory safety decal locations are all mapped out.

Get the Right Maintenance Schedule

Chapter 11 lays out the maintenance schedule in hours – 10, 50, 250, 500, 1000. It matches the factory intervals Gehl tested. Use that to plan oil changes, filter swaps, and hydraulic fluid checks. I keep a copy in the break room so my techs check it before every major job. If you’re a DIY owner, print the lubrication section (page 49) and stick it to the inside of your toolbox. It’ll keep your loader running longer than any YouTube tip.

Don’t waste money on a reprint that’s been scanned from a copy of a copy. This is the original OEM print. It includes the index and the torque specs on page 80. When you’re looking for the proper procedure to adjust the drive belt or diagnose a turbo issue, you won’t find it in a generic manual. You’ll find it here.

Does this manual cover the SL5635 or SL6635?

No. It is specifically for SL4635 and SL4835 models. Check the parts catalog for related models.

Is this an original OEM manual or a reprint?

This is a factory-original OEM manual. It was printed by GEHL. No aftermarket scanning or rewriting. You get the same document a dealer would use.

Will it tell me how to fix a dead engine?

Chapter 9 (Troubleshooting) covers common problems, but for engine teardown you need the service manual. This operators manual covers daily operation, maintenance, and basic diagnostics. For valve adjustments or turbo rebuilds, buy the service manual.

What’s on page 80?

Torque specifications. Wheel bolts, engine mounting, hydraulic fittings – all in foot-pounds. Also includes fastener grade recommendations. You will use this page every time you touch a wrench on these machines.

You need this manual on your bench if you own or work on a GEHL skid loader. No guesswork, no wasted trips to Google. Access the Factory Manual from AutoRepairManuals and keep it where you can reach it. Your wallet and your time will thank you.
