GEHL SL4640E, SL5240E 2008 Parts Catalog

If you’re turning a wrench on a GEHL skid-steer and you order the wrong hydraulic fitting because you guessed at the part number, you’ve just burned an hour and pissed off the customer. That’s exactly why this 2008 GEHL SL4640E, SL5240E 2008 Parts Catalog belongs on your bench – not some aftermarket PDF that leaves out the O-ring table. I’ve torn down enough loaders to know that a mismatched adapter costs more in downtime than the goddamn manual does.

What This 238-Page Parts Catalog Actually Covers

Four main sections. Section A: MAIN LOADER COMPONENTS. Section B: HYDRAULIC COMPONENTS. Section C: KITS & ACCESSORIES. Section D: SCHEMATICS. Then a Numerical Index and two critical reference tables – O-Ring Table and Coupling & Adapter Torque Table. 238 pages total, published 05/08, revision B. This is the factory document that GEHL dealerships used to order parts. No guesswork.

Torque Specs for Hydraulic Fittings – Right in the Manual

Page 2 tells you standard attaching hardware torque values are on the inside back cover. Then there’s a dedicated Coupling & Adapter Torque Table. If a fitting requires a nonstandard torque, it’s called out right behind the part number. That’s the kind of detail that keeps a JIC fitting from leaking after a week. I don’t care how good your arm-calibration is – use the spec from the O-Ring Table page.

Why OEM Parts Catalogs Beat Aftermarket Copies

Aftermarket parts lists love to omit the abbreviation table (AR, HEX, H/F, etc.) and skip the serial-number cutoffs. This catalog explicitly covers SL4640E (EU) with serial number 310601 and up, and SL5240E (EU) with the same range. If you’re working on an earlier machine, you need the GEHL SL4640 SL4840 SL5640 2009 Parts Catalog or the GEHL SL4640E SL5240E 2010 Parts Catalog. The factory revision B note says GEHL reserves the right to change designs – you need the exact revision for your build date.

Who Needs This Manual? (Spoiler: Anyone with a SL4640E or SL5240E)

If you own one of these machines, or you’re a shop that rents them out, this parts catalog saves you from cross-referencing worn-out decals. The hydraulic schematics in Section D show line routing. Want to know which battery to buy? Page 2 says replacement batteries are not GEHL-supplied – check the Electrical-Chassis chapter. For diesel-engine-specific parts like injection pump or turbo, reference this Wikipedia article on diesel engines for general operation context, but come back to this catalog for genuine part numbers.

Get the Right Part Number the First Time

Every exploded-view diagram in this catalog has a clear callout. Items shown without a number are for reference only – not available. The abbreviation list includes CCA (Cold Cranking Amperage), FOPS (Falling Object Protective Structure), and others you’ll see on actual GEHL parts. The Numerical Index at the back lets you find a part number if you already have it but need the location. Pair this with the GEHL SL4640E SL5240E Operator’s Manual for service intervals, and you’ve got a complete package.

Does this manual include part numbers for the hydraulic pump?

Yes – Section B lists all pump sub-components with GEHL part numbers.

I have a SL4640E with serial number below 310601 – will this work?

This revision (B, 05/08) covers SL4640E (EU) SN 310601 and up and SL5240E (EU) SN 310601 and up. If your machine is older or a non-EU variant, you need the GEHL SL4640 SL4840 SL5640 2009 Parts Catalog or the GEHL SL4640E SL5240E 2010 Parts Catalog for earlier serial numbers. The O-ring table and torque specs are specific to the 2008 revision – later catalogs may have updated values. For diesel engine fundamentals, see this Wikipedia article on diesel engines.

Bottom line: you need factory part numbers and torque specs that actually match your machine. Access the Factory Manual now – it’s the same PDF dealerships use, not a reprint from some third-party site. 238 pages, OEM data, no shortcuts.
