GEHL AL 140 2010 Parts Catalog – Factory Documentation

I’ve been turning wrenches since before some of you were born, and I’ve seen more aftermarket parts catalogs that show the wrong bolt size than I care to count. If you’re working on a GEHL AL 140 articulated loader built from serial number 11257 and up, you need the real thing. This GEHL AL 140 2010 Parts Catalog is 100 pages of factory drawings, part numbers, and torque specs. Not a reprint from some third party that thinks a 10-mm bolt is the same as a 3/8-inch. The manual includes the full Introduction page that explains how to read serial number breaks and fastener grades. You want to order a seal kit for the lift cylinder? The exploded view on page 38 shows exactly which o-rings and back-up rings go where. No guesswork.

Hydraulics Section: Real Diagrams, Not Shade-Tree Sketches

Look at the Table of Contents in this manual. You get a dedicated Hydraulics section starting on page 31, with subsections for the hydraulic tank, drive, power steering, control valve, and auxiliary valve. Each component has a parts list with reference numbers that match the illustration. The hydraulic cylinder pages (pages 38-41) cover the lift cylinder, tilt cylinder, steering cylinder, and Power-A-Tach cylinder. If you need the part number for the steering cylinder seals, you don’t call the dealer and describe it by color. You open the manual, find the circled reference number, and order the correct kit. That’s what factory documentation does. The this Wikipedia article on diesel engines explains why precise fuel systems matter, but this parts catalog gives you the actual numbers.

Engine and Fuel System: Get the Right Part Number the First Time

The engine section (pages 51-66) breaks down the GEHL engine assembly into cylinder block, gear housing, flywheel housing, cylinder head, camshaft, crankshaft, and pistons. You get separate pages for the fuel injection valve and fuel injection pump. The fuel line page shows every clip, hose, and fitting. I’ve had guys tell me they ordered a fuel injection pump from a generic supplier and the mounting flange was off by 2 mm. That’s wasted time and money. With this OEM manual, you read the part number straight from the diagram, cross-check the serial number break, and order the right piece. The this Wikipedia article on diesel engines explains injection systems generically, but your AL 140 needs specific numbers.

Axles and Lift Arm: Where Most Guys Mess Up Torque Specs

Page 26 covers the front and rear axles. The manual doesn’t give you a generic “tighten until snug” instruction. It references the inside back cover for standard attaching hardware torque values, including metric values in Newton-meters with a conversion factor to foot-pounds (multiply by 0.738). The lift arm assembly on page 30 shows every pin, bushing, and retaining ring. If you’re rebuilding the lift arm, you need the correct part numbers for the bushings. A worn bushings causes pin wear, and then the whole arm shifts. The catalog even includes a note about serial number breaks: (SN 11257 and up) so you know the manual matches your machine.

Filters and Special Service Kits: Don’t Substitute

Page 5 lists all filters, with a separate line item for the Return Filter – 274912 on page 6. The Tools section on page 4 covers special service parts and kits. I’ve seen guys grab a hydraulic filter from a farm store because it threads on, but the bypass pressure spec is wrong. That’s a fast trip to a failed pump. The GEHL catalog gives you the exact GEHL part number. No cross-referencing, no guesswork. For the alternator and starter (pages 62-63), you get the OEM replacement numbers. The decals section (pages 46-49) helps if you need safety labels for a rebuild or repaint. That’s attention to detail.

Why Aftermarket Parts Catalogs Cost You Money

I don’t trust aftermarket documentation on principle. This manual is a genuine GEHL publication, Form No. 918414, Revision A, June 2010. It’s printed in the USA. The Introduction page explicitly states: “Use only genuine GEHL service parts.” The copyright is © 2010 Gehl Company. If you access a scan from a site that says “compatible” but shows a different model or an earlier revision, you’re rolling dice with your machine. The 2010 Parts Catalog covers exactly the AL 140 from serial 11257 up. Not an earlier run, not a different loader. If you need the operators manual for other Gehl loaders, check out the GEHL AL 140 to AL 540 Operators Manual – Factory Specs for Articulated Loaders. For skid-steer models, the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog and GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs are also factory-verified.

Does this manual include wiring diagrams?

No. This is a parts catalog, not a service or electrical manual. The Electrical section (pages 18-22) covers fuses, battery disconnect kit, backup alarm kit, and block heater kit with part numbers, but no schematics. For wiring, get the corresponding service manual.

What about torque values for the cylinder head?

Standard fastener torque values are on the inside back cover. The engine section shows parts for the cylinder head and cover on page 55, but you’ll need the service manual for specific head bolt torque sequence and angle. This catalog gives you the part numbers for head gaskets and bolts.

Are part numbers still current?

GEHL updates part numbers. This manual reflects the 2010 revision. Some parts may have been superseded. Always verify with your dealer using the serial number. But the manual gives you a solid starting point so you don’t order blind.

Can I use this for an AL 140 with a serial number before 11257?

No. The manual explicitly states it covers SN 11257 and up. Earlier machines have different components. Order the manual for your specific serial number range.

Stop calling the dealer with a vague description or relying on a pirated PDF that shows parts for a different model. Access the Factory Manual. Get the 100-page GEHL AL 140 2010 Parts Catalog with verified part numbers and diagrams. Your time on the bench is worth more than the cost of the manual. Access the Factory Manual now and keep it on your tablet or printed. You’ll thank yourself the next time you need a steering cylinder seal kit at 5 p.m. on a Friday.
