GEHL AL140, AL240, AL340 2011 Service Manual – What You Get

You have a GEHL loader in your bay—AL140, AL240, or AL340—and you need to crack open the engine or sort out a hydraulic leak. The aftermarket PDF you found online gives you generic torque values that don’t match the factory fasteners. That’s how head gaskets fail and pumps get noisy. I’ve seen it too many times. What you need is the actual 2011 GEHL factory service manual, 360 pages of OEM documentation that tells you exactly how the machine was built, what fluids it takes, and what torque to pull those bolts to. No guesswork, no condensed reprints.

Mandatory Safety Shutdown Procedure – Chapter 2

Before you turn a wrench, Chapter 2 of this Service Manual lays out the mandatory safety shutdown procedure. It’s three lines long but skipping it has cost shops downtime and injuries. The manual covers battery hazards, fire prevention, and crystalline silica exposure when you grind or weld near the loader. Page 4 has the 2-Post ROPS/FOPS warning—read that before you lift the cab. Safety decals are diagrammed on page 9, part numbers included. You don’t guess what warning sticker goes where; the manual identifies it.

Fluid Capacities and Lubricants – Chapter 3 Specs

Fluid capacities for the hydraulic system, engine oil, and coolant are listed on page 11 in both SAE and metric, but the manual uses Imperial units as you’d expect for a North American machine. The AL240 takes 14.5 quarts of engine oil; the AL340 takes 17.2. Gear oil for the drive axles is spelled out by viscosity grade. If you mix in a wrong lube, the manual tells you the exact spec—no guesswork. Dimensions for the AL100 and AL300 series are on pages 13–15, critical for fitting the loader into a transport trailer or into a tight shop bay.

Engine, Hydraulics, Electrical System Specs

Page 19 aggregates the engine specs, hydraulic pressures, and electrical system ratings. The charge pressure for the hydrostatic drive? Not listed in the excerpt, but the chapter is there. The manual details the hydraulic pump flow rates for each model—AL140, AL240, AL340—and the relief valve settings. That’s the kind of data you need when you’re rebuilding a control valve or swapping a pump. The wiring diagrams are in the later chapters; the manual’s table of contents shows a full electrical system section.

Who Should Buy This Manual? Real-World Fit

Beginners working on a farm AL240 will appreciate the step-by-step removal procedures, but the manual assumes you already know how to use a torque wrench and a multimeter. You need to be comfortable reading wiring schematics and supporting the loader safely with jack stands. The manual is written for a technician who has done a few repairs but wants factory specs—no fluff, no hand-holding on what a bolt looks like. If you’re a home garage enthusiast with a AL340 that has a cooling issue, this manual gives you the fan belt tension and coolant capacity to fix it right the first time.

Source Authenticity: OEM vs Aftermarket

Other sellers reprint the gearbox section from a different loader and slap a GEHL cover on it. This is the original 2011 factory print with form number 918274, revision B. The table of contents matches what GEHL issued to its dealers. You get the same document a dealership tech would pull up on their shop computer. Aftermarket manuals often skip the safety decal diagrams or consolidate dimensions into one table that doesn’t differentiate the AL100 from the AL300 series. This manual keeps each model’s data separate. That matters when you’re ordering the correct belly pan or checking rollover stability criteria.

FAQ

Does this manual cover the AL340 engine rebuild completely?

It covers the engine section under Chapter 3 – Specifications and the overhaul procedures in later chapters, but the specific page numbers for torque values are in the engine section. If you need main bearing cap torque, it’s there.

Can I use this manual for the AL140 if I own an AL240?

No. The AL140 is a different series with different dimensions, fluid capacities, and hydraulic pressures. The manual includes separate data for each model, but you cannot swap the specs. Buy the manual for your exact model.

You’ve read enough. You know the difference between a generic online PDF and the real OEM document. This is the 360-page factory manual for the GEHL AL140, AL240, and AL340 articulated loaders.
