GEHL AL 340 2010 Parts Catalog – Factory Bolts, Filters, and Hydraulics

If you are wrenching on a GEHL AL 340 articulated loader built after serial number 31365, you need the actual 2010 Parts Catalog – not a scan of something that claims to be close. I have seen too many guys order a filter by guessing the cross‑reference and end up with a bypass valve that doesn’t open at the right pressure. This book, 134 pages long, is the only source that lists the exact GEHL part numbers for every nut, seal, and hydraulic line on that machine.

134 Pages of OEM Parts Data for the AL 340

This manual breaks the loader into 12 major sections – Tools & Filters, Cab, Chassis, Controls, Axles, Lift Arm, Hydraulics, Cylinders, Attachments, and more. Each section starts with an exploded‑view illustration that shows how parts nest together. The table of contents alone takes up two pages (i and I) because there are that many sub‑assemblies. For example, the Cab chapter alone has 11 sub‑sections: doors, wipers, heater, mirrors, steering column, upper/lower platforms, isolation mats, ROPS two‑post and four‑post, work lights, strobe kits, and radio kits. That level of detail saves you from ordering a mirror bracket that fits a different cab variant.

The hydraulic section runs from page 50 to page 63 and covers the tank, drive pump (Axial Piston Pump – 273011), motor (273010), power steering, control valve, auxiliary valve, and each cylinder – lift, tilt, steering, Power‑A‑Tach, and Quick‑Attach. Every seal kit is called out. Page 52 shows the hydraulic tank with the return filter (part 274912) and its exact O‑ring size. I have had three different parts counter guys try to sell me a generic return filter for that machine – they were all wrong. This catalog keeps you from wasting a day.

Torque Specs and Fastener Grades: Page 2 & Inside Back Cover

Inside the front pages you get the standard attaching hardware torque table – inch and metric. The intro page (page 2) states explicitly: “Unless otherwise specified, all cap screws, nuts, and bolts are Grade 8.8, cadmium or zinc plated.” Metric torque values are given in Newton‑meters, and the manual tells you to multiply by 0.738 to get foot‑pounds. If you rely on a generic torque chart, you risk stretching a Grade 8.8 bolt in an axle mount. That’s a lawsuit waiting to happen. The inside back cover has the full torque table – I keep that page scanned and laminated in my toolbox.

Audience Fit: Who Needs a Factory Parts Catalog?

This is for the guy who owns a GEHL AL 340 and plans to keep it running five, ten more years. It is also for the shop that services a mixed fleet of compact loaders and needs to match the exact piston pump part number without disassembling the whole unit. The parts catalog does not contain step‑by‑step repair procedures – you want the service manual for that – but it gives you the part numbers and exploded views that let you order the correct components before you tear down. Home garage guys: if you are rebuilding the hydraulic drive, you need the part numbers for the shaft seals and wear plates on the axial piston motor. This book has them.

Source Validity: OEM vs. Aftermarket Parts Lists

I will not use aftermarket parts catalogs for a GEHL machine. They often omit serial number breaks or substitute generic part numbers that “should work.” The OEM catalog from GEHL Company (Form No. 918413, Revision A, June 2010) includes serial‑number exceptions like “(SN 999 and before except 997)” and “(SN 2001 and up including 1996).” That level of precision is impossible in a third‑party compilation. If you order a steering cylinder seal kit for an AL 340 with serial number above 31365, the OEM book shows the correct kit. The aftermarket book might give you the one for the earlier series – then you have a leak and down time. Buy the factory document.

3 Related Manuals for GEHL Loaders

If you work on multiple GEHL models, pair this parts catalog with the GEHL AL 140 to AL 540 Operators Manual – Factory Specs for Articulated Loaders. For skid‑steer guys, the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog covers the 4600‑series machines. Need parts for the larger skid‑steers? Grab the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs.

Does this parts catalog include torque specs for every bolt?

Yes, for standard fasteners. The inside back cover has the standard torque table. Specific torque values for critical joints (like axle mounting bolts) are called out in the individual part illustrations.

Will this work for an AL 340 built before serial number 31365?

No. The catalog explicitly states it covers SN 31365 and up. Earlier machines used different hydraulic pump and motor part numbers. You need the pre‑2010 parts manual.

How do I interpret the serial number exceptions in this catalog?

Page 2 explains the notation. For example, “(SN 1000 – 2000 except 1996 including 997)” means you include SN 997 but exclude 1996. Read that page carefully before ordering parts.

Can I use this to rebuild the axial piston pump?

It provides the part numbers and an exploded view on page 54, but it is not a service manual. You need the GEHL AL 340 service manual for the rebuild procedure. The parts catalog ensures you order the correct seal kit and wear plate set.

You have two choices: keep guessing at part numbers and waste hours returning wrong filters, or get the factory documentation that lists every component by GEHL’s own part designation. I have been turning wrenches for 28 years, and I trust a manual that tells me which grade 8.8 bolt goes into the front frame mount. Access the Factory Manual that matches your AL 340’s serial number – it is the only way to be sure the part you order is the part that fits.
