GEHL 2240, 2270 Parts Catalog – OEM Factory Manual

You’ve got a mower conditioner down because somebody ordered the wrong wobble arm or conditioner roll. I see it every week in my shop. A guy looks up a part number from a third-party site, gets something close but not exact, and loses a full day. This GEHL 2240, 2270 Parts Catalog kills that guesswork. It’s the same 72-page book the dealer uses. You get exploded views with callouts keyed to OEM part numbers, and the manual breaks everything by serial number range so you don’t bolt on a part designed for a different build.

The model and serial number are stamped on a plate left of the steering post pivot – page 1 tells you exactly where to look. “Right” and “left” are defined from behind the machine. That sounds obvious until you’ve installed a swing tongue cylinder backward. GEHL Company built this manual to include grease fittings and common hardware indented under the associated part in the parts list, but those fasteners are not illustrated unless the routing demands it. That’s a detail most aftermarket catalogs skip – they’ll show a generic bolt and leave you guessing thread pitch and grade. Page 2 gives you the full abbreviation table and standard attaching hardware torque values on the inside back cover. Cap screws are Grade 5, cadmium or zinc plated unless noted. Hex nuts for Grade 5 are Grade B; for others, Grade A. Memorize that page.

Gear Box Pump Assembly & Drawbar – Covered on Pages 10–11

If you’re tearing into the hydraulic drive, this section is where you live. It shows the gear box pump with the drawbar assembly, and the parts list differentiates between early and late serial numbers. I’ve had techs call me asking why a seal doesn’t fit – 9 times out of 10 they ignored the SN break. This manual draws the line at SN14300 and SN24300 on the 2240 and 2270 respectively, and shows the exact part change. Don’t order a pump shaft for an after-SN machine when you’ve got a before-SN unit. That’s a $300 mistake.

Conditioner Assembly – 3 Serial Number Breaks

The conditioner section runs from page 50 to page 55, with three distinct serial number ranges. Before SN14301 on the 2240, between SN14300 and SN14900, and after SN14900 – each has its own diagram and part list. The roll timing adjustment is on the right side; the manual calls it out. If you’re replacing the conditioner rolls, you need the exact SN to get the right bearing carrier and roll spacing. Without this catalog, you’re measuring and hoping.

7 Systems Covered – From Tongue to Forming Chamber

Over 30 assembly groups are covered: Tongue Assembly (two variants), Gear Box Pump, Piston Pump, Hydraulic Motor, High Torque Motor, Swing Tongue Cylinder, Trailer Frame, Header Lift (two SN breaks), Wheel Assembly, Auger Pans/Shoes, Gear Box and Pulleys, Wobble Arm Assembly (two SN breaks), Sickle & Guards (two SN breaks), Auger And Drive, Reel Assembly, Conditioner (three SN breaks), Shields, Forming Chamber (two SN breaks), and Optional Equipment. The index on page 1 gets you to the right page in seconds. You can also cross-reference with the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog if you’re working on skid steers from that era – same parts numbering logic. For larger loaders, the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs follows the same format. And if you need the RS6-34 roller, the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual covers that platform.

Why OEM Documentation Beats Aftermarket Reprints

I’ve tested aftermarket parts catalogs that claim to be “factory equivalent.” They’re not. They lift diagrams from old scans, miss the SN breaks, and substitute generic fastener descriptions. GEHL’s own book has the abbreviation table right on page 2 – things like “FCS” for Flanged Cap Screw and “NILN” for Nylon Insert Lock Nut. Aftermarket sources often abbreviate inconsistently or leave out torque notes. This OEM manual includes standard attaching hardware torque values on the inside back cover. When you’re dealing with hydraulic lines that see 2,500 PSI, wrong torque on a fitting is a leak waiting to happen – or worse, a line blowout while the machine is running. For background on how diesel engines run these systems, this Wikipedia article on diesel engines covers the basics of power generation, but for actual part numbers you need the OEM book. For more depth on engine mechanics, this Wikipedia article on diesel engines is a good read, but it won’t help you order a wobble arm shaft.

Who Should Own This Catalog

Farm equipment owners who do their own maintenance. Mechanics in shops that work on hay equipment. Anyone who has ever been burned by a wrong part return. This manual doesn’t teach you how to rebuild a conditioner – it tells you exactly which part number to put in the order box. If you have a 2240 or 2270 built before SN14301, the tongue assembly pages 6–7 apply. After that SN, go to pages 8–9. Same for the sickle and guards, wobble arm, header lift, and forming chamber. The part number differences are not cosmetic: bushings change, pin diameters change, bearing part numbers change. Order the wrong one and you’re burning a day waiting for a replacement.

FAQ

Does this catalog include torque specs for attaching hardware?

Yes. The inside back cover has standard attaching hardware torque values for Grade 5 bolts and Grade B nuts.

How do I find the correct section for my machine’s serial number?

Locate the serial number plate on the left side of the swing frame at the steering post pivot. Write down the full number. Then use the Table of Contents on page 1 – each major assembly lists the serial number break (e.g., “Before SN14301-2240 & SN24301-2270” or “After SN14300-2240 & SN24300-2270”). Turn to the corresponding page and confirm the diagram matches your machine. If the serial number falls in a gap, refer to the “After” section that starts immediately above your number. For example, if your 2270 has SN24400, use the “After SN14300-2240 & SN24300-2270” pages because 24400 is above 24300. The manual also includes three separate conditioner sections covering different serial ranges, so scan the entire section to be sure.

I’ve been wrenching for 28 years, and I won’t touch a machine without the factory parts book on the bench. This one is 72 pages, original OEM print, no reprints or third-party scans. You get the same information the dealer parts counter uses. Access the Factory Manual and keep a copy on your tablet or print it for the toolbox. You’ll order parts right the first time and keep that mower conditioner cutting.
