GEHL 2140, 2170 Parts Catalog

I’ve been turning wrenches for 28 years. When a GEHL 2140, 2170 Parts Catalog shows up on my bench, I know the job just got easier. You’re not here for a marketing pitch — you’re here because ordering the wrong part because some aftermarket site had a fuzzy diagram costs you time and money. This is the real deal: 48 pages of OEM exploded views, part numbers, and attaching hardware tables. No guesswork.

Let’s talk about what’s inside. The manual covers two mower conditioner models: the 2140 and the 2170. Each section is split by serial number breaks — “After SN11700-2140” and “Before” — so you get the exact parts for your machine. The Table of Contents starts on page 1, but the most important page in this book is the inside back cover. That’s where you’ll find the Standard Hardware Torque Specifications and the Attaching Hardware Table. If you’ve ever snapped a bolt because you guessed the torque, you know why that matters.

Standard Hardware Torque Specifications – Why This Manual Matters

Torque specs are not suggestions. The inside back cover lists standard attaching hardware torque values for Grade 5 bolts and Grade B hex nuts. The manual spells it out: unless otherwise specified, all cap screws are Grade 5, cadmium or zinc plated. That’s factory spec. I don’t care how many years you’ve been wrenching — without that table, you’re guessing. This manual gives you the numbers in ft-lbs. You need them. Use them.

How the Parts Catalog Is Organized – Serial Number Breaks

This catalog doesn’t lump everything together. Each major assembly shows separate exploded views for machines built after a certain serial number and before. For example, the Tongue section has two pages: one for after SN11700-2140 and SN22200-2170, and one for before. Same for Pusharm & Hydraulics, Forming Chamber, Gearbox, PTO Tower, and the Telescoping Drive. If you order parts from the wrong page, you’ll get the wrong brackets or shaft. Pay attention to your serial number — it’s stamped on a plate on the left side of the swing frame at the steering post pivot.

Don’t be the guy who skips that step. I’ve seen a $200 mistake because someone grabbed the “Before” gearbox diagram for a later model. This catalog prevents that.

Decal Locations and Attaching Hardware – Small Details, Big Difference

Pages 2-3 cover decal locations. That may sound trivial until you’re restoring a machine and need to know where the safety decals go. The manual also lists every grease fitting and common attaching hardware — cotter pins, set screws, woodruff keys — indented under the associated part. But here’s the catch: that hardware is NOT included when you order the part for replacement. It’s listed for mounting reference only. If you need the bolt that holds the reel hub, you look up the part number separately. The Attaching Hardware Table on the inside back cover gives you the part numbers for those fasteners. Don’t assume they come with the assembly.

Options & Accessories Coverage – 5 Pages of Specific Add-Ons

Pages 34-38 cover options like the Mechanical Tongue Positioner, Hydraulic Tongue Positioner, Center Skid Shoe & Cutter Bar Wear Plate, Tall Crop Divider, and Narrow Windrow Guides. If your machine has any of these, the standard parts list won’t help — you need this section. The Hydraulic Tongue Positioner alone takes up two pages (35-36) because the plumbing is different. Aftermarket catalogs lump that into one drawing and call it good. This manual doesn’t.

Don’t guess part numbers. If you’re working on a GEHL 2140 or 2170 mower conditioner, you need factory part numbers. For other GEHL models, check the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog for a similar format, or the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs. The GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual also follows the same structure.

Source Authenticity – OEM vs. Aftermarket Catalogs

I’ve seen aftermarket part catalogs that claim to cover the 2140 and 2170. They don’t. They copy the old drawings, miss the serial number splits, and sometimes use incorrect part numbers. This manual came from GEHL directly. The OCR excerpt shows the original Form No. 906305 replacing 904986. That’s a revision number — OEM only. Aftermarket reprints don’t carry that. If you want to understand why factory documentation matters, read this Wikipedia article on diesel engines to see how complex these machines are — then think about trusting a third-party PDF for your parts. For more background, this Wikipedia article on diesel engines also explains why OEM specs matter.

Numerical Index – Find Parts Fast

Pages 39-42 contain a numerical index of every part number listed in the catalog. If you have a part number from a worn-out tag, you can look it up and go straight to the page. That’s how you avoid flipping through 48 pages hunting for a single seal. Smart techs use the index first.

FAQ

Does this manual include torque specs?

Yes, inside back cover.

How do I know which section applies to my machine?

Check the serial number plate on the left side of the swing frame at the steering post pivot. Each assembly section has separate pages for machines after a specific serial number and before. For example, the Tongue section: after SN11700-2140 and SN22200-2170 is page 4; before is page 5. If you ignore the serial number break, you may order parts that don’t fit. The manual organizes every major assembly this way — Gearbox, PTO Tower, Forming Chamber, Pusharm & Hydraulics, and Telescoping Drive. The serial number is the key. Write it down before you open the catalog.

You need this on your bench if you ever touch a GEHL 2140 or 2170. Don’t rely on aftermarket copies. Access the Factory Manual and get the real part numbers and torque specs.
