GEHL TR3038 Parts Catalog – Factory Parts Breakdown for Your Two-Row Attachment

You are looking for a specific part on your GEHL TR3038 two-row attachment. You pull an aftermarket parts diagram off the internet and find the bolt listed as “M12 x 1.75 – 45mm.” No grade. No torque value. That part number from a third-party site doesn’t match anything in your bin, and the head is rounded off because you guessed at the ft-lbs. That waste of time is exactly why I carry the OEM GEHL TR3038 Parts Catalog on my bench. Forty-two pages of factory-verified part numbers, exploded views with reference numbers, and—on the inside back cover—the standard hardware torque specifications you need before you tighten one fastener.

Frame & Jackshaft Drive – Where the Torque Starts

Page 4 shows the Frame & Jackshaft Drive assembly. Each cap screw and bolt in that section has a reference number tied to a parts list. The torque values for those fasteners are not scattered through the document; they are printed on the inside back cover. Standard torque for Grade 5 cap screws, in foot-pounds. No guesswork. If you skip that page and torque by feel, you will pull threads or snap a bolt. The catalog also marks wet applications with a teardrop symbol and the required torque in a hexagon right next to the part—so you know when Loctite or oil is needed.

Gatherer Drive: Exploded View vs. Aftermarket Garbage

Pages 16 through 19 cover the Gatherer Drive. The difference between this OEM catalog and a generic PDF is the level of detail: every chain, sprocket, and bearing is called out with a specific part number and an abbreviation key (e.g., CS for cap screw, FLN for flanged lock nut). The aftermarket stuff I have seen lists “assembly” and leaves you hunting for the internal bearings. Here, the carrier and rotor are broken down on pages 8–11, with separate items for each seal and spacer. If you need a rotor bearing for the TR3038, you get the factory number—not a cross-reference that might be wrong.

What the Torque Specs Mean for Your Build

Inside back cover. That is where you find the standard hardware torque table for Grade 5 bolts and Grade B hex nuts. I have seen guys skip that page and assume “tight enough” is good. On a two-row attachment running at PTO speed, a loose cap screw on the deflector (pages 26–27) can turn a harvesting day into a field repair. The catalog also notes that unless otherwise specified, all cap screws are Grade 5, cadmium or zinc plated. That matters when you are ordering replacements—grab a Grade 2 by mistake and you will be back in the shop.

7 Systems, 42 Pages – Why This Manual Exists

The table of contents lists seven major sections: Frame & Jackshaft Drive, Frames (Inner and Outer), Carrier & Rotor, Gatherer, Gatherer Drive, Partitions, Fenders, Deflector, Points, Covers, Stand, and Lubrication. That is the complete mechanical anatomy of the TR3038 attachment. Each section uses a reference number system with callouts to the parts list. If a part does not have a reference number, it is shown for reference only and is not sold separately—that detail alone saves you from ordering the wrong piece. The alphabetical index on page 35 and numerical index on pages 36–38 let you find any part number in seconds. No flipping through random pages.

OEM vs. Aftermarket: The Source Authenticity

This is a GEHL factory publication, Form No. 908014, replacing 904865. Printed in the U.S.A. The serial number plate location is stated: right side of the main frame next to the attachment stand. The manual uses “Right” and “Left” as viewed from behind the unit facing forward. Aftermarket catalogs often swap those directions or omit the orientation rule. I have caught aftermarket diagrams reversing the gatherer drive sprockets on the TR3038 because they mirrored the drawing. This catalog does not have that problem. Every part is keyed to the actual assembly sequence.

If you are working on other GEHL skid loaders or attachments, check the related manuals I keep on the shelf: GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog covers the compact loader range. For the larger chassis, see the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs. And if you need the RS6-34 rock saw attachment, the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual uses the same part-numbering system.

FAQ

Does this parts catalog include torque values?

Yes. The inside back cover lists standard hardware torque specifications in foot-pounds for Grade 5 cap screws and Grade B hex nuts. Certain parts also have a torque value printed inside a hexagon symbol next to the reference number.

Can I use this catalog for assembly or just ordering parts?

It is a parts catalog, not a service manual. You use it to identify correct part numbers and verify torque specs. For disassembly or rebuild procedures, you need the corresponding service manual. That said, the exploded views and fastener callouts are detailed enough that an experienced mechanic can follow the assembly order from the diagrams.

Stop wasting time with mismatched parts and second-guessed torque. Get the factory diagram that matches your machine serial number. Access the Factory Manual and put the right part on the first try.
