GEHL 1500 Parts Catalog – Factory-Sourced Part Numbers for the RB1500A Baler

If you’ve ever had a baler down because you ordered a bearing that looked right but wasn’t, you already know the cost of guessing. That’s why you need the GEHL 1500 Parts Catalog – not a reprint, not a generic list, but the actual 34-page OEM document GEHL released for the RB1500A. I’ve seen guys spend a whole afternoon chasing a part number from a worn tag. This manual kills that waste.

Get the Right Part Number the First Time

Every page in this catalog comes from Gehl’s own engineering files. The Hardware Notice on page 2 tells you all bolts are Grade 5 cadmium plated unless specified otherwise. Hex lock nuts are Grade B, hex nuts for other bolts are Grade A. That matters when you’re torquing a bolt on the frame or the pick-up. Use a lower grade and you’re asking for a sheared head at 540 PTO rpm. The catalog gives you the exact part number for every nut, bolt, and washer, keyed to exploded views that show where each piece lands.

8 Major Assemblies Covered in This Parts Catalog

You get the Frame (pages 3-5) with all the plates, brackets, and hardware. PTO and Drawbar (pages 6-7) covers the driveline connection. Pick-up (pages 8-9) includes tines, cam track, and bearings. Rear Gate (pages 10-11) – latches, cylinders, and pivot pins. Upper and Lower Rollers (pages 12-15) are critical for bale density – you’ll find the right roller, bearing, and seal part numbers. Twine Box and Wrap (page 16) lists the twine arms and cutting mechanism. The Transmission (page 17) covers gears, shafts, and seals. Hydraulic Cylinder and Valve (page 18) – that’s where most leaks happen, and you get the seal kit numbers and valve body components. Accessories (pages 19-22) include options like a bale kicker. Universal Drives (page 23) covers the driveline cross and bearing kit. Hitch Jack (page 24) for the tongue. Even the Decal Locations (pages 25-27) are diagrammed so you can order replacement decals for safety warnings.

GEHL 1500 Parts Catalog – Hardware Grades and Bolt Specs

Right there on page 2 it says: all bolts in the parts lists are Grade 5 cadmium plated unless otherwise noted. I’ve seen aftermarket catalogs call out a Grade 2 for a frame mount that should be Grade 5 – that’s a liability. This manual also explains the abbreviations: HN for hex nut, LW for lock washer, ILW for internal tooth lock washer. You see “NF” for National Fine thread, “S-L” for self-locking. If you don’t know what that means, the manual tells you. No guesswork. When you’re rebuilding a baler in your shop, you need those thread pitches right or you’ll strip a casting.

Does This Manual Cover the Transmission and Hydraulics?

It does. Transmission on page 17 gives you the gear, bearing, and seal part numbers for the main drive. The Hydraulic Cylinder and Valve on page 18 are both covered – you get the cylinder seal kit number and the valve spool and body parts. I’ve had guys ask if they can use a generic o-ring from the farm store. The answer is no if you want it to hold pressure. The manual lists the exact o-ring dimensions and material. The Hydraulic Valve section includes the relief valve cartridge and the fittings. You need those part numbers to order from Gehl or cross-reference to a quality aftermarket supplier. Also note the PTO and Drawbar section (pages 6-7) includes the driveline clutch and shear bolt. That’s safety-critical – get the right shear bolt rating.

Why an OEM Parts Catalog Beats Aftermarket Lists

Aftermarket parts lists often skip revisions. This manual includes the serial number break – it says “Used before Serial No. 5712” for the frame section. That means you need to check your baler’s serial number plate, located under the top channel near the left frame assembly (page 2 tells you). If you order parts from a generic catalog, you might get the wrong frame plate because the design changed. GEHL also reserves the right to make changes without obligation – so you need the latest factory listing. This is the real thing, not a copy lifted from a scanned third-party site. If you want to understand diesel engine basics that drive your tractor, [LINK_ID_EXT_0] will help you with the fundamentals. But for the baler itself, this parts catalog is the source.

Does this manual include torque specs for bolts?

No. This is a parts catalog, not a service manual. It lists hardware grade (Grade 5) and lock nut class, but torque values are not given. For assembly torque, you need the GEHL service manual.

What serial numbers does this cover?

The frame section shows “Used before Serial No. 5712.” The catalog covers RB1500A balers with that serial number break. Check your serial plate under the top channel, center column of the left frame assembly.

How do I find which part I need if I don’t see it in the illustration?

Use the Numerical Index on pages 28-30. If you have a worn part with a number, look it up there to find the page and reference number. If the number is missing, measure the part and compare to the exploded view dimensions.

Is this the same as the service manual?

No. This is the Parts Catalog (34 pages). The service manual contains repair procedures, tolerances, and hydraulic pressures. You need both to do a complete rebuild. For more on diesel engine basics that apply to your tractor, see [LINK_ID_EXT_1] to understand the power source.

If you’re tired of chasing wrong parts and want to get your RB1500A back in the field, this catalog is what you need. Access the Factory Manual – it’s the same PDF Gehl dealers use. You get the exact part numbers, exploded views, and hardware specs. Stop guessing. Get the OEM data.
