GEHL 1865 Parts Catalog

If you’ve ever ordered a replacement part for your GEHL 1865 round baler and ended up with the wrong cotter pin or a bolt that didn’t fit, you already know the headache. That’s why the OEM Parts Catalog exists – not a scanned copy, not a third-party rebuild, but the actual 52-page GEHL 1865 Parts Catalog from the factory. I’ve been turning wrenches for 28 years, and I’ll tell you flat: you cannot trust aftermarket parts lists. This booklet tells you exactly which grade 5 cap screw goes where, which flanged lock nut is required, and how to read the abbreviations so you don’t order a FHMS when you need a RHMS.

Abbreviations Decoded: Every Code on Page 2

Page 2 of this catalog lists every abbreviation used in the parts lists – from AR (As Required) to SOHSS (Socket Head Set Screw, Self-locking). You’ll see CS for Cap Screw, FHMS for Flat Head Machine Screw, and even WIO for Washer, Inside Outside. Without this reference, you could be hunting for a PN that doesn’t match the hardware you’re trying to order. The manual explains that common attaching hardware like cotter pins and set screws are indented below the associated part – they are NOT illustrated unless the routing is critical. That level of detail keeps you from over-ordering or missing a fastener that’s listed but not drawn.

Torque Specs on the Inside Back Cover

Standard attaching hardware torque values are printed on the inside back cover. This is the same table the factory repair shops use. If you’re bolting the drive line back together or torquing wheel hardware, you need those numbers. The catalog also specifies that unless noted, all cap screws are Grade 5, cadmium or zinc plated, and hex nuts for those are Grade B. That’s not a suggestion – that’s the OEM spec. Use a lower grade and you risk fastener failure. Use a higher grade and you might crack a casting. Stick to the book.

Right and Left Orientation – Don’t Guess

This manual defines “Right” and “Left” from a position standing behind the unit, facing the direction of travel. The universal drive and transmission are on the left side. That may sound obvious, but I’ve seen parts ordered backwards because someone read the diagram from the front. The catalog includes that orientation note in the introduction so every part callout lines up with your baler’s actual layout.

Ordering Parts: What You Need to Know

When you call for a part, you must specify the correct part number, full description, quantity, unit model number, and serial number. The serial number plate is located under the top channel near the center column of the left frame assembly. The catalog instructs you to find that tag and keep it handy. Also note the company policy: original tires are not sold as replacements – only wheel sets are available, and tire size info is called out with those sets. You buy the tires locally. That kind of manufacturer-specific policy saves you from ordering something that simply won’t ship.

this Wikipedia article on diesel engines covers the power unit that typically runs these balers, but inside this catalog you’ll get the actual hardware breakdown for the baler itself – belts, chains, rollers, bearings, and the twine system. For related equipment, see GEHL 1465, 1865 Operators Manual – Factory Specs for Round Balers and GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog for skid-steer loaders that might share hardware with your operation. GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs covers the larger loader family.

52 Pages of Factory Spec – Not a Reprint

This is the original GEHL service parts manual (Form No. 904114) for the 1865 variable chamber round baler. It’s a factory-issued document, not a reprint or a third-party compilation. Aftermarket books often skip the attaching hardware table or abbreviate the abbreviations section to save space. GEHL includes everything, including the note that replacement tires must be purchased locally and that hardware listed for mounting is not included when ordering the parent part. If you rely on a knock-off manual, you risk getting the wrong PN and losing a day of baling.

Does this manual include exploded-view diagrams?

It does not have full exploded-view illustrations for every assembly, but each parts list is grouped by sub-system (drive, pickup, bale chamber) and the hardware is indented under its associated part. The manual tells you which fasteners are illustrated versus those that are only listed in the text.

Can I use this catalog to order parts for a different GEHL baler?

No. This is specific to the 1865 model. The serial number plate location, orientation rules, and part numbers change between models. Order the correct catalog for your machine.

What about the torque values – are they listed for each individual bolt?

No. The inside back cover gives standard torque values for common fastener grades and sizes. Special torque requirements (like wheel lugs or PTO shaft bolts) are noted in the individual parts lists where applicable. Always check both locations before tightening.

Will this manual help me rebuild the baler step by step?

It’s a parts catalog, not a service manual. It helps you identify and order the correct components. For rebuild procedures, you need the GEHL 1865 Service Manual. The parts catalog complements that repair guide by giving you the exact fastener grades and part numbers the factory specs.

Access the Factory Manual and keep it in your shop binder next to the baler. When you need a flanged lock nut or a specific Woodruff key, you’ll have the exact GEHL part number in front of you – not a guess, not a reprint, but the real 52-page document the factory put together for this machine.
