GEHL 135 Parts Catalog

You’ve got a GEHL 135 Mix-All on the lift and you’re hunting down a part number for that conveyor winch or the mill cylinder. Aftermarket catalogs will give you a generic drawing and a “similar to” number. That costs you time and money when the bolt pitch or the hydraulic fitting thread is off. I’ve seen guys lose half a day because a dealer sent the wrong drive sprocket. This GEHL 135 Parts Catalog is the factory document – 84 pages of original OEM part numbers, exploded diagrams, and fastener callouts. No abbreviations you have to guess at – they give you a full abbreviation table on page 2. If you need a hexagon tap bolt or a flanged lock nut, you’ll find the exact GEHL part number.

Decal Locations and Serial Number Identification

Before you order anything, you need to know which revision your machine is. This manual starts with decal locations (pages 2–5) and tells you exactly where to find the model and serial number decal: on the frame member at the rear, base of the tank. The Swinging Auger Feeder and Power Bale Feeder have their own decals. If you skip this step and order a part for the wrong serial number range, you’ll end up with a conveyor winch that doesn’t fit. The manual separates components by serial number breaks – “Used Before SN4136” and “Used After SN4135” – so you get the correct assembly.

Frame & Axles to Unloading Conveyor – 7 Major Assemblies

From frame and axles (page 6) all the way through concentrate hopper, tank discharge conveyor, implement drive, and unloading conveyor, each section has its own exploded view and parts list. The Unloading Conveyor section is split into two variants depending on serial number – something an aftermarket catalog won’t tell you. Each drawing shows the fastener location and calls out the thread type: UNC, NF, NPT. Need a replacement wheel set? The manual states that GEHL does not sell individual tires – you buy the wheel set, and tire size information is included with that set so you can source the rubber locally. That’s the kind of detail that keeps you from ordering a rim with the wrong bolt pattern.

Hydraulic Components: Valves, Regulators, Motors

The hydraulic section (pages 30–31) covers valves, regulator, and motors. If you’re troubleshooting a slow conveyor or a weak discharge, you need the exact part numbers for the hydraulic motor and the regulator assembly. The manual also separates the self-contained hydraulic system from the tractor-powered system (pages 32–34). That’s a critical distinction. A self-contained system uses its own pump and reservoir; a tractor-powered system runs off the tractor’s hydraulics. The fittings and hoses are different. Using the wrong O-ring or fitting can cause a leak that dumps hydraulic fluid onto the ground – then you’re dealing with cleanup and a safety hazard. The part numbers here are factory-correct.

What the Abbreviation Table Means for Your Repair

Page 2 of this catalog contains a table of abbreviations that covers every fastener type you’ll see in the parts lists: CS (cap screw), HSH (hexagon socket head), SHSS (socket head set screw), FLN (flanged lock nut), NILN (nylon-insert lock nut). If you see “HTB” in a parts list, that’s a hexagon tap bolt – not a cap screw. That distinction matters when you’re ordering a replacement bolt for the mill cylinder or the transmission mount. The manual also lists abbreviations for each feeder type: GF (gravity feeder), FR (feed roll), SAF (swinging auger feeder), PBF (power bale feeder). If you need parts for the power bale feeder, turn to the Options section (page 35 and beyond).

Options Section – PBF Hydraulics and Cylinder Supports

This parts catalog devotes pages 35–57 to options, including PBF hydraulics and cylinder supports. The PBF (Power Bale Feeder) hydraulics section has its own part numbers for hoses, cylinders, and valves. The cylinder supports are separate – if you’re adding a bale feeder to a machine that didn’t have one, you’ll need those brackets. The manual also covers the small grain auger (SGA) and swinging auger feeder attachments. Each option is broken down by serial number range. Without this, you’d be cross-referencing online forums and hoping the parts match. With the factory manual, you get the GEHL part number and the fastener list. That’s the difference between a one-hour fix and a three-day headache.

3 Reasons to Choose OEM Documentation Over Aftermarket

First: the part numbers are GEHL-verified. When you order from a dealer, you read them the factory number – they pull the right bearing, seal, or hydraulic motor. Second: the exploded views show the order of assembly. You can see if a snap ring goes inside the housing or outside, and which spacer sits between the bearings. Third: the manual includes the “attaching hardware” notes – fasteners that are included with the main part but not sold separately. Aftermarket catalogs often list hardware as a separate line item, leading to double-ordering. OEM catalogs tell you exactly what comes with the part and what you need to order separately.

Does the GEHL 135 Parts Catalog include torque specifications?

No.

Can I use this catalog to identify parts for a Mix-All with serial number above 4136?

The manual covers both serial number ranges – “Used Before SN4136” and “Used After SN4135” – for the conveyor winch and unloading conveyor. For the conveyor drive, the split is at SN4335/4336. Check the decal on your machine, then go to the appropriate page. If your machine falls outside those ranges, confirm with GEHL. The catalog also includes a note that GEHL Company reserves the right to make design changes without obligation – so if your machine is a late production run with updated components, the part numbers listed for the earlier range may not match. Always verify against your serial number and call the dealer if you’re unsure. The 84 pages are organized by assembly, not by serial number, so you need to read the headings carefully.

If you’re pulling a mill cylinder or replacing a conveyor drive sprocket on a GEHL 135, you need the original part numbers and the serial-number-specific assemblies. Aftermarket reprints skip the detail that saves you from ordering the wrong hydraulic motor or missing a critical snap ring.
