GEHL 100 Parts Catalog – Factory OEM for Mix-All

If you’re ordering parts for a GEHL 100 Parts Catalog machine and you’re not using the factory catalog, you’re gambling with downtime. I’ve seen too many guys pull a part number off a third-party site, get the wrong bearing, and end up with the unit torn apart for an extra day. This 76-page book—the GEHL 100 Parts Catalog—is what GEHL shipped to dealers. It’s the same one we keep in the shop at San Antonio, laminated and grease-stained, because it works.

Know Which Transmission Parts Fit

The transmission section starts on page 5. If you’ve ever tried to cross-reference a GEHL transmission from a generic parts list, you know it’s a losing game. This catalog shows every gear, shaft, seal, and bearing with the factory number. Page 5 covers the transmission assembly. No guessing if the clutch hub changed between serial numbers—it’s laid out with the serial break notes. You want the input shaft for a machine before SN8107? It’s on page 12 for the unloading conveyor, but the transmission itself is page 5. That’s the kind of detail that keeps you from ordering the wrong part twice.

76 Pages of OEM Part Numbers and Exploded Views

Every chapter in this GEHL 100 Parts Catalog is an exploded-view drawing with a numbered parts list. From the frame and axles (pages 6–7) to the hydraulic components (pages 38–39), you get the exact bolt grade and finish. The manual tells you that unless specified, cap screws are Grade 5, zinc-plated. The attaching hardware table on the inside back cover gives you the torque values for standard fasteners. That’s not in any aftermarket PDF I’ve seen.

Decal Locations: Why They Matter

Pages 2–4 cover decal locations. If you’re rebuilding a used GEHL 100 and the safety decals are missing, you need to know where they go for inspection and liability. The catalog shows each decal by part number. Skip this and you might have a machine that fails a safety audit—or worse, an operator who doesn’t see the pinch-point warning. I’ve had customers call asking why their rental yard rejected the machine. It’s because the decals weren’t placed per the factory diagram.

3 Reasons to Use the Factory Parts Catalog Instead of Aftermarket

First, aftermarket catalogs re-draw the parts and often miss the subtle revisions. This manual includes a “Replaces” note on the cover (Form 903477 replaces 903210). Second, the hardware tables are explicit: lock washers, plain washers, nut grades. See this Wikipedia article on diesel engines for understanding thread standards, but for the GEHL 100, the catalog lists UNC and NF threads where they differ. Third, the numerical index on pages 64–69 lets you look up any part number and find its page in seconds. Try that with a scanned copy from a third-party site.

Transmission and Drivetrain Breakdown – Page 5 and Beyond

The Transmission section is the heart of this machine. GEHL used a PTO-driven gearbox with a clutch and various reduction stages. The parts list includes the shift forks, bearings, and the output shaft. If you need the PTO stub shaft, it’s called out with the correct keyway dimensions. On page 5, the transmission is broken into sub-assemblies—no guessing if the snap ring is included with the shaft or sold separately. It’s listed indented under the parent part.

Don’t forget the implement drive line and guard on pages 20–21. Those U-joints and shear pins are specific to the 100 model. A generic U-joint might fit but fail at the wrong torque. The catalog gives you the part number for the complete assembly and the individual components. That’s how you avoid the “I’ll just replace the cross” trap that leaves you stranded in the field.

What Does the 76-Page Catalog Cover?

Everything from the concentrate hopper (pages 10–11) to the hydraulic systems (self-contained pages 32–35, tractor-powered page 36). The options section (pages 40–53) includes the Swinging Auger Feeder (SAF) and Gravity Feeder (GF). There’s even a section for accessories like the molasses attachment (page 54) and the scale battery mounting kit (page 59). If you’re retrofitting a control box or an auxiliary remote control, those are on pages 58 and 63 respectively.

FAQ – Common Questions About the GEHL 100 Parts Catalog

Are the part numbers still current for a 1970s GEHL 100?

GEHL updated part numbers over the years, but this catalog uses the original factory numbers. If a part has been superseded, you’ll need to cross-reference with a current GEHL dealer. The catalog includes a “Replaces” note—Form 903477 replaces 903210—which tells you the revision.

Does it include torque specs for transmission bolts?

Yes. The inside back cover has a standard hardware torque table for Grade 5 bolts, which covers most fasteners on the transmission.

Can I use this catalog to identify parts for a different GEHL model?

No. This manual is exclusively for the GEHL 100 Mix-All. Some components may be shared with other models, but the exploded views and part numbers are model-specific.

How do I know which serial number breaks apply to my machine?

The catalog lists serial number breaks throughout, e.g., “Used Before SN8107” and “Used After SN8106”. Check the decal on the frame near the tank base—the manual tells you exactly where to find it on page 2 (Mr. Dealer section).

I’ve been turning wrenches for 28 years, and when a parts catalog shows you both the before and after serial breaks for a conveyor winch (pages 16–19), you know it’s the real thing. Don’t waste time with generic diagrams. Access the Factory Manual and get the exact part numbers that GEHL put on the assembly line. Your machine—and your wallet—will thank you.
