GEHL BU910 Parts Catalog – Factory OEM Parts Breakdown for the Forage Box

If you’re working on a GEHL BU910 forage box and need to order parts, you don’t have time to guess part numbers. Aftermarket parts listings are garbage—they mix up serial number breaks and leave you with the wrong bolt. This 36-page Parts Catalog is the original factory document from GEHL. It shows every nut, washer, decal, and major assembly. You get exploded diagrams with callouts and a numerical index for cross-referencing. No substitute.

Decal locations on page 3 show exactly where each safety label goes. The set number 900919 includes 10 decals from the universal joint instructions to the grease arrow. Surface prep instructions are given—grease and dirt ruin adhesion.

Decal Locations and Assembly Orientation – Page 3

Right and left are determined standing at the rear of the unit looking toward travel direction. The conveyor is on the front and discharges from the left side. If you ignore this orientation, you’ll order left-hand parts for the right side. The manual spells it out in the introduction on page 2.

What Parts Are Covered in This Catalog?

Beater (pages 4-5) gives you the complete beater drum and tooth assembly. Third Beater on page 6 handles the secondary beater. Unloading Conveyor on page 7 covers the chain and slats. Feeder pages 8-9 include the feed rolls and stripper plates. Hopper sections (pages 10-13) are split by serial number because the geometry changed after 7750—buying the wrong hopper side means the conveyor doesn’t fit. Clutch and Drive (pages 14-17) have the same split. Transmission (pages 18-19) shows the gearbox internals. Conveyor Extension (20-21), Rear Door Mounting (22-23), Rear Unloader (24-25), Truck Drive (26), Accessories (27-28), Universal Drives (29), Box Panels (30-31). The numerical index on pages 32-34 lists every part number alphabetically. That index alone saves you from flipping through 30 pages looking for a single bolt.

Use the Numerical Index for Cross-Referencing

After you find the part number on the exploded view, cross-check it in the index. The index points you to the exact page. No flipping through random sections. This is standard for factory manuals—aftermarket copies leave out the index.

Transmission Breakdown: Pages 18-19

The transmission section covers gear and shaft assemblies with individual part callouts. If you need a gear for the drive train, you’ll find the exact part number and quantity required. Common hardware like hex nuts and lock washers are listed but not illustrated—read the note on page 2 about ordering spares.

3 Sections That Save You Ordering the Wrong Part

First, the Hopper is split into two sections based on serial number: after 7750 and before 7751. Second, the Clutch and Drive has the same split. Ordering the wrong clutch hub because you didn’t check the serial plate is an expensive mistake. Third, the Decal set is ordered as a complete set—individual decals are not sold separately per the manual. Pay attention to the serial number plate on the right outside header.

Source Authenticity: Factory OEM vs Aftermarket

This is the original GEHL document (Form No. 901438). Aftermarket parts catalogs often re-label parts or skip the serial number splits. I’ve seen aftermarket diagrams mislabel the beater direction. This factory version has the correct exploded views and part numbers that match GEHL’s inventory. If you want to understand how the diesel power unit interfaces with the driveline, you can also check this Wikipedia article on diesel engines for general knowledge, but for parts ordering stick with the OEM spec.

Another resource for skid steer parts is the this Wikipedia article on diesel engines—but again, that’s background, not parts lookup.

Frequently Asked Questions

Does this manual include torque specs for assembly?

No. This is a parts catalog, not a service manual. Torque values are not listed. You’ll need the service manual for that.

Can I use this catalog for a GEHL BU910 built after 1990?

The catalog does not specify a publication year. However, it covers the BU910 model with serial number splits for hopper and clutch at 7750/7751. If your machine’s serial number is above 7750, use the “After Serial No. 7750” sections. Older machines use the “Before Serial No. 7751” sections. The serial number plate is on the right outside header. Write it down before ordering.

Are decals available individually or only as a set?

The manual states the decal set number is 900919 and includes 10 decals. Always order by set number. Individual decal part numbers are listed but the note says to order by set number.

How many pages is the catalog?

36 pages.
