GEHL CB800 Parts Catalog – What You Actually Get

If you’re chasing a part number on a GEHL CB800 forage harvester and the aftermarket list you found shows a different bolt than what came off, you know the drill. Another hour burned, another wrong order. The factory GEHL CB800 Parts Catalog fixes that. 64 pages of OEM exploded views, part callouts, and serial number splits that match what GEHL shipped. No reprints, no third-party redraws. That’s what I keep on the bench.

Decal Locations: Why They Matter

Pages 2-3 show the exact decal placements. That’s where you find the model and serial number – right below the Quick-switch Yoke on the main frame. The manual uses standard abbreviations for every fastener type: HHCS for hex head cap screw, HJN for hex jam nut, and so on. Memorize them or keep the list open; you’ll need it to decode the callouts.

Frame & Axle – Serial Number Split

GEHL changed the frame design at serial #3312. The manual splits every major section. Frame & Axle for units before #3312 covers pages 4-7; after #3311 goes to pages 8-9. Order the wrong bracket based on a generic list and you’re drilling new holes. This catalog gives you the exact part for your machine’s build date.

PTO & Drive – Two Versions, One Manual

Same split applies to PTO and drive. Before #3312: pages 10-13. After #3311: pages 14-17. The drive chain orientation is left-side when standing behind the harvester. The catalog calls out the sprockets, bearings, and chain lengths with part numbers. You can cross-reference with GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog if you have a skid steer that shares components.

Roller & Roller Drive – Common Failure Points

Roller sections span pages 18-23. If the roller drive is slipping, you need the exact roller and shaft assembly part. Again, serial split matters – before #3312 uses one set of rolls, after #3311 uses another. The manual lists Grade 5 cadmium-plated cap screws as standard; if the manual calls for a Grade B nut, don’t substitute. Torque chart is inside the back cover. I’ve seen guys snap bolts because they guessed 50 ft-lb when the spec called for 35. Page 55 also includes a separate torque wrench listing for the slow-down kit option.

Options & Accessories – What’s Covered

From page 44 through 56, you get all the dealer-installed options: electric transmission control, manual deflector, hydraulic cap control, control box wiring, and the slow-down kit. The length-of-cut gear set and cylinder knife set are also listed with part numbers. Liner kit, power extension cord – it’s all there. You want to add a 5-ft control stand extension? The parts are on pages 53-54. No need to call the dealer and wait for a fax.

Why an OEM Parts Catalog Beats Aftermarket Lists

Aftermarket parts catalogs often redraw diagrams and drop fastener callouts. This one is direct from GEHL. The note on page 2 says common hardware is listed but not illustrated – they expect you to use the attaching hardware table. Aftermarket printers skip that table. Also, GEHL won’t sell replacement tires directly; the manual gives wheel set numbers and tire size info so you can buy tires locally. You won’t get that from a third-party copy.

Torque Specs and Hardware Grades

Standard hardware torques are in a chart inside the back cover. All cap screws in this catalog are Grade 5 unless noted. Hex nuts for Grade 5 are Grade B; for other cap screws, Grade A. The manual uses abbreviations like SL for self-locking threads. If you’re rebuilding the bevel gearbox (page 32 for before #3312, page 33 after), you need that chart because a loose bolt will leak oil into the PTO.

FAQ – GEHL CB800 Parts Catalog

Does this parts catalog include torque specs?

Yes, standard hardware torque chart is inside back cover, and page 55 lists a torque wrench for options.

Can I use this for a CB800 with serial after 3311?

The catalog covers both serial ranges – each section has separate pages for before #3312 and after #3311. Look for the correct page range.

What is the difference between a parts catalog and a service manual?

A parts catalog gives you exploded views and part numbers for ordering. A service manual gives you procedures for disassembly, assembly, and diagnostics. If you need to know the tightening sequence for the bevel gearbox, you want the service manual. But if you need to identify which bearing, seal, or bolt goes where, the parts catalog is your reference. I keep both on the bench. This catalog has 64 pages of parts breakdowns, serial number splits, and hardware callouts. Don’t mix them up.

Are the illustrations OEM or aftermarket?

OEM from GEHL. The decal location diagram on pages 2-3 is factory, and all part numbers match the original prints.

This is the same document your dealer used before they switched to screen-based parts lookups. If you want to identify the right part, order it once, and get the machine back together without return trips to the supply house, Access the Factory Manual from AutoRepairManuals. That’s the only copy I’d put on a shop bench.
