GEHL CB1250 Parts Catalog

If you are chasing a part number for a CB1250 forage harvester and the aftermarket catalogs keep giving you the wrong bolt, the wrong seal, or the wrong entire assembly, you already know the cost of that guess—lost time, returned parts, and a machine that sits. This 52-page factory parts catalog from GEHL eliminates the gamble. Every exploded diagram, every fastener callout, every assembly grouping came off the same drawing board as the machine itself.

Why a Factory Parts Catalog Beats Aftermarket

Aftermarket parts catalogs often re-draw diagrams from memory or copy outdated scans. The GEHL CB1250 Parts Catalog is an original OEM document. That means the hydraulic hose routing on page 30 matches exactly what the assembly line installed. The decal locations on pages 2-3 show where every safety label and warning decal goes. When you order a replacement blower housing from the Blower section (pages 14-15), you get the correct GEHL part number, not an approximation.

Standard hardware torques are listed in a chart at the back of this manual, using Grade 5 cap screws and the correct hexagon nuts (Grade B for Grade 5 fasteners). The abbreviations table—HHCS, HN, LW, PW—tells you exactly what each fastener code means. No translation needed.

Guards, Covers, Shields & Troughs – Pages 10-11

These pages cover the sheet metal that keeps the operator safe and the crop flowing. The parts list identifies each shield, trough, and cover with its factory part number. If you need a replacement deflector cap, flip to page 12 under the Cutting Mechanism section. The drawing shows how the cap mounts, and the hardware table tells you the grade of cap screw required.

Hydraulics Section – Page 30

One page for the entire hydraulic system. That might sound thin, but GEHL packed every cylinder, hose, fitting, and valve into a single exploded view. The parts list includes the O-ring sizes and the correct tube fitting part numbers. If you are rebuilding a cylinder, the seal kit number is called out. No aftermarket manual gives you that level of detail without cross-referencing three different sources.

Length-of-Cut Transmission – Pages 26-27

This transmission controls how fine the forage is chopped. The two-page spread breaks down the gear case, shafts, bearings, and the shift mechanism. The exploded view shows the order of assembly—critical when you are replacing bearings or a gear. The parts list includes the correct key stock and snap ring dimensions. Torque specs for the housing bolts appear in the main hardware torque chart at the end of the manual, not buried in a footnote.

3 Reasons to Use the Abbreviations Table

First, the manual lists common hardware like cap screws and nuts in the parts list without illustrating them. That saves space, but you need to know what “HHCS” means—Hexagon Head Cap Screw. Second, the attaching hardware table inside the back cover gives you the part numbers for those common fasteners if you need to order them separately. Third, the table tells you the plating (cadmium or zinc) and the grade. Do not assume a generic bolt from the bin matches the factory spec.

Cutting Mechanism: Blower, Spinner, and Feed Rolls

The Cutting Mechanism section spans pages 8-21. It covers the Deflector & Cap (page 12), Blower Drive (page 13), Blower Housing & Fan (pages 14-15), Spinner & Drive (pages 16-17), and Feed Rolls (pages 18-21). If the blower fan is throwing chips or the feed rolls are slipping, the exploded diagrams show the bearing locations and the roll drive chains. The Roll Drives section on pages 18-19 includes the stationary and supporting parts. Having the exact OEM part numbers means you order a roll shaft that matches the spline count and the bearing bore.

FAQ

Is this the same as a service manual?

No. This is a parts catalog. It gives you exploded diagrams, part numbers, and hardware callouts. It does not contain step-by-step repair instructions or troubleshooting procedures. For that you need the separate service manual.

Does it include torque specs?

Yes, a standard hardware torque chart is printed at the end of the manual. It covers Grade 5 cap screws and the corresponding nut grades. Specific component torques (like bevel gearbox bolts) are not listed separately; you use the standard chart.

Can I use this catalog for a gasoline-powered CB1250?

The CB1250 forage harvester was designed for diesel power. For engine part numbers, consult the engine manufacturer’s parts catalog. This manual covers the harvester chassis, driveline, cutting mechanism, hydraulics, and options. If you need to understand diesel engine fundamentals, read this Wikipedia article on diesel engines for background, but use the engine manual for parts.

How are parts referenced in the catalog?

Each part has a GEHL part number, a description, and a quantity per assembly. The illustrations use reference numbers that connect to the list. Common hardware (nuts, bolts, washers) is listed but not drawn on the diagram. For those fasteners, refer to the attaching hardware table inside the back cover.
