GEHL CB600 Parts Catalog – Factory OEM Parts Breakdown

If you are tearing into a GEHL CB600 forage harvester without the factory Parts Catalog, you are guessing part numbers against a worn-out decal. Guessing on which cylinder assembly fits your serial number range, or which transmission gear set belongs to a 540 RPM or 1000 RPM PTO. That kind of guessing gets you a box of wrong parts and a machine that sits. This is the real OEM document – GEHL CB600 Parts Catalog, 68 pages, straight from the manufacturer.

Cylinder and Transmission Sections – Serial Number Splits Matter

The Cylinder section runs pages 16–17. You get the whole cutterhead assembly: knives, shear bar, bearing mounts. But here is where most people mess up – the manual breaks parts by serial number ranges. Frame and axle have three different setups: before #8601, between #8600 and #15801, after #15800. The same goes for Roller & Roller Drive and Length-of-Cut sections. Use the wrong serial number range and the part number won’t match your machine. The Transmission section covers pages 21–24, with separate subsections for 540 RPM and 1000 RPM tractor PTO setups. That distinction will save you a day of disassembly.

Why Skip Aftermarket Copies and Stick with This OEM Print

Aftermarket parts catalogs often omit the serial number splits and the attaching hardware table. They might list a generic bolt where the factory calls for a Grade 5 cap screw with a specific torque value. This manual includes a torque specifications chart on the inside back cover and an attaching hardware table that tells you exactly which nut and washer grade goes where. I have watched a technician snap a Grade 2 bolt in a driveline because he used a generic number – that does not happen when you use factory data.

Torque Wrench Required – Specs Are in the Back

Standard hardware torques appear in a chart at the end. The manual explicitly states all cap screws or bolts are Grade 5, cadmium or zinc plated, and hexagon nuts for those are Grade B. Other fasteners get Grade A. Do not walk up to this machine with a calibrated wrist. Use the chart. The attaching hardware table inside the back cover also gives part numbers for common hardware – but note that common hardware is listed for mounting only; if you need a replacement, order from that table separately.

3 Things to Check Before Ordering Parts

1. Serial number – locate the decal on the main frame below the right Quickswitch Yoke. Write it down before you open the manual.
2. Part number from the exploded view – match the callout number to the parts list. Do not assume the old part number is still current; the manual covers changes.
3. Hardware grade and quantity – note whether the fastener is a HHCS, HN, LW, etc. The abbreviation list on page 2 decodes every one.

Decal Locations and Abbreviations – Simple but Overlooked

This manual puts decal locations inside the front cover. That is where you find the model/serial number decal, safety decals, and drive-chain decals. Also included is a full abbreviation table: CB for carriage bolt, HHCS for hexagon head cap screw, PTHMS for Phillips truss head machine screw, and so on. You need to know these because the parts list uses them constantly. Right and left are defined from behind the machine facing forward – drive chains are on the left side. That prevents mix-ups when ordering sprockets.
