GEHL CB860 Parts Catalog – What You Get When You Order by the Book

I’ve been turning wrenches for 28 years, and I’ll tell you straight: ordering parts without the factory Parts Catalog is like trying to torque a head bolt with a pipe wrench. You might get close, but you’ll be making a phone call later. This GEHL CB860 Parts Catalog – 66 pages of factory-issued part numbers, exploded views, and torque specs – is what you need if you want the right part the first time. Skip the aftermarket reprints that blur the callouts. This is the original GEHL COMPANY document, Form No. 904076.

Before you start pulling the implement drive line or ordering a new main frame, read the Introduction on page 2. It tells you exactly how to read the part numbers: indented hardware below the parent part, abbreviations table, and the standard attaching hardware torque values on the inside back cover. If you ignore that, you’ll order a cap screw that’s Grade 5 when you need Grade 8, or you’ll miss the fact that replacement tires must be bought locally – GEHL will not sell you a tire. They’ll sell you a wheel set, and the tire size is called out with the set. That’s page 2 stuff. Read it.

Decal Locations – Why You Need to Read Them

Pages 2-4 cover decal locations. This isn’t just for show. Decals tell you safety warnings, hydraulic fluid specs, and lube intervals. If you’re rebuilding a CB860 that’s had decals peeled off, this manual shows you where each one goes. You can order the correct decal by part number from the list. I’ve seen guys skip this and then wonder why the new operator can’t find the PTO engagement label. Don’t be that guy.

Main Frame, Drawbar & Attachment Lift – Identify Correctly

Pages 6-7 cover the main frame, drawbar, and attachment lift. The parts list is broken down by assembly. You’ll see the cutting cylinder shaft bearing location referenced – the serial number plate is on the right side of the main frame adjacent to that bearing. Right and left are determined from behind the unit facing forward. So when you’re ordering a drawbar pin, you know it’s left-hand side. If you’re working on a unit that’s been modified, the manual’s note says GEHL reserves the right to make changes without obligation to retrofit. That means you need to verify your serial number against the parts list. The manual tells you how.

Torque Specs on the Inside Back Cover

Do not skip the inside back cover. Standard attaching hardware torque values are printed there. Cap screws are Grade 5 unless otherwise specified. Hex nuts are Grade B for Grade 5 screws. This is not a suggestion – it’s the factory spec. I’ve pulled apart enough jobs where someone used a generic torque chart and stripped a thread. Use the manual’s values. They’re on the inside back cover, not buried in the middle. Go find them.

Implement Drive Line – Finding the Right Pulley

The implement drive line section is critical. The manual lists pulleys, belts, and bearings with specific part numbers. If you’re replacing a worn pulley, don’t just measure the diameter – the manual gives you the exact part number and any special notes about keyway size or set screw location. The abbreviations table (page 2) decodes things like “SHC” for Socket Head Cap screw and “FLN” for Flanged Lock Nut. Use it. Ordering the wrong pulley because you misread “SHC” as “SHCS” means a week of downtime waiting for the right one. I’ve seen it.

66 Pages – Not a Repair Manual, But the Parts Bible

This is a Parts Catalog, not a repair manual. It won’t tell you how to rebuild the cutting cylinder. It will tell you the exact part number for the cylinder shaft bearing, the seal, and the retaining ring. If you’re pairing it with a service manual, you’re golden. For example, the GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog”>GEHL SL4640, SL4840, SL5640, SL6640 2005 Parts Catalog covers skid loaders – different machine, but same factory documentation philosophy. If you need the larger forage harvester family, check the GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs”>GEHL SL7610, SL7710, SL7810 2005 Parts Catalog – OEM Factory Specs or the GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual”>GEHL RS6-34 2013 Parts Catalog – Factory OEM Manual. All OEM, all factory.

Can I use this Parts Catalog to do a full engine rebuild?

No. This is a parts identification manual, not a service procedure manual. It gives you the part numbers for gaskets, pistons, rings, and bearings, but it won’t walk you through assembly order or torque sequence for the head bolts. You need the service manual for that. But if you’re ordering parts, this is the only source you should trust.

What torque values are actually in the manual?

Standard attaching hardware torque values are printed on the inside back cover. The manual states that unless otherwise specified, all cap screws are Grade 5, and hex nuts for Grade 5 screws are Grade B. The torque table covers common sizes from 1/4-inch to 1-inch cap screws. If your application requires a special torque – like for the cylinder shaft bearing retaining bolts – the specific value will be called out in the parts list or in a note next to the part. Check the parts list for any footnotes. The manual explicitly says “Standard attaching hardware torque values are also provided on the inside back cover.” So that’s your starting point.

If you’re tired of guessing which bolt goes where and just want the factory numbers in front of you, this is the document. Access the Factory Manual now and get the CB860 parts catalog on your bench – no more holding the wrong part up to the light.
