O&K 2000 Parts Catalog – Factory OEM Parts Identification for Trojan Loaders

If you’re ordering parts for a Trojan Model 2000 loader without the factory O&K 2000 Parts Catalog, you’re burning hours on returns and wrong-fit pieces. Aftermarket part lists love to reuse numbers that kind of look right, but then you get a brake valve that doesn’t match your machine’s serial number cut-off. I’ve seen guys order three bucket cylinders before figuring out they needed the version for the 3-spool hydraulic system. That’s time you don’t get back.

This Parts Catalog runs 245 pages of OEM exploded views, part numbers, and reference notes. It’s printed by Trojan Industries (the original manufacturer), not some third-party recompilation. Every page matches what the line workers used when your machine was built. If you care about getting the right part the first time, you start here.

Accelerator Pedal and Linkage: Page 40–43

Two separate accelerator setups live in this machine – General Motors (GM) and a CD variant. Page 40 shows the GM linkage, page 42 covers the CD version. The parts list includes the exact pivot pin, return spring, and bracket hardware. If your pedal feels sloppy or the linkage binds, you can locate the worn bushing by matching the diagram to your machine’s layout. No more buying the whole assembly when you just need a retaining ring.

What Parts Are Covered in This 245-Page Catalog?

The table of contents reads like a full machine breakdown. Here’s a sample of what you’ll find indexed by page number:

• Air Cleaner (GM) – 58, 59
• Air Cleaner (CD) – 60, 61
• Air Compressor – 146–148
• Axle Assembly – 160, 161
• Bucket Cylinder Hydraulic System – 82, 83
• Brake Valve – 152, 153
• Transmission Control Valve – 8–10
• Cab, Enclosed – 178–183

That’s not a full list – just a taste. The catalog sections are grouped by system: engine, powertrain, hydraulics, brakes, cab, electrical. Every part number ties back to a specific illustration.

Why Aftermarket Part Lists Fail (and OEM Doesn’t)

I’ve had jobs where a customer brought in an aftermarket parts book for a 2000 loader and the part number for the automatic hoist cut-out valve was wrong. The aftermarket list omitted the revision note that said “includes Revision 4.” That revision changed the detent wiring on the bucket leveler. Without that note, you order the old valve assembly, it doesn’t mate with the wiring harness, and now you’ve got a machine that won’t lift. This catalog is Revision 4, Manual Part No. 2022992. That’s the real deal. For more on why OEM documentation is the standard in the Automotive Industry Overview, the principle applies to construction equipment too.

Axle Assembly and Cradle: Matching Part Numbers to Serial Numbers

Page 160 covers the axle assembly. The parts list includes the axle cradle (page 16–17) and all bearing cups, seals, and spacer shims. The catalog explicitly states: “Machine Serial Number must accompany every repair parts order.” I’ve seen guys skip that step, then the front axle they ordered doesn’t fit because their machine was built after a running change. This manual gives you the exact part number for your serial number range. Page 160 shows the axle assembly illustration – you’ll see the breakdown of the differential housing, wheel hubs, and brake head components.

Using the Index to Find What You Need

Start with the index at the front of the catalog. Find the system – say ‘Controls, Main Hydraulic Valve (2 Spool)’ – and the page number is right there. Flip to that page, match the exploded view to your machine, and read the part number from the list. The catalog uses abbreviations like N.S.S. (Not Serviced Separately) so you don’t waste time trying to order a seal that only comes with the whole valve spool. If a part is marked N.I. (Not Illustrated), the description tells you it’s used but not drawn – usually something like a hidden O-ring.

FAQ

Can I use this parts catalog for a different O&K model?

No. This is specific to the Model 2000 loader only. Different models have different part numbers and revisions.

Do I need the machine serial number to order parts?

Absolutely. Trojan Industries made running changes during production. Without the serial number, you risk ordering a part that doesn’t fit. The catalog’s introduction states: “Because we are constantly upgrading our equipment, it is necessary that the SERIAL NUMBER of your machine accompany every repair parts order.” If you order an air compressor assembly for a machine built after a certain revision, the piping and reservoir setup changed – page 138-141C vs 142-143. Skip the serial number and you’ll get the wrong bracket kit. This is not a suggestion; it’s how the system works. Write down your machine’s serial number before you call or order online.

That’s the nuts and bolts of it. You want to keep your Trojan 2000 loader running without wasting money on wrong parts? Get the factory documentation that the line built it with. Access the Factory Manual now and stop guessing.
