O&K 2000 1985 Parts Catalog – What You Actually Need on the Bench

If you’re ordering parts for an O&K 2000 wheel loader and guessing the part number, you’re wasting time and money. This factory Parts Catalog fixes that. Published in 1985 by Trojan Industries Inc. – manual TB104, part number 2023080 – it covers serial numbers 20‑1998 and up. 231 pages of exploded diagrams, OEM part numbers, and notes on when a part is not serviced separately. I’ve seen too many guys order the wrong hydraulic cylinder because they didn’t check the serial range. This manual forces you to do it right.

Accelerator Pedal & Linkage – Two Versions, One Manual

The Table of Contents shows two separate entries: GM version on pages 36‑37 and CD version on pages 38‑39. Why? Because machines left the factory with different engines and throttle setups. If you grab a generic aftermarket diagram, you’ll get the wrong cable bracket. This catalog lists both, and you need your machine’s serial number to pick the right one. No shortcuts.

Air System Piping – GM vs CD Reservoir Layout

Air reservoir piping is split again: GM on pages 134‑136, CD on pages 138‑139. The air dryer installation gets its own section (pages 139A‑1390). These aren’t generic schematics – they’re drawn from the actual production line. If you’re swapping an air governor (page 134‑139), the part number here matches what Trojan shipped. Aftermarket catalogs usually merge everything into one drawing and miss the bracket differences.

Axle Assembly and Cradle – Page References You Can Trust

The front and rear axle assemblies share pages 154‑155 and 168A. Axle cradle is on pages 22‑23. The brake group axle covers pages 158‑161. Every part number is tied to an illustration. Page 3 of the manual states: “Determine the basic system or assembly in which the part is used, and find this system or assembly in the Index.” That’s how you avoid ordering a seal kit that doesn’t fit your axle serial number.

Bucket Assembly and Cylinders – Know the Difference Between Lift and Bucket Cylinders

Bucket cylinder assembly is on pages 80‑81. Lift cylinder assembly follows on pages 82‑83. The bucket itself and attachments are on pages 21‑210. If you need the automatic bucket leveler (pages 174‑175) or the bucket leveler indicator, those are separate listings. Standard aftermarket manual would lump them into one bucket section. This catalog keeps them separate because the part numbers are different. Check your serial number.

Parts Ordering – Why Your Serial Number Matters

Page 2 of the manual includes a blank form for machine serial number, engine model, transmission part number, front and rear axle part numbers. The introduction repeats: “the SERIAL NUMBER of your machine must accompany every repair parts order.” If you order without it, you’ll get the wrong brake group or control valve. The manual also explains abbreviations: A.R. (As Required), N.S.S. (Not Serviced Separately), N.I. (Not Illustrated). That last one saves you from calling the supplier asking why a part isn’t shown – it’s used but not drawn.

Source Authenticity – Factory Trojan Industries Documentation

This is a direct scan of the original Trojan Industries Inc. manual. Not a third-party compilation. The OCR excerpt shows the exact language from page 1: “O&K 2000 Parts Manual TB104 Serial No. 20‑1998 and up.” The table of contents matches the actual printed book. If you’ve ever used an aftermarket parts list that mixes up CD and GM air piping, you know why this matters. Click O&K 2000 Parts Catalog to see the full TOC.

3 Reasons to Trust This Manual Over Aftermarket Copies

1. Serial-number-specific part breakdowns – The manual was updated with Revision 2 in September 1985. Aftermarket CDs just reprint one base version.
2. N.S.S. and N.I. flags – You know when a part isn’t serviceable alone, saving you from buying a seal that can’t be replaced without the whole housing.
3. Explicit page numbers for each system – Torque values? Not in a parts catalog, but the illustrations are indexed so you can cross-reference with the service manual. For the broader context, see Automotive Industry Overview and Automotive Industry Overview.

Frequently Asked Questions

Does this manual cover the engine internal parts?

No. This is strictly a parts catalog – it shows assemblies and part numbers, no rebuild specs. You need the service manual for torques and clearances.

What do the abbreviations A.R., N.S.S., and N.I. mean?

A.R. = As Required – quantity varies per machine. N.S.S. = Not Serviced Separately – you buy the whole assembly. N.I. = Not Illustrated – the part exists but isn’t shown in the diagram. Page 3 explains all three.

Will this manual work for a 1990 O&K 2000?

Only if your serial number falls within 20‑1998 and up. Trojan updated the manual with Revision 2 – later serial numbers may have different parts. Check the serial plate on your loader.

Is this a factory-licensed reprint or a copy?

This is a direct scan of the original Trojan Industries Inc. manual, part number 2023080. It includes the original introduction, index, and all 231 pages. No missing pages, no third-party editing.
