Trojan 2000 Parts Catalog – Factory Parts Breakdown for Tractor Shovel Models

I’ve spent enough time staring at scrapped-out loader parts stacked on a bench to tell you this straight: if you don’t have the right part number in your hand before you call the dealer, you’re wasting time. This Trojan 2000 Parts Catalog is the 212-page factory document that Eaton Corporation originally issued to dealers and shops back in 1975 for the Model 2000 Yale Loader (serial no. 20-1011 & higher). It’s not a reprint or a scan of a scan. It’s the original OEM parts book, manual number TB076, part number 2022950. Pull a part out of a bin, lay it next to the exploded diagram on page whatever page it is, and you’ll know you grabbed the right one before you walk back to the machine.

This catalog covers the full Trojan 2000 tractor shovel – engine, transmission, both axles, hydraulics, steering, frame, and cab. Every section lists the part number, description, and quantity used. If you’ve ever ordered a hydraulic pump seal that didn’t fit because some aftermarket catalog used a generic cross-reference, you’ll appreciate why I won’t touch third-party parts lists. This one came from the original manufacturer.

Why a Factory Parts Catalog Beats Aftermarket Lists

Aftermarket parts catalogs guess. They’ll list a “equivalent” part that may or may not match your serial number range. This Trojan 2000 manual is keyed to serial number 20-1011 and higher. That means every part listed corresponds exactly to the design changes made after that serial break. If your machine is serial 20-1010, you’ll need the earlier catalog – that’s how precise factory docs are. The manual also includes the official Eaton warranty terms on page 3, so you can read exactly what’s covered and what isn’t. No interpreting vague clauses. It states the 180-day or 1,000-hour limit right there in black and white.

Machine Serial Number and Component Tracking

Inside the front cover of the manual there’s a registration page where you fill in your machine serial number, engine model and serial, transmission part and serial, and both axle part and serial numbers. That page exists because Eaton expected shop foremen to keep this manual with a specific machine for its entire life. You do the same: write your numbers in, then when you need a ring gear or a brake piston, you go straight to the section that covers your exact axle. No flipping through generic sections. The manual’s organization follows the machine’s driveline layout – engine, torque converter, transmission, front axle, rear axle, then the chassis and attachments.

For example, when you look up the front axle, you’ll find the carrier, differential, planetary hubs, and service brake components separated by sub‑assemblies. Each sub‑assembly has its own exploded illustration with callouts that point to the part number in the adjacent list. That’s how a real parts catalog works – you don’t need to be a parts specialist to understand it.

7 Systems Covered in This 212-Page Catalog

Open the manual and you’ll find sections for:

• Engine – air cleaner, manifold, mounts, and all gasket kits
• Torque converter and transmission assembly
• Front and rear drive axles (including planetaries)
• Hydraulic system – pump, control valve, lift cylinders, steering cylinders, and hoses
• Frame and fenders – radiator guards, fuel tank, grille
• Brake system – service and parking brakes, air control if equipped
• Cab and controls – steering wheel, pedals, instrument panel, seat

Each section lists the part numbers for components you’d realistically replace – seals, bearings, gaskets, filters, hoses, and castings. The catalog doesn’t include torque specs service procedures, but that’s not its job. Its job is to tell you the correct part number so you don’t order the wrong undercarriage bolt and hold up the job when the machine is down.

Who Needs This Manual – Real-World Use Case

If you own a Trojan 2000 loader – whether it’s sitting in your yard as a backup unit or running daily in a quarry – this catalog belongs in the toolbox or in a plastic sleeve in the cab. I’ve seen guys try to rebuild hydraulic cylinders by measuring the old seal and guessing the metric equivalent. Then the gland nut doesn’t thread back on because the backup ring was the wrong cross-section. With this catalog, you call the dealer or an OEM parts distributor and give them part number 478951 (fake example, but you get the point) straight from the page. No measuring, no guessing, no returns.

Shops that work on multiple construction equipment brands will also keep this as a reference for cross‑checking part numbers from other OEM suppliers. It’s also valuable for restoring an older Trojan – you can identify what parts are still available and what might have been superseded by a newer design.

Source Authenticity – Why It Matters

This manual is a direct factory file from Eaton Corporation, Construction Equipment Division, Batavia, New York – telephone area code 716 back when that meant something. The scanned file you access from AutoRepairManuals is the same document that sat in dealership parts departments. You get the original copyright notice, warranty boilerplate, and part number sequences. There’s no repagination, no crop marks from a copier, no hand-written notes from someone who didn’t know what they were doing. It’s the genuine article. If you’ve ever been burned by a third-party manual that listed a part number that turned out to be for a different production year, you’ll understand why I say stay with factory files.

FAQ – Trojan 2000 Parts Catalog

Does this catalog cover the engine overhaul procedures?

No. This is a parts manual, not a service manual. It identifies parts with numbers and exploded views. You’ll need the separate service manual for assembly and torque specs.

Will this work for a serial number below 20-1011?

Possibly some parts overlap, but the manual is specifically written for serial 20-1011 and higher. Earlier machines had different transmission and axle configurations. You’d be better off tracking down the earlier catalog for serial numbers below that break. Using this one for an older machine risks ordering the wrong part because Eaton changed designs at that serial break.

Are the part numbers still current with modern suppliers?

Some part numbers may have been superseded over the years. The catalog gives you the original Eaton part number. You then check with a current dealer or online parts cross-reference to see if it has been updated. At least you start from a factory number, not a generic description.

I need the wiring diagram for the lights – does this manual have it?

No wiring diagrams in a parts catalog. Electrical components like the light fixture, switch, and harness are listed as individual parts, but you won’t find a schematic showing wire colors and connector pinouts. That’s in the service manual.

If you’re tired of chasing wrong parts or paying restocking fees on returns, this catalog gets you the right part number on the first call. Access the Factory Manual now and keep it with your machine for quick reference.
