Eaton 4000 1975 Parts Catalog – Factory OEM Breakdown for the Trojan Tractor Shovel

You have a Trojan 4000 on the lot and someone needs a steering cylinder. You look up a part number online from some parts aggregator, order it, and it shows up wrong because the serial number break changed in ’76. I’ve seen that eat a half-day of labor and a restocking fee. That’s why you want the Eaton 4000 1975 Parts Catalog from the factory – the same book that sat in the parts counter when this machine was new. 180 pages, printed October 1975, Manual No. T8069, Part No. 2022709. It’s the only one that uses the machine serial number to point you to the exact part.

Serial Number Identification: Why It Matters on the 4000

Page 2 of this manual starts with a blank form for machine serial number, engine model, transmission, front axle, rear axle. That’s not filler – that’s the key. Eaton built the 4000 with running changes. One clutch pack in a serial range 76-4011 and higher may be different from the one before it. Without the serial number, your distributor can’t cross-reference the part. This catalog lists every part with the serial range it fits. Skip that step and you’re ordering blind.

Parts Breakdown: What Sections Are Inside

The manual covers the entire Trojan Tractor Shovel – engine, transmission, front and rear axles, hydraulic system, operator compartment. Each major assembly has an exploded view with callouts and part numbers. The OCR excerpt confirms it includes both parts and operating instructions, so you get lube intervals and basic adjustment specs alongside the part numbers. For a shop that sees these machines regularly, that’s the difference between pulling a wrong seal and having the right one on hand.

Need to chase a hydraulic leak? The catalog breaks down the pump, control valve, and cylinder seals by serial number. You’ll find the O-ring size and the Eaton part number – not a generic cross-reference from a repackager. Automotive Industry Overview shows that even today, aftermarket catalogs mix up metric and SAE threads. This manual is all factory-original – no conversion errors.

Is This Manual a Service Repair Guide or Just a Parts List?

Straight answer: it’s a Parts Catalog with operating instructions. You won’t find step-by-step engine overhaul torque sequences. What you get is the parts breakdown, the part numbers, and the serial-number ranges those parts apply to. If you need a rebuild procedure, you’ll want the service manual for the 4000. But if you’re ordering parts – and doing it right – this catalog is the final word.

I’ve had guys argue that a third-party website’s part number is “the same.” Then they get a brake shoe that’s 1/8” too narrow. The factory catalog uses the same drawings the assembly line used. That’s why your parts manager keeps a copy locked in the file cabinet – because it works.

3 Reasons to Use the Factory OEM PDF Instead of a Copy

First, clarity. The original scans from 1975 are sharp – no blurry callouts. Second, the serial-number index is complete. Reprints often miss the revision 2 updates that changed a dozen part numbers. Third, you get the full 180 pages, including the operator instruction supplement that tells you how to lubricate the steering pivots. A photocopy from a dealer in the 80s will be missing half that.

This is the exact PDF from the Eaton archives – no watermarks, no pages removed. Eaton RTLO-16618A 2010 Parts Catalog – Factory Breakdown for Truck Shops is a different manual for a modern transmission, but the same factory-only principle applies.

What Torque Values and Fluid Capacities Are Listed?

The operating instruction section includes capacities for the hydraulic tank, differential, transmission. Page 73 (check the actual page for your access) gives the charge pressure for the hydraulic system. You also find lube intervals for every grease fitting – not generic “every 50 hours,” but specific to the 4000’s pivot pins and bucket linkage. If you’re restoring one of these machines, that information keeps you from over-greasing and blowing out seals.

FAQ – What You Need to Know Before Buying

Does this manual cover repair procedures, or is it strictly a parts list?

It’s primarily a parts catalog with operating instructions. You get exploded views of assemblies, part numbers with serial-number applicability, and lube/service data. For overhaul procedures you need the separate service manual.

How do I use the serial number to order parts correctly?

Locate the serial number plate in the operator’s compartment – page 3 of the manual explains where it is. Then find the section for the assembly you need. Each part number will list the serial range it fits (e.g., “Serial No. 76-4011 & Higher”). Order that exact part number.

Is this a printed book or a digital access?

You access a high-resolution PDF. No shipping, no wear. Print it yourself or keep it on your tablet.

Will this work for a 1974 Trojan 4000 or only 1975?

The manual is dated October 1975 and covers serial numbers 76-4011 and higher. If your machine is older, the part numbers may differ. Always cross-check your serial number against the ranges in the catalog.

Source Authenticity: Why Factory OEM Beats Aftermarket

I’ve compared aftermarket parts catalogs for Eaton equipment side by side with this factory PDF. The aftermarket ones are missing serial-number breaks – they treat all 4000s as identical. That’s wrong. The Eaton engineers changed the hydraulic filter head in 1976. Good luck getting that wrong without a return. This manual is the one the factory service techs used. No repackaged data, no guesswork. Eaton RT-8908LL 2006 Parts Catalog – Factory PDF Manual is another example of the same standard – factory part numbers you can trust.

If you work on heavy construction equipment from the 70s, you know that aftermarket sources mix up part numbers for the Internal Combustion Engine components – fuel injectors, pumps, gaskets. This catalog keeps you straight.
