Terex TA40 2002 Parts Catalog – OEM Factory Manual

If you’ve ever ordered the wrong seal kit for a TA40 hoist cylinder because some aftermarket cross-reference lied to you, you know the drill. That wasted billable hour, the second trip to the dealer, the truck sitting dead on the pad. This Terex TA40 2002 Parts Catalog is what you use to make sure that doesn’t happen. It’s not a service manual – it’s the parts book. 304 pages of exploded views, full part numbers, and serial number breaks. The index code system on page 5 tells you exactly where to look. No guessing which revision fits your machine. From serial number A8201001 and up, with the Jan 02 revision. That’s the kind of specificity you need when your customer’s haul road is waiting.

Section 100 – Chassis: Frame, Fenders, and Mounts

The first major section in this parts book covers the chassis group. You’ll find part numbers for frame rails, crossmembers, fender assemblies, and all the brackets for engine mounts. The illustrations are line drawings with callouts keyed to the parts list. If you need a front frame weldment or a rear hitch pin, this is where you start. The index code on the top left of each page tells you you’re in Section 100. Don’t waste time flipping randomly – the table of contents lists every subsection.

Section 140 – Front Axle Group: Steering Knuckles and Hub Parts

Front axle components on the TA40 are heavy. Steering knuckles, kingpins, hub assemblies, brake hardware – all covered in Section 140. The parts list includes the exact Terex part numbers, quantities per assembly, and any supersessions. If you’re rebuilding a front axle, you need this section to order the correct bearing cones and seal kits. Aftermarket vendors love to tell you a generic seal will work. The manual says otherwise, and page 5’s index code system prevents mix-ups between the front axle group and, say, the body hoist system.

Section 230 – Body Hoist System: Cylinders, Valves, and Tubes

Hoist cylinders on these trucks take a beating. Section 230 gives you the complete breakdown of the body hoist system – the lift cylinders, control valves, hoses, and tube assemblies. Each component has a part number. If you need the seal kit for the hoist cylinder, the manual lists it by itself. No generic “fits all” nonsense. This is the same parts book Terex dealers used in 2002. You can cross-reference the numbers against stock you already have. The illustration for the hoist control valve shows every spring and spool. That level of detail saves you from ordering a whole valve when all you needed was a $12 O-ring.

How the Index Code System Works

Page 5 of this manual explains the index code printed at the top left of each parts page. It’s three numbers – the first is the Major Section (e.g., 100 for chassis), the second is the Sub-section, the third is the model PLI number. For example, if you see “140-02-01”, that’s front axle group, sub-section 02, PLI 01. The Table of Contents (pages at the front) lists every section and sub-section. So to find steering cylinder parts, you’d look in the Table of Contents for the steering group, then go to that section index. This system keeps all 304 pages organized. You don’t need to thumb through every page – just follow the index.

Why OEM Parts Catalog Beats Aftermarket

Aftermarket parts catalogs often list “equivalent” part numbers that might or might not fit. This Terex book gives you the exact Terex part number, the supersession history, and the correct revision. The warranty on page 3 applies only to parts sold by authorized Terex dealers. If you use a non-OEM part and it fails, you get no coverage. The catalog also includes notes like “from serial no. A8201001” – serial number breaks that aftermarket sources ignore. You want to bolt on a final drive gear? You need the right gear ratio, which the parts book specifies. I’ve seen guys order the wrong gear because a third-party site said “fits TA40”. This manual would have caught that.

Audience Fit: Who Needs This 304-Page Document

This is for the mechanic or equipment owner who maintains a Terex TA40 articulated truck. Not for the guy who changes oil once a year. If you’re rebuilding a differential, replacing a body hoist cylinder, or wiring in a new harness, the parts catalog is your first stop before ordering anything. It’s also useful for shops that buy used trucks: you get the serial number, check the manual, and know exactly what parts were installed at the factory. The manual is 304 pages, published in 2002 (revised Jan 02). The Detroit Diesel Series 60 engine is covered as part of the truck – engine-specific part numbers are in the appropriate sections. Pair it with a service manual for full repair procedures.

Frequently Asked Questions

Does this parts catalog include aftermarket part numbers?

No. Only Terex OEM part numbers are listed.

How do I find the correct part for my machine’s serial number?

The manual is organized by Major Sections with index codes explained on page 5. First, confirm your machine’s serial number (the manual covers from A8201001). Then use the Table of Contents to locate the relevant component group – for example, steering cylinder parts are in the steering section. Each part listing includes the serial number applicability. If your serial number falls within the range, the part number is correct. The warranty on page 3 applies only to Terex parts installed by an authorized dealer. Always cross-reference the revision date (Jan 02) to ensure you have the latest part supersessions. This manual is the 2002 revision; later revisions may have changed parts, so check the production date of your truck.

When you buy this manual, you get the genuine OEM file. No scanned copies, no missing pages.
