Terex TR40, TR45 2010 Parts Catalog – Factory OEM Part Numbers & Diagrams

You’re looking at a Terex TR40, TR45 2010 Parts Catalog and need to track down a part. Maybe a steering cylinder in sub-section 0120, or a component in the body hoist system. Without the factory parts catalog, you’re guessing. Guessing costs time and money. I’ve been turning wrenches for 28 years, and I’ll tell you straight: if you don’t have the OEM book, you’re going to order the wrong part at least once. This 440-page document from Terex Equipment Limited gives you every part number, exploded view, and revision date – including the September 2010 update. For background on off-highway truck classifications, see Automotive Industry Overview.

What the Terex TR40, TR45 2010 Parts Catalog Covers

This book is divided into major sections that match the machine’s physical layout. You get SECTION 100 – CHASSIS, SECTION 140 – FRONT AXLE GROUP, SECTION 230 – BODY HOIST SYSTEM, and more. Each part is listed with its OEM number, quantity, and cross-reference to the diagram. The Terex TR40 and TR45 are off-highway trucks with Cummins QSK19-C525 Tier 3 engines and Allison M5610AR transmissions – the catalog covers both models from serial T8811011 upward. The Terex TR40 and TR45 share many components, but this catalog separates them where they differ, so you order the right part the first time.

SECTION 100 – Chassis and Frame Components

Frame rails, crossmembers, mounting brackets – all laid out in exploded views. If you’re replacing a cracked frame gusset or need the bolt kit for the suspension mounts, this section has the part numbers. I’ve seen guys try to match a bolt by eye and end up with a failure because they used the wrong grade. Factory specs don’t lie. Use them.

SECTION 140 – Front Axle Group: Steering Cylinder and Suspension

This section covers the front axle, kingpins, steering knuckles, and the steering cylinder sub-section 0120. The steering cylinder is a common wear item – seals blow, rods get scored. The catalog shows every seal, O-ring, and piston in the Cylinder assembly. Without the exact part number, you’ll waste hours trying to match a seal kit. I’ve seen it happen. Don’t be that guy.

SECTION 230 – Body Hoist System: Hydraulics and Cylinders

The hoist cylinders take a beating. This section gives you the complete breakdown of the body hoist system – pump, control valve, lines, and the lift cylinders. If you’re chasing a leak or need the mounting pin, you’ll find it here. The Terex TR40 and TR45 have different hoist configurations, so check the sub-section. The Terex TR40 operators manual also covers daily checks – grab that too: Terex TR40 Operators Manual – Factory Safety & Maintenance Guide.

Why a Factory Parts Catalog Beats Aftermarket Reprints

Aftermarket reprints often blur the drawings, mislabel part numbers, and skip updated revisions. This catalog is the original factory PDF published by Terex Equipment Limited, Motherwell, Scotland, dated September 2010. It includes the warranty page (page 3) and the index codes. A reprint might save you $10 but cost you a week of waiting for the wrong part. The Terex TR45 service manual has the torque specs and procedures you need for assembly – pair it with this parts catalog: Terex TR45 Service Manual – Factory OEM Specs for 488-Page Maintenance. And if you’re operating the truck, get the operator’s manual: Terex TR45, TR60 Operators Manual – Factory Specs & Safety.

The Terex TR40 and TR45 are part of the rigid dump truck family, as described in Automotive Industry Overview. This catalog is your parts bible – 440 pages of OEM diagrams and part numbers that let you order with certainty.

FAQ – Your Questions Answered

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Torque values are in the service manual.

Can I use this to rebuild the steering cylinder?

Yes. Sub-section 0120 gives exploded view and part numbers for every seal, O-ring, and piston. You’ll need the service manual for assembly procedures and torque specs.

Is this the same as a reprint from a third-party site?

Big difference. This is the original factory PDF published by Terex Equipment Limited, Motherwell, Scotland. Aftermarket reprints often blur drawings, mislabel part numbers, and skip updated revisions. This one includes the September 2010 revision. I’ve seen guys order a part from a reprint and it didn’t fit because the drawing was from an earlier serial number. Don’t trust reprints.

What serial numbers does this cover?

Serial Nos. T8811011 and above.
