Terex 3305B 1998 Parts Catalog

Let me tell you something right off: if you’re wrenching on a Terex 3305B and you don’t have the factory parts book open on the bench, you’re wasting your time and your customer’s money. I’ve seen guys try to order a steering cylinder seal kit off a third-party cross-reference and end up with the wrong bore size because some aftermarket database had a typo. That doesn’t happen with this Parts Catalog.

This is the original Terex publication from 1998 – PBS No. 348/3, Part Number 15268849. It covers the 3305B Off-Highway Truck powered by a Cummins NTA-855C, serial numbers T3481067 through T3481157. 420 pages, no reprints, no photocopies. This is the exact document the dealer parts counter used to pull numbers for your order.

Section Index – How the Book Is Laid Out

The binder is split into Major Sections, each covering a specific machine area. The Table of Contents lists standard sections and optional equipment sections separately, so you can jump straight to what you need. Sections include Chassis (Section 1), Front Axle (Section 9), Body System (Section 26), Steering components, Hydraulic system, and more. Each Parts Page carries an Index Code: three numbers – Major Section, Sub-section, and Page Code. That’s how you find the exact part in the exploded diagram.

For example, needing a steering cylinder seal kit? The Table of Contents points you to the steering sub-section, then the page code gets you to the exploded view with callouts. You don’t guess. You flip, match the index, and order the right part number. Period.

Warranty Coverage – Read This Before You Install

Terex’s factory warranty on replacement parts and attachments is spelled out inside (see page 3 of the OCR excerpt). Six months from sale, covering defects in material or workmanship. Does not cover negligence, overloading, or labor for removal/reinstallation. That information is worth noting when you’re dealing with a truck owner who thinks a seal failure is always a manufacturing defect. It isn’t – but having the factory language in front of you helps the conversation.

How to Navigate – Standard vs Optional TOC

The manual includes two separate Table of Contents pages: one for standard equipment (Sections 1, 2, 4, 7, 8, 9, 11, 12, 13, 15, 16, 17, 18, 26, 27, 59) and one for optional equipment (Sections 1, 2, 4, 8, 13, 15, 17, 18, 27, 59). This matters because the 3305B could be ordered with a body liner, different exhaust routing, or aftermarket A/C. The optional TOC lists only the sections that apply to those add-ons. If you’re rebuilding a truck that has been modified, check the optional index first.

Who Needs This Manual – Real-World Use Case

You’re a shop owner in San Antonio with a 3305B hauling limestone at a quarry. The front axle has a steering cylinder leak. You need the correct overhaul seal kit – not a generic one from the local hydraulic shop. You pull up this Parts Catalog, go to Section 9 (Front Axle), find the sub-section for steering, and read the index code. The exploded-view drawing lists every part with its OEM number. You order that part, not the “will fit” alternative. That saves you a second R&R and the customer’s downtime. DIYers on a farm with a single truck? Same rule applies. Don’t guess. Use the OEM catalog.

Source Authenticity – Why OEM Beats Aftermarket

I have a stack of aftermarket parts catalogs that use recycled diagrams from the 1980s with no revision dates. This Terex document is the real thing: published by Terex Equipment Limited’s Technical Publications Department in Motherwell, Scotland. The warranty page, the part numbers, the illustrations – they all came from the same engineering team that designed the truck. I have watched a tech order a brake caliper rebuild kit based on an aftermarket catalog and get the wrong piston diameter because the drawing was scaled wrong. That doesn’t happen with factory OEM paper. Automotive industry standards stress the importance of using original manufacturer documentation for critical safety components – and steering/hydraulics are definitely critical.

Frequently Asked Questions

Does this Parts Catalog include torque specs for fasteners?

No. This is a parts book, not a service manual. You get part numbers, exploded views, and ordering info. For torque values, you need the corresponding Terex 3305B service manual.

Is this the same as the dealer’s computer system?

Yes. Dealers used the same microfiche and later CD-ROM version. This PDF is a direct scan of the printed original. The index codes and part numbers match the Terex EPIC system exactly. If the dealer tells you a part is obsolete, you can challenge them with the number from this book.

My truck has a Cummins NTA-855C – is the engine section included?

The catalog covers chassis-mounted components and attachments. The engine itself (Cummins) is covered in a separate engine parts manual. This book includes engine-related items like the fan drive, radiator, charge-air cooler, and engine mount brackets – but not internal engine parts. You will want the Cummins manual for pistons, liners, etc.

Can I order a printed copy from you?

We sell digital documents only. You get the full 420-page PDF immediately. Print as many copies as you want for your shop table. We don’t offer hardback binders – but you can take the file to any print shop.

You have a Terex 3305B sitting in the yard with a blown hydraulic hose or a cracked steering box. You can either call the dealer and hope they read the right part number back, or you can hand them the OEM number from this book and confirm it yourself.
