Terex 3311E Parts Catalog

I’ve seen guys order three different steering cylinders before they found the one that fit. Then they blamed the supplier. That’s not supplier error — that’s ordering without a proper Terex 3311E Parts Catalog. When you’re working on a Cummins KTA-38C powered off-highway truck with serial numbers T3851106 through T3851138, guesswork costs you time and money. This is the factory parts book, 466 pages, published by Terex Equipment Limited in Motherwell, Scotland, dated August 1997. It’s the same binder the dealer parts counter uses.

Parts Book Structure: What the 466 Pages Contain

The book is split into major sections — Chassis, Front Axle, Body System, and more. Each section has a three-number index code printed on the right-hand edge of every parts page. The first number is the major section, second is the sub-section, third is the page within that sub-section. If you need a brake pedal assembly, you don’t flip randomly. You go to the Table of Contents, find Section 17 or whatever it is, and drill down. The OCR excerpt shows the same layout: Section 1 – Chassis, Section 9 – Front Axle, Section 26 – Body System. That structure is repeated across the standard and optional tables of contents. It’s not complicated, but you have to read the index first.

Index System: Navigating the 466 Pages

Page 1 of the catalog gives you the part number (15268663), the PBS number (385/2), and the exact serial number range. That’s your first check — if your truck isn’t in that serial range, this book doesn’t cover it. The index pages group sections together: Sections 1, 2 & 4 on one page, then 4, 7, 8 & 9, and so on. There’s also an optional table of contents that jumps sections differently. I always use the standard one because it follows the machine layout. Don’t start ordering parts until you’ve verified your section and sub-section against the page code.

3 Critical Sections for Driveability Repairs

If you’re chasing a drivetrain issue, three sections will get you the parts you need. Section 1 – Chassis includes frame and mounting hardware. Section 9 – Front Axle covers steering knuckles, kingpins, wheel bearings. Section 26 – Body System handles the dump body hydraulics and pivot pins. Each section has its own sub-section breakdown — for example, steering cylinder components are listed under a sub-section within Section 9. The table of contents points you to the exact page code number. No flipping through 400 pages blind.

Why OEM Part Numbers Matter

Aftermarket catalogs renumber parts, put them in different groupings, and often leave out supersession history. This Terex book gives you the factory number — the one stamped on the casting or printed on the original bag. When you call a dealer, they ask for that number. If you show up with a generic cross-reference, you’ll get the wrong part. Page 3 of this catalog includes the warranty statement: Terex warrants new replacement parts for six months. That warranty only applies if you’re using genuine parts. The book also states that defective parts must be returned to an authorized dealer with the purchase slip. Don’t lose that page.

Check the Warranty Before You Order

Page 3 covers the warranty in plain language. Six months from date of sale, Terex will repair or replace defective parts. It does not cover labor for removal or reinstallation, nor consequential damages. If you install a part wrong because you didn’t have the right procedure, that’s on you. The parts catalog doesn’t give you torque specs or installation steps — that’s what the service manual is for. But having the correct part number means you don’t waste money on something that doesn’t fit. Want to see the full list of related manuals?

What serial numbers does this catalog cover?

T3851106 through T3851138. Check your truck’s serial plate before buying.

How do I find the right part number in 466 pages?

Use the Table of Contents. Find the major section, then the sub-section index code. Each parts page shows the three-number code on the right edge.

Can I use aftermarket parts instead of OEM numbers from this book?

You can, but you’ll lose the six-month Terex warranty and risk fitment issues. Aftermarket cross-references often skip supersession and revision history. This catalog lists the exact factory part number that matches the original engineering release. When a part has been updated, the book reflects it. If you substitute without checking, you may end up with a component that doesn’t interface correctly with mating parts — especially on hydraulic systems where port sizes and thread pitches change. I’ve seen aftermarket cylinders that bolted up but leaked because the O-ring groove was cut to a different spec. Spend the ten minutes to verify the OEM number; it’s cheaper than redoing the job.

Is this the same as a service manual?

No. This is a parts catalog — it lists components, not repair procedures. You still need the Terex service manual for torque specs and assembly steps. The two complement each other.

Don’t let a missing part number stall your truck. The factory book gives you the numbers, the indexes, and the warranty terms. Stop guessing. Access the Factory Manual.
