Caterpillar TH336, TH337, TH406, TH407 2010 Parts Catalog

You pulled a transmission out of a TH406 last week and the aftermarket parts list gave you a seal that was six millimeters too wide. Now the job sits, customer calls every hour, and you’re burning time cross-referencing three different websites. I’ve seen it a hundred times. The only way around that is a factory Caterpillar TH336, TH337, TH406, TH407 2010 Parts Catalog—the same binder the dealer parts counter uses. This isn’t a reprint or a third-party compilation. This is the actual 386-page PDF that came out of Caterpillar in 2010, with serial number breaks, effectivity dates, and figure callouts that match the real hardware.

Let me walk you through why this file belongs on your shop tablet right now.

Section 4 – Engine & Attaching Parts

Section 4 covers the CAT engine itself, fuel lines, radiator, air cleaner, muffler, block heater, and both hydraulic and pneumatic reversing fans. Every part in Figure 4-2 has a Caterpillar part number tied to a specific serial range. If you’re ordering a fuel injector line for a TH337 with S/N TDF00100 and after, you need the exact part from Figure 4-3. One wrong digit on the casting code and the line won’t clock right. The manual shows the installation grouping, so you can spot which clamps and brackets are included. Page 4-1 starts the section; you don’t have to guess.

What Does Section 2 Cover?

Section 2 is the boom assembly. Figures 2-1 through 2-8 break down the first and second boom sections, quick couplers, JD coupler, JCB coupler (manual and hydraulic), and Manitou coupler. If your customer’s TH406 has a JCB coupler retrofit, you need Figure 2-7. The parts catalog lists every pin, bushing, and hose fitting by number. Aftermarket coupler kits often skip the retaining ring or use a wrong seal. With this manual you order the exact Caterpillar service kit.

5 Drive Train Systems You Need to Identify

Section 5 dives into the front and rear axles—housing, swivel, steering cylinder, bevel gear set, differential, double u-joint, brakes, wheel hub, final reduction, brake caliper. That’s twelve figures just for the front axle. If you’re rebuilding a front brake caliper on a TH407, Figure 5-10 gives you the piston seal, dust boot, and guide pin part numbers. The rear axle has its own set of figures (5-11 through 5-18). I’ve seen guys order the wrong brake pad because they used a generic cross-reference. Don’t be that guy.

Use the Effectivity Page Before You Order Anything

Page 3 of the PDF shows the effectivity history: original issue in February 2008, then revisions B through H up to November 30, 2010. This manual covers S/N TDE00100 & after (TH336), TDF00100 & after (TH337), TBX00100 & after (TH406), and TBY00100 & after (TH407). If your machine’s serial falls before those ranges, this catalog won’t match. That’s why the effectivity page exists—to save you from ordering parts for the wrong generation. Check it before you spend a dime.

Why a Factory Parts Catalog Beats a Third-Party List

Aftermarket parts aggregators pull data from old paper catalogs and often mix up revisions. I’ve seen a TH336 hydraulic hitch part listed under a TH406 because someone merged the PDFs wrong. This document is the original Caterpillar release. The figure numbers, callouts, and part numbers are verified by the manufacturer. When you open Section 8 (Hydraulic Circuits), the supply circuit, dump circuit, steer select valve, service brake, lift cylinder, and auxiliary hydraulics are all diagrammed with the same clarity as the dealer service system. No translation errors.

Frequently Asked Questions

Can I use this manual to order parts for a TH406 with serial number before TBX00100?

No. This manual only applies to S/N TBX00100 and after.

Does this parts catalog include wiring diagrams?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and illustrations for every component in the frame, boom, attachments, engine, drivetrain, cab, controls, and hydraulics. If you need electrical schematics, you’ll need the corresponding service manual for your serial range. The parts catalog focuses on what you order, not how to diagnose or repair.
