Caterpillar TH336, TH337, TH406, TH407 2010 Parts Catalog

If you have ever sat on a job site waiting for a replacement hydraulic fitting because some PDF you obtained from a forum had the wrong part number for your TH337’s boom cylinder, you already know why owning the real factory catalog matters. I have been an ASE Master Technician for 28 years, and I have watched shop foremen waste three hours chasing a misprinted aftermarket reference. This is not that. This is the actual Caterpillar TH336, TH337, TH406, TH407 2010 Parts Catalog – the same book Caterpillar dealers use to punch in orders. 352 pages of exploded-view drawings, OEM part numbers, and supersession data.

You need to identify a specific seal in the swivel housing on a TH406? The drawing on page 5-3 will show you exactly which O‑ring and backup ring belong there. No guesswork. No cross-referencing three different websites. The manual was revised six times between February 2008 and April 2010, so the information on the fuel line installation (Figure 4-3) or the reversing fan (Figure 4-9) reflects the current production specs. That matters when a customer’s machine is down and you are ordering parts against a serial number.

Why an OEM Parts Catalog Beats Aftermarket

Aftermarket catalogs often crop illustrations or skip figures. This factory file contains every figure from Section 1 (Frame & Attaching Parts) through Section 9 (Hydraulic Components). Nine sections. 80+ figures. The main control valve breakdown in Figure 9-6 is something you will not find in a generic parts list. When you need a part for the tilt cylinder on a TH336, you go to Figure 9-3 and get the exact Caterpillar part number – not a ‘compatible’ item that might have a different thread pitch. I have seen that mistake cost a shop a blown seal and a pissed-off customer.

Look at Section 4 – Engine & Attaching Parts. It starts on page 4-1 and includes ten figures covering the CAT engine, fuel lines, radiator, air cleaner, muffler, block heater, and both hydraulic and pneumatic reversing fans. You want to replace the fuel tank on a TH407? Get the tank part number from Figure 4-4 and move on. No flipping through unrelated material.

Section-by-Section Breakdown

Here is what the 352 pages actually contain, so you know you are buying a real working document:

• Section 1 – Frame & Attaching Parts: Eight figures covering shrouding, engine pod installation, axle and wheel mounting, retrieval hitch, pin hitch, auto hitch, hydraulic hitch, and fixed position hitch.
• Section 2 – Boom: Boom assembly, first and second boom sections, quick coupler, JD coupler, boom prop, and coupler installations from JCB and Manitou.
• Section 3 – Attachments: Carriage, forks, side shift, rotate/side tilt carriages, buckets (general purpose, multi-purpose, material handling, grapple), truss boom, lifting hook, and swing carriage.
• Section 4 – Engine & Attaching Parts: Engine and transmission installation, CAT engine components, fuel line and tank, radiator, air cleaner, muffler, block heater, and reversing fan (hydraulic and pneumatic).
• Section 5 – Drive Train: Front and rear axle assemblies – housing, swivel, bevel gear, differential, U‑joint, brakes, wheel hub, final reduction, brake caliper, drive shaft, remote grease system, and tire/wheel.
• Section 6 – Cab: Cab installation, interior, door/window, wiper, cab covers/guards, various seat types (vinyl, cloth mechanical, cloth pneumatic), and heater/AC components.
• Section 7 – Controls: Joystick, steering column, accelerator pedal, mechanical handbrake, brake installation.
• Section 8 – Hydraulic Circuits: Supply circuit, dump circuit, steer select valve, service brake, lift cylinder, extend/retract, tilt/tilt compensating, auxiliary hydraulics, rear auxiliary with trailer brakes.
• Section 9 – Hydraulic Components: Lift, extend/retract, tilt, compensation, quick coupler cylinders, and main control valve.

Each figure includes an exploded diagram with callout numbers and a corresponding parts list with quantities and descriptions. The SMCS codes at the front help you navigate if you are used to Caterpillar’s system.

Who Needs This Catalog?

You. If you maintain a fleet of TH336, TH337, TH406, or TH407 telehandlers in a rental yard, construction company, or agriculture operation, this catalog saves you the phone call to the dealer every time you need a part number. It covers serial numbers TDE00100 and after, TDF00100 and after, TBX00100 and after, and TBY00100 and after. If your machine falls in those ranges, every figure applies.

Independent mechanics who take on telescopic handler repairs will find the axle breakdowns in Section 5 particularly useful. The front axle final reduction (Figure 5-9) and rear axle final reduction (Figure 5-18) show the gear sets and bearings separately – something aftermarket tools never give you. And the hydraulic circuit diagrams in Section 8 (page 8-1 and following) let you trace the supply circuit, dump circuit, and service brake circuit without guessing which hose goes where.

For the Caterpillar TH336 TH337 TH406 TH407 2010 Parts Catalog itself, you are buying a direct digital file. No reprints, no scans that lose the fine lines in the drawings. This is the official PDF released by Caterpillar.

Source Authenticity: Factory Print, Not a Copy

The effectivity page shows the manual was originally issued February 15, 2008, and went through six revisions (A through F). The final revision date is April 13, 2010. That means every part number in this catalog was validated by Caterpillar at the time of printing. Aftermarket parts catalogs routinely omit supersession notes or mix up left- and right-hand parts. This one does not. You get the same data a Caterpillar dealership pulls up on their computer.

If you have ever been burned by a third-party manual that listed a part for the TH406 that was actually for the TH414 (which was removed from this manual in revision C), you understand the value of an OEM source. For more context on how the heavy equipment parts industry evolved, see the Automotive Industry Overview. The same principles apply – factory documentation eliminates the guessing.

Frequently Asked Questions

Does this Parts Catalog include repair procedures or torque specs?

No. This is a parts identification manual only. You get exploded diagrams, part numbers, quantities, and descriptions. No torque values, no service steps. You need the separate Caterpillar Service Manual for repair procedures. But if you are ordering parts, this is the only reference you should trust.

Will this work for my TH336 with serial number below TDE00100?

The manual explicitly covers S/N TDE00100 & After, TDF00100 & After, TBX00100 & After, and TBY00100 & After. If your machine predates those break points, some figures may not match. Check the effectivity page for revision history.

How many pages and what format is the file?

352 pages in a single PDF. The file is searchable, and each section is bookmarked. You can jump directly to Figure 5-7 (Front Axle Brakes) or Figure 8-4 (Service Brake) in seconds. No scrolling through hundreds of pages.

Is this a scan or an original digital file?

Original digital file from Caterpillar. No scan artifacts, no missing pages. The line art in the hydraulic circuit diagrams (Section 8) is sharp enough to read the port labels. This is the same file the dealer parts counter uses.

If you have ever ordered a part for a TH407 after cross-referencing a third-party site and ended up with a component that did not fit, you already know the cost of bad information. That downtime adds up. The solution is right here: a factory-verified parts catalog that gives you the exact part number the first time. Access the Factory Manual now and keep your telehandlers in the field instead of in the bay waiting for parts.
