Takeuchi TB007 Parts Catalog – Order the Right Part the First Time

You are elbow-deep in a Takeuchi TB007 undercarriage rebuild, and you pulled a track adjuster cartridge that looks nothing like the aftermarket cross-reference you bought last week. Now the machine sits, the customer is waiting, and you are stuck with a pile of wrong seals. I have seen that exact scene more times than I care to count. The fix is not guessing – it is using the Takeuchi TB007 Parts Catalog that came from the factory, not a third-party rehash. This is the official OEM file, Book No. PB4-101Z6, covering serial range 1073001–1074744. 287 pages of exploded diagrams and part numbers you can trust. No shortcuts.

What the Parts Catalog Covers

The table of contents is laid out by machine section, not by some generic category. You get undercarriage, turntable and control levers, engine and electrical system, hydraulic piping and tank, cover and cab, hoe attachment, decals and tools, hydraulic devices, and two separate engine subsections (2TN66L and 2TNE68). Each section breaks down into specific assemblies. For example, the Undercarriage section includes lower frame, crawler belt, track roller, front idler, track adjuster, travel device, dozer blade, and lower piping. The Hydraulic Device section lists swivel joint, control valves, stop valve, all cylinders, travel motor, slew motor, and hydraulic pump. If you need a bucket cylinder seal kit, the part number is in there – but you have to look under the correct serial number split because Takeuchi changed components at certain machine breakpoints.

The catalog covers serial splits for the US market, Japan, and JCB pattern variants. The electrical system section is split three ways: 3001–3463, 3464–4339, and 4340–. Miss that, and you order a harness that does not reach. That is why you need this catalog. Related: Takeuchi TB007 Workshop Manual has the repair procedures, but the parts catalog is what keeps you from buying the wrong part in the first place.

Who Needs This Catalog

If you own a TB007 compact excavator and do maintenance or repair yourself, you need this. Same if you run a shop that sees one of these machines every few months. The DIY crowd trying to order parts over the phone without part numbers ends up with a box of wrong pieces. Professional mechanics bill by the hour – wasting time chasing aftermarket catalogs that skip serial splits costs real money. Workshop owners should have this on every tech’s tablet so they stop tying up the parts counter while the clock runs. The part number is the single most expensive thing you can get wrong on a job. This catalog fixes that.

OEM vs Aftermarket – Why It Matters

Aftermarket parts catalogs renumber parts to fit their inventory. They generalize across serial ranges. Takeuchi did not build the TB007 the same way for its entire production run. The decal section alone has separate listings for Japan, English US, German, French, Italian, and even a specific US Takeuchi decal set for later machines. An aftermarket book lumps them all under one part number. That is how you get a warning decal in Italian on a machine sold in Texas. The OEM catalog respects the serial number breaks – see Automotive Industry Overview for context on why factory documentation is the gold standard. This file is a direct scan of the original Takeuchi publication, not a reprint with lost data.

How to Read the Exploded Diagrams

Page 3 of the catalog explains the format. Upper half of each page shows the exploded diagram; lower half holds the parts list. The diagram orients the assembly in the same position as the general drawing of the machine. Front and rear for the lower machine: the dozer blade end is front, the travel equipment end is rear. For the upper machine, front/rear/left/right is from the operator’s seated position. Every part has an item number, a genuine Takeuchi part number, description, quantity, and a serial number column. If the part number has an “x” prefix, it is not sold separately – you buy the assembly. The parts list example on page 4 shows a body (05441-01100) and a shaft, drum (05441-01300) with quantities. Match your machine’s serial number to the correct page. That is all there is to it – if you follow the procedure. Skip the step where you verify your serial number against the header on the page, and you order a part that fits a different breakpoint.

Undercarriage and Hydraulic Sections – Real Data

The Undercarriage chapter lists the track adjuster, front idler, track roller, and crawler belt assemblies with exact part numbers per serial range. The hydraulic device section covers the swivel joint, control valves (split into Control Valve 1 and Control Valve 2), stop valve, boom cylinder, arm cylinder, bucket cylinder, dozer blade cylinder, swing cylinder, and a spanner cylinder. Travel motor and slew motor are also listed. If you need the hydraulic pump, it is in that section. Each component has its own exploded view – you can see exactly which o-ring, seal, or fitting belongs where. No guesswork. For the engine, you have two separate engine catalogs within the same file: one for 2TN66L-UTBA (serial 1073001-1074339) and one for 2TNE68-ETB. Each engine sub-catalog includes cylinder block, head, camshaft, crankshaft, fuel injection pump, governor, starter, alternator, and gasket sets. The gasket set is listed as optional – part numbers are there.

Frequently Asked Questions

Can I use this catalog to find repair torque specs?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and serial ranges. Torque values and repair procedures are in the workshop manual. If you need both, get the Takeuchi TB007 1998 Workshop Manual – Section: Iv. Hydraulic Units for torque specs and disassembly steps.

Does the catalog cover all TB007 serial numbers?

It covers serial numbers 1073001–1074744. If your machine falls outside that range, you need a different edition. The serial number splits are printed on the page headers – always check your machine’s serial before ordering parts. For machines after 4340, there are separate decal and electrical sections. The catalog uses exact breakpoints, not approximations.
