Takeuchi TB15, TB120 Parts Catalog – 310 Pages of OEM Parts Data

You have the machine apart, spread across the shop floor, and the aftermarket parts list has a number that doesn’t match anything on the planet. That is the exact moment you need the Takeuchi TB15, TB120 Parts Catalog – the real factory print, not a rehash. This is a 310-page OEM document that gives you exploded views and part numbers straight from Takeuchi. No translation errors, no “cross-reference” nonsense. If you are ordering a hydraulic hose or an engine gasket, the number on page 27 is the number you write on the order form.

Every one of these 310 pages came from the original factory file, scanned from a binder that sat on a dealer counter. The table of contents shows two main sections: TB15 PARTS 1997 and TB15 ENGINE PARTS. That engine section alone is worth the access – we have all used a generic diagram that leaves out the oil cooler bracket or the exact bolt length. Not here.

TB15 ENGINE PARTS: What This Catalog Covers

Open to the engine section and you get exploded views of the block, head, cooling system, and fuel delivery components. Each illustration has an item number that ties directly to the part list below it. The part list includes the description, quantity per machine, and the Takeuchi part number. Need a piston ring set for a TB15 built after serial number 00543? That information is laid out in the same format as page 3 of the manual: part number, description, quantity. No guesswork.

This section covers the complete power unit – from the air cleaner housing down to the flywheel housing bolts. The OEM print shows fastener locations that third-party catalogs often omit. If you are rebuilding an engine, you want the factory exploded view so you know the order of washers and spacers.

What Is the Correct Machine Orientation?

Flip to page 2 (the “How to read the parts catalogue” page) and you will see how Takeuchi defines front, rear, right, and left. For the upper machinery, the front is the side with the dozer blade. For the lower machinery, the travel device side is the rear. This matters when you order a track roller or a final drive seal – ordering the wrong side means a week of downtime. The manual spells this out with a diagram, not a paragraph of text.

Do not ignore that page. I have seen a shop order eight left-hand rollers because the parts guy guessed. The catalog sets the orientation so you get the exact part for the exact position.

3 Reasons to Use the OEM Takeuchi Parts Catalog

Aftermarket parts catalogs reuse old artwork and change part numbers without notice. This Parts Catalog from Takeuchi gives you three things:
First, the exploded views match the physical layout of the machine – every bracket, hose clamp, and seal is drawn where it actually sits.
Second, the part numbers are the current factory numbers. Call your Takeuchi dealer and read the number off the page; they will ship the right part.
Third, the quantity column tells you exactly how many of each item you need for one machine. No ordering one when you need four.

If you work on both TB15 and TB120 excavators, this single catalog covers both models. That is 310 pages of shared parts data in one binder. The serial number break is S/N00543 & After – so if your machine falls in that range, the parts in this book are current.

Ordering Parts: The Manual’s Procedure on Page 1

Page 1 gives the example: TB-15 2305 19081-09095 hose 2pcs. – model, serial number, part number, description, quantity. That is the format Takeuchi expects when you call or email a dealer. The manual explicitly tells you to state the model and serial number along with the part number. Miss that step and a dealer can ship the wrong component, especially on machines that had running changes.

The catalog also notes assembly items. If a part number has a “0-” prefix, it is an assembly, and the sub parts are listed below it. For example, a cylinder assembly will show the seals and piston separately. That is useful if you only need a seal kit, not the whole cylinder.

Compare: OEM vs Aftermarket Parts Lists

Take the engine section again. Aftermarket catalogs might list a “gasket set” without breaking down each gasket. This catalog shows each individual gasket with its own part number – head gasket, intake gasket, exhaust gasket, valve cover gasket. One wrong aftermarket number and you are pulling the head again. The OEM list eliminates that risk.

Look at the lower machinery: aftermarket drawings sometimes merge left and right travel motors into one image. The Takeuchi catalog assigns separate item numbers to left and right, with (L.H) and (R.H) suffixes. That is the level of detail that keeps a job on schedule.

For the hydraulic system, the exploded views include O-rings, backup rings, and fittings. Those small parts are the ones that leak and the ones aftermarket catalogs skip. This manual does not skip anything.

Frequently Asked Questions

Does this Parts Catalog include torque specs for the TB15 engine?

No. This is a parts catalog, not a service manual. It lists part numbers and quantities. Torque values are in the factory service manual. If you need torque specs, look for the Takeuchi TB15 Operators Manual – Factory Specs for Compact Excavator instead.

Will the part numbers work for a TB120 with serial number 01000?

The catalog covers S/N00543 & After for both TB15 and TB120. For machines before that break, some parts may differ. You can compare the exploded view with your machine or contact a dealer. If your serial is inside the range, the numbers are correct. Also check the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual if you have a TL26 model.
