Takeuchi TB175 Parts Catalog – OEM Factory Parts Breakdown for Compact Excavator

If you’ve ever ordered a part for a Takeuchi TB175 Parts Catalog from a generic online listing and ended up with a bracket that doesn’t bolt to the frame, you know the pain. The guy at the parts counter reads a number, you read a number, and somehow the left-hand travel motor arrives as a right-hand. That waste of time costs money. I’ve been under enough excavators to tell you: without the factory parts breakdown, you’re guessing. This is the OEM Takeuchi document – Book No. BL3Z005, covering serial number 17510003 and up. 818 pages of exploded diagrams, part numbers, quantities, and compatibility codes. No aftermarket shortcuts, no photocopied blur.

Takeuchi TB175 Parts Catalog – What You Get with 818 Pages

Open the PDF and the first thing you see is the Index, then a detailed “How to read the parts manual” section in English and Japanese. That’s not filler – it explains the reference numbers, the (L) and (R) compatibility marks, and how to decode the assembly symbols. After that, the catalog splits into eight sections. Every section lists parts by assembly group, with a reference diagram and a table of part numbers, descriptions, quantities, and serial number applicability. The two engine subsections cover the 4TNE98-TBZ and 4TNV98-VTBZ power units, each with its own parts index. That’s the level of detail you need when a fuel injection pump seal goes and you need to confirm the gasket kit number.

1 UNDERCARRIAGE – Track and Frame Parts

Undercarriage is where most wear happens. This chapter covers track chains, sprockets, rollers, idlers, and the track frame assembly. For each component the catalog shows the exact OEM part number and the quantity required per machine. If you’re rebuilding a track, you’ll see the compatibility notes – which rollers supersede older ones, and which bolts come with the sprocket kit. No aftermarket cross-reference that might be off by a thread pitch. Factory spec, period.

3 ENGINE & ELECTRICAL SYSTEM – Critical Sections for Repairs

The Engine and Electrical sections live together in Chapter 3. For the engine, you get the full parts breakdown for the 4TNE98-TBZ and 4TNV98-VTBZ – cylinder head, pistons, injection pump, alternator, starter. The electrical portion covers the wiring harness, fuse box, sensors, and switches. If you’re chasing a no-start condition, having the factory part numbers for the ECM relay or the crank position sensor saves an afternoon of cross-referencing. The manual even lists the serial number ranges where a part applies, so you don’t order a pre-update part for a post-update machine.

Why Factory Documentation Outranks Aftermarket Copies

I’ve seen aftermarket parts catalogs that claim to cover the TB175 but use generic drawings and leave out the (L) and (R) compatibility indicators. This is an original Takeuchi publication – printed from the same source the dealer uses. The page headers show the book number and serial number range. Every exploded view has reference numbers that tie directly to the parts table. If a part has a “★” symbol, the table tells you it’s an assembly with sub-components listed below. You won’t find that in a third-party reprint. For a Automotive Industry Overview, OEM documentation is the standard. This catalog meets that standard.

Using the Parts Index and Ordering System

At the back of the manual there’s a Parts Index that lists every part number alphabetically with a page reference. Need to find a hydraulic pump seal? Look up the part number in the index, flip to the page, and see it in the assembly. The ordering instructions (pages 3–5 in the PDF) tell you exactly what information the dealer needs: machine model, serial number, part number, part name, and quantity. Write it down before you call. It beats the back-and-forth of “Does that include the O-ring?”.

The hydraulic sections – 4 HYDRAULIC PIPNG & TANK and 8 HYDRAULIC DEVICE – cover everything from the main pump to the swing motor and cylinders. If you’re replacing a hose assembly, the diagram shows the fitting orientation and the correct part number for the complete hose, not just the tube. That eliminates the guesswork when you’re ordering from a supply house.

Who Should Buy This Takeuchi TB175 Parts Catalog

Home-garage mechanics who maintain their own compact excavator. Fleet managers who need to stock critical spares. Techs who rebuild undercarriages or swap engines. If you’ve ever had a machine down because the wrong seal kit arrived, this catalog is your insurance. It’s also the correct companion to the Takeuchi TB175 Workshop Manual for repair procedures – the parts catalog tells you what to order, the workshop manual tells you how to install it. Pair it with the Takeuchi TB175 Service Manual for torque specs and diagnostics. For a smaller machine, the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual follows the same layout.

Access the Factory Manual – get the exact PDF that Takeuchi issued, with all 818 pages, bookmarks, and searchable text. No reprints, no missing pages, no aftermarket nonsense.

Is this a service repair manual or a parts catalog?

This is a parts catalog. It lists part numbers, quantities, and exploded views. It does not contain repair procedures or torque specs.

Will this manual work for a TB175 with serial number 17509999?

It covers serial number 17510003 and up. For earlier machines, you would need the previous revision. Always verify the serial number range.

What engine models are covered in the catalog?

Two variants: the 4TNE98-TBZ and the 4TNV98-VTBZ. Both have their own dedicated parts index and section within Chapter 3.

Can I use this manual to order parts from a Takeuchi dealer?

Yes. The manual explains the exact information required: machine model, serial number, part number, part name, and quantity. Provide those and the dealer can fulfill the order without delays.
