Takeuchi TB175 Parts Catalog

I have been under excavator cabs for 28 years, and there is nothing worse than a stripped thread or a wrong gasket because you guessed at a part number. This Takeuchi TB175 Parts Catalog is the original factory document, not a scanned reprint off some third-party site. It runs 631 pages, covers serial number 17530001 and up, and comes direct from Takeuchi’s own research system. If you are ordering parts for a TB175, you want this on the bench, not a generic list from a parts counter clerk who reads from a different database.

The catalog breaks down every assembly — travel lever, swing pedal, hydraulic cylinder groups, undercarriage, you name it. Each exploded view shows the exact part number, the quantity per assembly, and interchangeability marks. That last part saves you phone calls: the manual tells you if an old part can swap with a new revision, marked with (H) or (L) codes. No guessing.

How the Parts Manual Is Organized

Open the PDF and the first few pages explain the symbols and conventions in English and Japanese. You get a table of contents broken by major systems — engine, cooling, hydraulic, electrical, frame. Each system has its own section with a parts illustration and a numbered list. The part numbers are Takeuchi factory numbers, not aftermarket substitutes. If you see an “X” prefix before the part number, that part is not sold separately — meaning you buy the whole assembly. That alone keeps you from ordering a $5 seal when you need the $400 cylinder.

Page numbers are printed on each spread, and the revision number is in the corner so you know you have the latest update. I have seen guys buy old reprints and then find the part number was superseded. Not here.

Reading the Part Numbers and Interchangeability

The manual uses a symbol system: ★ for a sub-assembly, ● for a component that itself breaks down further. The (H) and (L) marks in the interchangeable column tell you if a part with a different suffix can replace the original — but only within the same letter group. For example, if the column shows (H) A and (H) a, those two parts interchange as a set. Miss that detail and you order a single part that won’t mate with its neighbor. That is the kind of detail you pay for in an OEM catalog. Takeuchi TB175 Workshop Manual includes the service procedures, but this parts catalog is the companion you need when the wrench actually fits.

Ordering Parts: What You Must Tell the Dealer

Page 3 of the manual lists exactly what the dealer needs: machine model, serial number, part number, description, quantity. Write it down on your work order before you call. I have wasted hours because a tech gave only the model and said “the doohickey on the left side.” The TB175 has left and right defined from the operator seat facing forward — the manual says that on page 4. Stick to that and you get the right part the first time. Takeuchi TB175 Service Manual covers the repair steps, but for ordering, this catalog is your checklist.

Why OEM Beats Aftermarket Parts Lists

Aftermarket catalogs often use generic part numbers or group multiple models together. This one is serial-number specific: TB175 (P-TB175BBE) BL7Z002-2. The illustrations are drawn from Takeuchi’s engineering data, not reverse-engineered. When you need a travel lever or swing pedal assembly, the exploded view shows every washer and clip. You count the quantity — if the manual says AR (as required), you decide how many. That is real data, not a guess. Check the Automotive Industry Overview on Wikipedia if you want to see how far off generic parts can be; I have seen guys order a pump seal that fit a different model and lose a day. For the same reason, the Automotive Industry Overview shows why OEM spec matters even on construction equipment.

This Catalog and the TB175 Work Together

If you already own a Takeuchi TB175, the serial number determines which catalog version you need. This one covers from 17530001. Earlier machines may have different part numbers. Always check the index at the front — the manual lists the book number BL7Z002-2. Pair it with the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual if you also run a TL26, but the TB175 is its own beast. The parts catalog gives you the drawing reference number (符号) that matches the illustrations. You do not need to be a pro to read it — just follow the key on page 2.

FAQ

Does this parts catalog include torque specs or service procedures?

No. This is a parts catalog, not a service manual. It only lists part numbers, quantities, interchangeability, and exploded views. For service specs buy the workshop manual.

Can I use this to order parts for a TB175 with a serial number before 17530001?

No.

What if I need a part number that isn’t listed? Should I assume it’s discontinued?

If a part number appears with an “X” prefix it means that individual component is not sold separately — you must buy the parent assembly. If the number is simply missing, double-check your serial number range. The catalog covers S/N 17530001 and up. For older machines, you need a different catalog. Do not assume it is discontinued until you confirm with Takeuchi dealer support and cross-reference the illustration group. The manual often shows optional or field-installed parts under separate notes — read the note box next to the illustration. Missing a note is how you end up with a box of wrong gaskets.

Is this the same PDF that dealers use?

Yes. This is a direct copy of the OEM factory parts catalog in PDF format, identical to what Takeuchi provides to their authorized dealers. No alterations, no aftermarket logos.

If you are tired of calling the dealer three times because your part number does not match the drawing, get the factory data. Access the Factory Manual and keep it on your laptop or tablet in the shop. 631 pages of verified OEM part numbers — that is the only way to order parts for a TB175 and be sure they fit.
