Takeuchi TB175W Parts Catalog

I’ve had enough of guys showing up at the parts counter with a hand-drawn sketch and a vague description. Wastes your time, my time, and leaves a machine sitting on blocks. That’s why you need the Takeuchi TB175W Parts Catalog – the factory-issued book that gives you real part numbers, not aftermarket guesses. 691 pages of exploded views, hardware callouts, and machine-specific compatibility tables. No translation errors, no fudged dimensions.

Every TB175W built from serial number 17520003 onward is covered in this original OEM document. You get the same information Takeuchi dealerships use. That means you can order the correct hydraulic line, the right seal kit, or the exact lever assembly on the first try.

How to Read This Parts Manual

Open it up and the first few pages explain exactly how Takeuchi lays out their numbering. Each part gets a unique part number. If there’s an “X” in front of that number, the part is not sold separately – you have to order the assembly. The manual uses asterisks to show sub-assemblies: one star means it’s part of a bigger assembly, two stars mean it’s a sub‑assembly inside that. You’ll also see (H) for right side, (L) for left. Once you learn the system, you can tear through part lookups in seconds.

Ordering Parts Correctly

You wouldn’t walk into a dealer without a VIN on a car – same here. You need the machine serial number (S/N) from the plate. This catalog lists every part with the specific serial number range it fits. Order a swing pedal for a 17510003 and it won’t fit a 17520003. The manual prints that distinction right on the illustration. Don’t ignore it. Also mind the quantity column – it shows the number needed per machine unless you’re looking at a sub‑assembly page, where it shows quantity per single part.

Right, Left, Front, Rear? Get It Straight

If you’ve ever argued with a tech over which side the final drive goes on, this section ends that debate. The manual defines directions from the operator seat facing forward. Right side is operator’s right (H), left side is operator’s left (L). Everything in the catalog follows that convention. Printed right there on page 5 of the book. No ambiguity.

Compatibility and Interchangeability Notes

Takeuchi marks when a new part number supersedes an old one. You’ll see (H) next to a part number meaning it replaces the item listed in the row above. If a whole assembly changes, they use paired uppercase and lowercase letters – for example, an “A” group and an “a” group. That means you can swap the entire group as a unit. This alone saves you from ordering five parts that don’t mate together.

691 Pages of Factory Parts Data

This isn’t a condensed aftermarket pamphlet. 691 pages – every assembly from the engine mounts to the swing pedal linkage. Each page index references the book number BW2Z008-1 and serial range. The Takeuchi TB175W Workshop Manual handles the repair procedures, but this parts catalog is what you pull when something breaks and you need to source the replacement. Pair it with the Takeuchi TB175W Parts Catalog itself (yes, that’s this one) and the Takeuchi TB175W User Manual – OEM Operator’s Guide for Hydraulic Excavator to complete your reference set.

FAQ

Does this catalog list torque specs?

No. This is a parts catalog only. Torque values are in the workshop manual.

How do I use the interchangeability letters when ordering from a dealer?

Look at the compatibility column. If you see a capital letter (like “A”) next to an old part and a lowercase “a” next to a new part, those two groups are directly interchangeable as assemblies. Tell the parts counter “I need the new group ‘a’ to replace group ‘A’.” Make sure your dealer understands the letter pairing – they’ll cross‑reference it using Takeuchi’s system. If you just give the part number without noting the group, you might get the old stock that doesn’t align. Always check the serial number applicability line at the top of the page. If no serial number is listed, that part fits all machines covered by the catalog. For anything after 17520003, stick with the parts that show no restriction.

I’ve seen too many good jobs go sideways because someone trusted a third‑party parts list. The OEM factory document eliminates that risk. Whether you’re a fleet mechanic or an owner‑operator, this catalog puts the right numbers in your hand. The same quality principles that govern heavy equipment manufacturing – documented in the Automotive Industry Overview – apply here: use accurate specifications, not approximations.
