Takeuchi TB175, TB180 Parts Catalog – 676 Pages of Factory Part Numbers

I’ve seen too many machines sidelined because someone ordered a hydraulic pump seal kit by serial number guess and got the wrong valve. You don’t have that kind of time. The Takeuchi TB175, TB180 Parts Catalog is a 676-page OEM document that gives you the exact part number, description, quantity, and interchange code for every component on these compact excavators. No aftermarket repackaging, no re-drawn illustrations with missing callouts. This is the book Takeuchi dealers use when you call in with a serial number.

Engine-Related Parts: What You’ll Find in Section 1

The catalog splits into ten numbered sections. Section 1 covers engine-related parts. If you need a cylinder head gasket, fuel injection pump, or any valve train component for the TB175 or TB180, you start here. The engine and accessories subsection alone spans three pages (page 45 through page 47 in the detailed index). Each illustration shows every bolt, seal, and bracket with a reference number. The parts list next to the drawing gives you the OEM part number, the quantity used per machine, and a code that tells you if that part supersedes an older number. You don’t guess – you read the exploded view and order exactly what fits your serial number range.

Hydraulic Pump & Control Valve – Factory Valve Identification

Section 2 is where you find the hydraulic pump and control valve group. If a control valve spool sticks or a pump seal leaks, you need the exact valve part number, not a “universal” replacement. This catalog shows every valve body, spool, spring, and plug as a separate line item. The interchange column uses letters (H, L) to indicate forward or backward compatibility with earlier serial number breaks. I’ve torqued enough hydraulic fittings to tell you: using the wrong O-ring or back-up ring because you guessed at the part number leads to a blown seal and a $2000 pump rebuild. This catalog prevents that.

Identify the Right Valve – Factory Specs Only

Valve identification is a common headache. The TB175 and TB180 use different control valve configurations depending on the serial number prefix. Section 2 (Hydraulic Pump & Control Valve) lists every valve sub-assembly with its own part number. You cross-reference your machine’s serial number against the “SERIAL NO.” column on each page. If the serial number falls between 17510003 and 17511262, you get one valve group; above 17511263, you get another. The catalog also flags parts marked with “X” – those are not sold separately. That keeps you from ordering a component you can’t buy alone. The manual tells you upfront.

676 Pages of Part Numbers – What You Get

This catalog runs exactly 676 pages. It covers the TB175 and TB180 from serial number 17510003 up. The table of contents (page 2 of the PDF) lists ten main sections: Engine-Related Parts, Hydraulic Pump & Control Valve, Travel Motor & Swing Device, Chassis & Track Parts, Boom/Stick/Arm/Bucket, Cab & Instrument, Operator’s Seat & Cover, Body Frame & Counter Weight, Hydraulic Tank & Pipe, and Others. Each section breaks into multiple sub-sections with individual exploded diagrams. For example, the boom, stick, arm, and bucket section (section 5) contains multiple views for standard boom, two-piece boom, and various control pattern piping configurations. Every part number is tied to a specific serial number range. If you own a TB175 or TB180, this book covers it.

Boom, Stick, Arm & Bucket Section – Detailed Exploded Views

Section 5 is one of the thickest parts of the catalog. It covers the entire front attachment. You get separate pages for the boom swing, stick cylinders, bucket linkage, and pins. The illustrations show every shim, seal, and bushing. If you’re rebuilding the stick cylinder, you find the piston seal kit part number directly from the diagram. No need to measure the rod diameter and guess which aftermarket kit matches. The OEM part number is right there, along with the quantity used. The catalog also includes piping diagrams for the operation levers (multiple patterns: ISO, JCB, A-B, multi-pattern) – all with their own part number callouts. That saves you from ordering a hose assembly that’s six inches too short.

Source Authenticity: OEM Takeuchi vs Aftermarket Parts Lists

Aftermarket parts catalogs often redraw the illustrations, drop the interchange codes, and omit the serial number break information. This one is an original Takeuchi publication. The part numbers are the same ones stamped on the components at the factory. When you order a part using this catalog, the dealer’s computer recognizes the number immediately. There’s no cross-referencing required. If you want to see how the automotive industry handles OEM documentation standards, you can read the Automotive Industry Overview. But for Takeuchi equipment, this catalog is the standard. Automotive Industry Overview also notes that OEM documentation reduces error rates – this catalog proves it.

Frequently Asked Questions

Does this catalog include torque specs for the engine head bolts?

No. This is a parts catalog, not a service manual. It lists part numbers, quantities, and interchange codes. You need the separate Takeuchi TB175 service manual for torque values and repair procedures.

Will this catalog work for a TB180 with serial number 17510003?

Yes. The catalog covers serial numbers from 17510003 up. If your machine falls within that range, every part listed applies.

How do I read the interchange codes in the parts list?

Single parts have (H) meaning immediately replaceable with the higher-line item, and (L) meaning replaceable with the lower-line item. For grouped parts, uppercase and lowercase letters form a set; (H) and (L) indicate group interchangeability. See page 4 of the catalog for the full legend.

Can I use this catalog to order parts for a Takeuchi TL26?

No. This catalog is specific to the TB175 and TB180 models. The Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual is a separate publication. Always match the catalog to your machine model.
