Takeuchi TB070 Parts Catalog – What You’re Actually Getting

Every time a machine sits because the wrong part showed up, you burn daylight and money. Seen it happen with a TB070 undercarriage job last month. The kid ordered a carrier roller that looked close enough – didn’t match the serial number split. A factory parts catalog kills that crap before it starts. This Takeuchi TB070 Parts Catalog is the original OEM publication, 575 pages, book number PL1-101Z5, covering serial numbers 1703004 through 1705487. No third-party reprints, no aftermarket approximations. You get the exact part numbers Takeuchi stamped into the metal.

What the Table of Contents Actually Tells You

Open to the index and you’ll see every major system broken down by assembly group: UNDERCARRIAGE, TURNTABLE & CONTROL LEVER, ENGINE & ELECTRICAL SYSTEM, HYDRAULIC PIPING & TANK, COVER & CAB, HOE ATTACHMENT, DECAL & TOOL. Each section splits further by serial number ranges because Takeuchi made running changes. Example – the lower piping with valve has a separate entry for machines built before and after serial 1703949. If you don’t respect those splits, you’re ordering parts that won’t bolt up. Page 1 gives the full model and serial range so you can confirm fitment before you even start flipping.

Hydraulic Valve and Accessories – Why the Splits Matter

The valve section alone has six different sub‑sections depending on whether the machine has second auxiliary lines and when it was built. Valve & Accessories (with the second auxiliary lines) covers 1703004–1704085, then a two‑part split for 1704086–on. That’s the kind of detail you need when you’re replacing a spool or seal kit. Generic parts catalogs lump everything together and leave you holding a valve that doesn’t stroke. This manual shows each valve assembly with its own part number, quantity, and compatibility note. There’s even an Emergency Shut‑Off Valve section if you’re chasing a relief issue.

3 Sections That Save You from a Parts-Ordering Headache

First – the UNDERCARRIAGE. Crawler belt, carrier roller, track roller, front idler, track adjuster, travel device, slew bearing, swivel joint. Each component has its own exploded diagram with callouts matching part numbers. Second – the ENGINE & ELECTRICAL SYSTEM. It includes engine accessories, control boxes, electrical harness splits by serial number, battery, side light, maintenance light socket, even the radio and air conditioner. Third – the HOE ATTACHMENT. Boom (two serial breaks), arm, long arm, telescopic arm, bucket, bucket for U.S.A., auxiliary line. If you’re fabricating or swapping buckets, the part numbers for bucket pins and bushings are right there. No measuring needed.

Who Should Buy This – and Who Shouldn’t

This catalog is for the guy who owns a TB070 and doesn’t trust the dealer to cross‑reference his machine serial every time. It’s for the shop that bills by the job and can’t afford a “sorry, wrong part” four days later. If you are a beginner learning to order parts for construction equipment, this manual teaches you how to read a factory parts book – the numbering system, compatibility codes (H/L), and how serial breaks work. Takeuchi TB070 Parts Catalog is the foundation. Pair it with a workshop manual for torque specs and repair steps – check out the Takeuchi TB070 2000 Workshop Manual – Section: Vi. Engine and Takeuchi TB070 2000 Workshop Manual – Section: Engine if you’re going deeper into the engine side. For general automotive repair context, the Automotive Industry Overview and Automotive Industry Overview provide background, but this catalog is specific to Takeuchi.

Source Validity – OEM vs. Aftermarket Parts Lists

Aftermarket parts catalogs are garbage for serial‑split machines. They consolidate part numbers to reduce printing cost and you wind up with the wrong track adjuster or a valve that doesn’t fit the subplate. This Parts Catalog is scanned from the original Takeuchi print. The page layout matches the dealer book – Japanese, English, French, German text in the same document because Takeuchi sells globally. The part numbers are the same ones the factory uses. If a part is not sold separately, the number is preceded by an ‘X’. That information is critical when you’re trying to decide whether to buy a hose assembly or crimp your own. The compatibility codes (H and L) tell you if a superseded part can replace an older one. No aftermarket book gives you that granularity.

Does this Parts Catalog include torque specs or repair procedures?

No. This is a parts identification manual. It lists every component, its part number, quantity, and compatibility. Torque values and disassembly steps are in the workshop manual. Get both if you’re doing a full rebuild.

How do I find the right part for my machine if the serial number falls between two ranges listed in the TOC?

Check the serial number on the machine plate first. The catalog covers 1703004 to 1705487. For example, the lower piping with valve has separate pages for 1703004–1703949 and 1703950–on. If your serial is 1704000, you use the later section. Each section heading shows the applicable range. If a part applies to all serials, no range is listed. Cross‑reference the part number back against the diagram to confirm the assembly group. If you still can’t match, look for the “Note” row on that page – sometimes Takeuchi printed a service update note. The index at page 0 lists every major group with its page number, so start there.

You’ve got a 575‑page factory document that tells you exactly what Takeuchi says fits your machine. Stop wasting time chasing aftermarket catalogs that collapse serial splits. Access the Factory Manual and get the right part the first time.
