Takeuchi TB070 Parts Catalog

I’ve watched grown men cry over a misordered hydraulic fitting. That’s where Takeuchi TB070 Parts Catalog earns its spot on the bench. This isn’t a third-party summary – it’s the exact parts book Takeuchi sent to dealers, covering serial numbers 1703004 through 1705487. If you need to know which bolt goes in which hole on a 450mm vs. 550mm shoe, you’ll find it on page 1-3. Skip the guesswork and order the right part the first time.

UNDERCARRIAGE: What This Parts Catalog Covers

The TOC starts with the lower frame – page 1-3 gives you the exploded view of frame assy, covers, steps, bolts, and washers with serial number breakouts. For a 450W frame you get part numbers for the step, plug, and four different bolt sizes. The catalog uses the same indexing system as the factory, so when you look up “LOWER FRAME” you see the illustration reference L1-01a-2-D and the exact page. No cross-referencing to some aftermarket spreadsheet.

Engine & Electrical System Breakdown

Chapter 3 covers the Engine – specifically the Nissan BD3004 power unit. You get the full parts breakdown for the engine assembly, including the electrical system. The catalog lists every part number for the alternator, starter, injectors, gaskets – the stuff that fails on a jobsite. If you’re rebuilding a TB070, you want the OEM number for the head gasket, not a generic “fits all” number. That’s in this book.

Does the TB070 Parts Catalog Include Torque Specs?

No. This is a parts catalog, not a service manual. It’s meant to be paired with the factory workshop manual. For torque values on that Nissan BD3004 head bolts or suspension cylinder caps, pick up the Takeuchi TB070 2000 Workshop Manual – Section: Vi. Engine or the Takeuchi TB070 2000 Workshop Manual – Section: Engine. The parts catalog gets you the right part number; the workshop manual tells you how hard to turn it.

450 Pages of Factory Indexed Parts

Four hundred fifty pages, all originally printed by Takeuchi for the TB070 (P-TB070BAB). The index on page 0 lists eight main sections: UNDERCARRIAGE, TURNTABLE & CONTROL LEVER, ENGINE & ELECTRICAL SYSTEM, HYDRAULIC PIPNG & TANK, COVER & CAB, HOE ATTACHMENT, DECAL & TOOL, HYDRAULIC DEVICE, and a dedicated ENGINE section on page 8. Each section has its own reference index and serial number applicability. This is the exact document a dealer would pull up to order a new hydraulic pump seal for your TB070.

Parts Catalog vs. Aftermarket: Know the Difference

Aftermarket parts catalogs combine multiple model years, delete superseded parts, and often misnumber bolts. This OEM parts catalog gives you the “chan.” column – the change code that tells you if a part was replaced by a newer number. For example, the lower frame assembly has a comment “1703932~” – that’s the serial number break. You don’t get that precision from a third-party .pdf.

FAQ

Can I use this parts catalog to identify parts on a TB070 with serial number 1706000?

No. This book covers serial numbers 1703004 through 1705487 only. Engines and frames changed after that range. You need the later edition.

Does the catalog list part numbers for the hydraulic pump or only engine parts?

Yes. Section 4 (HYDRAULIC PIPNG & TANK) and Section 8 (HYDRAULIC DEVICE) cover pumps, valves, and hoses. The catalog includes every item shown in the exploded diagrams with a part number, quantity, and optional notes like “550mm shoe” or “1703932~”.

Are there wiring diagrams in this manual?

No. Wiring diagrams are in the workshop manual. This catalog only lists electrical components (starter, alternator, switches) with their part numbers and positions in the assembly.

How do I know I’m ordering the correct bolt if my machine has aftermarket tracks?

The catalog lists both the 450mm and 550mm shoe variants. Check your machine’s shoe width and serial number, then use the part numbers under the “REMANDS” column. If you still aren’t sure, call a Takeuchi dealer with the part number from this book – they’ll confirm fitment.
