Takeuchi TB070 Parts Catalog – OEM Factory Parts Breakdown

I’ve been turning wrenches for 28 years, and I’ve seen more than a few jobs get held up because somebody ordered the wrong part. They grabbed a number off an aftermarket parts list, the seal was the wrong diameter, the hydraulic fitting didn’t match, and then the machine sits for two days while you wait for the right piece. That’s what happens when you don’t have the Takeuchi TB070 Parts Catalog in your shop. This is the actual factory book – Book No. PL1-101Z5-1 – covering serial numbers 1703004 through 1705487. It’s 414 pages of exploded-view diagrams, part numbers, quantity counts, and compatibility codes that tell you exactly which parts interchange. No guesswork, no cross-referencing a third-party database that’s two revisions behind.

Understanding the Parts Catalog Layout

Takeuchi didn’t design this thing to be confusing. The first few pages (pages 2 through 5) explain how to read the manual. They show you the reference index, how to interpret part numbers, what the asterisk symbols mean for assemblies, and most importantly – the compatibility symbols. You’ll see (O) for full interchangeability, (+) for limited interchange within the same mark, and (L.) for lowercase-letter compatibility. If you’ve ever ordered a part that didn’t fit because the machine had a mid-production change, those symbols are what save you. The manual also includes a note about machine serial number ranges – if your TB070 falls outside 1703004-1705487, you need a different edition. This catalog is serial-number-specific, and that’s the only way to guarantee you’re ordering the correct piece.

414 Pages of Verified Part Numbers

Every page in this catalog is a direct scan from Takeuchi’s own parts documentation. There are 414 pages packed with exploded diagrams for the undercarriage, boom, arm, bucket, hydraulic system, travel lever and swing pedal (TB101000-110000 section), engine, radiator, and electrical components. Each part number is listed alongside the quantity required per machine. For assemblies, you’ll see a double asterisk (**) indicating sub-components. The manual also includes a “NOTES” column for special instructions like “AR” – as required – for parts that vary by machine configuration. This is not a condensed aftermarket list; it’s the full factory catalog.

Does This Catalog Cover Your Serial Number Range?

Takeuchi TB070 serial numbers are stamped on the machine frame near the operator’s seat. This particular edition – Book No. PL1-101Z5-1 – covers S/N 1703004-1705487. If your machine falls outside that range, the parts diagrams may be different. The catalog explicitly lists the applicable serial range on the title page and in the reference index. I’ve seen guys buy a generic parts CD and then wonder why the track tensioner doesn’t match. Don’t be that guy. Check your serial number against the range before you order. If you need a different serial range, look for the corresponding edition – but for the 1703004-1705487 population, this is the exact document you need.

Get the Right Part the First Time: Using the Compatibility Symbols

Look at the bottom of any parts diagram page. You’ll see a column labeled “Compatibility” with symbols like (O), (+), (日), (L.). These aren’t random; they’re keyed to the machine’s production changes. For example, if a part number has an (O) symbol, it can replace any earlier version of that part. A (+) symbol means it can only replace parts with the same mark letter. If you ignore those symbols, you might order a hydraulic cylinder seal that doesn’t fit a later-series machine. The manual explains all of this on page 4 of the “How to Read the Parts Manual” section. Take the time to read those four pages – it’s faster than returning a wrong part and waiting another week.

Parts Catalog vs. Workshop Manual: What’s the Difference?

This is a parts catalog, not a repair manual. It tells you what parts go where, the part numbers, and how many you need. It does not include torque specifications, disassembly procedures, or troubleshooting flowcharts. For that, you’ll want the Takeuchi TB070 2000 Workshop Manual – Factory Specs for Compact Excavator. That manual covers the engine rebuild, hydraulic system pressures, and electrical diagnostics. But if you’re rebuilding a final drive and you need to know which bearing race goes in first, start with the parts catalog to identify the correct bearing, then move to the workshop manual for the installation procedure. The two documents work together. I also keep a Takeuchi TB070 2000 Workshop Manual – Factory Specs for Compact Excavator on the shelf next to this catalog for any job that involves full teardown. For a complete parts breakdown, you already have the Takeuchi TB070 Parts Catalog – OEM Factory Parts Breakdown in your hands.

Takeuchi is a reputable manufacturer, as recognized in the Automotive Industry Overview – though this is construction equipment, the same supply-chain standards apply. If you want to understand the broader context of OEM documentation, the Automotive Industry Overview page on Wikipedia gives background on why factory specs are critical.

Frequently Asked Questions

Can I use this catalog to order parts for any TB070?

Only if your machine’s serial number falls within the range 1703004-1705487. Earlier or later machines may have different part numbers.

What do the symbols like (O) and (+) mean in the diagrams?

These are compatibility codes. (O) means the part is fully interchangeable with all earlier versions. (+) means it can only replace parts with the same mark letter. The manual explains all symbols on page 4 of the “How to Read” section. Ignoring them is a common source of ordering errors.

Is this a PDF format or a printed book?

It’s a digital PDF format. You can print specific pages for the shop floor or keep it on your tablet. The 414 pages are scanned at high resolution, so exploded views are clear.

How do I know which part number to order if my machine has been modified?

If the previous owner replaced parts with non-OEM components, the catalog won’t help. You’ll need to identify the original part by cross-referencing the machine serial number and consulting the compatibility notes. In some cases, you may need to contact Takeuchi dealer support with the serial number. The catalog gives you the factory baseline – modifications are outside its scope.

I’ve been using Takeuchi parts catalogs for years, and this one is the genuine article. 414 pages, factory part numbers, compatibility symbols, and serial-number-specific coverage. If you’re working on a TB070 in the 1703004-1705487 range, this is the only parts document you should trust. Stop wasting time on aftermarket lists that leave out critical details. Access the Factory Manual now and get the right part the first time.
