Takeuchi TB020 Parts Catalog – 295 Pages of Factory OEM Breakdowns

Trying to find the right part for a Takeuchi TB020 without a factory parts catalog is a waste of time and money. I’ve been turning wrenches for 28 years, and I can tell you that guessing part numbers leads to returns, delays, and broken equipment. This factory-issued Parts Catalog gives you the exact breakdown – 295 pages of OEM diagrams and part numbers so you order the right piece the first time. It’s printed from the same source the dealer uses, not some aftermarket copy that swaps in a different seal because ‘it looks close enough.’

Undercarriage and Lower Frame Breakdown

Section 1 covers the undercarriage with exploded views of the lower frame, slide shoes, bearings, and seals. Page 1 shows the lower frame assembly with reference numbers tying to part numbers like 0341000700 (cover) and 1913003850 (bearing). If you’ve ever had to order a track tensioner or sprocket seal for a TB020, you know the pain of matching dimensions. This catalog kills the guesswork because it lists the exact OEM part number, quantity, and any serial number breaks. That matters when a bolt length changes after serial 1205001 – the catalog flags it with a note.

Does the Catalog Cover Engine Parts?

Yes – Section 3 is labeled “ENGINE & ELECTRICAL SYSTEM”. That section includes the complete engine assembly, starter, alternator, and wiring harness components. Each component is shown in an exploded diagram with part numbers. For example, if you need a cylinder head gasket or a fuel injector line, you’ll find it here. But keep in mind this is a parts catalog, not a service manual. It tells you the part number, not the torque value. For that, you need the Takeuchi TB020 Workshop Manual – Section: Vi. Engine.

Electrical System: Identifying Components

The same section breaks down the electrical system – relays, fuses, connectors, and the main harness. The diagram shows routing and connector shapes. If your TB020 has an intermittent electrical fault, you can use the parts catalog to identify the exact connector part number and order a replacement pigtail instead of splicing in a generic one. That’s the difference between a repair that lasts and one that leaves you stranded.

295 Pages of Factory Diagrams – What’s Inside

Every major system is covered. Sections include: 1 Undercarriage, 2 Turntable & Control Lever, 3 Engine & Electrical System, 4 Hydraulic Piping & Tank, 5 Cover & Cab, 6 Hoe Attachment, 7 Decal & Tool, 8 Hydraulic Device, 10 Engine, and 99 Kits, Attachments and Quick Reference. Each section contains indexed exploded views with a table of item numbers, part numbers, descriptions, quantities, channel codes, and serial number applicability. Page 1 (lower frame) is a good example of how dense and usable the format is – you get a clear illustration with callouts, then a table below listing every part. No blurry scans, no cut-off numbers.

Get the Right Part Number Before You Call the Dealer

Calling a dealer with “I need a seal for the hydraulic swivel” is a gamble. They’ll ask for serial number and maybe the part number you think it is. With this catalog, you flip to page 1 or the turntable section, find the swivel joint (item 18, part number 1904006400), and give them exactly what they need. The dealer might still get it wrong if you don’t have the serial break, but the catalog lists that too. I always cross-check the “Chan.” column – if it says “L” or “R” you know it’s left or right side.

Source Authenticity – Why OEM Beats Aftermarket Every Time

This isn’t a reprint from a third-party publisher. It’s the original factory PDF released by Takeuchi. The book number is PD3-102Z4, and it covers serial range 1205001-1205750. Aftermarket parts catalogs often skip the serial break notes or merge diagrams from different years. That’s how you end up with a part that doesn’t fit and a machine down for a week. Stick with the OEM source. For a complete repair guide with torque specs and procedures, pair this catalog with the Takeuchi TB020 Workshop Manual.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. Torque values are in the workshop manual.

What if my TB020 serial number falls outside the range 1205001-1205750?

The catalog covers that exact range. If your machine is newer or older, some part numbers may differ. Check the “Serial No.” column in each diagram – it will show breaks like “1205001~” or “#~”. If your serial isn’t listed, you need the later edition or a dealer cross-reference. I’ve seen guys order a track frame only to find it’s the wrong version because they skipped the serial check. Don’t do that.

If you’re maintaining a Takeuchi TB020 and want to stop wasting time on wrong orders, this parts catalog is the reference you need. It’s the same document the dealer uses, and it puts every part number at your fingertips.
