Takeuchi TB020 Parts Catalog

You are pulling a part number off a worn Track Roller on the TB020, and the last guy ordered the wrong Front Idler because he guessed from a photocopy. That costs you a day and a trip to the supplier. Stop guessing. This is the factory Takeuchi TB020 Parts Catalog – 403 pages of exploded diagrams and OEM part numbers that match what came off the assembly line. No aftermarket interpretations, no third-party re-indexing. This is the book that the Takeuchi dealer uses to order parts for you.

Undercarriage Exploded Views (Crawler Belt, Track Roller, Front Idler)

The Undercarriage section covers every piece from the Lower Frame through the Travel Device. You get the Crawler Belt assembly with chain and shoe part numbers, Track Roller and Front Idler breakdowns, and the Track Adjuster with seal dimensions. The Dozer Blade and lower piping are separated. If your TB020 has a serial number between 1205001 and 1205750, the book lists which parts fit – no ambiguity across model year splits.

Engine & Electrical System Parts (Kubota D1105B Engine)

Inside the ENGINE FOR KUBOTA D1105B section you get the Crankcase, Oil Pan, and Cylinder sub-assemblies with gasket sizes and fastener part numbers. The Engine & Accessories 1 and 2 sections cover the alternator, starter, and cooling components. The Electrical system is split by cab and canopy variants – three cab versions broken by serial range and a separate canopy harness. That section alone can save you from ordering the wrong wire harness for a cab with a different serial number cut-off.

Hydraulic Piping, Valve Assemblies, and Pump Drive

The HYDRAULIC PIPNG & TANK chapter (yes, that typo is in the original) includes the Grease Piping, Valve & Accessories for both link and hydraulic control types, Upper Piping 1-3, the Pump Drive with bearing part numbers, and the Hydraulic Tank and Fuel Tank exploded views. The CONTROL VALVE sections have two sub-variants – link type and hydraulic type – with serial number splits at 1205719 and 1205720. If you need a Solenoid Valve, Shut-Off Valve, or Selector Valve, the part numbers are here with pattern distinctions for ISO-JCB.

Hoe Attachment and Bucket Options (Region-Specific)

The HOE ATTACHMENT chapter runs through the Hoe structure and five Bucket sections. Bucket 1 covers EC and North Europe (from 1205001) and Japan (up to 1205588). Bucket 5 is specifically for U.S.A. buckets. The Hoe piping includes two sections – main and auxiliary line – with o-ring and hose part numbers. If you are rebuilding a hoe for a TB020 that came with a factory thumb or quick coupler, cross-reference the serial number against the Bucket tables.

Source Authenticity: Factory PDF, Not a Copy

This is the original Takeuchi Parts Catalog Book No. PD3-102Z4 covering S/N 1205001-1205750. The PDF is scanned from the OEM print – you see the Japanese and English facing pages, the exploded diagrams as they appear in the dealer system. No reprint house reformatted this. The index references every part number. Compare that to aftermarket parts catalogs that renumber assemblies and leave out the Kubota engine sub-sections. I have torqued enough bolts to tell you: the difference between a factory diagram and a third-party redraw is the difference between getting the right seal and a leak.

Does This Manual Include the Kubota D1105B Engine Parts?

Yes. The dedicated ENGINE FOR KUBOTA D1105B section has its own index, plus the Crankcase, Oil Pan, and Cylinder parts lists. The main ENGINE & ACCESSORIES 1 and 2 cover the external engine components. If you need internal engine parts – pistons, rings, bearings – the Kubota section is where you find them.

How to Match Your Serial Number to the Correct Section?

Look at the first page of each section. Many assemblies have serial number splits like (1205001~1205336), (1205337~1205704), (1205705~) for the cab electrical. The manual covers S/N 1205001-1205750. Write your machine and engine serial numbers in the space on page 2 – the manual even tells you to do that. If your serial number falls between these break points, the parts list shown is correct for your machine. If your machine is outside that range, you need a different edition.
