Takeuchi TB23R, TB20R Parts Catalog

You’ve got a Takeuchi TB23R or TB20R track loader down. The part number on the hydraulic hose is worn off. You can order three different lines and hope one fits, or you can pull up a factory Parts Catalog with exploded diagrams and order the correct number the first time. That’s what this 532-page document is for. It’s not a service manual – it’s a parts identification bible. Every bolt, seal, and line is listed with its OEM part number. No guesswork.

What’s Inside a 532-Page Parts Catalog?

Eight main chapters plus a parts index. Turn to page 1 for the index and you’ll see: Undercarriage (section 1), Turntable & Control Lever (section 2), Engine & Electrical System (section 3), Hydraulic Piping & Tank (section 4), Cover & Cab (section 5), Hoe Attachment (section 6), Decal & Tool (section 7), Hydraulic Device (section 8). Each section has exploded views with callouts and a table of part numbers. For the TB23R, there’s a dedicated Engine subsection with its own contents and parts index. The TB20R is covered in the same manual with the same system.

Get the Correct Part Number from Section 3: Engine & Electrical System

Section 3 is where you’ll find the engine and electrical components. If the starter on your TB23R is dead, you need the correct OEM part number. This catalog shows the starter, alternator, wiring harness segments – all with factory numbers. Electrical system parts are cross-referenced by serial number range. For deeper engine repair procedures, check the Takeuchi TB23R Workshop Manual – Section: Vi. Engine. That’s the service manual. This one is strictly parts identification.

Undercarriage and Turntable Breakdowns

Undercarriage section covers track chains, sprockets, rollers, and idlers for both TB23R and TB20R. The Turntable & Control Lever section includes swing motors, control valves, and pedal assemblies. Each part is illustrated with a clear exploded view. You match the part number from the table to order from your dealer. Page 5 shows how to read the manual – including how to interpret compatibility codes like (L) and (R) for left and right side parts. Pay attention to serial number breaks; some parts changed after S/N 12300007.

3 Reasons to Use Factory Diagrams Over Aftermarket

First, aftermarket parts catalogs often combine multiple models into one generic drawing, leading to wrong part numbers. Second, factory diagrams show the exact assembly order – you can see how the parts stack up, which matters when ordering seals or spacers. Third, the OEM part number printed in this catalog is the number your dealer’s system expects. Cross-referencing from aftermarket catalogs introduces errors. This Parts Catalog eliminates that.

Hydraulic Piping & Tank: Identifying Leaks by Part Number

Section 4 covers all hydraulic hoses, fittings, and the tank. If you’ve got a leak at the pump outlet, the exploded view shows the O-ring and the exact hose assembly. Order the wrong O-ring and it leaks again. The catalog lists each part with its quantity per machine. For the TB20R, some pipe configurations differ from the TB23R. Use the manual’s compatibility notes to verify. When you need the workshop manual for hydraulic pressure specs, use the Takeuchi TB23R TB20R Parts Catalog – wait, that’s the same manual? Actually, for service specs you’d want the workshop manual. To avoid confusion, the Takeuchi TB23R Workshop Manual – Section: Moteur is available in multiple languages. This parts catalog is your purchasing reference. The Automotive Industry Overview won’t help here. For background on compact excavator evolution, see Automotive Industry Overview.

FAQ

Does this parts catalog include torque specifications?

No, this is a parts catalog, not a service manual. Use the workshop manual for torque values.

How do I find the part number for the swing motor on my TB23R?

Turn to Section 2: Turntable & Control Lever. Find the swing motor exploded view. The table lists the part number for the complete motor assembly as well as individual components like seals and bearings. Check the serial number range printed at the top of the page – if your machine is after S/N 12300007, you may need the later revision. Note the compatibility codes: if the part has (R) next to the number, it can replace the earlier version. If you order the wrong revision, the mounting bolt pattern might not line up. This catalog saves you that headache. Cross-reference with your dealer using the seven-digit part number.
