Takeuchi TL140 Parts Catalog – What You Actually Need on the Bench

If you have ever ordered a track roller for a TL140 and ended up with the wrong seal package because some third-party website listed a superseded part without telling you, you know exactly why this catalog exists. I have had guys in my shop waste half a day waiting on a part that did not fit because they trusted an aftermarket lookup table. That stops here. The Takeuchi TL140 Parts Catalog is the factory-issued book, Book No. BT9Z009-2, covering serial numbers 21400011 and up. 410 pages of exploded diagrams, OEM part numbers, and serial number breaks that tell you exactly when a part changed. No reprints, no scanned blurry copies – this is the original factory document.

UNDERCARRIAGE: Track Roller Assembly Breakdown

Section 1 opens with the undercarriage, starting with the track roller assembly on page 1-1. Takeuchi lists every component from the roller sub-assembly (part X08811-30400-2) down to the snap ring and O-ring. You get the bushing, the floating seal, the plug, bolt, and washer quantities for each position. If you need to rebuild a track roller, you pull this page and order the exact seal kit without calling the dealer twice. The catalog uses a reference index system (Ref T9A040) to cross-link assemblies, so you can find a part number fast.

ENGINE & ELECTRICAL SYSTEM: ISUZU 4JG1-TPA Coverage

Section 3 covers the Engine and Electrical System, and Section 10 dives specifically into the ISUZU 4JG1-TPA engine. If you have a TL140 that needs a starter, alternator, or any engine-side component, this is where you find the part number separated by serial number. Page 0-1 (the index) confirms the serial break at 21400011. The catalog notes changes with a “Chan.” column – you will see supersessions and rev dates like 2007.04.18. Do not order a part for a machine built before that date without checking the serial number column.

HYDRAULIC PIPING & TANK: What the TOC Shows

Section 4 covers hydraulic piping and the tank – lines, fittings, seals. This is where a wrong O-ring can cost you a hydraulic pump. The catalog gives you the part numbers for each hose assembly and the torque for fittings (referenced in the service manual, not this parts book – you want that too). If you are piecing together a hydraulic leak repair, you need the exact part from this catalog. Aftermarket parts books often combine hose lengths that are not the same. The OEM catalog does not. Related manual: Takeuchi TL140 Workshop Manual for the hydraulic torque specs.

7 Major Sections – Not Just Parts Lists

The TOC breaks into seven main groups plus an engine-specific section and a kits/attachments section:

• UNDERCARRIAGE
• MAIN FRAME & CONTROL LEVER
• ENGINE & ELECTRICAL SYSTEM
• HYDRAULIC PIPING & TANK
• COVER & CAB
• ATTACHMENT
• DECAL & TOOL
• HYDRAULIC DEVICE
• ENGINE (ISUZU 4JG1-TPA)
• Kits, Attachments and Quick Reference (section 99)

Each section uses exploded diagrams with callouts that match the parts table. Part numbers are Takeuchi OEM, not reboxed generic numbers. If you are using this catalog, you are ordering from the same parts book a dealer tech pulls up.

Source Authenticity – Factory Print vs. Aftermarket Copy

I do not trust aftermarket documentation. I have seen a third-party “parts catalog” list a torque converter seal that did not exist for a TL140 because they copied from a different model. This PDF is a direct scan of the original factory document (Book No. BT9Z009-2) with the Takeuchi logo, serial number break, and revision date. No watermarks from some reseller. The [Takeuchi TL120 TL130 TL140 TL150 User Manual – OEM Factory Specs] is another factory document that works with this catalog – they cross-reference. For a smaller machine like the TL26, check the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual.

Who Should Use This – and How

If you own a TL140 and do your own repairs, you need this catalog to order parts without guesswork. If you run a shop, put this on the workbench next to the service manual. When a boom cylinder seal blows, you look up the seal kit part number, check the serial number column, and order. That is it. You do not waste time on hold with a dealer. For electrical diagnostics, the section 3 wiring diagrams (part of the electrical system listing) show connector part numbers and harness splits. You can order a pigtail connector before you even pull the old one out. Keep the [Automotive Industry Overview] background knowledge in mind – proper part tracking prevents safety issues from wrong components.

Does this catalog include torque specs for bolts?

No. This is a parts catalog, not a service manual. Torque specifications are in the separate workshop manual. The parts catalog gives you the bolt part number and quantity so you order the right fastener for the job.

What serial number range does this cover?

Serial numbers 21400011 and up. The cover page shows S/N 21400011- and the index references that break. If your machine has a serial number below that, you need an earlier catalog.

Are the part numbers still current?

The catalog includes a revision date of 2007.04.18. Some parts may have been superseded after that date. However, the Takeuchi part numbers listed are the original OEM numbers. Use them to cross-reference with a dealer if needed. The catalog is the starting point – you still verify availability, but at least you have the correct base number.

How are the exploded diagrams organized?

Each section starts with an index page (e.g., Page 0-1 for the general index). Then each assembly page (like page 1-1 for track roller) shows a drawing with callout balloons and a corresponding parts table with item number, part number, description, quantity, and a remarks column for serial number breaks or revision notes. It is the same layout the dealer uses.

Stop chasing parts with aftermarket cross-reference lists that show five different numbers for the same seal. Get the factory document that Takeuchi put together. 410 pages. OEM part numbers. Serial number breaks. If you have a TL140 that needs parts – undercarriage, engine, electrical, hydraulics, cab – this catalog prints exactly what you need.
