Takeuchi TL140 Parts Catalog

If you’ve ever ordered a part for a TL140 and got the wrong one because you guessed at the part number, you already know why this book matters. The Takeuchi TL140 Parts Catalog (Book No. BT9Z005) is 457 pages of exploded diagrams, part numbers, and compatibility notes. Every bolt, bush, and plate is listed by number. No more calling the dealer with “the thing under the cab.” You get the exact part number, description, and quantity per machine.

Page 1 shows the index. Take the time to understand the reference system before you start flipping. The first five pages explain how to read the manual, including the serial number range (S/N 21400011-). If your machine falls outside that range, this catalog might not apply. Verify that before you order.

Engine & Electrical System: Full Parts Breakdown

Section 3 covers the Engine and Electrical System completely. You get the intake, exhaust, cooling, starter, alternator, and all wiring harness components listed as separate items. Each part has a number, a description, and a note about which revision it replaces. If you see an “X” before the part number, that means the part is not sold individually — it’s part of an assembly. Don’t waste time asking for it.

For the electrical side, the catalog includes the battery, fuses, relays, and the control lever assemblies. The travel lever and swing pedal section (pages 3–5) shows the plate, bush, and bolt breakdown. Page 3 explains how to interpret the compatibility letters: (P) for inside, (L) for left, and how to substitute parts when the revision changes. Read that page before you order anything.

457 Pages: What’s Inside Each Section

The catalog is split into eight indexed sections plus a separate engine index:

• 1 – Undercarriage (tracks, rollers, sprockets)
• 2 – Main Frame & Control Lever
• 3 – Engine & Electrical System
• 4 – Hydraulic Piping & Tank
• 5 – Cover & Cab
• 6 – Attachment
• 7 – Decal & Tool
• 8 – Hydraulic Device
• Parts Index (alphabetical/numerical cross-reference)
• Engine for TL140 – separate contents and parts index

That’s everything from the decal kit to the final drive. If you need a specific bolt from the travel lever, you look up section 2, find the exploded view, and cross-reference the part number. The index at the back lists every part number alphabetically and numerically. Useful when you have a number but don’t know where it goes.

Order Parts Correctly the First Time

The manual includes a full “How to Order Parts” guide (page 5). You need: machine model, serial number, part number, item number on the diagram, description, and quantity. Miss any one of those and the dealer will kick the order back. The catalog also marks superseded parts with asterisks and “★” symbols. Those denote that the older part has been replaced by a newer assembly. Order the wrong revision and it won’t fit. This catalog tells you exactly which revision applies to your serial number.

Compatibility notes are printed right next to each part. Example: (L) means the part can be used on the left side; (P) means inside. If you see a small letter like ‘a’ or ‘b’ next to the part, those are interchangeable within the same letter group. Page 3 has the complete legend. Skim it, don’t skip it.

7 Systems Covered in This Catalog

The catalog breaks the Takeuchi TL140 into seven major systems (if you count the separate engine section as one). Each system gets its own color-coded index tab in the PDF. You can jump straight to undercarriage or hydraulic piping without scrolling through the whole file. For a home-garage mechanic rebuilding a TL140 undercarriage, this is the single source of truth for track chain parts, sprocket seals, and roller flanges. No aftermarket substitutes, no generic measurements – only the factory numbers.

Period.

Source Validity: OEM vs. Aftermarket

This is a direct scan of the Takeuchi factory catalog – not a third-party reprint. The Japanese, English, French, and German text is original. The part numbers match Takeuchi’s own system. I’ve seen too many aftermarket catalogs that flip the part number digits or miss a revision level. That mistake costs you a week of downtime waiting for the correct part. This catalog eliminates that risk. If you’re serious about keeping a TL140 running, you don’t guess. You use the factory index.

Frequently Asked Questions

Does this catalog include the engine?

Yes. Section 3 covers the engine and electrical system completely.

How do I verify a part number from this catalog?

Start by finding the exploded view for your machine’s serial number (S/N 21400011-). Each numbered item corresponds to a part number in the adjacent table. Cross-reference that part number against the Parts Index at the back to confirm it’s listed for your system. Check the compatibility notes (P, L, asterisks) on page 3–5. If the part has an “X” before the number, it is not sold separately — order the parent assembly. Always provide the machine model, serial, part number, item number, description, and quantity to the dealer. The catalog’s compatibility section explains how revisions interchange. For example, a part marked (L) can replace the same part on the left side. If you still have doubt, call Takeuchi with the book number BT9Z005 and your serial range. They will confirm.
