Takeuchi TB1140 Parts Catalog – 559 Pages of OEM Factory Parts Breakdown

Let me cut straight to it. If you own a Takeuchi TB1140 compact excavator and you’re ordering parts from memory or a sketchy aftermarket website, you’re wasting time and money. I’ve seen guys order the wrong hydraulic seal three times because they didn’t have the factory part number. That’s lost billable hours and a pissed-off customer. This 559-page Takeuchi TB1140 Parts Catalog is the real deal – OEM factory documentation, not some third-party compilation. It’s the same book the dealer parts counter uses. Every part number, every quantity, every reference is straight from Takeuchi.

Engine Parts Breakdown for the Isuzu BB-4BG1-TRE

Page 1 of the index lists the Engine section as a separate chapter: “ENGINE(ISUZU BB-4BG1-TRE)”. That’s where you’ll find every component for the 4BG1-TRE diesel – injectors, pistons, gaskets, the whole rotating assembly. If you’re rebuilding or swapping parts, you need the OEM part numbers from this catalog. Aftermarket cross-references are a crap shoot. This manual gives you the exact Takeuchi and Isuzu numbers.

7 Major Sections – What’s Inside This Parts Catalog

The table of contents breaks the TB1140 into nine major sections, but I’m grouping them for clarity: Undercarriage (lower frame, tracks, rollers), Turntable & Control Lever, Engine & Electrical System, Hydraulic Piping & Tank, Cover & Cab, Hoe Attachment (boom, arm, bucket), Decal & Tool, Hydraulic Device (pumps, valves, cylinders), and the Engine chapter itself. Plus a “Kits, Attachments and Quick Reference” section at the back. That’s everything you need to order any part on the machine.

Why OEM Documentation Beats Aftermarket Parts Lists

Aftermarket parts catalogs often combine multiple models, drop superseded parts, and use generic descriptions. This manual is printed from the original Takeuchi file – the same one dealers use. The PDF bookmarks let you jump straight to Lower Frame (page 1-1 in the printed numbering) or the engine section. No guesswork, no reprints, no copy of a copy. If you want to avoid the headache of wrong parts, use the factory source.

Real-World Example: Finding a Lower Frame Seal

Look at the lower frame diagram on page 1-1. Item 2 on the callout is a SEAL with part number HIT4483676. The catalog tells you the quantity is 1, and the remark column is blank – meaning it’s a standard part, no special service notes. If you had ordered a generic seal, you’d probably get the wrong size. With this catalog, you search the number, order it, and it fits. Period.

FAQ – Four Questions About the TB1140 Parts Catalog

Does this parts catalog include torque specifications?

No. This is a parts catalog, not a service manual. For torque specs, get the Takeuchi TB1140 Workshop Manual.

How do I find the correct part number if my machine’s serial number is within the range?

The catalog is identified by Book No. BN0Z009 and covers serial numbers starting at 51400005-. Inside, each section lists the applicable serial number range. For example, the lower frame section is marked “S/N 51400005-”. If your machine is within that range, every part listed is correct. If your serial number is outside, you may need a different revision. The index page (page 0) shows the reference model “MACHINERY(TB1140-A4)” – double-check your machine’s model code against that. Also, the “Chan.” column indicates any field changes. If you see a blank, it’s the original part. If there’s a letter, it means a supersession. Always verify with the dealer if you’re unsure, but this catalog is the starting point.

Is this manual in English?

Yes, original factory English from Takeuchi.

Can I print pages from the PDF?

Yes. The PDF is not locked – you can print any page or section you need for the workbench. The bookmarks make navigation fast.
