Takeuchi TB135 Parts Catalog

If you’re ordering parts for a TB135 from a generic aftermarket list, you’re going to get the wrong part. I’ve seen it happen. A guy brings in a hydraulic pump seal that doesn’t match the port face because the online seller listed a “universal” number. That costs you time, cash, and a customer pissed off that his mini-ex is down another day. This Takeuchi TB135 Parts Catalog is the factory-issued book – 628 pages, OEM part numbers, exploded diagrams, and cross‑references for both the 3TNE88 and 3TNV88 engine families. If you turn wrenches on compact excavators, this is how you order correctly the first time.

Engine & Electrical System: What You Get

Section 3 covers the ENGINE & ELECTRICAL SYSTEM. Inside that chapter you’ll find the breakdown for two separate engine lines: 3TNE88-(E)TB(1) and 3TNV88-QTB, QTB1, QTB2. Each engine section has its own contents and parts index. The electrical side includes starter, alternator, wiring harness details – with factory part numbers you can hand to any dealer counter. No guessing which relay fits which year. The manual also lists the serial number break point (S/N 13510004-) so you know exactly which revision your machine matches.

Undercarriage Parts Breakdown

Chapter 1 – UNDERCARRIAGE – gives you the track frame, sprocket, idler, roller, and track shoe assemblies. Each illustrated page has a figure number and a table with the part number, description, quantity, and compatibility notes. See the “AR” notation for optional parts. Page 4 of the manual explains the symbology: (W) for retrofitted part numbers, (Y) for superseded numbers, (R)/(L) for right and left. If you need a final drive seal or a track adjuster assembly, you look here first.

Hydraulic Piping & Tank – Real Names, Real Numbers

Chapter 4 – HYDRAULIC PIPNG & TANK (yes, they spelled it PIPNG in the original – that’s the factory file) – covers all hoses, tubes, fittings, and the hydraulic oil reservoir. The parts are grouped by functional circuit. The manual clearly shows which o‑ring goes where and gives the actual Takeuchi part number. Aftermarket cross‑reference sites often swap metric and SAE thread sizes; this catalog uses only factory dimensions. You order by the number printed on the page, not what some forum guy guessed.

Why This Parts Catalog Beats Aftermarket Lists

I’ve dealt with third‑party parts catalogs that reprint blurry screenshots from a 2003 PDF. They leave out the supersession notes and compatibility flags. This OEM catalog includes the “How to read the parts manual” section (pages 2–5 of the PDF) that explains every symbol: the (*) for parts with restricted availability, the (AR) for as‑required items, and the compatibility letters. Aftermarket sources don’t give you that. You also get the full parts index at the back – 628 pages of organized data. You want a part number for a hoe attachment bushing? Chapter 6 – HOE ATTACHMENT. Need a decal or safety sticker? Chapter 7 – DECAL & TOOL. It’s all there.

Does This Manual Cover Both 3TNE88 and 3TNV88 Engines?

Yes. The Engine section lists two sub‑assemblies: 3TNE88-(E)TB(1) and 3TNV88-QTB, QTB1, QTB2. Each engine type has its own table of contents and separate parts index. If your TB135 was built before a certain serial number or after, the manual tells you which parts apply. The electrical system diagrams are also split by engine variant. Always check the serial number on your machine (stamped on the turntable frame) before ordering – the manual references S/N 13510004- as the starting point for this book number BG4Z004.

Can I use this parts catalog to rebuild the engine?

No. This is a parts catalog, not a service manual. It gives you part numbers and diagrams, not torque specs or assembly steps. For repair procedures you need a workshop manual like the Takeuchi TB125 TB135 TB145 Workshop Manual.

How do I find the correct part number if my machine has a serial number below 13510004?

This book number BG4Z004 covers serial 13510004 and above. If your machine is older, you need the earlier edition parts catalog. The manual’s introduction clearly states the serial break. Always verify your machine’s serial number against the cover page before ordering. The parts index at the back lists every component by name and number; cross‑reference with the exploded illustration to confirm fitment. If you still have doubt, call a Takeuchi dealer with the serial and the part description – they can pull the superseded number from their own system.

Does the manual include wiring diagrams?

Yes, within the ENGINE & ELECTRICAL SYSTEM chapter there are wiring harness illustrations and connector part numbers. It’s not a full electrical troubleshooting guide, but it shows the routing and connector IDs so you can order the correct harness section.

What is the difference between this parts catalog and the Takeuchi TB135 Parts Catalog listed on another site?

There is only one official TB135 parts catalog from Takeuchi – 628 pages, OEM, book number BG4Z004. Any site claiming a different version is either a reprint of the same file or a third‑party compilation. Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual is for a different machine. Stick with factory‑sourced documents to avoid mismatched part numbers.

Look over the table of contents and compare it to any aftermarket list you’ve used. The eight main chapters cover every system: undercarriage, turntable, engine/electrical, hydraulics, covers/cab, hoe attachment, decals, and hydraulic devices. Each part number ties directly to Takeuchi’s inventory. For the Automotive Industry Overview you’ll see why OEM documentation matters – the same principle applies to construction equipment: factory specs eliminate ambiguity. Automotive Industry Overview references the broader context of standardization. If you’re tired of ordering wrong parts, get the factory file. Access the Factory Manual now.
