Takeuchi TB135 Parts Catalog – 653 Pages of Factory-OEM Part Numbers

If you’ve ever ordered the wrong part number for a Takeuchi TB135 Parts Catalog and ended up with a hydraulic line that doesn’t fit or an undercarriage bolt that’s half an inch off, you already know why this 653‑page book exists. Aftermarket catalogs guess. OEM factory data doesn’t. This is the exact same document Takeuchi dealers use when you walk in and say “I need a replacement for serial number 13510004‑.”

The catalog breaks down every subsystem into nine chapters: Undercarriage, Turntable & Control Lever, Engine & Electrical System, Hydraulic Piping & Tank, Cover & Cab, Hoe Attachment, Decal & Tool, Hydraulic Device, and a Numerical Index. Each chapter spits out the factory part number, quantity, and supersession notes. No third‑party reprints. No fuzzy scans of a scanned scan. You get the original Japanese‑English‑French‑German layout that tells you exactly which version of a seal fits which serial break.

Engine & Electrical System: Two Engine Families Covered

Chapter 3 covers the Engine and Electrical system separately for the two engine families used in TB135 production. The 3TNE88‑TB, TB1, ETB, ETB1 group has its own parts index. The 3TNV88‑QTB, QTB1, QTB2 group has a separate index. If you’re swapping an injector or a starter on a machine that’s seen twenty years of San Antonio heat, you need the right index. The manual doesn’t lump them together.

Electrical components—alternators, wiring harness sections, glow plugs—are listed with the exact Takeuchi part number. That’s critical when you’re trying to avoid a three‑week wait for the wrong rectifier. The section also includes the hydraulic devices chapter (Chapter 8) for pumps, valves, and solenoids, so you can trace a no‑start issue back to a failed pressure switch and order the correct unit the first time.

Undercarriage and Hoe Attachment – Where Wear Parts Hide

Chapter 1 (Undercarriage) gives you track rollers, sprockets, idlers, and endless tracks with serial‑break indications. If your TB135 has a frame that’s been welded or stretched, you’ll see the compatible ranges. Chapter 6 (Hoe Attachment) breaks the stick, boom, bucket linkage, and pins into individual part numbers. Dealers charge markup on these items. Ordering from the OEM catalog means you can source the exact roller assembly yourself and skip the 40% middleman.

Every illustration in the catalog includes a reference number and a parts table directly underneath. The “How to read the parts manual” section (pages 1‑4) walks you through the symbols: (L) for left, (R) for right, (AR) for optional, and compatibility notes like (U) for upward compatibility. If you’ve never used a Japanese OEM parts book, read those four pages first. They’ll save you from buying a left‑hand travel lever when you need a right.

Does This Catalog Replace the Workshop Manual?

No. This is a parts catalog. It doesn’t tell you how to torque the turntable bearing or how to bleed the hydraulic circuit. For those procedures you need the Takeuchi TB125 TB135 TB145 Workshop Manual or a dedicated service manual. What this catalog does is give you the exact screw size, the exact gasket thickness, and the correct supersession path so that when you open the service manual and it says “replace part X,” you know which part X to pull off the shelf.

3 Reasons OEM Documentation Trumps Aftermarket

1. Aftermarket catalogs often merge serial‑break ranges. Takeuchi splits them by three‑digit serial prefixes. The OEM catalog shows the exact start point (S/N 13510004‑) so you don’t order a part that fits an earlier production run.
2. Illustration quality. The OEM scans are clean, the callout numbers are legible, and the parts table aligns with the picture. Aftermarket compilations frequently rotate or crop images, making it impossible to verify which washer is which.
3. Numerical index (Chapter 9). Aftermarket PDFs rarely include a full numerical index. This one does, so if you have a part number from an existing machine and need to know what it belongs to, you can look it up in seconds instead of flipping through nine chapters.

Dealers don’t use aftermarket. They use the Takeuchi Book No. BG4Z006. That’s what you’re getting here—a direct digital file, no watermarks, no garbage. It’s the same file that Automotive Industry Overview references when discussing OEM supply chains, minus any third‑party alterations.

Who Should Buy This Catalog?

If you own a TB135, you need this. Home‑garage guys who plan to keep their mini‑ex for another ten years will save multiples of the purchase price on the first undercarriage overhaul. Independent mechanics who take in excavator work from local farmers or rental yards need this to give accurate quotes without calling the dealership every time. Even beginners can use it—the “How to read” pages are written in plain language, and the exploded drawings show exactly where each bolt goes.

For the TL26 owners, there’s also the Takeuchi TL26 Parts Catalog – 288 Page OEM Factory Manual which follows the same format but for the tracked loader. And if you want a second TB135 catalog for a different serial range, the Takeuchi TB135 Parts Catalog product page has details on that variant.

The Automotive Industry Overview notes that OEM data integrity reduces warranty claims. Same principle applies here: one wrong part can cost a full day of downtime. This catalog is the insurance against that.

FAQ

Can I find torque specifications in this parts catalog?

No. Torque values are not listed in a parts catalog. You need the factory service manual for assembly torque.

Does the catalog include exploded diagrams for the hydraulic pump and control valves?

Yes, Chapter 8 (Hydraulic Device) covers the pump, control valve, and related components with full exploded views and part numbers. It does not include internal seal kits or repair procedures, but it does list the individual cartridge valves, O‑rings, and springs that make up those assemblies. If you are rebuilding a piston pump, you will need the service manual for clearances and torque, but the parts catalog tells you exactly which revision of the swash plate is fitted to your serial number.

Access the Factory Manual and keep it on your tablet or laptop in the shop. The next time you’re elbow‑deep in a TB135 track frame and you need a roller part number, you’ll have the answer in thirty seconds, not thirty minutes on hold with a parts counter.
