Takeuchi TB145 Parts Catalog – Factory OEM Manual

If you’ve ever ordered a part for a Takeuchi TB145 and got the wrong one because you relied on a aftermarket cross-reference, you know the pain. I’ve been wrenching for 28 years, and I’ve seen more stripped threads and returned parts than I care to count. That’s why this Takeuchi TB145 Parts Catalog – the real factory book – matters. It’s 701 pages of exploded diagrams, genuine part numbers, and assembly breakdowns. No translation errors, no “compatible with” nonsense. This is what the dealer uses, and now you can have it on your tablet or printed out on the bench. Serial numbers from 14510004 onward. Book No. BK37006.

What’s Inside: 8 Major Sections and Full Parts Index

The table of contents splits the machine into logical assemblies. Section 1 is the undercarriage – track frames, rollers, sprockets. Section 2 covers the turntable and control levers (including travel lever and swing pedal). Section 3 is where you’ll find the engine and electrical system – and trust me, if you’re chasing a failed starter or a bad alternator, you need the exact part number. Section 4 goes through the hydraulic piping and tank. Section 5 is the cover and cab. Section 6 handles the hoe attachment. Section 7 lists decals and special tools. Section 8 is the hydraulic device section – pumps, valves, cylinders. Then there’s a full parts index at the back. That’s how a factory manual should be laid out – no fluff, just data.

Engine Section: 4TNE88 E TB and 4TNV88 Q TB

The catalog includes two separate engine subsections: the 4TNE88 E TB and the 4TNV88 Q TB. Each has its own contents and parts index. Why does that matter? Because the injection pump, glow plugs, and even the head gasket differ between these two. The manual shows the exact part number, the illustration, and the change level. If you’re rebuilding one of these engines, you need the correct piston ring set and liner. Get it wrong and you’re doing the job twice. The page count for the whole document is 701, but the engine section alone runs dozens of pages. Takeuchi TB145 TB150 Technical Manual goes deeper into service procedures, but this parts catalog is the one you want for ordering.

7 Systems Covered – One Part Number per Location

Every component in the TB145 is assigned a unique part number. The manual shows the exploded view (illustration number), the part number, the part name, quantity, and serial number applicability. On page 5 of the manual (the “How to Read the Parts Manual” section) they explain the compatibility codes: (L) and (R) indicate left or right, and asterisks mark corrected parts. If you see an asterisk next to a part name, that means the factory revised it. You want the revised version, not the old one. This catalog tells you that. Don’t rely on a generic aftermarket PDF that might list the old part number. The factory book gives you the current revision. Takeuchi TB125 TB135 TB145 Workshop Manual covers the actual repair steps, but for ordering, this parts catalog is your one-stop.

Does This Manual Cover the Electrical System?

Yes. Section 3 is labeled “ENGINE & ELECTRICAL SYSTEM”. Inside you’ll find the starter motor, alternator, wiring harnesses, switches, and the control unit. The parts index lists every connector and relay. If you’re tracking down a no-start condition and you suspect a bad relay, the catalog gives you the part number so you can order it from the dealer or a genuine parts supplier. No guessing. No calling the dealer with a vague description. You get the number, you order it, you install it. The Automotive Industry Overview might tell you how modern machines are built, but this manual tells you exactly what’s inside your TB145.

3 Reasons to Use the Factory Parts Catalog Instead of Aftermarket

First, accuracy. Aftermarket catalogs often use generic illustrations or list superseded parts without notice. Second, serial number tracking. This manual is keyed to S/N 14510004–, meaning it’s model-specific. Third, the parts index uses the same numbering system as the dealer’s computer. When you call the parts counter, you can give them the exact 10-digit number from this book. No back-and-forth. I’ve seen too many guys order “the same part off Amazon” and end up with a different bolt pattern. Save yourself the return shipping. Access the factory manual now.

FAQ

Can I use this manual to find the part number for the hydraulic pump?

Yes. Open section 8 (HYDRAULIC DEVICE). The exploded view shows the pump assembly and lists the part number for the main pump, the seal kit, and all internal components. If your machine serial falls within the range, it’s listed.

What if I need a wiring diagram for the electrical system?

This parts catalog does not include wiring diagrams or testing procedures. It shows the physical parts (connectors, relays, harnesses) with part numbers. For diagnostic steps, you would need the workshop manual. Takeuchi TB145 Parts Catalog is for parts, not repair steps.

This is the real deal. OEM Takeuchi documentation, printed from the original PDF (701 pages, Book No. BK37006). No reprints, no third-party scans. If you’re working on a TB145, you need this on your bench. Automotive Industry Overview is interesting, but this manual is essential. Access the factory manual and stop guessing.
