Takeuchi TB145 Parts Catalog – Factory OEM Parts Breakdown

I’ve seen guys order a water pump for a TB145, get it in, then find out it doesn’t fit because they ignored the serial number break. That’s why a factory parts catalog exists. This Takeuchi TB145 Parts Catalog runs 729 pages of OEM part numbers, exploded diagrams, and serial number ranges. You don’t guess. You look up the part, verify the serial number range, and order it. Period. The index on page 0 lists every section from undercarriage to the hydraulic device – each keyed to a specific serial number start.

Takeuchi TB145 Parts Catalog – Construction and Layout

Page 0 shows the full index. Nine major groups: undercarriage, turntable & control lever, engine & electrical system, hydraulic piping & tank, cover & cab, hoe attachment, decal & tool, hydraulic device, and a separate engine section for the 4TNE88 and 4TNV88 variants. Every group has its own reference number. You flip to that page, see the diagram, and read the part number table. No flipping through generic sections – each part is pinned to the serial number range it fits. The crawler belt section, for example, occupies pages 1-2 and lists steel belts in 380, 400, and 460mm widths with old and new type indicators, plus rubber belt options that vary by serial number block from 14510004 up to 14516942 and beyond.

Engine Breakdown – 4TNE88 and 4TNV88 Variants

The Engine section isn’t one-size-fits-all. Three separate engine groups: 4TNE88-(E)TB(1)(Z) for S/N 14510004-14513260, 4TNE88-ETBZ for S/N 14513261 and up, and 4TNV88-QTB (cab) / QTB1 (canopy) also from S/N 14513261. Each has its own part numbers for cylinder head, pistons, gaskets, injectors – everything. If you try to use a 4TNE88 part on a 4TNV88, it won’t bolt up. The catalog tells you exactly which engine code matches your machine’s serial number.

Undercarriage and Crawler Belt Parts – Page 1-2 Details

Page 1-2 drills into the crawler belt assembly. Steel belts: old type 380mm uses link part number 1914039001 (R.H.) and 1914039002 (L.H.) with 37 links per side. New type 400 and 460mm belts use different link and shoe plates. You also get the master link pins, bushings, track pins, bolts, and nuts – all with quantities. Rubber belt options list five different part numbers depending on serial number range and whether the machine has a higher (H) or lower (L) ground clearance. This level of detail means you don’t end up with a belt that’s 20mm too narrow or a master link that doesn’t fit.

Serial Number Ranges – Why They Matter

The entire catalog hinges on serial number breaks. Take the 4TNE88 engine: if your machine is S/N 14510004-14513260, you use one set of parts. If it’s 14513261 or later, you switch to a different group. Same for the undercarriage – rubber belt part numbers change at specific six-digit thresholds. Understanding serial number ranges is critical, as in the Automotive Industry Overview. Your machine’s serial plate is the key. The Automotive Industry Overview also emphasizes the importance of correct part identification. Ignore the range and you’ll be ordering wrong parts every time.

Compare OEM vs Aftermarket Parts Catalogs

Aftermarket parts catalogs often cross-reference a generic part number that might work – or might not. They don’t show the serial number splits, the old-type vs new-type notes, or the exact hardware thread and length. An OEM catalog like this one prints the actual Takeuchi part numbers and the factory diagrams. That means you can hand the part number to your dealer and get the right piece the first time. No returns, no “close enough” fits that wear out in 50 hours. For the full service procedures, pair this with the Takeuchi TB145 TB150 Technical Manual. For complete workshop instructions including torque specs and removal sequences, get the Takeuchi TB125 TB135 TB145 Workshop Manual. And if you need another copy of the parts catalog itself, the Takeuchi TB145 Parts Catalog is right here.

Does this catalog include torque specs?

No. This is a parts catalog, not a service manual. Torque values are in the workshop manual.

How do I find the right part for my serial number?

Look at the serial number on your machine’s identification plate. Each section in this catalog is broken down by serial number range, for example engine sections for 4TNE88-(E)TB(1)(Z) covering S/N 14510004-14513260. Find your engine type and serial number range, then use the index on page 0 to locate the correct exploded diagram. Cross-reference the part number and order it.

Can I use this for a TB145 with a different engine?

If your TB145 has the 4TNE88 or 4TNV88 engine, yes. The catalog covers those three variants. Check the engine section heading for your specific engine code.

Is this a reprint or scanned copy?

Original OEM factory scan, not a reprint. Clean diagrams and legible numbers.
