Takeuchi TB145 Parts Catalog

You have a Takeuchi TB145 on the lift, or sitting in the yard with a blown track or a hydraulic leak you can’t trace. The parts supplier wants a part number — you want to be sure it’s the right one before you spend money on something that won’t fit. That’s exactly why this Takeuchi TB145 Parts Catalog exists. 729 pages of factory-issued part numbers, illustrations, and serial number breaks. No aftermarket guessing. No reprints. This is the same binder the dealer’s parts counter uses.

Engine Breakdowns: 4TNE88 and 4TNV88 Variants

Three separate engine sections inside this catalog cover every TB145 produced up to the last serial number. You get the Engine for 4TNE88-(E)TB(1)(Z) from serial 14510004 to 14513260, the 4TNE88-ETBZ starting at 14513261, and the 4TNV88-QTB (cab) / QTB1 (canopy) also from 14513261 on. Each engine listing includes a complete parts breakdown — cylinder block, head, fuel system, cooling, electrical. Page 2 of the index shows you exactly where to find those sections. If you are swapping a long block or just need a thermostat gasket, you go straight to the right page.

Crawler Belt Assembly: Steel vs Rubber Options

The TB145 runs on either steel or rubber crawler belts, and the catalog lays out every component separately. For steel belts you get part numbers for left and right links, master links, bushings, track pins, bolts, and shoe plates with width options (380mm, 400mm, 460mm). The rubber belt section covers six different serial number breaks — 1914065200, 1914065400, 1914065500, 1914065610 — each tied to a specific serial range. You need a belt for a machine built between 14512399 and 14512798? That’s number 1914065400. No cross-referencing, no calling a hotline. It’s printed on the page.

Index Structure: How to Find Your Part Number

The catalog uses a simple index layout. Page 1 lists major sections: Undercarriage, Turntable & Control Lever, Engine & Electrical System, Hydraulic Piping & Tank, Cover & Cab, Hoe Attachment, Decal & Tool, Hydraulic Device, and Engine. Each section has a reference number. The “Engine” section is broken into the three engine variants as described above. When you turn to the section, you get a table with columns: Item number, Part number, Description, Quantity, Channel, Serial number range, Service, and Remarks. The drawings show exploded views with callouts. This is not a repair manual — it’s a parts ID tool. You use it to order the exact fastener, seal, or hose, not to learn how to rebuild the pump.

Serial Number Ranges: Why They Matter

Every part in this Parts Catalog is tied to a machine serial number. The cover page says “TB145 Book No. BK3Z010 S/N 14510004-“. That means the catalog covers everything from serial 14510004 onward, but within each section you’ll find sub-ranges like “14510004~14512398” for the first rubber belt version. If you skip verifying your machine’s S/N, you risk ordering parts that were superseded or changed mid-production. The manual makes it impossible to mess up as long as you read the column. I’ve seen guys order the wrong track pin because they didn’t check the “Serv.” column for old vs new type. Don’t be that guy.

Audience Fit: Who Needs This Catalog?

If you own a Takeuchi TB145 and do your own maintenance — changing tracks, rebuilding the final drive, replacing hydraulic hoses — you need this catalog. It’s also useful for small shop owners who work on compact excavators. The DIYer who wants to save dealer markup on parts will find the exploded diagrams worth the price of the PDF alone. Beginners: you can match the part number on your old component to the illustration, then order. Professionals: you can hand this to a parts clerk and say “part number from page 5, line 11.” It saves billable time. One caution: this is a parts catalog, not a service or repair manual. For torque specs and assembly procedures you want the Takeuchi TB145 TB150 Technical Manual or the Takeuchi TB125 TB135 TB145 Workshop Manual. Those have the step-by-step instructions. The catalog gives you the part numbers to order while you have the machine apart.

Source Validity: OEM vs Aftermarket Documentation

This file is a direct scan of the factory Takeuchi parts catalog. The OCR excerpt shows “TB145 Book No. BK3Z010 S/N 14510004-” — that’s the genuine binder number. Aftermarket parts catalogs often re-number components or omit serial range notes. I’ve seen third-party lists that lump all TB145 belts under one number, which will get you a belt that doesn’t fit your machine’s undercarriage. The factory PDF gives you the exact part number, the correct quantity, and the serial range that it applies to. No guesswork. For a deeper look at how factory manuals differ from generic reprints, read this Automotive Industry Overview that explains OEM documentation standards. Also check Automotive Industry Overview for context on parts numbering systems.

VTEC System: What the Manual Covers

Wait — this is a Takeuchi compact excavator, not a Honda engine. But the indexing principle is the same: factory diagrams with callout numbers. The catalog covers the entire machine: undercarriage, turntable, engine electrical, hydraulic piping, cover and cab, hoe attachment, decals, and hydraulic devices. The engine electrical section includes starter, alternator, and wiring harness part numbers. The hydraulic piping section shows every tube, fitting, and O-ring. If you are rebuilding the hoe attachment, the “Hoe Attachment” chapter lists pins, bushings, and bucket linkages. 729 pages gives you a parts breakdown for every system on the machine.

FAQ: 4 Questions

Does this catalog include torque specifications?

No. It is a parts catalog, not a service manual. You get part numbers and quantities only. Torque values are in the service manual.

Can I use this to rebuild the engine?

You can use it to order every seal, gasket, and piston ring. But for assembly procedures, clearances, and torque sequences you need the factory service manual. The parts catalog gives you the components; the service manual tells you how to put them together. They are separate documents. If you want both in one place, look at the Takeuchi TB145 Parts Catalog for parts and pair it with the workshop manual for repairs. I recommend buying the pair if you plan to do a full overhaul.

What serial number range does this cover?

It covers from S/N 14510004 onward, with specific sub-ranges inside each section. The front cover states “S/N 14510004-” and internal tables break down by narrower ranges. Check your machine’s serial plate before ordering any part.

Is the PDF searchable?

The scanned document is image-based with OCR. Most page numbers and part numbers are readable by search, but you should verify visually. If you need the exact page for an engine part, go to the index on page 1, find “Engine” section, then turn to the engine chapter for your specific engine model.

Stop guessing which part number goes where. Access the Factory Manual now and keep a copy on your phone or shop computer. Every time you tear down a Takeuchi TB145, you’ll have the OEM part number at your fingertips.
