Takeuchi TL150 Parts Catalog

You pulled the hydraulic pump off a TL150, and the tag is gone. Now you’re staring at a pile of steel trying to figure out which seal kit you need. Some aftermarket spreadsheet says “fits TL150” but you’ve learned that translates to “maybe.” The factory Takeuchi TL150 Parts Catalog is what you actually want—599 pages of OEM exploded views, part numbers, and interchange notes. It’s the same book the dealer’s parts counter uses, and it covers serial numbers starting at 21500004.

8 Sections, 599 Pages – Organized for Speed

The catalog splits into eight main chapters: UNDERCARRIAGE, MAIN FRAME & CONTROL LEVER, ENGINE & ELECTRICAL SYSTEM, HYDRAULIC PIPING & TANK, COVER & CAB, ATTACHMENT, DECAL & TOOL, and HYDRAULIC DEVICE. Each section contains exploded diagrams with callout numbers that tie directly to the parts index. You don’t flip through fuzzy repackaged PDFs—this is the original Takeuchi Book No. BT7Z006.

What About the Engine and Electrical System?

Three engine variants are covered in the catalog: the 4TNE106T-TBL, 4TNV106T-XTBL, and 4TNV106T-XTBL1. Each has its own sub-index with specific part numbers for injectors, gaskets, wiring harnesses, and sensors. The Electrical side includes the starter, alternator, and control module mounting hardware. You won’t find any generic “same for all models” shortcuts here—every listing is tied to the serial number range.

Decoding the Parts Index

The back of the catalog has a complete parts index organized by part number. Say you find a number stamped on a bracket—type it into the index and it tells you which section and figure that part lives in. The manual also explains how to read the compatibility codes (L, R, and asterisk markings) so you don’t order a part that only fits earlier machines. This isn’t a repair manual, but if you’re replacing a track roller or a control lever assembly, you need the right number before you touch a wrench.

Three Engine Variants: Which One Does Your TL150 Have?

Check your machine serial number first. The catalog lists parts for all three engine options separately. For example, the 4TNV106T-XTBL uses a different fuel injection pump than the 4TNE106T-TBL. The Engine section breaks down every gasket, piston ring, and valve train component. If you’re rebuilding the top end, you get the exact part number for the cylinder head gasket—no guessing based on engine displacement alone.

Source Validity: OEM vs. Aftermarket Reprints

I’ve seen too many parts catalogs that claim to be OEM but are actually scanned copies of reprints with blurry diagrams. This is the genuine Takeuchi file, Book No. BT7Z006, serial number 21500004 and later. The diagram quality is high enough to read the callout numbers clearly. The hydraulic pipe routing section on page 87—actually, the page numbers vary, but every figure is legible. If you’ve ever fought a hydraulic leak because you ordered the wrong O-ring based on a aftermarket chart, you’ll appreciate having the original factory part numbers.

Frequently Asked Questions

Does this parts catalog include torque specifications or service procedures?

No. This is strictly a parts identification catalog. It shows exploded views, part numbers, and quantities. For torque specs and repair steps, get the workshop manual.

How do I find the correct part number if I only have the machine serial number?

The catalog is organized by serial number range (starting at 21500004). Use the parts index at the back to cross-reference part numbers. If the serial number falls within range, the diagrams apply.

Can I use this catalog to order parts from any Takeuchi dealer?

Yes. The part numbers are factory OEM. Provide the machine model, serial number, and part number from this catalog to any dealer—they will source the correct component. The manual includes a Japanese-language section but all part numbers are international.

Is this the same as the workshop manual?

No. The workshop manual covers disassembly, assembly, and diagnostics. The parts catalog only lists components and their exploded locations. You need both for a full rebuild. The parts catalog is 599 pages; the workshop manual is a separate document.

You need the right part number before you order anything. Access the Factory Manual and keep it on your tablet or print the sections you need. No more cross-shipping wrong seals.
