Takeuchi TB235 Parts Catalog

I have seen more than a few guys order the wrong parts because they guessed the number. A number from memory that turned out to be for a different machine, a later serial break, or a superseded part they could have cross-referenced in 30 seconds. That wastes billable time, ties up inventory, and usually means the machine sits. The factory Takeuchi TB235 Parts Catalog stops that. 531 pages of OEM part numbers, exploded diagrams, and compatibility codes that match exactly what Takeuchi shipped.

This is the same document a dealer tech pulls up when you call. No aftermarket typing errors, no re-hashed drawings, no missing interchange notes. It comes from the original file: TAKEUCHI_TB235_Parts_Catalog_en-ja-fr-de-44614017971.pdf. If you work on these mini excavators, you need this on your tablet or printed out.

Parts Catalog Basics: How to Read the Manual

Page 1 gives you the index. Page 2 through 4 explain the research system in English, Japanese, French, and German. That multilingual section is worth reading once because it shows you exactly what each column means – part number, description, quantity, and the compatibility codes (L, H, HL). The manual labels front, rear, left, and right from the operator seat facing forward. Sounds basic, but I have had arguments over which side is left. This kills the argument.

Each illustration has numbered callouts that tie directly to the parts list. No flipping back and forth trying to match fuzzy lines. The note section (page 4) warns you if a part has a supersession or a machine-specific restriction. Pay attention to that.

Ordering Parts: What You Need to Supply

The manual prints the required information right on page 4: machine model, machine serial number, part number, description, quantity of parts. If you walk into a dealer or send an email without the serial number, do not be surprised if the counter guy rolls his eyes. The parts catalog is serial-specific. This copy covers serial number 123500001 and up (models BG7Z004-1 and BG7Z004). Get the serial off the machine – it is stamped on a plate near the operator seat.

Machine Orientation – Why It Matters

Right and left are defined from the operator seat looking forward. If you have ever installed a travel lever assembly backwards because you guessed orientation, you understand. The manual includes a section on travel lever and swing pedal diagrams. Using the correct orientation saves you from ordering a second set because the mounting holes do not line up. I have seen it happen.

Takeuchi TB235 Parts Catalog – What’s Inside?

You get the full exploded view assemblies for the entire machine: undercarriage, swing system, boom, arm, bucket, hydraulic components, engine, electrical, and chassis. Each assembly lists the part number, description, quantity required per machine, and compatibility codes. For example, the engine section references the 3Tnv88-Bptb2 engine. When you need a specific gasket, you look up that assembly, find the number, and order it. No guessing.

Related manuals that pair with this parts catalog include Takeuchi TB235 Parts Catalog for cross-referencing, Takeuchi TB235 Workshop Manual – Section: Moteur for disassembly and reassembly torque specs, and Takeuchi TB235 Parts Catalog – Section: Engine 3Tnv88-Bptb2 when you need engine-specific breakdowns.

Part Numbering and Compatibility Codes

The manual uses a smart system. A part with code (L) can replace all earlier parts listed above it. A part with (HL) can replace those below. Multiple-part assemblies have uppercase/lowercase lettering to show interchangeability. This is not something you get from a generic aftermarket site. You also see the quantity column – if it says AR (as required), you need to measure or count. Respect the note on page 4: if a part number has an ‘X’ in the listing, it is not sold separately. Do not try to order it.

Does This Manual Cover Your TB235?

It covers TB235 mini excavators built from serial number 123500001 onward. If your machine is older than that, you need the earlier parts catalog. Check your serial plate. The model designations BG7Z004-1 and BG7Z004 are both included. If you are unsure, call a Takeuchi dealer with your serial – or just buy this catalog and verify compatibility once you see the index.

Why OEM Beats Aftermarket Parts Lists

Aftermarket parts catalogs often re-type numbers and drop the last digit, or they copy a superseded part without listing the new one. This manual is the original factory PDF. The same one the dealer uses. No translation errors, no missing Japanese script for the original part name. If you want cross-industry context on why OEM documentation matters, read Automotive Industry Overview or Automotive Industry Overview. The short version: factory specs eliminate guesswork.

Frequently Asked Questions

Is this manual only for serial numbers 123500001 and up?

Yes. It covers machines from that serial number onward.

Can I use this to find replacement parts for my TB235?

Yes. The manual is designed for exactly that. You look up the assembly (e.g., travel lever, swing pedal), note the part number in the illustration, cross-reference the compatibility code to see if the current part number replaces earlier ones, then order using the part number, description, and quantity listed. The manual also tells you which parts are not sold separately (marked with X). If your serial falls within the range (123500001 and up), you have the correct parts breakdown. Pair it with the workshop manual for disassembly instructions and torque values.

What does the compatibility code (L) or (H) mean?

(L) means the part can replace all parts listed above it. (H) means it can replace those below. (HL) means both directions. The manual explains this with Japanese and English text on pages 3-4.

Does this manual include part prices?

No. It only provides part numbers, descriptions, quantities, and compatibility. Prices are set by dealers. The catalog gives you the correct number so you can get a quote.
