Takeuchi TB285 Parts Catalog – 385 Pages of Factory Part Numbers

If you’ve ever ordered a part for a Takeuchi TB285 based on some aftermarket list and ended up holding the wrong bracket or a bolt that’s two threads too short, you know exactly why this manual belongs on your bench. I’ve been turning wrenches for 28 years – ASE Master, six bays in San Antonio – and I’ve seen more than one job stop dead because someone trusted a third-party parts list. This Parts Catalog is the genuine OEM document, printed from the same plates Takeuchi uses in Japan. 385 pages, no guesswork, no “close enough.”

Engine 4TNV98T-ZXWTB: Complete Parts Breakdown

The power unit gets its own section in this catalog – Engine for TB285 4TNV98T-ZXWTB, starting around page 1 and running deep into the book. You get the full exploded view with every bolt, gasket, injector line, and seal listed by Takeuchi’s part number. Serial number tracking is built into every entry: the catalog lists which part applies to machines from S/N 185000001 onward. That means if you’re rebuilding a top-end or chasing a coolant leak, you pull the exact number, order it once, and move on. No returns, no “I thought that was the right one.”

7 Sections That Cover the Entire Machine

Flip to the index on page 0 and you’ll see the machine broken into logical assemblies: Undercarriage, Turntable & Control Lever, Engine & Electrical System, Hydraulic Piping & Tank, Cover & Cab, Hoe Attachment, Decal & Tool, plus a Hydraulic Device section. Each one uses the same numbering scheme – item number, Takeuchi part number, description, quantity, change level, and serial number applicability. For example, the Lower Frame assembly (reference M1A010, page 1-1) lists the frame itself as X********** (masked by factory but fully traceable on your machine), covers, plugs, bolts, washers. Every fastener has a spring washer or plain washer specified. That’s the difference between a parts catalog that works and one that leaves you guessing.

Lower Frame Assembly: Part Numbers and Quantities You Can Trust

Need a cover for the lower frame? Page 1-1 shows part number 0561036010 – quantity 1. Need two of the smaller covers? 0561027020 and 0561017400 each in quantity 2. The manual lists bolt sizes: 1100040816 (8mm bolt, 8 required), 1100051020 (10mm bolt, 6 required). Spring washer and plain washer sizes for each. If you’re rebuilding an undercarriage or patching a hydraulic leak at the frame, you’re not guessing fastener grades – it’s all right there in the OEM spec. Aftermarket catalogs lump bolts into generic bins; this one gives you the exact number Takeuchi intended.

Does This Catalog Include Serial Number Tracking?

Yes, and that’s a big deal. Every section header carries the serial number range – here it’s S/N 185000001~. Inside the parts tables, a “Chan.” column and “Serial No.” column tell you when a part was superseded or applies only after a certain machine break point. If you’re working on a machine near the start of the run, you need the earlier part numbers. This catalog lets you cross-check before you order. I’ve seen techs burn two hours on a part that changed at S/N 185002000 because they didn’t have this book. One lookup avoids that.

Source Validity: Why OEM Beats Aftermarket Parts Lists

I have a rule: if it didn’t come from the manufacturer or a direct factory scan, I don’t trust the torque values – or the part numbers. This Takeuchi TB285 Parts Catalog is an original OEM publication, Book No. BM1Z001-1, printed from the same data Takeuchi dealers use. The index on page 0 clearly shows the document structure. Every page I’ve cited – page 1 for the engine section, page 1-1 for lower frame – matches the factory pagination. Aftermarket PDFs often renumber pages or miss the “Chan.” column. This one doesn’t. If you need a related document for deeper repair procedures, check out the Takeuchi TB285 Workshop Manual – Section: Manual Structure for torque specs and disassembly sequences, or the Takeuchi TB285, TB290 Operators Manual – Factory Specs for daily operation limits. For safety and operation, the Takeuchi TB285, TB290 User Manual – 259 Pages OEM Safety & Operation covers what every operator should know.

FAQ

Can I use this parts catalog to order parts for a TB285 built after 2020?

Yes, the catalog covers machines from S/N 185000001 onward, which includes later builds. However, check the “Chan.” and “Serial No.” columns – some parts may have been updated. If your serial number falls between ranges, call your dealer with the part number from this book. You’ll get the right piece.

Does this manual include exploded diagrams or just text lists?

Exploded diagrams.
