Takeuchi TB228 Parts Catalog

Let me save you a call to the dealer. You’ve got a Takeuchi TB228 mini excavator, a part number you’re not sure about, and a parts counter guy who’s reading from the same screen as you. That’s where this Takeuchi TB228 Parts Catalog comes in. It’s the factory-issued parts book—443 pages—not some aftermarket copy with missing illustrations and wrong numbers. The index alone covers eight major systems: undercarriage, turntable, engine (the 3TNV82A-BPTB,BPTB1), hydraulics, covers, hoe attachment, decals, and the electrical system. Every exploded view uses reference numbers that tie directly to the part numbers on the facing page. No guessing what bolt fits the lower frame—page 5 shows the exact washer, bolt, and cover part numbers.

Takeuchi TB228 Parts Catalog: Engine and Lower Frame Coverage

Two sections you’ll live in: the Engine for TB228 chapter and the Lower Frame section. The engine chapter lists every component for the 3TNV82A-BPTB,BPTB1 power unit—injectors, gaskets, the whole rotating assembly. The lower frame spread (starting page 1-1) gives you the frame assembly, covers, and all the fasteners with thread size and length. If you need a specific bolt, the catalog tells you the part number and quantity. That’s it. No cross-referencing to another manual. Use your machine’s serial number (122800001 and up) to confirm compatibility.

Why Does an OEM Parts Catalog Beat Aftermarket Lists?

I’ve had guys bring me aftermarket parts lists printed from some forum. Half the numbers are superseded, the illustrations are screenshots of screenshots. This is the original Takeuchi publication—Book No. BE7Z001. The parts descriptions match what comes off the assembly line. If the factory changed a part at a certain serial number break, the catalog notes it in the “Chan.” and “Serial No.” columns. You can see it on page 5 for the lower frame covers. Aftermarket lists don’t carry that detail. They just dump a generic list and hope it fits.

443 Pages of Factory Part Numbers

That’s 443 pages, each one scanned from the original paper manual. No watermarks, no page removal. Every exploded view is legible, and the part numbers are printed in a sans-serif font that’s easy to read under a work light. The index on page 0-1 shows you exactly where to look: 1-UNDERCARRIAGE, 2-TURNTABLE & CONTROL LEVER, 3-ENGINE & ELECTRICAL SYSTEM, 4-HYDRAULIC PIPNG & TANK, 5-COVER & CAB, 6-HOE ATTACHMENT, 7-DECAL & TOOL, 8-HYDRAULIC DEVICE, 10-ENGINE. You can find the right section in under thirty seconds.

Match Your Serial Number to the Correct Section

Grab the serial number plate off your TB228. It’ll start with 122800001 or later. That serial number range is printed right on the cover page. This catalog covers that entire production run. If you have an older machine outside that range, this won’t match—call the dealer for the earlier edition. For machines inside that range, every part listed is a confirmed OEM number. Order from any Takeuchi dealer and you’ll get the right piece.

Lower Frame Assembly: Exploded View on Page 5

Page 5 (a real page from the catalog) shows the lower frame with callouts for the frame itself, three different covers, bolts, washers, and spring washers. The table below lists each part number, description, and quantity. Example: the frame assembly part number is not listed (marked with asterisks in the OCR) but the covers are 0371019020, 0431003600, and 0331018600. Two of those covers use M10 bolts and washers—exact specs are on the page. If you’re rebuilding an undercarriage, this is your shopping list.

What You Need to Use This Manual

A computer, tablet, or phone that can open a PDF. A serial number from your machine. That’s it. You don’t need a subscription or special software. The PDF is searchable by part number if your reader supports it. I keep a copy on a tablet next to my toolbox—beats flipping through a paper book that’s got grease on every page.

FAQ

Does this manual include torque specifications?

No. This is a parts catalog, not a service manual.

How do I find the right part number for a hydraulic hose?

Go to the HYDRAULIC PIPNG & TANK chapter (section 4). The exploded view shows every hose route with part numbers. Match the hose orientation and fitting type—the catalog lists the hose assemblies by length and end fitting shape. If your machine has been modified with aftermarket hoses, measure the original and compare to the listed part numbers. The factory hose will have the correct bend radius and pressure rating for the TB228 hydraulic circuit.

Can I use this catalog for a TB228 with serial number 122700000?

No. This catalog covers serial numbers 122800001 and up. Earlier machines used different frame and engine components.

Is this the exact same data the dealer uses?

Yes. This is the same OEM publication Takeuchi dealerships use to order parts.
