Takeuchi TB015 Parts Catalog – OEM Factory Parts Breakdown

Ordering replacement parts for a Takeuchi TB015 Parts Catalog compact excavator without the factory parts catalog is a gamble you don’t want to take. I’ve seen guys pull a part off, eyeball it, order something close, then spend a day waiting for the wrong gasket or injection pipe to show up. This Takeuchi TB015 Parts Catalog – 38 pages of OEM exploded views and reference numbers – eliminates that guesswork. You get the exact part numbers for the 3TNA72L-UTBZ engine, from the cylinder block down to the last gasket.

Cylinder Block and Main Bearing: Part Numbers You Can Trust

Chapter 1 dives into the Cylinder Block assembly. Every main bearing, bolt, and plug is listed with its Takeuchi part number. The exploded diagram shows where each piece fits – no guessing which flat washer goes where. Reference numbers match the parts list so you can order with confidence. This section also covers the Gear Housing (Chapter 2) and Mounting Flange (Chapter 3), which often get mismatched when people rely on aftermarket cross-references.

Does This Catalog Cover Camshaft, Crankshaft, and Valve Components?

Absolutely. Chapter 7 details the Camshaft & Driving Gear assembly, including timing gears and bolts. Chapter 8 gives you the Crankshaft & Piston set – pistons, rings, pins, and connecting rods. The Cylinder Head & Bonnet (Chapter 4) includes valves, guides, springs, and retainers. If you’re rebuilding the top end, you need these specific OEM numbers. Aftermarket catalogs often skip the valve guides or get the wrong spring rate. This catalog won’t.

Cooling System and Fuel Injection Parts: Avoiding Mismatched Orders

Chapter 10 (Cooling Water System) lists the water pump, thermostat, hoses, and the fan assembly. Chapter 11 through 14 cover the entire fuel system: Fuel Oil Injection Pump, Governor, Fuel Oil Injection Valve, and Fuel Oil Pipe. Each injection pipe has a unique part number – mix them up and you’ll have a no-start or a runaway engine. The exploded views show routing and clamp positions. For the governor alone, you get the spring, weights, and lever arm part numbers.

38 Pages of Exploded Diagrams and Reference Numbers

Every one of the 38 pages uses the same format: a clear exploded view with callouts, a table with reference number, part number, quantity, and notes. The Parts Index at the end lists every part alphabetically so you can cross-reference. No compressed scans or missing pages – this is a direct OEM file. Flip to the index and you can find the valve stem seal in seconds. The Starting Motor (Chapter 15) and Generator (Chapter 16) sections are there too, with all the brush and bearing part numbers.

Source Authenticity: Factory Takeuchi Documentation vs. Aftermarket

I’ve been burned by aftermarket parts catalogs that use generic drawings and wrong PNs. This is a factory Takeuchi document – the same one their dealers use. It comes from the original Japanese-English release, with both languages for key notes. The chart on page 1 warns that not all parts are standard equipment, and that part numbers may change without notice. That’s real OEM disclaimer language. When you order from this catalog, you’re ordering parts designed for the TB015, not a Chinese knockoff.

If you need diagnostic procedures or torque specs, pair this catalog with the Takeuchi TB015 Workshop Manual – Section: V. Troubleshooting – that covers the repair side. For a full repair guide on this machine, look at the Takeuchi TB015 1999 Workshop Manual – Compact Excavator Repair Guide. You might also want the companion Takeuchi TB015 Parts Catalog – OEM Factory Parts Breakdown for the complete machine layout.

No, this is a parts catalog only. It lists parts, not repair steps.
