Takeuchi TB015 Parts Catalog – Your One Source for Factory Part Numbers

I’ve been wrenching for twenty-eight years, and I’ll tell you straight: nothing wastes a day faster than pulling a part off the shelf that doesn’t fit. You need the Takeuchi TB015 Parts Catalog if you want to order the correct components for that compact excavator without playing roulette. This is the factory book—207 pages of exploded diagrams, OEM part numbers, and the exact quantities you need. No generic cross-references, no blurry reprints. This is what Takeuchi issued to its dealers.

Look at the opening pages. Page 3 shows you exactly how to read the manual: top half is the explosion drawing, bottom half is the list. Part numbers are right there next to each item. If a part isn’t for sale, it gets an “X” in front of the number—no guesswork. The manual covers serial numbers 1153001 through 1158122, so you know it matches your machine. I’ve seen guys order a bolt one size off and lose an afternoon. This catalog stops that cold.

You get the whole breakdown: undercarriage, turntable and control levers, engine and electrical system, hydraulic piping and tank, covers and cabs, hoe attachment, decals and tools, and the entire hydraulic device section. The Engine & Electrical System chapter alone covers the 3TNA72L engine—everything from the cylinder block to the starter motor and generator. Need a gasket set? It’s listed. Need the fuel injection pump? It’s in there. Every section has its own parts index so you can flip straight to the component.

Undercarriage and Track Components – Correct Part Numbers for Every Roller

The undercarriage section runs from the lower frame to the crawler belt, track roller, front idler, track adjuster, travel device, and dozer blade. Each component gets its own exploded view. You see the exact arrangement of bolts, seals, and rollers. When you order track adjuster seals, you get the Takeuchi part number—not something that “might work.” I’ve had customers bring me aftermarket adjuster cylinders that leaked because the bore dimensions were off. This catalog lets you cross-check before you buy.

Engine & Electrical System – Exactly What’s Inside Your TB015

This part of the catalog is critical. It covers the 3TNA72L engine with 17 sub-sections: cylinder block, gear housing, mount flange and oil sump, cylinder head and bonnet, intake manifold and air cleaner, exhaust manifold and silencer, camshaft and driving gear, crankshaft and piston, lubrication system, cooling system, fuel injection pump, governor, injection valve, fuel pipes, starter motor, generator, and an optional gasket set. The Electrical chapters include control box, engine control, and multiple wiring diagrams for cab and canopy versions. For Australia, there’s a separate electrical page (ELECTRICAL 1 FOR AUSTRALIA). That level of specificity saves you from ordering the wrong alternator or harness.

3 Sections of Hydraulic Device – Pumps, Motors, and Cylinders

The hydraulic device section lists every valve, cylinder, and motor. Swivel joint, control valves 1 and 2, pilot valve, sub valves, solenoid valve, stop valve, shut-off valve, selector valve, boom cylinder, arm cylinder, bucket cylinder (two entries), dozer blade cylinder, swing cylinder, spanner cylinder, telescopic cylinder, and travel motor (six entries) plus slew motor (nine entries). And the hydraulic pump. Each part number is listed with quantity and interchange notes. When you need a swing cylinder rebuild kit, you get the factory part number. No guessing.

Does This Parts Catalog Include Assembly Torque Specs?

No—this is a parts catalog, not a service manual. It gives you exploded diagrams, part numbers, and quantities. Torque values and service procedures are in the Takeuchi TB015 Workshop Manual. If you need troubleshooting steps or disassembly instructions, pick up the workshop manual instead. I’ve linked the relevant service manual sections below so you can grab both and have a complete shop setup.

How to Use This Catalog on the Job

You’re on site, the track adjuster is leaking. Flip to the UNDERCARRIAGE section, find TRACK ADJUSTER, look at the diagram, note the item number, read the part number. Call your dealer with machine serial number and part number. Done. No wasted trips. I’ve done this a thousand times. The manual also includes a parts index at the back—every part number listed in alphabetical order with page references. That’s gold when you’re hunting down a discontinued seal.

One warning: always verify your machine serial number. This catalog covers S/N 1153001-1158122. If yours falls outside, double-check. Also, pay attention to the “Chan.” column (change) and serial number notes—some parts were revised mid-production.

Source Authenticity: OEM Factory Print vs Aftermarket Copies

You can buy a generic parts diagram online for ten bucks. Then you end up with a hose that’s two inches too short because the drawing was rescaled. This is the original Takeuchi PDF—same print the dealers use. Automotive Industry Overview may tell you about supply chains, but this manual tells you exactly which part goes where. For more context, also see the Automotive Industry Overview.

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

Yes. Factory part numbers are universal—any Takeuchi dealer will accept them. Just provide the machine serial number.

Does the catalog include price lists?

No. It only lists part numbers, descriptions, quantities, and interchange notes. Contact your dealer for current pricing.

Why are there multiple entries for the same section like FUEL TANK or DECAL?

Those represent different configurations (e.g., canopy vs. cab, Japanese vs. export). Each variant has its own set of parts. Check your machine type to pick the right page.

I need a hydraulic schematic—will this help?

Not directly. This is a parts catalog, not a hydraulic diagram. For troubleshooting hydraulic circuits, get the workshop manual. But if you need the part number for a specific valve or seal, this is where you find it.

Stop wasting time on wrong parts. Access the Factory Manual and keep the correct part numbers at your fingertips.
