Takeuchi TB015 Parts Catalog – Factory Parts Breakdown for Serial Numbers 1153001-1158122

You are ordering a part for a TB015, and the aftermarket catalog gives you a number that doesn’t match anything on the machine. Or the parts house cross-references something that looks close but leaves you with a bolt hole that’s off by 2 mm. That is exactly why this OEM Takeuchi TB015 Parts Catalog exists. It is a direct factory document covering serial numbers 1153001 through 1158122 – not a third-party reprint, not a scanned generic. Each part number, each hardware size, each washer count came off the same line that built your machine. I have seen what happens when a tech grabs a catalog from some online aggregator and ends up ordering a spanner cylinder that doesn’t fit. This 255-page file stops that nonsense.

Engine and Electrical System Coverage

The Takeuchi TB015 uses the 3TNA72L-UTBZ diesel engine. This catalog breaks down every gasket, every fastener, every electrical component tied to that engine. Chapter 3 of the Table of Contents is labeled “ENGINE & ELECTRICAL SYSTEM”. You get the exact part numbers for the starter, alternator, glow plugs, and the harness clips. No guessing which relay goes where. If you need the engine oil cooler lines or the injector nozzles, they are listed by serial number range. The index on page 3 tells you exactly which section to flip to – no flipping through 200 pages blind.

Hydraulic Device Section: 255 Pages of OEM Part Numbers

Section 8 of this Parts Catalog is dedicated to the hydraulic device – the pump, control valve, and swivel joint. Page 1-3 of the PDF (the LOWER FRAME parts list) shows the swivel joint assembly with part numbers like 1904007100 for the JOINT and 1913003950 for the BEARING. That kind of detail repeats across the entire hydraulic system. The catalog gives you the exact part number for each seal, each O-ring, each fitting. If you have ever ordered a hydraulic seal kit that came with the wrong size, you understand why having the OEM catalog on your workbench is worth the download.

Lower Frame Assembly: Real Part Numbers, Not Guesses

Look at the LOWER FRAME page (page 1-3 in the catalog). The table lists frame assy with and without the slewing lock – two separate part numbers. It gives you the bolt sizes: 1101051250 BOLT (15 pieces), 1101051275 BOLT (another 15), spring washer 1140020010 (6 pieces). That is not an approximation. If you try to source those bolts from a bin, you risk snapping them under track tension. The catalog also includes a serial number split: some bolts change quantity after 1154031. You do not get that fidelity from a generic parts site. This is factory data, period.

When you are rebuilding an undercarriage, having the correct slide part (0421013800 SLIDE) and the correct guide (0331011200 GUIDE) means the difference between a job that fits and one that binds. The catalog does not leave you guessing.

Who Needs This Parts Catalog

DIY mechanics who own a TB015 and want to order parts without paying dealer markup. Shop owners who need to provide accurate quotes to customers. Home garage enthusiasts who bought a compact excavator and are tired of cross-referencing part numbers that come back “unavailable”. If you are the kind of person who reads the torque spec before you touch a fastener, this catalog is for you. One real-world use case: you need the swivel joint for an older TB015. The catalog shows the joint (item 31) and the bearing (item 27) with part numbers. You order those numbers once, the parts fit, the machine goes back to work. No returns, no “this doesn’t match the photo”, no wasted Saturday.

Source Authenticity: Original Factory Documentation

This is not an aftermarket compilation. The file name itself – Takeuchi_TB015_Parts_Catalog_Section_HYDRAULIC_DEVICE_en-44614007512.pdf – comes from Takeuchi’s own system. The book number is PC3-101Z6. The serial number split is printed at the top of every page. I have been burned by enough third-party manuals that list wrong fasteners. This one is OEM. If you want to verify the context of why OEM documentation matters, read the Automotive Industry Overview on Wikipedia – it explains the engineering chain that produces specs like these. The catalog is 255 pages, spiral-bound in concept, and every page carries the Takeuchi copyright. You will not find a “reference only” disclaimer on page one. That is the difference between a service manual you can trust and a PDF you scroll past.

Frequently Asked Questions

Does this catalog cover the engine overhaul or just parts listing?

It is a parts catalog, not a service manual. It lists every component with part numbers and quantities. For repair procedures, get the Takeuchi TB015 Workshop Manual – Section: V. Troubleshooting or the Takeuchi TB015 Workshop Manual – Section: Iv. Hydraulic Units.

Can I use this catalog to identify parts for TB015 machines outside the serial number range 1153001-1158122?

The catalog is specifically indexed for that serial range. Takeuchi made production changes – for example, the lower frame bolt count changed at 1154031. If your machine falls outside this range, the part numbers may differ. You risk ordering items that physically fit but use different hardware. Always verify your serial number against the first page of each section. Using the Takeuchi TB015 Parts Catalog for the correct serial range is the only way to guarantee the part will match.

Download the Factory Manual and stop playing the cross-reference roulette. You will have the part number in hand before you pull the old component off the machine. That is how real work gets done.

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.

Frequently Asked Questions

Is this catalog the same as the service manual?

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

Can I use this catalog to confirm part numbers before ordering?

Yes. That’s exactly what it’s for. The catalog uses exploded diagrams and reference numbers to match physical components to part numbers. You’ll find sections for every major assembly: Cylinder Block, Gear Housing, Cylinder Head, Camshaft, Crankshaft, Lubrication, Cooling, Fuel system, Starting Motor, Generator, and a Gasket Set. The Parts Index at the back lets you search by part description. This is the definitive source for genuine Takeuchi parts.
