Mitsubishi 6D14-T, 6D14-15, 6D14-16-T Parts Catalog – 328 Pages of Factory Part Numbers

I’ve stood at parts counters with a broken ring gear in one hand and a blurry aftermarket catalog in the other. Waste of time. If you’re working on a Mitsubishi 6D14-T, 6D14-15, or 6D14-16-T industrial engine, you don’t want to guess which seal fits which serial number range. This Parts Catalog is the factory document – 328 pages of exploded diagrams, genuine part numbers, and the kind of detail that keeps your machine running instead of waiting on the wrong gasket.

Why a Parts Catalog Beats a Service Manual for Ordering

A service manual tells you how to torque the head bolts. A parts catalog tells you which head bolts come in which kit. Two different jobs. This catalog lists every serviceable component for the 6D14-T, 6D14-15, and 6D14-16-T – from the fuel injection pump down to the last O-ring. If you’ve ever installed a “close enough” part and watched it fail under load, you understand why genuine numbers matter. The catalog breaks down each engine model by application, so you can match your engine number to the correct illustration. No hunting through generic categories.

What’s Inside – 328 Pages of Factory Data

Page 1 carries the marker insert for rebuilding the PDF or printed document. Page 3 shows the title: “MITSUBISHI DIESEL ENGINE PARTS CATALOG MODEL 6D14-T.15.16-T (FOR INDUSTRIAL USE)”. That’s the spine of the manual. The general information on page 5 tells you how to order: part number, part name, quantity, and engine number. They even include a table of applied models – for example, the 6D14-T goes into power shovels like the RK200, while the 6D16-T fits the RK250. Every section is organized by engine variant, not by guesswork.

You get exploded views of cylinder heads, pistons, crankshafts, fuel systems, cooling, lubrication, and electrical. Each callout ties to a part number that’s still current in Mitsubishi’s system. This isn’t a reprint from a third-party aggregator – it’s the exact PDF Mitsubishi Motors Corporation released under part number 98318-81005. The document even includes a notice in Japanese and English about using genuine parts. I don’t care how good you think an imitation piston is; the factory says don’t use it. That notice is on page 4, and it’s worth reading twice.

3 Systems Where the Parts Catalog Saves You Mistakes

1. Fuel injection system – Injection pump, nozzles, delivery valves. One wrong plunger and the engine won’t carry load. The catalog shows the exact pump variant for each applied model.
2. Turbocharger assembly – Oil lines, gaskets, and turbine housing. Different part numbers for the 6D14-T vs. 6D16-T. Not interchangeable.
3. Cylinder head and valve train – Valve guides, keepers, and spring retainers. The catalog lists parts by engine serial number prefix, so you don’t end up with a 6D15 part in a 6D14 head.

I’ve seen shops lose a whole afternoon because they ordered a water pump from a generic “fits all” listing. This catalog kills that risk. Every part number is specific to the engine model, application, and production range (February 1986 and later).

Genuine vs. Imitation – What the Factory Says

Page 4 of this catalog carries a warning I wish more people paid attention to: “Imitation parts are not recommended from the viewpoint of their material and manufacturing method which are entirely incomparable with those of genuine parts.” That’s straight from Mitsubishi. They’ve tested their stuff. The aftermarket stuff hasn’t seen a dynamometer. If you’re rebuilding a 6D14-15 for a piece of equipment that earns money, don’t cheap out on the internal components. This catalog gives you the genuine reference numbers so you can walk into a dealer or order online with confidence that the bolts don’t stretch.

Before you ask – yes, this is the same catalog Mitsubishi dealers used. You can verify the part number 98318-81005 (also 98318-80010) against official records. That’s the OEM document. I don’t touch aftermarket parts catalogs on principle because they’re incomplete. This one comes from the source.

Does This Catalog Cover Your Engine? – Applied Models

The general information section lists the following engine models and their applications:

• 6D14-T – Power shovel (6D142CT-YJ01, 6D142CT-YJ02 cold region), RK200 (6D142WT-KS01)
• 6D14-15 – RK160 (6D151WZ-KS01, 6D151WZ-KS02)
• 6D16-T – RK250 (6D160WT-KS01)

If your engine falls into one of those groups, you’re covered. The catalog references the specific applied model number, so you can match your machine’s serial tag to the correct parts page. No ambiguity.

You can also check related manuals for other Mitsubishi diesel platforms: Mitsubishi 6D14-T 6D14 6D15-T 6D16 SK330 2001 Workshop Manual OEM Specs covers service procedures, while Mitsubishi S3L2 2009 Parts Catalog – OEM Factory Specs works for smaller engines. If you’ve got a larger-displacement application, Mitsubishi S6A3-PTA PTK 1991 Parts Catalog – Factory OEM Specs might fit your needs.

FAQ – Common Questions on This Parts Catalog

Is this a service manual or a parts catalog?

Parts catalog only. It lists part numbers, quantities, and exploded diagrams. For torque specs and repair steps, get the matching workshop manual.

Will the part numbers still be valid if my engine was built after 1986?

This catalog covers engines produced in and after February 1986. If your engine number falls in that range, the numbers are correct. For later updates, Mitsubishi issued supplements – check the OEM database if your engine is newer than 1990.

How do I order a part using this catalog?

Locate your engine number, find the correct section (e.g., cylinder head), note the part number and name, then contact a Mitsubishi dealer or parts supplier with that info. The ordering procedure is detailed on page 5.

Can I print this PDF and take it into the shop?

Yes. The PDF includes marker pages for duplex printing. Print the whole 328 pages or just the section you need. The diagrams are clear at 100% zoom. I recommend printing the fuel system section and laminating it – grease and paper don’t mix.

You don’t need to hunt for part numbers across three different websites. This catalog puts them all in one place, verified by the same engineers who designed the engine. If you’re tired of getting burned by imitation parts or wrong listings, get the factory reference. Access the Factory Manual.
