Mitsubishi KE75, K2B, K2C 1990 Parts Catalog

If you are wrenching on an old Mitsubishi diesel – KE75, K2B, or K2C – and the part you need has a name in Japanese or a number that’s been superseded three times, you already know the pain. I’ve been there. You call the dealer, they ask for an engine code, and you stare at a rusty tag. This Mitsubishi KE75, K2B, K2C 1990 Parts Catalog is the paper trail that cuts that guesswork. No aftermarket fluff. This is the same book Mitsubishi Heavy Industries printed in August 1990 for their own dealers.

Mitsubishi KE75, K2B, K2C 1990 Parts Catalog: Group Index Overview

The first thing you need to know is this catalog covers three engine families: KE75, K2B, and K2C. It’s 93 pages of exploded diagrams and part numbers grouped by system. The Group Index splits into 11 sections: Engine, Fuel System, Governor System, Lubrication System, Cooling System, Intake & Exhaust System, Electrical System, Instrument Parts, Tool, Repair Gasket Kit, and Optional Parts. Each section breaks down further by engine variant. For example, the Crank Case is split 01A for KE75 and 01B for K2B/K2C. If you miss that split, you order the wrong block. I have seen it happen.

Engine Group Sections: Crank Case and Cylinder Head

Section 1 of the Group Index covers the engine block itself. You get Crank Case (01A and 01B), Oil Pan & Gear Case (02A, 02B), Cylinder Head (03), Main Moving Parts (04), and Timing Parts (05). Each sub-section lists part numbers, quantities per model, and the critical R/P (Replaceability) symbols. That R/P column tells you if a new part will fit your old engine. Page 3 of the catalog defines those symbols clearly: O means both new and old work, X means only new on new engine, Y, Z, and # for special cases. Do not skip reading that page before ordering anything. Ignore it and you might get a part that physically fits but locks up because the design changed.

What the Fuel System Section Covers

Fuel delivery on these Mitsubishi diesels is not complicated, but the parts are specific. Section 2 of the catalog covers Fuel Supply Parts, Fuel Injection Pump, Nozzle & Nozzle Holder, and two separate Fuel Filter entries: 04A for 61PA and 04B for 61WM. If you have a K2B-61PA, you need the 04A filter group. K2C-61WM uses 04B. Mix them and you might get the wrong thread pitch. I’ve watched a guy strip a filter housing because the aftermarket book said ‘one size fits all’. It does not.

3 Major Systems You’ll Reference Often

Beyond the engine and fuel, three systems get daily use in the shop: Cooling System (Section 5) with separate Radiator sub-section, Intake & Exhaust System (Section 6) including Air Cleaner, and Electrical System (Section 7) which splits Starter and Alternator into multiple variants by engine suffix. For example, starters vary by 61TG, 61WM old and new. Page 2 of the catalog carries a warning from Mitsubishi about imitation parts. They are right. I have seen cheap starters fail in 500 hours. The factory part number is the only number you trust.

Governor and Lubrication: Don’t Skip These

Section 3 is the Governor System – only one sub-section, but critical for speed regulation. Section 4 covers Lubricating Parts. If you are rebuilding a K2C that sat for years, you want the exact oil pump gasket and filter from this catalog. The part numbers are engine-specific. Do not assume a K2B gasket fits a K2C. The crank case geometry is different.

Cooling System: Radiator and Cooling Parts

Section 5 splits into Cooling Parts (01) and Radiator (02). The radiator part numbers include the core size and mounting bracket variations for different applications – industrial, marine, tractor. If you are swapping a radiator from a 61A into a 61WM, check the R/P code. It might be a Y or Z, meaning you need new brackets.

Source Authenticity: OEM vs Aftermarket

This is a factory Mitsubishi parts catalog printed in 1990. It is not a reprint from a third-party. The OCR excerpt shows the original Japanese and English text, including the official warning about imitation parts. Every part number in here came from Mitsubishi Heavy Industries in Nagoya. Aftermarket catalogs often omit the R/P codes or list one part number for ‘all models’. That is how you end up with the wrong injector line. You need the real data. The catalog ends with a Parts No. Index and Effective Engine No. list so you can cross-reference your serial number. That alone justifies the price of admission.

Related Manuals for Your Mitsubishi Diesel

If you work on other Mitsubishi engines, check these factory catalogs: Mitsubishi S3L2 2009 Parts Catalog – OEM Factory Specs, Mitsubishi S6A3-PTA PTK 1991 Parts Catalog – Factory OEM Specs, and Mitsubishi 4DQ50 Parts Catalog – OEM Diesel Engine Specs. For broader context on diesel engine technology, see Automotive Industry Overview. Need to know the battery specs for a starter circuit? Automotive Battery covers that.

Does this parts catalog include torque specifications or repair procedures?

No. This is a parts catalog, not a service manual. You need the separate factory service manual for torque values and overhaul steps.

How do I identify which engine model variant I have for ordering parts?

Look at the engine nameplate or casting number. The catalog lists model variants on page 3, such as -61A for industrial standard, -61SA for SAMOFA, -61WM for sailing boat or generator. Then cross-reference your engine serial number with the Effective Engine No. table near the back of the catalog. The R/P symbols (O, X, Y, Z, #) tell you if a new part will fit your specific engine variant. For example, a starter listed for 61WM (old) may not fit 61WM (new) without modification. Always check the suffix and the effective number range before buying anything. I’ve seen a guy order a head gasket for a K2B-61A when he had a K2C-61SA – completely different part. The catalog separates sections by engine model, so if you ignore the suffix, you are gambling. Don’t gamble with a diesel engine.

Bottom line: if you need to order parts for a Mitsubishi KE75, K2B, or K2C diesel, do it right the first time. Use the factory documentation. Access the Factory Manual and keep it on your bench next to your torque wrench. You will never guess a part number again.
