K3M Mitsubishi Engine or Block

[Short Game]

Anyone have one they don't need?

I found a complete rebuild kit here: EngNet - Mitsubishi Diesel Engine Parts - Parts Supply Corporation


But I'm taking for granted that you need a block, so not sure my link will help much.

That one is a 'D' series, not sure if it is interchangeable or not. But you did better than me..........the best I can find is a 4 year old thread on another forum, with a 'dealer' not being able to find one.

I got a rush from that ad. It looked right but was a 52 cu. in. 18hp and mine is a 91 cu. in. 27HP. There are 30HPs out there with turbo. This same engine was used in the 1991 Case IH 1140, the Cub Cadet 727* series, and Mahindra 2816s, and some European pavement roller I saw once online.

Thanks for trying. I have been digging for one for a over a year now.

When I went to Cub Cadet right after it happened, a dealer mechanic said he'd look into it for me. He called me back later and told me that I had a paperweight. Still hopeful.

K3M Mitsubishi gets many hits for the airplane they gave the same model number.

You need to get a block number and check it against the one advertised. That possibly could be the same block as yours, except your 91 cu. in. may be produced by a slightly larger bore, and a longer stroke crankshaft. You should try and find more exacting specs, such as bore and stroke for both engines. Good Luck!:thumbsup:

What engine parts do you now have?

I have a complete engine with a cracked block.

I can almost guarantee the K3D and K3M are not the same block. I would PM or call TBN member bruce1966us (Bruce Laten) 931-455-6999 and see if he has one or would put you on a waiting list for the next complete engine he gets. Chances are a complete engine will be as much or less than a block from most suppliers....he is very reasonable on prices. You could also get on Alibaba and check with some of the Asian engine suppliers. I was recently quoted $850 + $350 SH to NY or west coast port for a K3F from this guy P.S.P AUTO 2009 Co.,Ltd. - Used agricultural engines. They aren't VN rebuilds, they are original runners pulled from various equipment with sometimes unknown hours. However most engines appear in unmolested original condition and pretty clean/well maintained. For the prices I've seen on "rare" engines.....worth the "risk".

The other avenue is to go through tractor salvage yards and see what they will quote you on an engine or block. As well as the machines you mentioned, the K3M was used in Cub's 7300/7305, Mitsubishi MT300 and CIH 275 models. I have had great experiences with West Kentucky Tractor Parts - Kevil, Kentucky and they list an IH275 and MT300 in their dismantled inventory currently.

I appreciate the help though those are old links for me, as I am a veteran of this search. There are no short-blocks from what I can find. I can get everything except a block. I posted this thread because it seems about the only chance I have. I missed one on Ebay once, and it went off at a very reasonable price. I am on a small pension with nothing much for reserves. I will need a good deal to make it work out. I sure would like to have that Cub Cadet working for me again, as it was better in many ways than the 41 HP I have now, and far better on fuel. I have a bizillion hours in fixing that old machine and have learned pretty much how not to break it. I hate to see it sitting there.

If I can't fix it, I will put it back together and run it with the crack. It only gets water in the oil when it sits, so I can run it and drain the block and radiator every time. It gets lube oil in the water when it runs, so that will be the cost of doing business. Obviously, the crack is between the oil pump output and the water jacket, and apparently it is a small crack. The main oil gallery in the casting runs the length of the block along the right outer bottom corner of the water jacket, with a small line forward to the timing gears, and larger one to the rear. I don't know where else in the block there are pressure lines near the water jacket, so I assume that line in the casting is where the problem is. Water pumps should last well, running it that way.

Is it possible to post a few pictures of the cub cadet with the engine removed so that maybe someone might come up with a good idea of a possible engine replacement other than the K3M engine. Are there any other forums devoted to your Cub Cadet that others have encountered the same situation, and subsituted another engine? What model and year Cub Cadet is it?

Is it at all possible to weld, or braze the crack? Any pictures of the crack in the block?

Here's a listing for a parts machine kind of close to you in Tangent OR. CASE IH 275 Parts, CASE IH 275 Machine Salvage, CASE IH 275 Dismantled Machines At TractorHouse.com. No idea what shape the block is in, what you are wanting to spend or what $$$ they would ask but thought I would mention it.

Ever considered an engine swap as IH3444 mentioned? You could lookfor a cheap running engine from a slightly different series that might (likely would) work. Something like a K3H or even an S3L2 that was used in the Cub 7260/5 tractors and Toro 5300 ReelMaster( spec'ed out at 32 HP in the Toro :thumbsup....just a thought and a way to expand your options/something to keep your eyes out for.

I could not determine which engine that Case IH has.

The crack is somewhere internal. Can only guess where it might be. As far as another block design, there has to be steering and hydraulic pumps, the forward frame would have to be made to fit the block. There is mating to the clutch and drive gear. To change engine types brings in huge complication. Later models of this Mitsubishi build used physically smaller block engines. One of these engines would surely mate to the transmission, but everything forward would have to be refitted, or replaced with later model parts that would probably cast half a tractor's worth.

I've been looking at that Case IH 275 at tractordata.com and it does look like it might be the same block. So, thanks for that lead.

On edit, have one source that says the 275 has the K3M engine.

Off to the salvage yard sites.
