Kohler K361

[Eugen]

Interesting @Harry , but my 644 doesn't skip a beat even with a bucket full of sand or gravel. I've done this quite a lot last summer. But I always use it in LO range. Except when I moved sand with it, full bucket, full trailer behind, and almost 500 lbs of weight equipped on the tractor. Total weight might have been close to 1000 lbs. There was a 200 ft stretch going on a slight incline uphill, then the K321 was struggling, but I made it slowly to the top. I wonder though, what the limitation of the hydraulic pump , or hydraulic drive, or TCV pressure relief valve is.

Great job@Eugen !

If your not sure what to put it in maybe there’s another project tractor out somewhere that you can pick up.

It's alive indeed Dave! Took my time to put it back together. The valve guides will never become loose again me thinks. This engine can benefit from a temperature gauge so as to not overheat.

The valves and seats are nicely done now, clearance adjusted. New gaskets in a lot of places, got a full set from eBay the other day.

I'm kinda sorry to put it in the loader, seems like wasted power. Not sure at all what to do with it.

When I first purchased it the guy gave me a repair shops invoice that read what they did to rebuild the engine. Quite extensive with boring oversize piston new rings ect. At first never having a lbh before I took it easy in it to get use to using it. Last years I used it a lot and was not babying it at all. I use it in low gear unless have nothing in the bucket just traveling to get another load. I did get it stuck in the mud a few times because of the low hanging ballast weights. It usually just plows though the puddles but when the dirt is very wet it’s going to get stuck. One time I had to dump a bucket if dirt to push my way out with the bucket. Harry

I’m thinking of a 20 hp Honda that I have on the shelf in my shop for the 644 lbh. Harry

That 20hp Honda engine will make your 644 a beast!

Thanks @JSinMO ! There are some tractors here with broken engines. Just thought this engine could go into something more special. There was a guy on marketplace selling a thermo king 3-cyl diesel engine and I asked if he'd trade it for the k361 but he refused me. I'd have wanted that diesel engine for the tracked trencher. I think the k361 is a little underpowered for the tracked machine. I would want 20 hp minimum for that machine. There's a kohler magnum 20 for sale around here, that would probably be ok, but unless I sell something, no $$

Dave, I don't have a 226 anymore

I looked into the refer diesels , I don't like the way it add reads . Something is not right about that deal . Make your own K series 226 . out of a 22#

I saw the ad for the Thermo King diesels too... But I'm trying to convince myself not to get anymore "projects" until I have a house and a "REAL" garage...
