140 hi clear; Kubota engine swap?

BSer · Aug 14, 2009

I have a 140 hi clear that i'd love to use. The engine is apart with a bad block;supposedly for 20 years and all the loose parts are missing.I'd really like to put a Kubota diesel in it. Has anyone done this? It seems to be a natural,physically it's a little smaller and I would use frame rails to support the front end. Everything else here is diesel. Any help or suggestions?

Bser: Watch this one, I think any modern day diesel engine small enough to fit in place of a IH C-123, will turn in excess of 2,000 rpm to generate the same power as a 140. With those kinds of rpm's on a hi-clear 140, you'd need GPS for backing up.

I've looked at this one on numerous ocasions, and the diesels I see are a D-166 used in IH 340. Possibly one of the IH British diesels, it's still a lot of work. I like these two as they simplify the hydraulic pump.

Your probably not going to improve fuel efficiency a whole lot. I just finished putting my 140 through 40 hours of front and rear cultivators in 2nd gear full throttle, and I averaged 2.8L of gas per hour. I had enough cultivator shanks on there, tractor was working hard. I don't think it would have had enough power for 3rd gear.

Go for it! If you can match up a bellhousing and clutch it should seem like a go. I'd like to put a mechanical injection Cummins 5.9L in my 1979 C20.
