Engine Swap

Hi all, new to the site. I just purchased a property that came with a 420 crawler, 1957 I think, no serial number. It had antifreeze in one cylinder, upon further inspection I found a crack in one cylinder. I will likely fix that but in the mean time I am wondering if there is any readily available engines that can be swapped into this machine.
Thanks, Dave

Do you mean another 420 engine?

No, I hope to sleeve and rebuild the original engine. I just wondered if there was something else more modern to bolt up with or without an adapter plate so I can use the dozer for now. Hopefully the rest of the machine is operational, I am told that it is.

By the time you cobbled anything modern, you will spent more time that it will take to rebuild the one you have. If you don't want to rebuild yours, I have a long block here that came out of a good running crawler.

I always wondered how a Kubota 3 cyl. diesel would power these old crawlers.

Hi,

Pretty much the same as the 3 cyl diesel powers the 350.....

Too much power leads to too many broken parts! gregjo1948
