Unless you already have the engine, Carrier transicold reefers use Kubotas, larger units use the V2203, which is what your machine has. Its pretty much a bolt in deal.Anything can be done if one wants. I think the biggest challenge would be rigging up a drive belt pulley beside making a custom bellhousing. That said, there is no small diesel I'd use over Kubota.
THAT is some good news to have. It seems hard to know where to (affordably) source these parts. IT truly helps to get that sort of info put into this forum. Hopefully, you just helped us all out, if we are ever in need. "Thanks", man!!!!Unless you already have the engine, Carrier transicold reefers use Kubotas, larger units use the V2203, which is what your machine has. Its pretty much a bolt in deal.
