ACman 7,505 #1 Posted February 6, 2018 (edited) I came across a screaming deal on a K91 year reduction engine. $40 said ran last year. I’m assuming the crankshaft on the pto side is different. Are the blocks the same ? My question is could I use a crank out of another K91 (I think I have two) . I have one engine that my exhaust port just designated making it useless. I’d be sure to check clearances (std. -.010 ) on crank and rod . My thinking is you can never have to many K91’s around especially at this price .
