wheelhorsejoe 4 #1 Posted January 18, 2011 Hi, just wondering, I want to replace my wheel horse 1990 312H 12hp magnum motor. I'm looking at a Kohler command V twin 18 hp, shaft size is 1" x 3" will this work? Thanks Joe :banghead: Share this post Link to post Share on other sites
bitten 134 #2 Posted January 18, 2011 Hello and Im sure you can make it work. Measure your output shaft on the Mag. and see if it is the same. Im not sure on the different shaft sizes. Share this post Link to post Share on other sites
Kelly 1,033 #3 Posted January 18, 2011 You can find the PTO bushing to work on a 1" shaft fairly easy, but finding the 1" drive pulley for the hydro will be the hard part, they only came on a few tractors, early 80's work horse hydros with briggs engines, that pulley is VERY hard to get, I bought a whole junk tractor for the pulley.
