bean 85 #1 Posted July 16, 2013 what is needed to swap a pto setup from a magnum 10hp kohler to an magnum 8hp kohler? I assume the only difference is the drive pulley itself, because of the shaft size differences. are the 2 different drive pulleys drilled & tapped the same for the backing plate, etc?

Kelly 1,033 #4 Posted July 17, 2013 Only the bore for the shaft is different, all else is the same, change the pulley and the PTO sleeve and then you will need the correct top bracket for the engine for the PTO hoop Share this post Link to post Share on other sites
