Well, I destroyed a PTO and the pulley above it but it's off. Never seen anything sezied like that was. I welded extensions onto a 2 way puller to get behind the PTO but still destroyed it getting it off. It left the collar and bearing on the shaft and after I got the engine off I cut those off with a side grinder. Normally I could have that engine off in a half hour, it turned into an 8 hour job. What a mess.
