Reminds me of the trouble I had getting the boss off a tapered Victa shaft one time. It had rusted itself on there well and truly. As the motor was beyond repair anyway I resorted to cutting the shaft off and getting it in the vice. Even a large 3 arm puller would not budge it. The only thing that removed it was what speedy just suggested. I used heat and cold, heat and cold, then banged it with a hammer. Blasted thing still wouldn't move. While I was walking over to the other side of the shed to get a big hammer, I heard a plonk sound on the cement. The boss had dropped out! Must have finally had enough bashing.
