I am trying to remove the alternator rotor on a 1983 shadow 750. I just got this engine off ebay because my crank was shot. I have so far heated the rotor uses a 5 foot cheater pipe only to break my ratchet, i know ishould have used a breaker bar, the bolt had left handed threads and i wonder if the guy i bought it from didnt know that and tried getting it off by turning the bolt the wrong way, because all the other parts were removed. Any way any of you guys ever had trouble getting this bolt loose or have any ideas about hou to procede. I dont want to break it then the crank i need is ruined.
