I have purchased about 1/2 dozen rotors for crab distributors from 3 different suppliers in the past 3 weeks. They all are loose on the shafts, I have tried them on 5 different distributors and same results. I installed one and when I went to start the engine the rotor slipped off enough to hit the inside of the cap and broke in half. Since the rotor and shaft turn as one I don’t see how the shaft can wear. A older rotor about 15 years or so old has to be practically preyed off. In my limited knowledge I am guessing these rotors are made with mounting hole to large. Has anyone else had a problem ? Is there a remedy?
Thanks, Rick
