I accidently installed my pulley too far in the shaft I had to remove it and reinstall it. When I was reinstalling it, it seemed like it went back in to easy and when I sarted my car the pulley started to come out and the belt started to come off I turned the car off and removed the pulley with my hand. Has this happened to anyone? I beleive that the pulley went bad. Could it be the pulley or the shaft?
