wobbling alternator pulley
Hello, maybe somebody could point me in a right direction. Recently I replaced alternator on my ISX CM870. Delco Remy SI34. I removed it from another truck. Today when removing the belt I noticed that if I rotate pulley by hand it kind of wobble a little bit from side to side. Why it could be that way? My old alternator doesn't have a key , so I didn't install any. Bad pulley? Bad alternator? Thanks!
