Yesterday my belt snapped and destroyed my sds idler pulley, the one that ripp sends you. I got my sds about 2 years ago. I called to see what the part number was so I can go get a new one, they didnt know and wont be able to find out until tuesday atleast. All he knew is that it comes from a bmw. Thats all I could find out. So does ANYBODY know the part number for this pulley? Please I hope somebody does.
