Driving at highway speeds yesterday and serpentine belt broke due to ac pulley bearing seizing up I'm assuming. I'd rather not replace the entire compressor however I need the entire assembly pack and cannot find a source for it. Denso 7seu17c for reference. Any help would be appreciated.

 

Over on bimmerfest.com, member "markch" did a very detailed write-up years ago on replacing just the pulley and he included where he sourced the parts.

Here's a list of markch's posts that include the word "pulley":
