Hi all I am new to the forum, I've been a member for a while but never posted...I just finished removing my wifes supercharger on her 1999 slk 230, tricky to say the least but if was fun. I am a self tought mechanic of about 25 years and an experience aerospace/manufacturing/mechanical engineer. I am replacing the bearing with a set of 30x47x9 with a 4mm high temp. plastic washer/bushing that I made from materials from mcmaster-carr.com. I learned some of how to do the job from this site so thanks and I plan to contribute in the future. I am personally a bmw guy... sorry, I drive a 1999 M3.
