How to remove Alpina B7 Supercharger Clutch (with Installation Tool) when replacing bearings.
If you are experiencing excessive supercharger pulley noise, wobbling or screeching - you most likely need to replace your pulley/clutch bearings. In this video, I demonstrate how to remove the clutch assembly in preparation for bearing replacement. Alpina recommends bearing replacement every 3000 engine operating hours or 60,000 miles (100,000 km).
Alpina B5/B6/B7 supercharger pulley bearings used to be available from BMW as part of serviceable kit (p/n: 11657973081). Unfortunately, they have been discontinued and are no longer available. I offer original-spec OEM clutch bearings and the Installation Tool for purchase. [ Ссылка ]
Also available is a comprehensive 9-piece Supercharger Oil Seal rebuild kit. This kit is used for servicing the supercharger, replacing the internal seals and stopping oil leaks.
