Smaller Upper Pulley 84mm bearing bad need part#
Just about 2500 miles on it and bearing is making noise,thought it was my tensioner bearing so changed that and still noise ,so with it idling I CAREFULLY slowed down supercharger to a stop as it has some slight parasitic drag and noise got louder , also with this low mileage it shouldn't be making noise already has anybody else had to change out this bearing on this pulley ? And need part number thanks

wow 2500 miles is pretty low for the bearing to fail...

If you struggled on the install and the pulley didn't go on smoothly and you banged on it you may have damaged casing for sealed bearings. I had a tough time trying to install a cold pulley on a hot car even hours after I thought it had time to cool. The old pulley slipped right off but then, they were at the same temp. I resorted to put ice on the supercharger shaft until the pulley slid right on and all the way back like butter.. Could have waited overnight but I started the job at work on my breaks and had to finish it...
