Hi Gang! After a whole bunch of miles/years happily tooling down the road with the 62mm supercharger pulley, The bearing just failed. Started making a very loud screeching noise. Took the bolt and washer off and saw a lot of metal dust. Just wondering, as I can't remember, does the stock bearing work in the 62mm pulley? I've got an NSK supercharger pulley on order from Needswings, but that was before I gave it some thought and started wondering if the outer diameter of that bearing will fit properly in the 62mm pulley. Any input would be appreciated.

BTW, how many people who purchased the 62mm supercharger pulley are still running with that setup? I've had mine on the car since the 2012 initial group buy (think I was #1 on the list).

One more thing... The side of the pulley that holds the belt looks great. The backside that connects with the magnetic drive wheel looks kind of rough. It is no longer smooth, but has grooves carved in it. The mating surface on the supercharger is similarly grooved, though in a reverse fashion. Attaching an image file for folks to look at. I've been running this pulley for about 100,000 miles. Figure I should consider this a problem, but wonder what I can do about it. The shiny rings is the groove (including that duller ring at the center most portion of the surface). The darker rings are the original surface. All thoughts and ideas are welcome.
