For those who have racked up a few miles on your car, and want to replace the bearing on your supercharger pulley but can't get the pulley off - it's due to the grease from the old bearing leaking onto the shaft, causing it to get stuck. giggitty.

Use a pulley puller with teeth, cost me $35AUD on ebay.

There's plenty of instructions around about the whole replacement process, the only part that was unique was this and now I share it with thee.
