Anybody have a generic part number for an aftermarket idler pulley for the Blitz supercharger? Not the clutched pulley, the idler pulley that comes with the kit. Mine is making a little noise.

Contact Micro Image, as they tend to have some spare for the Blitz kits. If he doesn't have one, pull the pulley off and take some measurements of the bearing (or go to a local bearing shop) and you should be able to find an off the shelf replacement for it.

Noticed the bearing is clipped in. I'll try the bearing route. Any thoughts on the need for the ridges on both sides of the pulley? If I do replace the pulley, I doubt too many aftermarket or OEM for other vehicles will have those.

That's a good question. I would think that the ridges should not be necessary, since the water pump pulley not just doesn't have them, but actually has a rounded edge.

I removed mine, popped out the circlip, knocked out the tired bearing and sourced a new premium bearing from an industrial supply house for under $20.00.
The original bearing had gone dry. After twice repacking it I decided a new one was in order.

Do you have the bearing part number that you went with?

Sorry, can't recall offhand however it was the same code marked on the side of the original bearing. It was not a typical/stock item due to high temp seals so it was a couple days delivery to the industrial supply house.
