View Full Version : Supercharger Bearing?

07-02-2009, 03:05 PM
Developed a squeak that sounds like it is coming from the supercharger pulley. Mechanic said it is the bearing. Can the bearing be replaced or do I have to replace more than just a bearing? Any advice is greatly appreciated.

pull your belt off the sc and spin the blower by hand.most bad bearings can be herd this way.if you dont hear anything try spinning all the other pulleys by hand to try to track it down.
if the bearings in your blower are bad you will need to send it out for repair.try calling stegie, when I had mine done they were the cheapest

Can you give me more info. on stegie. I called a place in Old Town, FL and was told they would rebuild for $150, does this sound fair?

I dont know of any company that would do it that cheap. I would be skeptical unless you can verify they are legit and have many happy customers. call Bob and see about there pricing. he at least has a good rep and knows his stuff

A rebuild is not that hard. A press to get the old ones out, some dry ice(or a freezer) and a oven that you don't cook in and use to heat medal is what you need.

I've kind of put it on the back burners because of other expenses, but I bought an old Eaton that wasn't in the best shape that I've been porting on and I'm replacing all the bushings in. Here are the kits I've bought.

Snot kit

Housing bearings

You probably won't need the housing bearings replaced unless your rotors look like their rubbing pretty bad. I was able to get them out with a Pilot Bearing Puller. See pictures.



Still if they will rebuild your snot for $150, and that includes all the bearings and seal then that might be easier for you, and doesn't sound like a bad deal for parts and laybor.

I have heard my engine make a howling sound at idle and the noise was definately comming from the Eaton. It did not last very long and soon returned a few week later. I open the oil fill port to see if there was oil in the gear box, yep, it sprayed out from being pressurized. That cured the noise about a year ago. Not sure what to make of the howling sound since it has returned but not as severe.
