hey guys,

Has anybody ever tried to do this:

What do you think? Is it a good Idea? I would think it is. Seems pretty simple to do.
:)
Never tried it but...Does your charger not spin freely now? I can figure on some resistance but for how freely mine spins I personally am not concerned about losing .0025 Hp from the bearings. Maybe Guru Gadget can chime in if the stock SC'er bearings are of the same design or inferior quality.

Mine are Ok now I think, but I will be changing nose cone and I was going to do this just as preventive maintenance. Bearings do have a lifespan and the charger is spinning fast and generating much heat so I was just thinking that maybe it would be a good Idea.

Let me know what condition yours are in when you remove. Not to use you as a guinnea pig but someone has gotta do it first. I agree on the heat abuse they take. I laughed at the "special tool" you have to make. That's my kinda fun in the garage.

Well I don't know about that. I checked the link and it looks like some halfassed website that has no info as to where or who they really are with some pretty halfassed instructions. If you ask me, they are just interested in selling you some parts. If it were me, I'd just sent my blower down to the folks at Magnuson and let them have at it for a total rebuild if you think your bearings are shot. At least you get a warranty. I wondey why this guy doesn't sell the vaccum actuator. BTW you can get the oil from Magnuson in addition to any Buick or many other GM dealers.

Dick I am with you on Magnuson doing the job right. After reading the instruction it looked like it would be fairly easy. I don't know, I was just throwing that one out to see what people would think. What do you mean by a vaccum actuator I know this is a dumb question but is it the tool he is describing.

No it is an external part of the SC that has failed on me in the past. The actuator is the bit that bypasses the blower at off boost levels.
