    supercharger impeller seems to wobble???

    Ive just replaced the bearings in my b kit, and installed the impeller. With the front cover off and spinning the shaft by hand, and watching the impeller it seems to wobble a bit. It doesnt seem to run true to the edge of the housing, i checked the shaft for straightness it was fine, has anyone seen this with the aftermarket impellers?? Im concerned this might rattle itself to bits at high rpm.. Never had a problem with the charger before just doing routine maintenance..

    have seen it before and guessed that although the wheel is made slightly out of round it will have been balanced that way so cant be changed

    Doesn't seem right to me.

    Don't forget the impeller spins with 45000 rpm's in the superchargerhousing.

    A lot of damage can be done,if the impeller is not balanced ok.

    Just double check to be safe!

    Can u wobble it and make it touch down by hand? Thats scary, I am so glad my turbo pipes are getting welded together as we speak, a sc failure is no joke dude, its awful and you are right in the middle of the riding season, I would get some new bearings and take it from there. 2 weeks and $100 is better than a $2000 sc failure! Take it from me man.
