    S/C Noise (have factory rebuilt S/C ) Its noisy when i spin the gear ???

    OK Got a Factory rebuilt 185 HP S/C today in the mail today.
    Its tighter than the one i took outa my 185 HP Rotax (2005 Sedoo Challenger )
    Now the factory new one Growls abit when i spin it in my hands.

    The old one i took outa my engine spins and make almost no noise tho i know its got oil in it all through it.

    My Question is the Factory rebuilt one oK is that growl when you spin it by hand normal.
    Its very tight.
    Is there any oil inside theses S/Cs ?

    All perfectly normal!!!!

    I rebuild 20+ superchargers a week. All are hard to spin at first due to the seal being tight and no oil on the bearings. All make a dull "growl" sound when spinning the supercharger.

    When did you start doing rebuilds? I thought Mrs. Hulk was the charger superstar.....
