    Ceramic bearings not suitable for heat transfer.

    I have heard that ceramic bearings are the ducks guts as long as heat transferrance is not required.

    The ceramic balls are a great heat insulator. The heat from inside can not be disapated to the outside, ei. from the supercharger shaft to the housing. And things do get warm down in that area due to air compression.

    It's probably a crock of shite but I'm hanging with metal roller bearings for now until someone has a good run with the ceramics.

    Hell, it's better than the damn bushes.

    Also the supercharger housing will have to be machined out to fit the roller bearing (ceramic or metal) assembly. No turning back from that.

    Just what I heard!! It sounds good in theory.

    Question! Were is that can opener for the worm tin?

    Are the supercharger bearings becoming a problem on the uprated SHO?

    My standard ones are badly worn already?

    I saw the extra oil line someone had fitted. Did that work ?

    YES.

    Recommendation to all: Take off the air intake and check the movement of the supercharger shaft.

    Easy to do and will save your expensive wheels.

    some have modded the bearing to allow better lubrication of oil.

    The ceramic clutch washers were the problem with the Sea Doo SC.
