    Reinstalling supercharger

    Received my supercharger today from having it rebuilt by Jerry. Looks GREAT!
    Do i simply bolt it together & rip on or do I grease the gears or something then put it together?

    Put a little grease or anti seie on the shaft at the 2 Oil O-rings,Slide it in,bolt it up and run it through the RPM range a few times to break in the clutches,,,after that run it as you normally would and have the slip checked/reset after around 10 hours...Then she should be good to go for awhile..

    Personally, anytime i put in a new or rebuilt charger, I put it on the bench, clutch up and pour some engine oil down the shaft until its full. Then rotate the shaft by hand to distribute the oil down around the new bearings.
    Then pour out the excess oil and install the supercharger in the ski.
    I don't ever want to start a charger dry from new or a rebuild. Bearings on startup go from Zero to 20,000 rpm on startup. How long before oil reaches the bearings?

    Maybe im being over cautious, but I take safe than sorry route.

    last winter i helped a friend restore a hurricane sandy ski he had bought had to run 16qts. of oil though it to clear it up during the process we had pulled the supercharger to get rebuilt so i made a Plexiglas cover it bolt over the hole to cover it up so we could idle the engine the first time i started it i thought shit the oil pumps not working it was a good 10 seconds or so before oil was squirting at the window so when they said don't go WOT on a cold engine they mean it.

    Yep. Got lost on the terminology. During normal operation does this sealing surface get lubed with oil? If not how is it maintained during the high rpms? Cant imagine this little grease upon re-installation being the only source of lubrication?
