    Supercharger oil hole???

    I Have to Superchargers and neither one has that oil hole on it, I guess it was added later, is it for draining the oil or getting more into it?

    I just rebuilt mine cause the bearing closest to the impeller went out, Just nervous it might happen again, and with oil only splashing on the gear in the PTO...

    The hole in the housing is to allow excess oil to drain out of the housing....Oil is slung into the bearings/housing by the flywheel..this hole was created when the X chargers came about...It was once thought that the hole was for oil to get into the bearings and people were capping them off only to find that that wasn't the case...in your case you don't have any relief holes so your pretty much out...As far as your bearing letting go??How many hours were on it???was it pre-mature or near the end of its time??(100 hours)..Usually there isnt any issue with oil getting to the front bearing unless the bearings were put in backwards...

    I replaced it with the newest kit and Yeah I believe it was premature Should of had about 30-40 hours on it, according to guy on eBay...

    I was worried cause it looks like it would be hard for the oil to make its way all the way in there to the last bearing.

    And I was cruising at about 8k RPMs for 10mins when the bearing went.

    Yup,used charger off E-bay.......who knows how long it sat or how many hours were really on it...although bearings have been known to have issues.....Buying a used charger from somebody you dont know,is a ticking time bomb as you have unfortionatly found out....IF ever buying a used charger from an un known source,ALWAYS plan on rebuilding it

    Are you suggesting that we cannot trust "The Guy on Ebay"?!?!?!? What's next, you going to tell me that my $150 eBay intercooler is crap?!?!?!?
