Today i replaced bearings in the supercharger, added a polyphenolic gasket and an option b and the endplate.

The supercharger was dismantled, i put a new coupler in, the ZZP green one, along with some new needle bearings, cleaned the case up, assembled, and it spun very freely, no rubbing anymore and butter smooth. I put the car back together and started it. and this is when it went wrong.

The start up, went flawless,key in ignition, turn key, but the sound that came from under the hood was horrendous!!, i work around grinders all day and am fine,, this squeal was ear piercing! rough idle and sounded like there was something grabbing and stopping rotation?

Im not surew what i could have done wrong, since it was a disassembly and reassembly the same way.Please shoot me any ideas, maybe theres another thread about this? i googled with no luck, al my searches showed up as bad coupler, is it possible to put on backwards? mine is brand new and was a tight fit.

I have had the supercharger off before and work with a machinist that helped seat the needle bearings in the back of the case. When i drained my sc oil, about 3 oz came out, i put in about 4 oz, I know that this discussion comes up and all hell breaks loose n it, iv read from 3 oz all the way to 8, so i put a little more than what came out of new fluid, and reused about an oz of the old stuff, since the bottle i had blew up in my trunk.

 

learn to post in the correct section this is the performance section not my car is broke section that section is called Problems/Service/Maintenance

take the belt off and spin the accessories if they spin free then it must be in the belt
