Anybody have the part number for the bearings in the idler pulley on the P600B LT1 kit. It is for the 12 rib pulley. They have a little squeak right now so id like to get on it before its a problem. Im not getting any deflection of the main bracket and my pulleys are lined up perfect...........it just sounds like a high pitched squeak at idle. No belt throwing or chewing, just squeak. Thanks Eric L

 

Call procharger i am sure they can help you.

 

I took my 12 rib tensioner pulley to NAPA and got two new bearings for $2 a piece, in stock.

I had evidence of bearing races spinning in the pulley cause they fall right into place when the grease is cleaned off so I loctited them in there.. probably didnt do a damn thing to help that crap design.

 

I called procharger today and they said they didnt know the part number, and that all they could sell me was the whole assembly. And fwiw, I put a new bearing in my tensioner pulley (the LT1 factory one, not the procharger one) and I found it helped to knurl the pulley before pressing in the bearing, gave it a little more bite. I just used an all and some 40 grit paper. Thanks Eric L

 

If anyone is interested the NAPA part number is 6203 for the 2 bearings in the tensioner pulley. Eric L
