Take the belt off, spin the pulley back and forth by hand. Is there any play in it?

Are you handy with repairs? Then the easiest way is to take the supercharger apart and replace the coupler.

OK Ill do that. Is it possible its something else because when I put my ear up to it at idle it sounds louder in the body of the blower not at the nose cone area so like I sais Ill defenatally check for play but also woundered if the bearings could also make the noise. Once its fixed Ill add a 2.2-2.5" pulley and do they make a K/N drop in filter would that be sufficient? thanks

If it happens at idle it is likely the coupler. If you wanted to change out the bearings while you had it apart, it may be a good precautionary measure.

Take the belt off and rotate the pulley back and forth real fast. If it feels like there is some space between directions, it'* most likely the coupler which is real easy to change.

If it feels rough, it'* probably bearings and most likely coupler too. Parts are about $25 for the bearings and seal if I remember, $12 for the gasket Locktite 510 and $25 for a ZZ coupler.

I'd plan on the seal no matter what, if it'* not leaking now, it will.

On the weekend, I replaced the seal on the */C without taking off the charger. The two screw suggestion worked like a charm (Thanks, Hal). However, the nose is leaking again at the pulley. Now, it could be that the seal I installed didn't seat properly (I didn't have a deep socket handy which would fit the outer rim of the seal so I used one that would fit the inner).

Could improper installation be the reason? Is there another seal, inside the nose cone, that is to blame? I'd rather exhaust all possibilities before resorting to removing the charger.

Thanks.

Glad the 2 screws worked. Mine does not leak, but it was a metal cased one.

The first time I pulled th */C and replaced the coupler, mine leaked from the lower housing. I had used the proper Red locktite 512, but one of the circles around a bolt didn't seal and that was where the oil came from.

I would think about running a bead of sealer around the outside perimeter of the nose seal to see if that helps. Also clean off the eniter area with brake cleaner and see if you can pinpoint the source of the leak.

That'* exactly where my head was - sealing the outer edges. I may have tapped the seal in too much also.

I'll let you know. Your help is greatly appreciated.
