Park Ave 3.8 Ultra--- supercharger noise

[jagerEd]

My 95 PA Ultra has started making a bit of noise, seemingly from the
supercharger.
I've been told this is a common problem, due to wear in the nose piece.
Witht eh belt
off the noise is gone. I can feel a bit of slop as I rotat it back and forth
by hand.

So, what's the prognesis of this malady? I know it has to be fixed, but I
also know it's
expensive. How will it finally fail? Any downside to letting it go for a
while?
Can I fix it, or is it a job for the pros?

TIA

Sounds like the nose cone bearing are failing.
Apparently you can get the replacement bearing and take the nose piece off
and take it to a machine shop who will remove and replace the bearing. Just
have to buy a new gasket and put it on. If the rest of the supercharger is
making noise, then yes you need the whole thing reman'd. Otherwise save a
grand and just do the nose cone.
Do a search in usenet (use google groups) for nose cone bearing....
You will find a lot of tips and part numbers, etc.
Also look on thrasher-ep for the supercharger teardown.. lots of pics.
Apparently the supercharger compressor part lasts way longer than the nose
cone.

Thanks, Matt. Found a lot of good info. May try to rebuild the nose cone.

I'm familiar with alt.autos.gm, but what is thrasher-ep?

Thanks! That picture of the inside of the nose piece was especially helpful.

I just ordered the kit $25 from Magnuson Products. Since my car is a 95 Park
Ave ultra
the seal and bearing identified in the Mavin Mller article aren't
necessarily correct.
Has anyone else posted the correct ones? BTW, I tried to look up the CR 7965
Seal
Marvin gives in the Chicago Rawhide online catalog, but couldn't find it.

I'll post whatever I find out on the subject.
