Squeel In '96 SSEi Supercharger
 
Hey all. I'm back, with another Bonnie, and with another problem. I have had this '96 SSEi for 8 months or so, and other then the starting issue (which I never did get repaired...I just ignore it), it has been pretty good. However, I have been hearing a "squeal" noise coming from the supercharger for a few days now. I have spent the past few days also searching around here, and though I found many good post's, I couldn't find anything on this particular squeal.
It's coming from the actual pulley on the supercharger. It "squeals" basically all the time now, and squeals louder if I give it a little gas (not flooring it...just accelerating). If I spray the pulley itself with WD40, or a similar liquid, it stops.
Any suggestions? I just put a new belt on a week or so ago (boy, that's really fun!), as well as a new pulley. I have also taken the belt off and moved the supercharger pulley by hand. It seems to turn as it should. There isn't any play that I can find, and I have tried the "pull in and out on the pulley like you are pulling it off the car" mentioned in several post's as well. There wasn't any play there either.

Any suggestions, as always, would be greatly appreciated. :)

Do you believe the belt is squealing or the bearings in the nosedrive are bad?

How's the oil? Have you driven the car without the SC belt yet?

To answer Bill's question, it's not the belt, that I can tell. The belt is brand new, and I only squirt the WD40 on the pulley itself, getting none on the belt (to make the noise go away). How would I go about checking the bearings in the nosedrive? As I said, I have read quite a bit about the supercharger, but there is still a lot for me to learn.
To answer Willwren, the oil in the supercharger is full. That was one of the first things I checked. When I bought the car, it was low, but it only took 1/4 or so of a bottle of supercharger fluid to fill it back up.
Thanks again guys.

Check by running it w/o the supercharger belt.

You can untension it and ensure it's tied out of the way w/o taking it out of the motor mount. ;)

My apologies to Willwren. I forgot to mention that I haven't driven the car with the belt off, but I have ran it for several minutes with the belt off, and I didn't hear the noise.

Sorry Bill, I could have said this in my last post, but I didn't see your post before I replied. You guys are fast! :D
Anyhow, I have ran the car without the supercharger belt, and there is no squeeling noise, at least, none that I heard. I am going to go and double check it though when the car get's back home in around an hour or so.
Thanks for the pointer about not having to take the belt off too. Man, that isn't a fun job, espically when doing it at 11 at night in the pouring rain!

When you say you sprayed oil at the supercharger pulley...do you mean behind it..so that it got into the bearings or on the pulley so that the belt quieted down?

orbitz 10-18-2006 09:37 AM

That's the odd thing. I sprayed the pulley itself (at the front, where the air bolt is), and I am 99% sure I didn't get any on the belt. I have never tried spraying any in through the back of the pulley.
Can you recommend a way to rule-out the belt? It doesn't sound like a belt squeal, but if I can rule it out, it's one less thing to worry about. :)

BillBoost37 10-18-2006 09:40 AM

Spraying the pulley there will have no effect on the bearings. They are behind the pulley and inaccessible the way you did that.

Please look at the belt path and make sure everything is lined up. While you are doing that..please take a picture of your belt tensioner markings.
