Supercharger question

94 PAU. Supercharger is bad, needs replaced. Can I still drive it? Can I disconnect the belt? Until it's replaced? Thanks

Can you be a little more specific about what is “bad” on your SC. Is it just making a noise, :uhoh: or has it seized up?:crying:

Sorry bout that. It's the bearings.

Supercharger belt runs with the AC and water pump. Looks like I need to just go ahead and replace it.

Ok different question now. Is it difficult to rebuild? And a recommended repair kit? Thanks!

I am sorry to here about your most recent failure! :crying: "If it weren’t for hard luck, you would have no luck at all”:shakehead Once again, I am sure you could handle the rebuild, if you have access to a local machine shop that could pull the bearings & seals and then press the new ones in. You might want to consider buying a used unit to install on the car, while you rebuild the original. Then you could rebuild the other used unit for a spare, or sell it on eBay.

Very interesting information HotZ28!

I also have a 94 PAU which needs a new supercharger. So PSE is the recommended remanufacturer?

When my nose cone coupler got noisy and leaky I got a rebuilt supercharger from these folks:

http://www.gmusedparts.com/

After a year or so it started down the same path as the first. Since the rebuilt has a lifetime guarantee, they sent me another one. Of course it
cost another $180 to have it installed.

Boy that is some GOOD information to have on hand! Thanks for taking all that time to find those links! Counting all my options for sure on this one!

Padriver, my :2cents: is PSE is a good recommended remanufacturer after reading this, or buy new. It could cost you an engine if it's not done right! :)

Have you ever rebuilt one HotZ? I'll need to know this BEFORE I decide to rebuild or replace! :)

Back in my more active racing days, I rebuilt quite a few "GMC 671" blowers; however, that is a different animal! If I had, the time and access to a shop press & bearing pullers, I would not hesitate to rebuild the M60.:grinno:

Unfortunately, when my PA started making a noise, my spare time was limited, so I just ordered one from PSE. The rebuilt unit arrived before mine failed and we just removed the old and replaced it with the new. That was about three years ago, and it is still working fine! I do need to change the SC oil again and will probably do that this week. I try to make the oil change an annual maintenance function, regardless of miles!

:grinyes:

Ok got some serious thinking to do. Thanks

Well, I certainly don't want to kill the engine and I also want to get it right the first time around. :)

I guess I will give PSE a chance. BTW, is the supercharger swap easy to do? Is there anything else to replace beside the gaskets? I figure it's really simple, but please correct me if I'm wrong. :dunno:

With the belt removed and turning the pulley back and forth I hear a clunk, not just spinning one way but when I turn in the opposite direction. There is no play in it. Is this normal? :confused:

You could have a bad coupler. Here is some good info on that subject. This is for the M90, however the M60 is very similar: How to replace an M90 snout coupler without removing the entire blower (http://www3.sympatico.ca/aepa/blowerinstall.html)

Thanks for getting that info, I'll letcha know what I find.

So far it's been a simple process. Not really alot of work to it. Just alot of cleaning, still waiting on coupler.

Saw on ebay a guy that rebuilds superchargers for the PA. Cost was $160.00 and free shipping. Uses all new bearing parts, and if you need it immediately, he will send you one with a core deposit of $140.00 (I think I'm right on that price...CHECK FIRST). Anyway, he is on the ebay site under a search for supercharger.

After looking at links provided and other threads in here, it appears my Supercharger with a rattle during idle in "drive" is more or less just the coupler and not really the bearings.
Interesting!:)

I took mine apart, pretty scared doing it after reading HotZ's post on 07-02-06, and found it just needed a coupler also. I had mine off in less than an hour and this is my first time doing it. All the bearings are in great shape, and no slack. Just a lot of carbon cleaning on the inside.

Vljenewein, thanks for that info. Do me a favor and go read the post on 7/6/06 by HotZ, read the links too. Tell me what you think after that.:)

I think I'll be getting ahold of the guy listed on the coupler links is what I think! :grinyes: That ebay member is 100% good and lives in Grand Rapids, MI. I LIVE near Fennville, MI about 45 miles from there. Price of supercharger oil plus the coupler is really an excellent deal for the money.

BTW I and vljenewein are one and the same. I popped in here recently after doing a search on google, and thought this was such a nice forum site I signed up with this name. The settings have changed since I first signed up. Now I have to be careful who I am signed in as, but the forwarding email I have on my other name "vljenewein" now comes to the same server as my regular mail, so get a double dose. :rolleyes: The layout had really changed, and I like it. It had changed so much I really didn't realize I had already signed up (registered) until I noticed in my saved "favorites" under links/forums that they both had the same icon for my web URL.

Anyway, my 1993 supercharger just rattles like there is a bad belt tightener bearing or some spare parts loosely rattling around in there some where. I was told by everyone that it was the supercharger bearing. Now I know different..

BTW you know the definitions of a helicopter? A collection of spare parts loosely assembled around an oil leak. :iceslolan
