Noise from supercharger

One afternoon, I started my car and heard this noise coming from the engine compartment.



It disappeared when I reved the motor. The next day, it did the same thing, but the noise didn't end.

I took it to the dealership and after a few attempts, they were able to isolate it to the supercharger. The dealership is currently replacing the part. They said it sounded like a possible bearing going out.

I wanted to post this in case anybody else experiences this.

sounds like one of the front rotor bearings which I hear have been known to run dry.

Is there a good way to prevent this from happening with the new unit?

The bearings are sealed so really nothing to do. I don't know if Eaton changed something in the manufacturing but the problem is just now starting to come up from time to time. New one should be fine.

^^this is false.

The front rotor bearings are open needle bearings.

If you can get it warrantied do it. If not contact me and I'll go through how to repair it with you.

So will the dealer R&R the blower? Any chance of them replacing the bearing only? Thanks for the answer, I had asked the question in the old thread and you just provided my answer.

Same noise I had. They'll just replace it under warranty. There really have been too many of these failed superchargers.

I know you know the blowers better than I do so I'll take your word for it. So do you recommend any kind of regular maintenance for those front bearings? if so at what interval?

Noise

I had a very similar noise and I pulled the main belt cleaned with a brush on the bottom, removed the Idler pulley and worked it as it seemed stiff. Put everything back on and it has not come back. I even bought a Metco Idler pulley but I havent put it on because things remain quiet.

I didn't touch my wife's blower for 35000 miles.. put a pully on it and it did it immediately. . I started learning about it then. If the snout is installed properly I don't know how long a good interval is yet. If your turning the blower over 20000 RPM I would think every 10 thousand miles for a do it yourselfer but that strictly a percussion. The needle bearings are easy to grease and the entire process of taking the blower apart isn't hard. BUT that being said it really shouldn't ever need to be done on a stock blower running around stock speed.

So how much faster would the blower be spinning with a 10% O/D pulley on the crank?

10%OD....equates to approx. 18,600 @ 6500 engine RPM

...there are many threads on the issue of the S/C coupler noise. It's normal for the Eaton design. Use the search engine to read extensively about it.
