Replaced SC Clutch bearing last night ~ pics/video
Well I finally got around to replacing my noisy bearing in the SC Clutch. Thanks to TopGun32's post, I obtained the proper bearing needed. Last night I decided to take everything apart and tackle the job. It was very easy, and only took about an hour. Plus I got a chance to use my new shop press for the first time. I took some pictures, along with video of the before and after noise. You wont believe how noisy it was, the bearing was very bad when I took it out. The video is only 2mb, so its a quick download. Thanks to those who gave me advice on getting the job done.

Great Job, I am surprised that the new bearing makes no noise what so ever. That just shows me that mine is going bad even though I thought it was still good. After 40K mine makes some noise but I thought it was normal.
Looks like those 20 dollar bearings I bought will get changed every 30K miles.

Thanks very much for the post man! I'm gonna check mine out, since I already have a new bearing sitting in the garage in a box.
Three questions for you:
1. Is it absolutely necessary to have a press? I don't have one, and I guess I could go to a local shop and get them to remove the old bearing and press in the new one.
2. Did you just grip the pulley with a leather glove to undo that bolt in the front, or is there somewhere you can put a mandrel in to stop the rotation?
3. What did you clean the pulley with before you replaced it? It looks much better afterwards.
Regards,
Pete

2. I used air tools, and a slight grip. You could also lodge something between the clutch and the block.
3. I did clean the pulley. If I have something off the car already, it always gets cleaned up
I used Throttle Body Cleaner to get the oil and dirt off, and a small wire brush to get any of the hard crap off. It cleaned up real nice.

When I have more time, I am gonna pull all the pulleys off and check them. Reason being, the small idler pulley that came off was going bad as well.

great job!
its the best $18 i have spent in a long time...
to think that the dealer wanted $1k for a new s/c clutch is a crime!!!!!
i paid $70 to have mine installed, since I didn't have the press, but if you can borrow one its very easy.

This is what these forums are all about! If I recall correctly, the Benz dealers would tell you that your only option is to change out the whole supercharger. Ridiculous.
What's worse is that it gives the car a bad reputation to turn a $100 repair into a $3,000 repair.

Even if you factor in the cost of the press ($100 from Harbor Freight), the total cost was only $125. Obviously I now have a press for future jobs (control arm bushings waiting to go in lol). The press paid for itself very quickly.
By the way, after driving for two days, the car is definately quieter than before. It also feels like the SC is kicking in when it should all the time.

A lot 
110k
But I have to say, this car is so strong. Since I have bought it, I have taken care of many of the common issues. I think this engine has a lot left in it. I am the second owner. It was originally a lease from MB, with all service performed by them.
I have to admit though, as much as I love it, I am looking for an E55 right now. The prices are too good, and I could use more room for the family. More power never hurts either

exactly what I've been looking for...been lazy and haven't got around to search.
btw, notice there's a C ring type of clip on the old bearing, how did you remove that part?

I couldnt find a way to get it out and still be reusable. So I pryed it out. I am absolutey sure there is a way, I just didnt know at the time. I did not put it back in. I should probably see about sourcing another one just to be on the safe side. Although, the bearing is held in with a small disk and bolt, so I cant imagine its going anywhere. I am sure the retainer/snap ring is probably needed though.
