I have been hearing a noise lately and when I changed the IC pump tonight (thanks Rob!) I also took a video. It goes away when the SC clutch engages and comes back every time as soon as the SC clutch disengages. This is the 62mm Karmen pulley. Will have to take the belt off this weekend to check it out some more. What do you think it is?

Could someone post a quick video of their SC clutch as the car is turned off?

 

SC pulley bearing, the outer bearing does not rotate against the inner race when the SC engages but the two parts do turn against one another when you turn it by hand with the engine stationary or the car is idling as the rotors free wheel then.

 

bearing on the s/c could be showing some issues. Not the pulley.

 

Pulley bearing. Mine was starting to get that way.

 

Hmm... Strike that.. Not sure.

 

Bad bearing in the supercharger pulley. Don't run it that way. Remove the supercharger pulley and get a new bearing installed.

 

thank you gentlemen!

 

OEM pulley back on, Eurocharged V2 software to remove tune and flash OEM pulley tune, no noise.


The 62mm pulley bearing seams fine and has no resistance after I got it off but since the OEM one fixed the noise problem, it has to be the bearing as you guys stated.


I was able to leave most Latemodel21's pulleys with the same OEM belt by just removing pulley number 1 and it's bracket.

Anyone recommend a bearing press?

 

Here is something that I use. 6 Ton A-Frame Bench Shop Press
With a coupon, you can have it for even less than that.
BTW, what color seal was on original bearing in this Karmen pulley? Was it green?

 

I've replaced a few bearing on the V8 superchargers and it was very easy without a press. I've not tried this method with the V6 pulleys though, but the principles are the same.

 

The bearing seal is brown on my bearing. it is made in china and is a C&G brand or something.


Thanks for the video Grip, that really was impressive how easy his bearing dropped in. He was entertaining as well. I think I would use a different removal technique though, I don't like the idea of the pressure on the shoulder of the pulley where the rivets are.

 

used grips video link method to remove but used my work bench with a 1 7/8" hole cut through it that fit the bearing nicely. The hardest part was removing the spiroloc retaining ring.

the bearing trick does work on this pulley and bearing! Saweet no press needed. I heated the pulley at 200 degrees and froze the bearing both for 2 hours, now it's fan cooling for 2 hours. Jerry e-mailed me a tune that will go back on.

Congrats!

 

Nice! Glad it worked out for you.

 

ahhhhhhh! Thanks for all the help!
