Do you have to lube up the part the clutch after you're done setting the pulley on there? My fingers touched it quite a few times, I'm wondering if it's grinding because it's not lubed.
I guess I'll put the stock pulley back on and see if I screwed anything up.
The only thing I can say with a 100% confidence is that the grinding is most certainly coming from the very front of the supercharger pulley. Putting my ear anywhere else muffles the sound, putting my ear right in front of the pulley almost hurts it's so loud.
I've listened to youtube videos detailing bearing failure and none of them sound like the grinding I am hearing.
If I were to take the stock bearing out and swap it into the C3, how do I pop the bearing out? I heard you need a special tool, do I need to purchase this or would any auto shop have it?
Thanks again for following up.
process of elimination. if you put the oem pulley back on its the pulley. if the sound is still there you have another issue.
if it is the pulley the bearing would be the place to start. dont use the oem bearing, go to the mbworld c32 section theres a guy selling bearings for 25$ or hpautowerks has the replacement bearing for 50$
to reove the bearing remove the circlip and set the pulley in a press. press out the old bearing pres in the new. reinstall circlip and your done.
be careful with the pulley in the press its aluminium and can be damaged.
mist shops would charge about 25$ to press a bearing
no lube on the clutch or the pulley shaft. the pulley rides on the bearing
check the spring clips on the back of the pulley. they attach the magnetic plate to the pulley and see if any of the pop rivets that hold the clips on have been damaged.
with the pulley off you can spin the s/c shaft and listen for any noises. it should spin freely and quietly.
