This belt to shim contact caused them to spin on the shaft, as the belt tension was being dictated by the contact with the shims instead of the contact with the pulley halves. Very, very similar sound as you are displaying!

From your picture/videos, it appears that your belt is indeed very deep in the alt.

Thanks Mark. I'll take a look at that. Just curious, did your bug make the noise only when it got hot?
