The same has happened when the OEM pulley started to disintegrate. The rubber shock absorber started to fail and the crank pulley moved forward relative to the crankshaft.

Because of the misalignment the belt jumps a groove backward and hits the raised rib at the back of the pulley which cuts the rear rib off. These belts are strong and rigid sideways and do not take kindly to be out of alignment not like the old 'V' belts. The misalignment is also obvious on the smooth pulleys.

I erased a lot of my posts as people said they were to wordy, I was going to rewrite them but never bothered. I said f*** it and left them to figure it out.
