Yesterday one of my drive belts got thrown and shredded, plus the crankshaft pulley is wobbling. I heard the racket and stopped to the car the first timeimmediately. Replaced with a spare I carry then drove home a short distance. I did not know the pulley was damaged until I inspected it on the drive at home. I am aware of the design of the pulley, with rubber being used as a vibration damper - the rubber is the weakness. I have checked on the net for a replacement. Eurocarpart sell it for £150.
