I believe the internal mass some how wore out and or caused the failure, the internal bolts (3) were still there-bent. Iam going back to the stock crank and a 65 pulley, dont wanna have a third failure. Photos are for you to see the internal remains. Enjoy, Woody
Is some of that aluminum?
It looks a real mess, everything is destroyed.
Anyone with a similar part should pull it off or look at it carefully at least.
In my mind many of these aftermarket parts were made for a fast buck with little testing and sold with caveats that absolve the sellers of any future blame. The supercharger pulley fiascos were typical of this and my voiced concerns about these pulleys were poo pooed at the time, but the chickens came home to roost. The initial parts were poorly designed and made and I would not use any of them even now.
