I have a '90 SC that was having no troubles at all until about a month ago, it through the crankshaft pulley clean off. It sheared all 4 bolts off and tossed the pulley out of the car!
No one could decide why it would have done this, so i got a new pulley (the original got pretty torn up) and had it replaced. Of course, they had to drill out all 4 studs, but it was still pretty reasonable. Well, Thursday, it did it again! Now there is obviously something going on here. The current theory is that the harmonic balancer is of somehow and causing vibration to pass through to the pulley.
Does this seem like a reasonable theory? If so, how does this just suddenly happen?
What about just putting the pulley back on with Grade * bolts this time?
Thanks all!
