The setup has a hub bolted to the crankshaft with a large very tight bolt. The "damper" sits on the hub and then the pulley sits over it with the six allen bolts holding both to the hub. I dont see any way that the damper would fail and end up out of round. I'm suspicious that the large bolt that holds the hub has worked loose and the whole shebang is wobbling and likely damaging the crankshaft at the same time. FWIW if you have to remove that large bolt for the hub you hold the engine at the flywheel. There is a special tool for the job but you can get by without it. Just be warned that large bolt should be tightened to 250ft/lbs + 90 degrees....=really friggen tight.

Thanks, so much for your reply. It was difficult for me to assess this correctly, but see if you can follow me. I took off the six allen bolts... took off the pulley. The big bolt is tight. However, a metal plate separated from the other (i guess damper plate) plate. I might need a puller to get the other plate off...or else i need some wd-40 or some-such. I think the separation of the plates caused some sort of wobble. I don't think the crankshaft is damaged. I can purchase the part that will secure the flywheel...but don't really think I need it... I just have to get the damper plate off. I am trying to secure another harmonic balancer damper. I don't understand the design. Why would one plate be bonded to another in some manner.... seems like a metal disc is bonded to a rubber coated metal plate to form the harmonic balancer. See if this makes sense. A colleague told me his plates separated on his car, causing the same symptoms. I'll keep everyone posted. Everyone says this failure is uncommon.
