Certainly, the description of this particular failure is missing a number of details. But there has been no mention of the balancing disk coming off. There is no indication that the crankshaft bolt failed. So the most probable scenario is that the bolts that attach the damper and pulley sheared, leaving the balancing disk in place. In this situation, damage to the crankshaft is improbable.

this is good. i was apparently a bit vague about how it all attaches. sorry if i caused or added to any angst.
i hope the big bolt is still attached.
