For those who have had extreme over rev (IE 11,000 rpms during a missed shift etc.) it will often show up in a bent crank stub.

I just checked the runout of the alternator rotor on my H1A using feeler gauges (measuring the stator gap).

.012in wobble!

I'll be interested in having a good look at the radius under the alt rotor when I take it apart! :?

Sorry to hear this news
No need to dis-assemble though
Bent side up
Big hammer in hand....

Did it at least sound incredible at 2 million RPM?
