<VV> Bearing WAS Broken Crank! Questions

[kenpepke at juno.com]

The bearing at the flywheel end has been discussed in the past on this venue.  Engineers developed a special bearing in which the center was slightly offset.  This was to remove a 'bump' sound at idle.  Replacement bearings did not have this offset.  Crankshafts have been known to fracture even with this special bearing.

What are the crankshaft numbers and the engine numbers please?
Timothy Shortle in Durango Colorado

The engine number is T0625RH and the crank is marked 8409.  According to the Junkyard 
Primer this is a long stroke crank.

I haven't gotten down to the bearings yet, but there were no loose bolts on the 
converter, no abnormal looking wear on the parts, and no unusual vibrations in the car 
before this happened.  I am not very experienced with Corvair engines though and I may be 
missing something.

Good question about that last bearing - if the engine has been rebuilt and the wrong one 
placed there then it could be the cause.  Will check that next.

Thanks for the questions and input.
