You can't quite see the other side in this picture but this is what an overloaded
two rotor engine psru gear looks like when it fails. Teeth fail on both sides
of the gear because the two rotor fires twice per rev. Of course if you persist 
in running the engine I think the gear teeth will be cleaned off completely. The failure 
you describe Tracy is very mysterious indeed. Perhaps the sun gear was not concentric
with the input shaft.
