A G-62 crank is in 3 pieces and it may not have been fully dialed in from the factory, I have seen that before. Dropping the engine just almost can't bend the crank as a rule they don't bend anyway, but a prop strike can twist one out of line and cause it to run out.
.003 will make a spinner wobble and a prop not track true, but the good news is they can be fixed W/O allot of hassle or money.
Another feature I like about the G-62 is that fact you can end for end the crankshaft if ever anything happens to the one end and go again as long as it is aligned .
