..Pully repairs itself...?

It had to do with the pulley itself being tweaked because a piece of the fan hit it when it broke. The shaft is as straight as it ever was and has no play. I just checked right now and the pulley is secure. it does still have a slight wobble though, 1/4" worth of wobble room at the most. Would it matter if I just run it like that? like I said its just the pulley itself, not the shaft.
