Interesting engine problem

Hey guys, a 660 motor that blew up is currently being rebuilt but I've hit a roadblock. It seems the ring that is mounted on the crank for the counterbalancer drive gear has rotated. I lined everything up twice and the counterbalancer is hitting the crank when I turn the engine over. There is the hole in the ring that you line the gear up with, and it seems to be located about 1 o'clock from TDC. My guess is it should be aligned with TDC. Am I correct?
