Helping a friend out at a museum. The 725 had a bad rod knock and #5 bearing is trashed with material transfer to the con rod ends. The crank rod journal is ok, but needs to be polished. We are not going to take it apart further and I am trying to figure out the best course of action. I think it is going to be just get a new bearing and reassemble. The rod journal is at 2.055" (measured with a cheaper digital caliper).
What would you guys do? What size bearing would you recommend?
Thank you
Mark
