The GYT cylinder has been re-habbed with a Nikasil job done by Millennium Technologies. The photo doesn't do the quality of the work justice.
When I moved north, I lost the abillity to drive 15 minutes to one of the best machinists I've ever known. Road trip time!! Greg rebuilt the crank and repaired the buggered up mag end of the crank. Someone had beaten the carp out of the crank trying to get it out of the cases(??). I tried to file it back to a round end and chased the threads. All I managed to do was make the threads thinner and weaker. Greg laid a weld over the damaged threads and cut new ones.
The rod that was on the crank was possibly the original. I feel a lot better having the slotted 431 rod in the motor.
