Had an interesting talk with Ken Kalina of Kalina Machine.... He was curious why I didn't want to turn my crank. I replied that I heard that the cranks are hardened and that people have had problems with them after they turn them. He claims that "to his knowledge" there were only a few cranks ever produced that were hardened, and the mitu's weren't on the list.

Are our cranks hardened or not? If so, where is the proof of this? I've got 3 blocks now that all need cranks turned, no reason to thow them out if they can still be used!

My understanding is that the cranks have been nitrided. You can turn them and the will work. They will not have the nitride hardening anymore though.

Exactly, You can get them re nitrided though, still not a good idea.
