Hmmm, soft crank journal? Were the bearings worn at all?
Oh the pictures don't work, server down or somthing.
It can be normal for cast iron crankshafts for gas engines not to have hardened journals. With proper lubrication there is no journal to bearing contact, so hardness is not a factor. If it is something that is heavily loaded and there is a chance that the hydrodynamic wedge may break down then there is a chance and that is why most diesel and aircraft journals will be hardened, but still the softer bearing material is what wears first, not a crank journal.
Who originally put it together?
