Depending on how much material is removed to get rid of the crack, just doing that should still provide plenty of material left to maintain the strength needed. Previous owner of this crank was of the 'grind the big gear' school of the day. I'll likely grind out the cracks and keep this bike for easier days when I'm not going to need to hammer on the cranks.
