Crankshaft regrinding
The crankshaft undergoes high loading due to the fact that it transforms the linear loading of the pistons into a usable rotational motion.
In time it will wear. Rather than replace this relatively expensive part, the surfaces can be reground.
This regrinding is a specialized process as the grinding wheel needs to travel horizontally - while the crank rotates.
