Regrind Crank

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