The remedy for a worn pivot hole, bushing provides it with a new bearing surface. The worn hole is opened further to round it up and to bring it to its original center. The new brass bush has a fine hole drilled in its center and is then turned to fit tightly into the new hole in the clock plate, and adjusted for length. Finally the bush is hammered or pressed into the hole and the new pivot hole in its center is broached out and burnished to suit its pivot. An oil sink or reservoir is cut on the outside of the new bush. Rebushing of a worn hole previously bused is more simple, for the worn bush can easily be replaced with a new one, and some clocks have removable bushes fitted at the time of manufacture.
