Hi David,
It is difficult to judge the surface of the tracta parts in the photo, but when metal transference happened, a pit and a pimple, if it was only a small area, the surface could be stoned smooth and clearance checked and re-used. Our inspection standards (REME) stated that a certain percentage of area could be affected but still used as any small pockets/pits retained oil.
