CATERILARR-VALVE-EX

435-9545 is an exhaust valve for Caterpillar diesel engines, the component that opens each cycle to release combustion gas from the cylinder and must reseal against full compression pressure every time it closes. The valve face and stem tip are hardened to handle this repeated impact loading, but they're not immune to it — pitting on the face or stretch at the stem tip both point to a valve nearing the end of its service life.
