One New Aftermarket Replacement Piston Crown for Caterpillar (Cat) Equipment
This aftermarket replacement piston crown fits a wide range of Caterpillar (Cat) engines used in motor graders, track-type tractors, wheel loaders, scrapers, and excavators. The piston crown forms the top of the piston assembly, sealing the combustion chamber and transferring combustion forces to the connecting rod during each power stroke. It is a precision engine component that must be replaced to OEM dimensional specifications to maintain proper compression and engine performance.
