One New Aftermarket Replacement Piston for Caterpillar (Cat) Excavators
This aftermarket replacement piston is a direct substitute for Caterpillar OEM part number 1438023. The piston is an internal engine component that converts combustion pressure into mechanical motion, and is subject to extreme heat and mechanical stress in heavy-duty diesel excavator engines. Replace worn or damaged pistons during engine overhauls or when symptoms such as loss of power, excessive oil consumption, or blue exhaust smoke are present.
