One New Aftermarket Replacement Hydraulic Pump Piston for Caterpillar (Cat) Equipment
This aftermarket replacement hydraulic pump piston (PISTON AS-PUMP) is a precision-fit internal component of the hydraulic piston pump assembly on Caterpillar skid steer loaders, compact track loaders, multi-terrain loaders, excavators, motor scrapers, and wheel loaders. The piston operates within the pump's rotating group, converting mechanical input into pressurized hydraulic flow to power the machine's hydraulic systems. Replacing a worn or damaged pump piston restores proper displacement and system pressure.
