YNF17203 Piston HPV0102 Hydraulic Pump Connecting Rod Piston for Excavator Main Pump

The YNF17203 connecting rod piston, engineered for the HPV0102 hydraulic pump, is a vital component in the pump’s rotating group. This piston converts hydraulic pressure into mechanical movement, enabling stable pressure delivery and smooth oil flow throughout the excavator’s hydraulic system. When a piston becomes worn, scratched, or fatigued, the pump may experience reduced pressure, overheating, internal leakage, and significant performance loss.

Manufactured from heat-treated alloy steel and finished with precision CNC grinding, the YNF17203 piston provides excellent dimensional accuracy, smooth sliding performance, and superior resistance to long-term high-pressure operation. Its reinforced design ensures dependable hydraulic output even in tough construction and mining environments.

This piston is widely preferred by hydraulic pump rebuilders, aftermarket distributors, and machinery maintenance workshops. Replacing worn pistons improves pump efficiency, enhances machine responsiveness, and reduces downtime during critical excavation projects.
