When an EX450-class excavator starts showing uneven hydraulic response, the real issue is often hidden inside the pump system—loss of pressure stability, weak multi-function coordination, and reduced digging efficiency under load. The 4352970 hydraulic piston pump assembly is designed to correct this imbalance by restoring controlled hydraulic output and consistent energy delivery across the system.
