Anybody knows the maximum and the minimum displacement (cc/revolution) of the HPV160 Komatsu hydraulic pump for the PC300 dash 5
My old service manual shows 250 liters per minute per pump but that is only a theoretical number. From experience it is just over 40 gallons a minute per pump with minimum pressure at full tilt and minimum output is about 12 gallons a minute per pump. The system is load sensing so depending on the tune up of the pump and the settings of the machine it will vary depending on the load put against it.
