Hitachi excavator angle sensor 4716888 hydraulic pump angle sensor

4716888 is a Hitachi excavator hydraulic pump angle sensor used to detect the angle position of the hydraulic pump's inclined plate or related mechanisms, feedback the pump's displacement status to the controller, and achieve precise flow and pressure control. Common Symptoms of Malfunctions: 1. Weak hydraulic action or abnormal speed 2. Pump displacement control failure, power matching mismatch 3. Abnormal increase in engine load or fuel consumption 4. Relevant hydraulic control fault codes appear 5. Abnormal response after switching working modes 6. Unstable hydraulic system pressure and damaged angle sensors can cause inaccurate pump control, affecting overall operational efficiency and stability. It is recommended to replace them in a timely manner.
