4664585 Original Excavator Fuel Tank Float for Hitachi ZX470-6

Part number 4664585 is the original fuel tank level sensor, commonly known as the "tank float," provided by Hitachi for the ZX470-6 large hydraulic excavator. The universal model of this component mainly covers ZX470-6 and other large models on the same platform, used for precise measurement and transmission of real-time fuel level signals in the fuel tank to the cab instrument. As an original sensing component, its float stroke, resistance (or frequency) output characteristics, installation flange size, and fuel tank structure and dashboard are fully matched

Installation and Calibration: 1 Safety and cleanliness: Ensure that the engine is turned off and there are no open flames around before installation. Thoroughly clean the flange surface installed on the fuel tank to prevent debris from falling into the tank. 2. Alignment installation: Place the float assembly (4664585) vertically and aligned into the fuel tank installation port, ensuring that the float and lever move freely without any interference. 3. Tightening and sealing: Install the flange gasket and evenly tighten the fixing bolts in diagonal order (usually with a torque of 10-15 N · m). 4. Wiring test: Connect the wire connectors, start the power supply (without starting the engine), and observe the position of the oil gauge pointer on the dashboard. You can try manually moving the float up and down slowly, and the oil gauge indicator should change steadily accordingly
