The fuel tank float assembly (860552037) is a genuine component designed for fuel level monitoring in XCMG XCT series truck cranes. It provides accurate fuel level indication to help operators track remaining fuel during crane operations.

1. Installation Location
This float is installed inside the fuel tank, typically through a mounting port on the top or side of the tank. The sensor unit extends into the tank with the float arm moving up and down according to fuel level. Proper installation ensures accurate reading of fuel volume.

2. Function
The float assembly converts fuel level into an electrical signal for the fuel gauge on the instrument panel. As the float rises or falls with fuel level, the sensor sends corresponding resistance or voltage signals to provide real-time fuel level readings. This helps operators plan refueling and avoid running out of fuel during work.

3. Maintenance and Service
If the fuel gauge reading becomes erratic or stays fixed, the float unit may need inspection or replacement. The sensor is not user-serviceable and should be replaced as a complete assembly (860552037) if found faulty. Always depressurize the fuel system and ensure the tank is at low fuel level before removal. When installing, use a new sealing ring to prevent fuel leakage.

4. Important Notes
Always verify the part number 860552037 matches the original component before installation. This sensor is specifically designed for XCMG XCT series cranes. Ensure the float arm moves freely without obstruction in the fuel tank before final installation.
