5i-7518 24V Shutoff Solenoid Valve — Cat 3064 3066

This is a 24V shutoff solenoid valve, an essential electrical component that controls the fuel supply to the engine based on electrical signals. It acts as an on/off switch for fuel flow, ensuring the engine stops cleanly when the ignition is turned off and preventing unintended starts, unlike a faulty solenoid that may stick open or closed. Operators may experience the engine failing to shut off completely or difficulty starting the engine when this valve malfunctions.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

A failing shutoff solenoid may cause the engine to continue running after the key is turned off, or it may prevent the engine from starting altogether. If the solenoid fails to close properly, it can lead to fuel system issues and potential stalling. The worst-case scenario is the inability to shut down the engine in an emergency situation.

Installation Tip

Ensure the electrical connector is clean and free of corrosion before reconnecting the new solenoid. Avoid using excessive force when threading the solenoid into its housing, as this can damage the valve seat.

Service Note

Inspect the fuel lines and associated electrical wiring for any signs of damage or leaks when replacing the shutoff solenoid valve.
