155-4653 Fuel Shutoff Solenoid — Cat 3306

This fuel shutoff solenoid is an electrically operated valve that controls the flow of fuel to the engine, essential for starting, stopping, and preventing unintended operation. It ensures positive fuel cutoff, unlike a faulty solenoid that may stick open or closed, preventing proper engine management. Operators might experience difficulty starting the engine, stalling, or the engine running continuously when the stop switch is activated if this solenoid fails.

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 common symptom is the inability to shut off the engine using the normal stop control. If the solenoid fails to open, the engine may not start or run at all. If it fails to close, the engine could continue to run after the stop switch is activated, posing an operational risk.

Installation Tip

Ensure the electrical connector is clean and properly seated to prevent intermittent operation or failure. Do not apply excessive force when threading the solenoid into the fuel system housing, as this can damage the threads.

Service Note

Inspect the fuel filter and fuel lines for any restrictions or contamination when replacing the fuel shutoff solenoid.
