139-8247 Shutoff Solenoid — Cat

This shutoff solenoid is an essential engine control component responsible for stopping fuel flow to the engine when activated. Manufactured to meet stringent OEM standards, it ensures reliable engine shutdown and prevents over-speeding, unlike a worn solenoid that may stick open or closed. Operators may observe the engine failing to shut down when the key is turned off, or difficulty starting the engine if the solenoid is partially stuck.

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

The most common symptom is the engine failing to shut down when the ignition key is turned to the off position. In some cases, a malfunctioning solenoid may also cause intermittent starting issues or cause the engine to run erratically. Failure to shut down properly can pose a safety risk during operation.

Installation Tip

Before installing, ensure the solenoid plunger moves freely by applying a small amount of voltage to test its actuation. Do not force the solenoid into its mounting position; ensure the threads are clean and properly aligned to prevent cross-threading.

Service Note

Inspect the fuel lines and filter for any signs of blockage or damage when replacing the shutoff solenoid.
