Fuel Shut Off Solenoid 8190393 New Holland

The New Holland 8190393 Fuel Shut-Off Solenoid is a genuine OEM electro-mechanical control component designed to regulate fuel flow within diesel injection pump systems. Commonly referred to as a stop solenoid or fuel shut-off solenoid, it plays a critical role in engine starting and shutdown operations by electronically controlling fuel delivery to the injection pump. When the ignition is switched on, the solenoid receives a 12V electrical signal that retracts the internal plunger, allowing fuel to flow freely through the injection system. When power is removed, the internal spring automatically returns the plunger to its closed position, immediately interrupting fuel supply and safely shutting down the engine. This simple yet essential function helps ensure reliable engine control, improved operational safety, and protection against unintended engine run-on. Manufactured with a durable alloy steel housing and precision-engineered internal components, the 8190393 solenoid is designed to withstand vibration, temperature fluctuations, moisture, and demanding agricultural working environments. Its compact threaded design allows direct installation into compatible diesel injection pumps, providing dependable performance and long service life. As a genuine CNH Industrial replacement part, the 8190393 Fuel Shut-Off Solenoid ensures proper fitment, reliable fuel control, and consistent operation across a wide range of New Holland, Case IH, and Fiat agricultural machinery.
