Components of Cummins 4061693 Fuel Shutoff Valve Service Kit

The Cummins 4061693 Fuel Shutoff Valve Service Kit is a comprehensive assembly designed to facilitate the maintenance and repair of fuel shutoff valves. Each component within this kit plays a role in ensuring the valve operates correctly and efficiently. Below is a detailed look at the components and their functions:

• S257 Regular Hexagon Nut: This nut is used for securing various parts of the shutoff valve, ensuring that all components remain firmly in place during operation.

• 129768 Valve Spring: The valve spring is responsible for maintaining the proper tension within the valve mechanism. It ensures that the valve returns to its closed position after being actuated, which is important for the valve’s reliable operation.

• 129839 Shutoff Valve Shield: This shield protects the internal components of the shutoff valve from external contaminants and damage. It also helps in containing any potential leaks, thereby enhancing the valve’s durability and performance.

• 129888 Rectangular Ring Seal: The rectangular ring seal is vital for creating a tight seal within the valve, preventing fuel leakage. Its precise fit ensures that the valve maintains a secure seal under various operating conditions.

• 196057 Valve Disc: The valve disc is a key component that controls the flow of fuel through the valve. Its accurate positioning and movement are important for the valve’s function in regulating fuel delivery.

• 3056009 Actuator Disc: This disc works in conjunction with the solenoid to actuate the valve. It translates the electrical signal from the solenoid into mechanical movement, enabling the valve to open and close as required.

• 3098354 Solenoid: The solenoid is the electrical component that initiates the valve’s operation. It converts electrical energy into mechanical force, which is then used to move the actuator disc and control the valve’s position.

• 4088863 Actuator Housing: The actuator housing encases the solenoid and actuator disc, providing a protective environment for these critical components. It also helps in mounting the actuator to the valve assembly, ensuring stable and reliable operation.

Conclusion

The Cummins 4061693 Fuel Shutoff Valve Service Kit is a vital component for maintaining the efficiency and safety of heavy-duty truck engines. Its design, featuring high-quality materials and components, ensures reliable operation and easy maintenance. Regular maintenance and adherence to safety protocols are essential for maximizing the benefits of this Cummins part.
