introduce
The 12V Fuel Shut Off Solenoid 3935649 is an important component for Cummins 5.9L, 8.3L, 6BT, and 6CT engines. Here
### Basic Information
- **Part Number**: 3935649 is the main part number, and it has some cross - reference numbers, including 4946639, 3965091, 3935289, etc. It's applicable to various vehicle brands and models equipped with Cummins engines, such as Ford, Freightliner, motorhomes, and marine applications.
- **Voltage**: It operates at 12V, which is consistent with the electrical system voltage of many vehicles and equipment using these Cummins engines.
### Function and Principle
- **Function**: The main function of this solenoid is to control the fuel supply to the engine. When the engine needs to be shut down, the solenoid receives a signal to cut off the fuel supply, ensuring that the engine stops running smoothly. It plays a crucial role in emergency shutdowns and normal shutdown procedures.
- **Principle**: Electromagnetism is the core principle. When the solenoid is energized, the electromagnetic force generated attracts the plunger, which in turn opens the fuel passage, allowing fuel to flow to the engine. When the power is cut off, the spring - loaded plunger returns to its original position under the action of the spring, blocking the fuel passage and stopping the fuel supply.
### Installation and Dimensions
- **Installation**: It is usually installed on the fuel injection pump of the engine. The specific installation location may vary depending on the engine model and the overall layout of the vehicle or equipment.
- **Dimensions**: The solenoid has a center - to - center bolt spacing of 3 inches, which is an important dimension for installation. It ensures a proper fit and connection with the mounting holes on the engine.
### Maintenance and Troubleshooting
- **Maintenance**: Regular inspection is necessary to check for any signs of leakage, loose connections, or damage to the solenoid. Keep the solenoid clean and free from dirt and debris to ensure its normal operation.
- **Troubleshooting**: If the engine fails to shut down properly or has fuel supply issues, the fuel shut - off solenoid could be the culprit. Common problems include a stuck plunger, a burnt - out coil, or a faulty electrical connection. Check the solenoid's resistance with a multimeter to see if the coil is intact. Also, inspect the wiring harness for any breaks or loose connections. If any problems are found, the solenoid should be replaced in a timely manner to ensure the normal operation of the engine.
