Where is the fuel shutoff solenoid?
The stop solenoid is usually located at the entrance to the fuel injection pump or in the fuel line before the fuel injection pump. At a state of rest, the solenoid will have no power and need to be energised to allow the engine to run.
How do I know if my solenoid is bad?
If the clicking you are hearing is quiet or repetitive, it may be that your solenoid is not strong enough or does not have enough power from the battery. If you hear no sound at all or the car doesn’t start, this could be a sign of a faulty solenoid.
How does a 3 wire stop solenoid work?
The externally switched (3-wire) solenoid is used in applications where an operator/driver manually turns a key switch that temporarily energizes the pull coil to pull in the plunger.
How does fuel stop solenoid work?
A Stop solenoid is used to cut the fuel supply to the engine when the ignition is switched off. Stop solenoid fits into the diesel distribution pump and can be a cause for diesel systems to fail. When the solenoid is turned on the plunger pulls the valve which allows fuel to pass through.
Where is the cat 3116 fuel shutdown solenoid located?
It is located on the Governor/pump assembly [threaded in] with two wires controlling the electro-magnetic on/off function.
Why are solenoids a good part of a caterpillar?
Offering long service and value, they generate an essentially uniform magnetic field when currents run through it and convert electric current to mechanical action, providing a simple means to generate a strong magnetic field. They make a great fit for applications that require immediate action.
Can a fuel shutdown solenoid be replaced?
I just replaced a fuel shutdown solenoid that got so hot it startd to seep engine oil, this is rare. The Cat 3116 tune-up kit comes with a special tool to remove the solenoid [Tool #9U5120] the complete tune-up kit # 128-8822.
How does a solenoid work on a diesel engine?
Fuel shut-off solenoids often are used on diesel engines to interrupt fuel flow from the injection fuel pump when the ignition is switched off. On start-up of the engine, a solenoid pull-in coil must be temporarily activated to turn on the solenoid.
