Cummins 3964622 is the 24 volt fuel shutdown solenoid with a mounting flange, moulded boot, plunger with rod end and a sealed three pin plug. It is used on Cummins 5.9 litre engines. This aftermarket version has the same mounting and electrical connector as the original, so it plugs in and bolts on where the old one came off.
Sold as one unit. Check the number on your old part, or in the parts manual for your machine, before ordering.

Engine will not start or will not stop
A failed fuel shutoff solenoid holds the fuel off (no start) or will not cut it (no stop). Check power at the plug first.
Engine cuts out
A weak pull-in or hold coil lets the solenoid drop out under vibration and the engine stalls.
Sticking plunger
Dirt and corrosion stop the plunger moving freely. Replacing the solenoid is quicker than freeing an old one.
Fleet spares
A spare solenoid on the van turns a no-start into a quick fix on site.

Yes, it is a direct replacement for the Cummins 3964622 with the same fitting.
There is no fixed interval. It is changed when it fails, and many fail from water in the plug or chafed wiring rather than wear.
A fault code for this circuit, readings that jump or stay fixed, or a part that does not respond with power at the plug.
A little dielectric grease keeps water out of the plug on machines that work outside. Make sure the terminals are clean and tight first.
Measure the coil resistance with a multimeter and check for supply voltage at the plug with the circuit on. An open coil reads infinite.
No. It is an aftermarket solenoid made to replace the Cummins 3964622. It is not made by the original manufacturer; the number only shows what it replaces.
