Product Overview
The solenoid electrically moves the fuel-control mechanism between run and stop. Failure can produce crank/no-start, intermittent shutdown or an engine that does not stop normally, depending on the mechanical position of the failed actuator.
Cummins identifies 3935649 primarily with Tier 2 5.9L B-series engines, and diesel-parts references list it for 6B applications. Match the part number, voltage and linkage style before ordering because similar shutoff solenoids are used on other Cummins engine families.
