Cummins Solenoids — part numbers

61 numbers covering fuel shutoff solenoids, starter solenoids, actuator solenoids and the associated linkage and mounting hardware.

Small, inexpensive, and responsible for a disproportionate share of no-start callouts. A fuel shutoff solenoid that has failed will present exactly like a fuel supply problem or a control fault, and a great deal of diagnostic time gets spent elsewhere before someone checks it.

The ordering variables are voltage, the energise logic, and the linkage. Voltage is 12 V or 24 V and must match the system. Energise logic matters more than people expect: energised-to-run and energised-to-stop solenoids are physically interchangeable in many installations and functionally opposite, and fitting the wrong one produces an engine that either will not start or will not stop. The label on the existing unit, or the wiring at the panel, tells you which you have.

Linkage and plunger travel vary between applications even where the electrical specification matches. A photograph of the installed unit showing the linkage arrangement is worth more than a part number here, particularly on plant that has been refurbished with non-original parts.

On tier, good branded aftermarket solenoids are available and we quote them openly. This is a category where the price difference is small enough that the tier question rarely drives the decision — but the tier is stated on the line regardless, as it is everywhere else.

For a quotation: engine serial, system voltage, energise logic if known, and a photograph of the installation with the linkage visible.
