Fuel Shutdown Solenoid 3990772 3990773 for Cummins 6CT

3990772 12V and 3990773 24V Cummins 6CT Shutdown Solenoids

3990772 and 3990773 form a clear voltage pair for Cummins 6C and 6CT 8.3L fuel shutdown service. The supporting Woodward family is SA-4932, not SA-4293, so the purchase record should preserve the exact reference and avoid a common transcription error.

Correct SA-4932 Mapping for 3990772 and 3990773

Use 3990772 with SA-4932-12 for 12V and 3990773 with SA-4932-24 for 24V. Then compare bracket angle, output joint, connector body and full linkage travel with the removed assembly.

Preventing SA-4932 and SA-4293 Purchasing Mix-Ups

SA-4932 and SA-4293 differ by one digit yet belong to separate reference groups. A buyer should cross-check the Cummins OE, voltage suffix and old label before the line enters a purchase order, because a spreadsheet typo can produce a physically and electrically wrong solenoid.

Information Needed for a Precise 3990772-3990773 Quote

Provide 3990772 12V or 3990773 24V, Cummins 6C/6CT data, old label, bracket and connector photos and quantity.

3990772-3990773 Fuel Shutoff Solenoid FAQ

Which Woodward number belongs with 3990772?

3990772 belongs with SA-4932-12 in the confirmed 12V group. SA-4293 belongs to another family and should be treated as an error if it appears beside 3990772 in a quote or spreadsheet.

Which reference identifies the 24V version?

3990773 and SA-4932-24 identify the confirmed 24V version. Write both the Cummins OE and 24V on the purchase line so the suffix is not lost during warehouse or supplier processing.

Why is a one-digit SA number error important?

A near-matching number can point to another bracket, linkage or voltage family. Cross-checking the old label and Cummins OE before order release prevents a small data-entry mistake from becoming a field fitment problem.

Can the Cummins 6CT 8.3L engine name alone select 3990772 or 3990773?

No. The engine name supports application, while system voltage chooses between the two references. The bracket, output joint, connector and available travel should also match the removed fuel shutdown solenoid.

What should be checked if the engine starts but the solenoid releases?

Inspect the hold circuit, relay and connector voltage after cranking. A healthy pull action followed by immediate release often points to loss of hold power rather than incorrect bracket geometry.

What should a distributor include in a mixed-voltage RFQ?

Use separate 12V and 24V lines with 3990772/SA-4932-12 and 3990773/SA-4932-24 respectively. Add quantity, connector photos, bracket measurements and engine information for each group.
