Fuel Shutdown Solenoid 3935456 3935457 for Cummins 5.9L 8.3L

3935456 and 3935457 SA-4762 Cummins Shutdown Solenoids

The SA-4762 family separates into 3935456 for 12V and 3935457 for 24V. Buyers should preserve that pairing and compare the mounting bracket, rod connection and connector because nearby SA-4763 references share market descriptions but remain a different order family.

Separating the SA-4762 Voltage Groups from Similar Cummins Solenoids

Use 3935456 or SA-4762-12 on a confirmed 12V system and 3935457 or SA-4762-24 on a confirmed 24V system. Do not replace the SA suffix with SA-4763 merely because the engine displacement overlaps.

Finding Hold-Circuit and Linkage Faults Before Replacing SA-4762

A solenoid that pulls but will not stay in the run position often has a hold-circuit fault, while a unit that stays energized yet cannot stop the engine may have a linkage problem. Observe the rod and measure voltage through both stages.

Information Needed for a Precise 3935456-3935457 Quote

Specify 3935456 12V or 3935457 24V, Cummins engine, SA-4762 label, bracket, rod, connector and quantity.

3935456-3935457 Fuel Shutoff Solenoid FAQ

Which SA-4762 number is the 12V version?

3935456 and SA-4762-12 identify the verified 12V group. Keep the voltage on the same purchase line because 3935457 is the neighboring 24V version and cannot be substituted electrically.

Which part number identifies the 24V SA-4762 solenoid?

3935457 and SA-4762-24 form the 24V group. Confirm the machine system and old label before ordering, especially when fleet records use only a broad Cummins 5.9L or 8.3L description.

Are SA-4762 and SA-4763 the same solenoid?

They should not be combined automatically. Catalogs often list both families near the same engine applications, yet the suffix is a configuration identifier. Preserve the full SA number and compare bracket, rod and connector details.

Why does the engine start and then stop when the rod initially moves?

The start circuit may energize the pull winding while the run circuit fails to maintain the hold winding. Check the relay, connector voltage drop and ground after the key leaves the start position.

What can make the engine keep running after the solenoid releases?

The pump lever may not reach the final stop position because of rod adjustment, bracket flex, a loose joint or restricted linkage. Confirm actual lever travel rather than judging shutdown from coil sound alone.

What details make an SA-4762 bulk quote reliable?

Send the complete voltage-specific OE, Cummins engine and serial, label photo, connector face, bracket-hole spacing, rod-end dimensions and quantity. Separate 12V and 24V demand into distinct RFQ rows.
