Fuel Shutdown Solenoid 3935649 3935650 for Cummins 6CT

3935649 and 3935650 SA-4764 Cummins 6CT Shutdown Solenoids

The SA-4764 family includes a 12V 3935649 version and a 24V 3935650 version. The 12V group also appears with Ford BG2X-9N392-AA and Volkswagen 2UO130764, but those references require the same connector, three-inch-style mounting and rod geometry.

SA-4764 Voltage, Bolt Spacing and Connector Checks

Choose the voltage-specific OE group first. For the 12V industrial style, confirm the published three-inch mounting arrangement and round-pin connector against the removed part; use dimensions rather than a visual estimate.

Using Terminal Function to Diagnose SA-4764 Pull-and-Hold Faults

Three-wire shutdown solenoids commonly use separate pull, hold and ground circuits. A wrong terminal assignment can damage the coil, while a missing hold feed produces a start-then-stop symptom even when the solenoid pulls normally during cranking.

Information Needed for a Precise 3935649-3935650 Quote

Provide the SA-4764 voltage group, Cummins/Ford/VW application, bolt spacing, connector, rod, engine serial and quantity.

3935649-3935650 Fuel Shutoff Solenoid FAQ

Which SA-4764 number is 12V?

3935649 and SA-4764-12 form the confirmed 12V group. Ford BG2X-9N392-AA and Volkswagen 2UO130764 appear as supporting references, but the old connector and mounting dimensions must agree.

Which SA-4764 number is 24V?

3935650 and SA-4764-24 identify the 24V group. Do not transfer Ford or Volkswagen 12V references onto the 24V order line without application-specific evidence.

Why is bolt spacing important for 3935649?

Industrial listings often describe a three-inch mounting arrangement, but bracket variants can exist. Measure the old holes center to center and record the bracket angle so a correct electrical unit is not paired with unusable hardware.

How are pull, hold and ground terminals verified?

Use the equipment wiring diagram or verified terminal markings, then test voltage during start and run commands. Wire colors are not a dependable universal standard after harness repairs or equipment conversions.

What causes an SA-4764 solenoid to overheat?

The high-current pull winding may remain energized, the rod may be blocked before reaching full travel, or the wrong voltage may be applied. Stop operation and diagnose the control sequence and linkage before installing another unit.

What information is needed for a cross-brand SA-4764 quote?

Send every old OE, system voltage, engine and equipment model, connector face, measured bolt spacing, rod-end view and quantity. For Ford or Volkswagen demand, add the vehicle or machine serial and installed pump photo.
