Fuel Shutdown Solenoid 504017345 SA-5018-24 for Woodward and Syncro-Start 1751ES shutdown systems

504017345 Configuration-Specific Diesel Shutdown Solenoid

504017345 is a coded shutdown solenoid for Woodward and Syncro-Start 1751ES shutdown systems. The full number is functional data: voltage, mounting, plunger, grounding, terminals, boot and spring can change with individual suffix characters. Keep the complete code intact on the RFQ, purchase order and carton label.

504017345 Product Information

Complete-Code Approval for 504017345

Retain every character in 1751ES-24E7UC91S5CC57. Its voltage and configuration suffix identify a specific electrical and mechanical build; compare the complete old label, mounting, terminals, output end and working travel before approval.

Electrical and Mechanical Checks for 504017345

Check the electrical command, component response and final mechanical movement as separate observations. This prevents a wiring, control-module or linkage fault from being mistaken for a failed replacement part.

504017345 Replacement Approval Checklist

Release the order only after electrical, mechanical and application evidence agrees with the removed assembly.

504017345 Technical FAQ

What voltage must be confirmed for 504017345?

504017345 is covered here as 24V. Confirm the charging system and old label, then measure voltage at the connector during the start or stop command. A battery description alone is insufficient when converters, relays or earlier harness repairs may have changed the actual supply.

What should be checked on Woodward and Syncro-Start 1751ES shutdown systems before ordering 504017345?

Use 504017345 / SA-5018-24 / 1751ES-24E7UC91S5CC57 as the first control, then compare the old label, voltage, connector face, mounting-hole centers, output end and operating direction. Record the engine or machine model and serial number, but do not use the model name alone because production changes can introduce another shutdown arrangement.

Why must the complete 504017345 suffix be retained?

The suffix can encode mounting, plunger thread, grounding, terminals, boot and spring family. Shortening the code can merge non-interchangeable parts in purchasing records. Photograph every readable character and retain the full string on the RFQ, order and carton label.

Can another solenoid with the same voltage replace 504017345?

Voltage is only one control point. Mounting style, plunger thread, energized direction, terminal arrangement, grounding, boot clearance and required force must also agree. Compare the complete code and removed-part dimensions instead of selecting by coil voltage alone.

What causes a start-then-stop fault on this coded solenoid?

The pull circuit may move the plunger during cranking while the hold circuit fails after the start signal is released. Measure hold-terminal voltage under load, inspect relay logic and connector resistance, and confirm the plunger reaches full travel.

What should be compared with the removed 504017345 assembly?

Compare the full label, voltage, connector face, terminal count, mounting-hole centers, body orientation, output end, resting length and working travel. Include one wider installed photo showing pump, lever or surrounding clearance because close product images can hide the geometry that decides fitment.

How can repeat electrical or coil damage be prevented?

Correct the original failure cause before installation. Check supply voltage, pull/hold timing, linkage resistance, mechanical stops, terminal tightness, heat and moisture exposure. A new unit can fail quickly when the high-current stage remains energized or the output cannot complete its designed stroke.
