Solenoid 437-2617/HWS3072829 is a fuel shutoff or stop solenoid: on the controller signal it cuts the diesel supply and stops the engine.
Its two failure modes give opposite symptoms: if it does not open, the engine cranks and will not fire; if it does not close, the engine will not stop on the key and the valve has to be closed by hand. Both are easily mistaken for a pump fault.

- 24 VDC
How to verify before ordering
- Match reference, coil voltage (12 V or 24 V) and mounting type (threaded or flange).
- Check whether the solenoid is two- or three-wire: three-wire units carry a hold-in coil and will not accept a two-wire replacement.
- Inspect plunger and return spring in the shutoff mechanism: a bent plunger destroys a new solenoid within a few cycles.
- Declared make or line: PERKINS. If your equipment carries another make, the part may not be equivalent.
Frequently asked questions
The engine will not stop on the key. Is it the solenoid?
Often, but confirm the signal first: if no voltage reaches the connector when you switch off, the fault is in the controller or the wiring, not the solenoid.
Can I run with the solenoid bridged?
Only as a test and for minutes: bridged, the engine cannot be stopped on the key. Never leave it that way on a set in service.
