Product Overview
It provides the electrical pull/hold action used to move the engine's fuel-stop linkage. A failed unit can leave the engine unable to start, unable to shut down from the key, or require manual movement of the stop lever.
Designed around the SA-3766T/1751-24E mounting and linkage format rather than a universal solenoid.
Key Features & Performance
- Controlled engine actuation: Provides the electrical movement needed for the listed fuel-stop, shutdown or throttle linkage.
- Part-number driven fitment: Solenoids that look similar can differ in voltage, stroke, connector and hold circuit, so the exact reference matters.
- Troubleshooting-friendly replacement: Power supply, grounds and free linkage movement should be verified so an electrical or mechanical fault is not mistaken for a failed actuator.
- Product-specific note: Designed around the SA-3766T/1751-24E mounting and linkage format rather than a universal solenoid.
Technical Specifications
- Voltage: 24V DC

Common Replacement Reasons

- Engine will not shut down normally or will not remain running because the stop linkage is not being actuated
- Coil/connector failure after wiring, voltage and linkage movement have been verified
Frequently Asked Questions
How do I confirm this is the correct part?
Verify 24V system voltage, connector/lead arrangement, mounting pattern and linkage stroke against the original.
Is this an OEM part?
Unless the listing is explicitly identified as genuine/OEM in the product data, treat it as a replacement component. Use the verified reference numbers, equipment application and physical configuration above to match your original part.
What should I check before installation?
Check plunger travel and linkage position if the engine stop system binds even with a working solenoid.
Fitment note: Equipment manufacturers may use different components within the same model family based on engine, serial number or production date. Confirm the original part number and machine/engine details before ordering.
