Product Overview
It is used in engine-control systems that need an electrical actuator to move a throttle or shutdown linkage. Research ties this format to multiple Genie boom/scissor platforms and several industrial engine packages, making the part number and linkage geometry essential fitment checks.
Applications can use Deutz, Perkins, Hatz or other engine packages depending on platform and serial range.
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: Applications can use Deutz, Perkins, Hatz or other engine packages depending on platform and serial range.
Technical Specifications
- Voltage: 12V DC
- Actuation: Pull / hold engine-control solenoid
Replaces / Reference Part Numbers

Common Replacement Reasons
- Solenoid will not pull in or hold when commanded
- 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?
Confirm Genie serial range, engine package, connector and plunger/linkage dimensions 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?
Failure may cause no throttle response, inability to remain running after start, or inability to shut down depending on how the linkage is configured.
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.
