Product Overview
It actuates the injection-pump/fuel-stop linkage from the equipment's key or controller. Because these engines are installed in many brands of compact equipment, the Mitsubishi engine and solenoid number are stronger identifiers than the host machine badge.
Machine wiring and linkage can vary even with the same engine family.
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: Machine wiring and linkage can vary even with the same engine family.
Technical Specifications
- Component: Engine stop / fuel shutoff solenoid
Replaces / Reference Part Numbers
MM432-30501, MM43230501
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?
Match MM432-30501, voltage, connector, mounting pattern and plunger travel with 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?
A sticky stop lever or low system voltage can prevent full travel.
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.
