The Genie 77402GT is a genuine OEM Throttle Actuator DSL Solenoid built for Genie S series telescopic and Z series articulating boom lifts. As a direct OEM replacement, part number 77402GT is manufactured to the same specification as the original, ensuring a correct, trouble-free installation. This solenoid fits a range of models including the S-65 XC, Z-60/34, Z-51/30J, Z-62/40, Z-45 XC, Z-34/22 IC, Z-45/25 IC, Z-34 IC, and Z-80/60. Cross-reference 77402GT against your machine's parts manual to confirm this is the correct component for your unit before ordering.
Key Features
- Genuine OEM Quality — Built to Genie's original specification, delivering the correct electrical actuation characteristics for DSL-powered boom lift applications.
- Direct OEM Replacement — Designed to drop into the original mounting position without modification, restoring the throttle actuator circuit to proper operation.
- Broad Boom Lift Fitment — Compatible with multiple Genie S series telescopic and Z series articulating boom lifts, including the S-65 XC, Z-62/40, Z-80/60, and additional models in the Z series lineup.
- Restored Throttle Control — A functioning throttle actuator solenoid allows the engine to respond correctly to operator inputs; a failed solenoid can result in loss of throttle control and prevent the machine from reaching operating speed.
- Operational Safety — Proper throttle actuation is essential for safe boom lift operation; using a verified OEM solenoid ensures the component meets the original performance criteria for the machine's engine control system.
A throttle actuator solenoid controls engine throttle position by converting an electrical signal from the machine's control system into mechanical movement. When the operator calls for speed or the machine's logic demands a change in engine output, the solenoid actuates to open or close the throttle accordingly. When this component fails or sticks, the engine may idle roughly, fail to reach full power, or become unresponsive to throttle commands — any of which can affect the machine's ability to perform lift and drive functions safely.
