Wacker Neuson 5000116350 Shutdown Solenoid

The Wacker Neuson Shutdown Solenoid is a genuine OEM component designed for G25, G20, and G12 series mobile generators and LT4Z, LTW4Z, and LTP4Z series light towers. As a direct factory replacement, the delivers the correct electrical specifications and mechanical fit required by these Wacker Neuson power units. This part covers an extensive range of G25 configurations including Standard, Custom, Cold Weather, Extended Run Tank, and T4i and T4F Tier-compliant variants. Confirm your model number before ordering to ensure a verified match.

Key Features

• Genuine OEM Electrical Specification — Sourced directly from Wacker Neuson, this solenoid meets the exact coil resistance and actuation voltage required for proper engine shutdown on G-series generators and LT-series light towers.
• Broad G25 Configuration Coverage — Fits Standard, Custom, Cold Weather, Extended Run Tank, T4i, T4F, and 600-Volt switchable variants across the G25 family, plus G20, G12, and multiple LT4Z, LTW4Z, and LTP4Z light tower models.
• Drop-In Replacement — Matches the OEM mounting points and wiring connector of the original solenoid, allowing straightforward installation without modification to the fuel system or wiring harness.
• Critical Fuel Shutoff Function — A properly functioning shutdown solenoid cuts fuel flow instantly on command; a failed or sticking solenoid can prevent the engine from stopping or cause unexpected shutdowns under load.
• Fuel System Safety Component — The shutdown solenoid is a primary safety control on these generators and light towers. Using a genuine OEM part ensures the shutoff response meets Wacker Neuson's original design intent for safe, controlled engine stops.

The shutdown solenoid is an electrically operated valve mounted on the fuel system — typically at the fuel injection pump or carburetor — that controls fuel flow to the engine. When the ignition is switched off or a fault condition is detected, the solenoid closes, cutting the fuel supply and bringing the engine to a controlled stop. If the solenoid fails in the open position, the engine may be difficult or impossible to shut down; if it fails in the closed position, the engine will not start or will stall unexpectedly. Replacing a worn or faulty solenoid with a correct OEM part restores predictable, safe engine shutdown behavior.
