The Wacker Neuson is a genuine OEM 25.3 Sickle Fan G120 designed for the G100 and G120 series portable generators. As a direct-sourced Wacker Neuson replacement, this fan is engineered to the exact specifications of the original component, ensuring proper airflow and cooling performance across the full range of compatible G100 and G120 generator configurations — including skid-mounted, mobile, cold weather, and custom variants. With broad fitment coverage spanning standard, cold weather, and Tier 3 models, part number is the correct replacement for a wide variety of G-series generator builds. Confirming your machine number against the fitment list before ordering is always recommended to ensure an accurate match.
Key Features
- Genuine OEM Blade Profile: — Sickle-profile blade geometry is matched to the original fan design, maintaining correct airflow volume and directional discharge through the generator enclosure.
- Drops Into the Existing Fan Assembly: — Engineered to mount directly to the original hub and shaft configuration on G100 and G120 generators with no adaptation required.
- Wide G-Series Fitment: — Compatible with a broad range of G100 and G120 generator models, including skid-mounted, mobile, cold weather, and 600V switchable Tier 3 configurations.
- Protects Engine and Alternator from Thermal Overload: — A correctly functioning cooling fan maintains safe operating temperatures; a worn or damaged fan blade reduces airflow and risks heat-related damage to engine and electrical components.
- Built for Demanding Runtime Conditions: — Generator sets often run continuously under load; this OEM fan is built to withstand the rotational speeds and thermal cycling of sustained generator operation.
The cooling fan on a portable generator is responsible for drawing air through the engine compartment and over the alternator to dissipate heat generated during power production. On the G100 and G120 series, the sickle-profile fan blade is sized and shaped to move the correct volume of air at operating speed, keeping internal temperatures within safe limits. When a fan blade cracks, chips, or becomes imbalanced, airflow drops and vibration increases — both of which can accelerate wear on bearings, windings, and engine components. Replacing a damaged fan promptly with the correct OEM part, such as the Wacker Neuson 5000174555, restores proper thermal management and protects the broader investment in the machine.
