The Wacker Neuson 5200003477 Fan is a genuine OEM component designed for the G120 Generator series, including the Custom T4i, Cold Weather T4i, Standard T4i, and Hertz T4i configurations. As a factory-sourced part, the 5200003477 is manufactured to the same specifications as the original, ensuring a direct, hassle-free installation. This fan is the correct replacement for all G120 T4i-tier generator variants, giving operators confidence that they are sourcing the right part for their specific machine configuration.
Key Features
- Genuine OEM Airflow Geometry — Blade pitch and diameter match the original design exactly, maintaining the correct cooling airflow rate through the generator enclosure.
- Direct-Fit Replacement — Engineered to mount on the same shaft interface as the factory fan, allowing a straightforward swap without modification to mounting hardware or shrouding.
- Broad G120 T4i Coverage — Confirmed fitment across the G120 Custom T4i, Cold Weather T4i, Standard T4i, and Hertz T4i generator variants.
- Sustained Engine Temperature Control — A properly functioning fan prevents thermal buildup during extended operation; a worn or damaged fan can lead to overheating and unplanned shutdowns.
- Cold-Weather Variant Compatible — Verified for use in the G120 Cold Weather T4i configuration, where consistent cooling performance is critical even in low-ambient operating environments.
The cooling fan draws air through the engine and generator compartment to dissipate heat generated during power production. Without adequate airflow, engine and electrical component temperatures rise beyond safe operating limits, risking thermal damage to the alternator windings, engine block, and associated components. A failed or cracked fan blade disrupts the airflow balance, often triggering high-temperature shutdowns and reducing the overall service life of the generator.
