The Wacker Neuson 5100012312 Fan is a genuine OEM component designed for the RD18-80 and RD18-100 series tandem rollers, including the RD18-80, RD18-80 US, RD18-100, RD18-100 US, RD18-100 C, and RD18-100 C US variants. Sourced directly from Wacker Neuson, this fan is manufactured to the same specifications as the original part installed at the factory. It covers an extensive range of RD18 configurations, making it the correct choice whether you are servicing a standard, SE, or C-model roller. Confirm your machine number against the fitment list to ensure a direct, bolt-in installation.
Key Features
- Genuine OEM Construction: — Blade pitch, diameter, and hub bore match the original design exactly, ensuring correct airflow volume through the cooling system of the RD18 series.
- Direct Bolt-In Installation: — Mounts to the original hub and fastener pattern with no rework or adaptation required to the surrounding shroud or drive assembly.
- Broad RD18 Series Coverage: — Fits RD18-80, RD18-80 US, RD18-100, RD18-100 US, RD18-100 C, and RD18-100 C US tandem rollers across multiple machine number configurations.
- Protects Engine from Overheating: — A correctly functioning fan maintains proper thermal management during sustained compaction passes; a worn or damaged fan blade disrupts airflow and risks engine overheat faults and shutdown.
- Long-Term Durability: — Built to withstand the vibration-intensive operating environment of a tandem asphalt roller, where fan imbalance or blade fatigue can accelerate bearing wear on adjacent components.
The fan on an RD18 tandem roller draws or forces air across the engine's cooling system to regulate operating temperature during continuous asphalt compaction work. Without adequate airflow, heat builds up rapidly in the engine, triggering thermal protection shutdowns and risking damage to internal components. A cracked, chipped, or out-of-balance fan blade reduces cooling efficiency and introduces vibration that can stress the fan hub and surrounding drive components, making timely replacement essential to keeping the roller running through long paving shifts.
