The Wacker Neuson 5100012187 Fan is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers. Sourced directly from Wacker Neuson, this fan is an exact match to the original part installed at the factory, ensuring proper airflow and thermal management within the machine. It is compatible across the full RD40-130 and RD45-140 model families, including open-canopy, closed-canopy, and US-market variants. When your existing fan shows signs of wear, damage, or reduced performance, replacing it with part number 5100012187 restores the cooling system to proper operating condition.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original blade geometry and material specifications, delivering the correct airflow volume and direction for the RD-series cooling system.
- Direct Drop-In Replacement: — Engineered to match the original mounting interface, so installation aligns with existing hardware and drive components without modification.
- Broad RD-Series Compatibility: — Fits the full RD40-130 and RD45-140 tandem roller families, including open-canopy, closed-canopy, and US-market configurations across multiple build series.
- Sustained Engine Temperature Control: — A properly functioning fan maintains consistent airflow across the cooling system; a worn or damaged fan can lead to engine overheating and unplanned shutdowns during compaction operations.
- Verified Part Number Integrity: — Ordering by Wacker Neuson part number 5100012187 eliminates guesswork and confirms you are receiving the correct fan for your specific roller variant.
The cooling fan draws or pushes air across the engine's radiator and cooling fins to dissipate heat generated during operation. On asphalt and soil compaction equipment like the RD40-130 and RD45-140 tandem rollers, maintaining proper engine temperature is critical — these machines run continuously under load in demanding site conditions. When a fan blade cracks, becomes imbalanced, or loses efficiency, airflow drops and engine temperatures rise, which can trigger thermal shutdowns or cause long-term engine damage. Replacing a worn fan promptly with the correct OEM part keeps the cooling system operating as designed.
