Wacker Neuson 5100013374 Water Pump

The Wacker Neuson Water Pump is a genuine OEM Water Pump designed for the RD18, RD24, RD27, RD28, RD40, and RD45 series tandem rollers. As a factory-authorized component, this part is manufactured to the exact tolerances and flow specifications required by Wacker Neuson for these machines, ensuring the cooling system performs as intended across the full range of compatible models. The covers an extensive fitment list spanning standard, C, O, DPF, and electric-series variants, making it the correct choice for a wide range of RD-series roller configurations in both US and international markets.

Key Features

• OEM-Matched Flow and Pressure Ratings — Engineered to deliver the precise coolant flow rate and pressure the engine cooling circuit demands, preventing thermal overload during sustained compaction work.
• Direct-Mount Replacement — Bolts into the factory pump position on RD-series tandem rollers with original hardware and sealing surfaces, requiring no modification to the mounting flange or coolant lines.
• Broad RD-Series Fitment — Compatible with RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, including standard, C (cab), O (open), DPF, and electric-series variants across multiple production generations.
• Protects Engine from Overheating — A worn or leaking water pump causes coolant starvation, leading to elevated operating temperatures, forced shutdowns, and accelerated engine wear; a fresh pump restores full thermal regulation immediately.
• Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this component carries the part number 5100013374 and meets all original material and performance standards for the RD roller line.

The water pump is responsible for circulating coolant through the engine and radiator, drawing heat away from critical engine components and maintaining a stable operating temperature during demanding compaction cycles. On tandem rollers like the RD series, which often run for extended periods under load, consistent coolant circulation is essential to protect the engine and maintain productivity. When the water pump fails — through impeller wear, seal deterioration, or bearing failure — coolant flow drops, engine temperature climbs, and the machine may shut down to prevent damage, making prompt replacement essential to keeping operations on schedule.
