The Wacker Neuson 5100012875 is a genuine OEM Cooling Pump designed for the RD24-100, RD27-120, and RD28-120 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component installed at the factory. It is compatible across a broad range of RD-series configurations including standard, open-ROPS, canopy, and combination drum variants. Whether you are servicing a walk-behind or ride-on articulated tandem roller, part number 5100012875 is the correct OEM replacement for these machines.
Key Features
- Genuine OEM Cooling Efficiency: — Engineered to deliver the precise flow rate and pressure required to maintain safe operating temperatures in Wacker Neuson RD-series tandem roller engines.
- Direct-Fit Replacement: — Matches the original mounting configuration and port dimensions, allowing straightforward installation without modification to fittings or brackets.
- Broad RD-Series Compatibility: — Confirmed fit across RD24-100, RD27-120, and RD28-120 models in standard, open-ROPS, canopy, and combination configurations, covering both US and international variants.
- Protects Engine from Thermal Damage: — A correctly functioning cooling pump keeps coolant circulating at the right rate; a worn or failing pump leads to overheating, loss of power, and potential engine damage during compaction operations.
- Verified OEM Part Number: — Ordering by Wacker Neuson part number 5100012875 eliminates guesswork and ensures you receive the correct pump for your specific roller configuration.
The cooling pump circulates engine coolant through the cooling system, drawing heat away from the engine block and cylinder head and transferring it to the radiator where it can be dissipated. On ride-on tandem rollers like the RD24-100, RD27-120, and RD28-120, the engine works under sustained load during asphalt and soil compaction passes, making consistent coolant flow critical to preventing overheating. When the cooling pump begins to fail — through wear on the impeller, a failing seal, or bearing degradation — coolant flow drops, engine temperatures rise, and the machine may shut down or sustain internal damage if the condition goes uncorrected.
