The Wacker Neuson Cooling Pump is a genuine OEM cooling pump designed for the RD40-130 and RD45-140 series tandem rollers, including C and O variants across both generation families. As a direct OEM part, the is built to the exact specification Wacker Neuson uses in production, ensuring a correct, straightforward installation with no guesswork on fitment. This cooling pump is compatible across a broad range of RD40-130 and RD45-140 configurations, covering standard, C, and O variants in both the original and.3 series builds. When your roller's cooling system needs attention, sourcing the right OEM component keeps the machine performing as engineered.
Key Features
- OEM Flow and Pressure Spec: — Built to the exact pump output specification Wacker Neuson requires for proper coolant circulation in these roller models — no compromise on flow rate or pressure.
- Direct Drop-In Replacement: — Matches the original mounting configuration and port connections on RD40-130 and RD45-140 series rollers for a clean, straightforward swap.
- Broad Series Fitment: — Covers RD40-130 and RD45-140 in standard, C, and O variants across both original and .3 generation builds, including models 5100011391 through 5100047400.
- Protects Engine from Thermal Damage: — A properly functioning cooling pump maintains consistent coolant flow; a worn or failed unit risks overheating the engine and forcing costly downtime on the compaction site.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, this is the same component used in original assembly — not a pattern copy or approximation.
The cooling pump circulates coolant through the engine and cooling system to regulate operating temperature during compaction work. It keeps the engine within its safe thermal range by moving coolant between the engine block and the radiator continuously while the machine runs. When the cooling pump wears out or fails, coolant flow drops or stops entirely, leading to rapid overheating, potential engine damage, and an unplanned halt to paving or compaction operations — making timely replacement essential.
