The Wacker Neuson Water Pump Complete is a genuine OEM component designed for the RD27-100 and RD27-120 series hydrostatic vibratory and tandem ride-on rollers. Sourced directly from Wacker Neuson, this complete assembly ensures the cooling system operates exactly as engineered — no guesswork, no adapting around missing pieces. It is a verified direct replacement for multiple RD27 configurations, including Pro and Basic T4F variants, covering a wide range of production series across both the RD27-100 and RD27-120 families. When your roller's water pump fails, getting the right complete assembly back in place fast is critical to protecting the engine and keeping your compaction schedule on track.
Key Features
- OEM Cooling Integrity — Engineered to Wacker Neuson's exact flow rate and pressure specifications, so the cooling circuit performs the way it was designed from day one.
- Complete Assembly, Ready to Install — Supplied as a fully assembled unit with all internal components included, dropping directly into the existing mounting position on RD27 series rollers.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 hydrostatic vibratory rollers, tandem rollers, Pro T4F, and Basic T4F variants across multiple production series.
- Protects Engine from Thermal Damage — A correctly functioning water pump maintains steady coolant circulation; a failed pump leads to rapid overheating and potential engine damage during compaction work.
- Genuine Wacker Neuson OEM Part — Manufactured to the same standards as the original unit, with materials and tolerances matched to the RD27 platform's thermal and mechanical demands.
The water pump circulates coolant through the engine and radiator to regulate operating temperature during heavy compaction cycles. On a ride-on roller like the RD27 series, consistent cooling is essential — the engine works under sustained load, and any drop in coolant flow can push temperatures into a dangerous range within minutes. When a water pump begins to fail, signs include coolant leaks at the pump housing, rising temperature gauge readings, or visible weeping around the shaft seal. Replacing the pump as a complete assembly restores full system integrity and eliminates the risk of a partial repair leaving marginal components in place.
