The Wacker Neuson Water Pump is a genuine OEM component designed for the RD27-100 and RD27-120 Hydrostatic Vibratory Rollers. As a direct OEM replacement, this part is manufactured to the same specifications as the original, ensuring a verified fit across all covered RD27 configurations. Fitment is confirmed for both the RD27-100 and RD27-120 series, covering multiple machine builds within each model line. When the cooling circuit needs attention, sourcing the correct OEM water pump protects the integrity of the entire system.
Key Features
- OEM-Matched Flow and Pressure Output — Manufactured to the same internal tolerances as the original, maintaining proper coolant circulation rates specific to the RD27 drivetrain and engine package.
- Direct Drop-In Replacement — Engineered to mount using the existing bolt pattern and connect to the existing hose fittings on the RD27-100 and RD27-120, with no additional adapters needed.
- Confirmed Fitment for RD27 Series — Verified for RD27-100 and RD27-120 Hydrostatic Vibratory Rollers across multiple production builds, so you can order against your machine with confidence.
- Sustained Drum and Engine Cooling — A functioning water pump keeps coolant moving through the engine continuously; a failing pump leads to overheating, unplanned shutdowns, and potential engine damage during compaction operations.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the same part number — 5000162202 — used by authorized dealers and service centers worldwide.
The water pump is responsible for circulating coolant through the engine's cooling system, drawing heat away from critical components and maintaining safe operating temperatures. On a tandem roller like the RD27-100 and RD27-120, where the machine runs under sustained load during asphalt and soil compaction passes, consistent coolant flow is essential to preventing thermal stress on the engine. When a water pump begins to fail — whether through seal wear, impeller degradation, or bearing failure — coolant flow drops, temperatures rise, and the machine becomes vulnerable to overheating that can cause costly engine damage if left unaddressed.
