The Wacker Neuson is a genuine OEM Oil Cooler designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers. As a direct OEM part, the is manufactured to the same specifications as the original component installed at the factory, ensuring a correct fit across all covered RD27 configurations. Keeping the hydraulic and drivetrain oil operating within the correct temperature range is critical on a roller working continuously in demanding compaction cycles, and this cooler is built to hold up in exactly those conditions. Confirm your model number against the fitment list before ordering to ensure this is the right cooler for your machine.
Key Features
- OEM-Grade Thermal Capacity — Engineered to match the original heat-dissipation rating of the RD27 cooling circuit, maintaining consistent hydraulic oil temperature under sustained load.
- Direct-Fit Replacement — Matches the original mounting points, port sizing, and line connections of the factory cooler, so installation follows the same procedure as the component being replaced.
- RD27 Series Compatibility — Verified fitment for RD27-100 and RD27-120 hydrostatic vibratory rollers across multiple machine serial ranges.
- Protects the Hydraulic System — A failing oil cooler allows hydraulic fluid temperatures to climb, accelerating seal wear, degrading fluid viscosity, and placing the hydrostatic drive at risk of premature failure.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you receive the same component supplied for factory builds and authorized service repairs.
The oil cooler in a hydrostatic vibratory roller is responsible for drawing excess heat out of the hydraulic fluid as it circulates through the drive and vibration systems. On a machine like the RD27, where the hydrostatic transmission and drum vibration circuits run simultaneously under continuous duty, managing oil temperature is essential to keeping those systems operating correctly. When the cooler becomes blocked, leaks, or loses efficiency, hydraulic fluid overheats — leading to loss of drive response, increased wear on pumps and motors, and the potential for unplanned stops mid-job.
