The Wacker Neuson is a genuine OEM Valve Assembly designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers with traction control. As a direct Wacker Neuson OEM part, the is manufactured to the same specifications as the original component installed at the factory, ensuring a correct, trouble-free installation. This assembly is confirmed to fit all listed RD27-100 and RD27-120 machine configurations, so you can order with confidence that this is the right part for your roller.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original design tolerances, ensuring the valve seats, ports, and flow characteristics match what the RD27 hydrostatic system was engineered around.
- Direct Bolt-In Replacement — Designed to install in the same position and use the same connections as the original assembly, with no adapters or modifications needed to the hydraulic circuit.
- Verified RD27 Compatibility — Confirmed fitment for RD27-100 and RD27-120 hydrostatic vibratory rollers equipped with traction control, covering all four listed machine configurations.
- Hydraulic System Integrity — A correctly functioning valve assembly maintains proper fluid routing and pressure regulation within the hydrostatic drive, keeping traction control response accurate and drum vibration consistent during compaction passes.
- Hydraulic Safety Compliance — A faulty or leaking valve assembly can cause uncontrolled pressure fluctuations in the hydrostatic circuit, which may affect operator control and machine behavior on grade; using a genuine OEM replacement restores designed system behavior.
The valve assembly controls the routing and regulation of hydraulic fluid within the hydrostatic drive circuit of the RD27 tandem roller. By directing flow between the pump, motor, and traction control components, it governs how power is delivered to the drums and how the machine responds during forward, reverse, and vibratory operation. When this assembly wears, sticks, or fails, operators may experience sluggish or erratic drive response, loss of traction control function, or hydraulic fluid leaks that compromise the entire drivetrain.
