The Wacker Neuson is a genuine OEM Valve Kit designed for the RD27-100 and RD27-120 hydrostatic vibratory rollers, including standard and traction control configurations. As a direct OEM replacement, this kit is manufactured to the same specifications as the original component, ensuring a correct installation into the hydraulic system without guesswork. Fitment covers multiple machine configurations across the RD27-100 and RD27-120 series, making this the right choice whether you are servicing a standard unit or a traction control variant. Keep the Wacker Neuson on hand to stay ahead of hydraulic system maintenance on your RD27 roller fleet.
Key Features
- OEM-Specified Valve Tolerances — Manufactured to exact hydraulic flow and pressure ratings required by the RD27 drivetrain, ensuring consistent valve response across the full operating range.
- Direct-Fit Hydraulic Connection — Designed to connect directly into the existing hydraulic circuit of the RD27-100 and RD27-120, with port sizing and thread specifications matched to the original installation.
- Broad RD27 Series Coverage — Compatible with RD27-100 and RD27-120 models in both standard hydrostatic and traction control configurations, covering a wide range of machine serial number ranges.
- Restored Hydraulic Drive Performance — A worn or leaking valve can cause erratic propulsion, loss of compaction force, or traction inconsistencies; this kit restores precise hydraulic control to keep the roller performing accurately.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, this kit carries full OEM provenance for confidence in part authenticity and longevity.
The valve kit within a hydrostatic vibratory roller controls the flow and direction of hydraulic fluid through the drive and vibration circuits. On machines like the RD27-100 and RD27-120, the hydraulic valve governs propulsion speed, direction, and in traction control models, the automatic wheel-slip correction function. When a valve wears, sticks, or develops internal leakage, operators may notice sluggish or uneven drive response, loss of vibratory force, or reduced traction control effectiveness — all of which directly impact compaction quality and machine safety on grade.
