The Wacker Neuson 5100012244 is a genuine OEM Discharge Valve designed for the RD series ride-on tandem rollers, covering a wide range of configurations across the RD18, RD24, RD27, RD28, RD40, and RD45 model families. As a factory-sourced component, it meets the exact specifications set by Wacker Neuson for use in these articulated asphalt and soil compaction machines. This valve is a direct OEM replacement, ensuring the hydraulic or fluid system it serves operates as originally engineered. Cross-reference your machine's model number against the fitment list to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this discharge valve is manufactured to the precise flow and pressure tolerances required for correct operation in RD series tandem rollers.
- Drop-In Replacement — Engineered to match the original mounting configuration and port dimensions, allowing straightforward installation without modification to the existing system.
- Broad RD Series Fitment — Compatible with multiple configurations of the RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers, including C, O, and US market variants across standard and .3 series builds.
- Protects System Integrity — A correctly functioning discharge valve maintains proper fluid direction and pressure within the roller's system; a failed or leaking valve can cause loss of control over compaction drum operation and uneven output.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5100012244, the correct OEM reference for this application across all listed fitment variants.
A discharge valve controls the direction and release of fluid within the machine's hydraulic or fluid circuit, acting as a one-way or controlled-flow gate that manages where pressurized fluid travels during operation. In a tandem roller like the RD series, proper valve function is essential to maintaining consistent drum drive and vibration output — the core mechanisms that determine compaction quality. When a discharge valve wears, sticks, or fails, the system may lose pressure, behave erratically, or prevent the machine from compacting effectively, making timely replacement critical to keeping the roller productive on asphalt and soil applications.
