The Wacker Neuson is a genuine OEM Valve Plate designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, US, and.3 variants. As a factory-sourced component, it meets the exact specifications set by Wacker Neuson for this hydraulic system, ensuring a direct, accurate replacement. This part covers an extensive range of RD-series configurations, making it the right choice whether you're servicing a base model or a variant-specific machine.
Key Features
- Genuine OEM Hydraulic Precision — Manufactured to Wacker Neuson's exact porting geometry and surface-finish tolerances, ensuring correct flow control and pressure sealing within the hydraulic circuit.
- Direct Drop-In Replacement — Matches the original mounting pattern and port configuration of the factory-installed valve plate, integrating cleanly into the existing hydraulic assembly.
- Broad RD-Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers across standard, C, O, US, and .3 model generations, covering a wide range of Wacker Neuson compact roller configurations.
- Sustained Hydraulic Performance — A correctly seated valve plate maintains consistent fluid distribution across the hydraulic system; a worn or damaged plate can cause pressure loss, erratic drum drive, and reduced compaction output.
- Verified OEM Part Number — Sourced directly under part number 5100013066, so you can order with confidence that this is the correct factory component for your machine.
The valve plate is a critical internal component within a hydraulic pump or motor assembly. It acts as the interface between the rotating cylinder block and the hydraulic ports, directing pressurized fluid in and out of the pump in a controlled sequence. When the valve plate wears, becomes scored, or loses its surface integrity, the hydraulic system loses efficiency — resulting in weak or uneven drum drive, overheating, and ultimately compaction performance that falls short of what the roller is rated to deliver.
