The Wacker Neuson Charge Relief Kit is a genuine OEM component designed for the RD12A-90, RD12-90, RD7H, RD7, and RD11 series double drum vibratory rollers. As a factory-sourced kit, it delivers the exact specifications required to restore correct hydraulic charge circuit function across this broad range of Wacker Neuson tandem rollers. This kit covers multiple configurations including solid ROPS, foldable ROPS, and EU-spec variants, making it the right choice whether you're servicing a standard production unit or a specialized configuration. Keep part number on hand as a planned service component to stay ahead of hydraulic system wear.
Key Features
- OEM Hydraulic Pressure Spec: — Sourced directly from Wacker Neuson, this kit includes components manufactured to the exact pressure relief tolerances required for the charge circuit — no guesswork on valve calibration or seat fitment.
- Kit Format for Complete Service: — Supplied as a ready-to-install kit with all necessary components for a full charge relief service, so you're not sourcing individual parts separately.
- Broad Tandem Roller Coverage: — Confirmed fitment across RD12A-90, RD12-90, RD7H-ES, RD7H-S, RD7, RD11A, RD11V, and RD11AEC series rollers, including foldable ROPS and EU-spec variants.
- Restores Drive Circuit Stability: — A worn or failed charge relief valve can cause erratic drive response, overheating, and loss of propulsion. This kit returns the hydraulic system to its correct operating parameters.
- Hydraulic System Safety: — Correct charge circuit relief pressure is critical to preventing hydraulic overpressure events. Using a genuine OEM kit ensures the relief threshold is set to the manufacturer's designed safety margin.
The charge relief kit services the charge relief valve within the hydraulic drive circuit of a double drum vibratory roller. This valve regulates pressure in the low-pressure charge circuit that keeps the closed-loop hydrostatic drive system primed and protected — without it functioning correctly, the drive pump can cavitate, overheat, or fail entirely. When the relief components wear or leak, operators typically notice sluggish or uneven propulsion, excessive heat buildup in the hydraulic system, or complete loss of drive, making timely replacement essential to keeping the machine productive on site.
