The Wacker Neuson 5100011943 is a genuine OEM Closure Cock Ball designed for the full range of Wacker Neuson RD-series tandem rollers, including the RD18, RD24, RD27, RD28, RD40, and RD45 model families. Sourced directly from Wacker Neuson, this part carries the same specifications and materials as the original component fitted at the factory. Fitment spans an extensive range of RD-series configurations — standard, combination, open-ROPS, cab, and DPF variants — making part number 5100011943 a widely applicable service item across the RD tandem roller lineup.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the valve seats and closes with the same fluid-tight performance as the original.
- Direct Bolt-In Replacement — Engineered to match the original port threading and body dimensions, so installation follows the same procedure as the factory-fitted component with no re-engineering of the surrounding plumbing.
- Broad RD-Series Compatibility — A single part number covers RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers across walk-behind and ride-on articulated configurations, including DPF, open-ROPS, cab, and combination variants.
- Fluid Control Precision — A correctly functioning closure cock ball provides positive shutoff with no seep or weep; a worn or damaged ball valve can cause uncontrolled fluid loss, making this a high-priority service item during any fluid-system maintenance interval.
- Fuel or Fluid System Safety — As a shutoff valve component within the machine's fluid circuit, a secure-seating ball is critical to preventing unintended flow during service, reducing the risk of spills or hazardous conditions on site.
A closure cock ball is the spherical valve element inside a ball-type shutoff cock — rotating it a quarter-turn opens or closes the fluid passage completely. On Wacker Neuson RD-series tandem rollers, this component is used to isolate sections of the fuel or fluid circuit during servicing, allowing technicians to safely stop flow without draining entire systems. When the ball becomes worn, corroded, or fails to seat properly, the valve can no longer hold a reliable shutoff, leading to fluid seepage past the closed position and potential contamination or loss of critical machine fluids.
