The Wacker Neuson Plunger is a genuine OEM component designed for the RD7A, RD7H, and RD7He series tandem rollers. Sourced directly from Wacker Neuson, this plunger is manufactured to the same specifications as the original part fitted at the factory, ensuring a true like-for-like replacement. It is confirmed to fit across multiple configurations of the RD7 tandem roller lineup, including the RD7A, RD7H, and RD7He models. When it comes to hydraulic and mechanical system integrity on your roller, using the correct OEM plunger helps maintain consistent performance and long service life.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original tolerances, ensuring the plunger delivers the correct stroke length and sealing contact for this application.
- Drop-In Replacement — Engineered to install directly into the original housing bore with no reworking of the surrounding components required.
- Broad RD7 Series Compatibility — Confirmed fitment across RD7A, RD7H, and RD7He tandem roller variants, covering a wide range of serial configurations in the RD7 lineup.
- Sustained System Pressure — A properly functioning plunger maintains consistent displacement and pressure delivery; a worn or damaged plunger can cause erratic system response and loss of compaction performance.
- Verified Part Number — Order with confidence using Wacker Neuson part number 5200011108 to confirm you are receiving the correct replacement for your machine.
A plunger is a precision-machined reciprocating component used within hydraulic or mechanical pump assemblies to generate and sustain pressure through a controlled back-and-forth motion. On a tandem roller like the RD7 series, the plunger plays a critical role in converting mechanical input into the hydraulic force needed to drive the machine's systems smoothly and consistently. When a plunger wears, scores, or fails, it can lead to pressure loss, sluggish response, or complete system failure — making timely replacement essential to keeping the roller operating at full compaction capacity.
