The Wacker Neuson is a genuine OEM Exciter Eccentric Assembly 1000Mm designed for the RD27-100 series tandem rollers, including Hydrostatic Vibratory Roller, Ride-On Roller, RD27-100 Roller Pro T4F, and RD27-100 Roller Basic T4F configurations. As a factory-sourced component, the is manufactured to the exact tolerancing and mass specifications required to deliver consistent vibratory output from the compaction drum. Confirmed fitment spans multiple RD27-100 production series, making this the straightforward, no-guesswork replacement for a worn or failed exciter assembly on your tandem roller.
Key Features
- OEM-Matched Eccentric Mass: — Manufactured to the precise offset weight and dimensional spec required to generate the correct centrifugal force and vibration amplitude for the 1000Mm drum width.
- Direct Drop-In Replacement: — Engineered to the original shaft interface and bearing housing dimensions of the RD27-100 drum assembly, supporting a straightforward swap without custom fitting.
- Broad RD27-100 Series Coverage: — Verified fitment across Hydrostatic Vibratory Roller, Ride-On Roller, Pro T4F, and Basic T4F variants of the RD27-100 platform.
- Restored Compaction Performance: — A correctly functioning eccentric assembly delivers the full-rated vibration frequency and amplitude, ensuring the roller achieves target compaction depth and density on asphalt and soil passes.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, carrying the part number 5000189393 for straightforward verification against your machine's parts manual.
The exciter eccentric assembly is the rotating counterweight mechanism housed inside the compaction drum that generates the vibratory force used to densify asphalt and soil. As the eccentric mass spins, it creates an imbalance that translates into rapid, controlled drum oscillation — the core action that drives compaction depth and uniformity across each pass. When the eccentric assembly wears, becomes damaged, or loses balance, vibration output drops or becomes erratic, resulting in uneven compaction density, increased pass counts, and potential long-term structural issues in the finished surface.
