The Wacker Neuson is a genuine OEM Exciter Shaft designed for RD27-100 and RD27-120 series tandem rollers, including Hydrostatic Vibratory and Traction Control configurations. As a factory-original component, the is manufactured to the exact tolerances required for proper eccentric mass rotation and consistent vibratory output. This part fits across multiple machine configurations within the RD27 family, making it the correct choice for operators maintaining or rebuilding their rollers. Verify your machine number against the fitment list to confirm compatibility before ordering.
Key Features
- Genuine OEM Eccentric Precision — Factory-original shaft machined to exact balance and dimensional specifications critical for consistent drum vibration amplitude.
- Direct Drop-In Replacement — Matches the original mounting interfaces and spline or journal geometry of the RD27 exciter assembly, allowing straightforward installation.
- Broad RD27 Family Coverage — Confirmed fitment across RD27-100 and RD27-120 configurations, including standard Hydrostatic Vibratory and Traction Control variants.
- Restores Full Compaction Performance — A worn or damaged exciter shaft causes erratic or reduced drum vibration, leading to uneven compaction and failed density tests; replacing it brings output back to spec.
- Verified Wacker Neuson Part Number — Sourced directly from Wacker Neuson, so you receive the correct component without the risk of dimensional mismatches common with unverified alternatives.
The exciter shaft is the core rotating element inside the vibratory drum assembly of a tandem roller. As it spins, the eccentric mass mounted on or around the shaft generates the centrifugal force that drives the drum's up-and-down vibration — the mechanism responsible for densifying asphalt and soil beneath the machine. If the exciter shaft becomes worn, cracked, or damaged, vibration output drops or becomes inconsistent, which directly compromises compaction quality and can lead to costly rework on paving or grading projects.
