The Wacker Neuson Exciter Shaft is a genuine OEM component designed for the RD12, RD16, and CB14B-900 series tandem and vibratory rollers. As a direct OEM replacement, this shaft is manufactured to the same specifications as the original part, ensuring proper eccentric mass alignment and consistent vibration output across the drum assembly. Fitment covers a broad range of configurations including solid ROPS, foldable ROPS, and hydrostatic double drum models within the RD11, RD12, RD12A, RD16-90, and CB14B-900 series. When your roller's vibration system needs attention, the is the correct part to restore full compaction capability.
Key Features
- Genuine OEM Precision Machining — Manufactured to exact eccentric mass and shaft diameter tolerances, ensuring the vibration frequency and amplitude your roller was designed to produce are fully restored.
- Drop-In Drum Assembly Replacement — Engineered to seat and align within the drum housing exactly as the original, with no rework to bearing housings or mounting flanges required.
- Broad RD and CB Series Coverage — Fits RD11, RD11A, RD11AEC, RD11V, RD12, RD12A, RD16-90, and CB14B-900 configurations including hydrostatic, foldable ROPS, and solid ROPS variants.
- Restores Full Compaction Output — A worn or failed exciter shaft reduces centrifugal force and drum amplitude, leaving lifts under-compacted. Replacing it with the correct OEM shaft brings compaction force back to spec.
- Verified Genuine Wacker Neuson Part — Sourced directly through authorized Wacker Neuson supply channels, so you know part number 5000111051 is exactly what the machine calls for.
The exciter shaft is the rotating eccentric component housed inside the vibratory roller drum. As it spins, the off-center mass generates centrifugal force that causes the drum to vibrate vertically, delivering the compaction energy needed to consolidate soil and asphalt lifts uniformly. When the exciter shaft wears, cracks, or fails, drum vibration weakens or stops entirely — resulting in poor compaction density, failed compaction tests, and potential rework of the entire lift. Keeping this shaft in good condition is fundamental to the roller performing its core job.
