Key Features
- OEM Vibration Integrity — Manufactured to the original eccentric weight and core dimensions, maintaining the correct vibration frequency and amplitude the M1500 and M2500 series are built to deliver.
- Drop-In Core Replacement — Engineered to fit directly into the vibrator head housing with the same connection points as the original, so no rework or adapting is needed during installation.
- Broad Series Compatibility — Fits M1500 and M2500 series vibrators across 120V US, 230V EU, and 120V GB voltage variants, making it a practical stock item for mixed fleets.
- Restores Full Consolidation Performance — A worn or damaged inner core reduces vibration output, leading to poor concrete consolidation. Replacing with a genuine OEM core restores full compaction effectiveness.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5100069823 carries the full backing of the OEM, so you know it meets every specification of the original component.
The inner core complete is the heart of a concrete vibrator head — it contains the eccentric rotating mass that generates the high-frequency vibration used to consolidate freshly poured concrete. When the vibrator is running, the inner core spins at high speed inside the head housing, creating the outward vibration that causes air pockets and voids to rise out of the mix. When the inner core wears, becomes unbalanced, or fails, vibration output drops noticeably, resulting in under-consolidated concrete that can compromise structural integrity — making timely replacement essential to both pour quality and on-site safety.
