The Wacker Neuson Eccentric Weight AR 3 is a genuine OEM component designed for the AR 3/2 series external concrete vibrators, including AR 3/2, AR 3/2 S, AR 3/2 W/S, and AR 3/2 460V 60Hz variants. As a direct factory replacement, this part is produced to the exact mass and geometry specifications required to maintain the correct vibration output in Wacker Neuson AR series external vibrators. Genuine OEM sourcing means you get the same part that was installed at the factory — no guesswork on dimensional compatibility across the full AR 3/2 model range.
Key Features
- Calibrated Eccentric Mass: — Manufactured to the precise off-center weight specification that determines vibration frequency and amplitude output in the AR 3/2 series.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, ensuring correct material grade and dimensional accuracy for this rotating component.
- Broad AR 3/2 Series Fitment: — Confirmed fit across AR 3/2, AR 3/2 S, AR 3/2 W/S, and AR 3/2 460V 60Hz external vibrator models.
- Restores Full Vibration Output: — A worn or damaged eccentric weight reduces compaction force and can cause uneven concrete consolidation; this replacement brings output back to specification.
- Balanced Rotating Assembly: — Correct eccentric weight mass is critical for rotor balance; an out-of-spec weight accelerates bearing wear and shortens motor service life.
The eccentric weight is the core vibration-generating component inside an external concrete vibrator. Mounted on the motor shaft, it creates the centrifugal force that vibrates the motor housing and, by extension, any formwork or mold the vibrator is clamped to. This vibration drives air bubbles out of freshly poured concrete and ensures the mix consolidates evenly around reinforcement. When the eccentric weight is worn, damaged, or out of balance, vibration output drops, compaction becomes inconsistent, and bearing loads increase — ultimately shortening the service life of the entire vibrator unit.
