The Wacker Neuson Eccentric Weight is a genuine OEM component designed for the AR 43/3 and AR 43/6 series compaction equipment. Sourced directly from Wacker Neuson, this part meets the same specifications as the original installed at the factory, ensuring a correct, direct-replacement fit. Compatible across multiple AR 43 configurations including the AR 43/3/230 v, AR 43/3/400, AR 43/6/042, and AR 43/6/250, the is the right part when you need to restore your machine to full working condition.
Key Features
- OEM-Grade Mass Consistency — Manufactured to exact weight and dimensional tolerances, ensuring the eccentric force output matches the original design specification for your AR 43 series machine.
- Direct Bolt-In Replacement — Engineered to mount directly onto the existing eccentric shaft assembly with no reworking of surrounding components required.
- Broad AR 43 Series Coverage — A single part number covers the AR 43/3/230 v, AR 43/3/400, AR 43/6/042, and AR 43/6/250 models, making it the correct choice across the AR 43 range.
- Restored Compaction Performance — A worn or damaged eccentric weight causes uneven vibration output and reduced compaction force; replacing it with this genuine OEM part brings amplitude and frequency back to spec.
- Genuine Wacker Neuson Part — Supplied as an authentic OEM component with the correct part number 5100002940, eliminating guesswork and ensuring full traceability.
The eccentric weight is a core element of a vibratory compactor's drive mechanism. Mounted on a rotating shaft inside the machine, its offset mass generates the centrifugal force that produces the vibration needed to compact soil, gravel, or asphalt. If the eccentric weight becomes damaged, cracked, or worn, the machine will produce inconsistent or diminished vibration, resulting in poor compaction depth and uneven surface results. Replacing a failed eccentric weight promptly restores the designed vibration amplitude and keeps the compactor performing as intended.
