Wacker Neuson 5000034700 Eccentric Drive Weight, 2.5 Mm

The Wacker Neuson Eccentric Drive Weight, 2.5 Mm is a genuine OEM component designed for the AR 75 series external concrete vibrators, including the AR 75/9/042, AR 75/10,8/046, and AR 75/9/250 models. As a direct factory replacement, this part is manufactured to the exact mass and dimensional tolerances required for proper vibration output in Wacker Neuson AR series units. Sourcing a genuine OEM part like the ensures the eccentric assembly performs exactly as engineered, maintaining the vibration frequency and amplitude your application demands.

Key Features

• Calibrated Mass for Correct Vibration Output — At 2.5 mm specification, this eccentric weight is precisely sized to deliver the designed centrifugal force, keeping vibration amplitude consistent and predictable during concrete consolidation.
• Genuine OEM Construction — Manufactured by Wacker Neuson to original equipment specifications, this part matches the material grade and geometry of the factory-installed component in AR 75 series vibrators.
• Direct Drop-In Replacement — Engineered to install directly into the eccentric drive assembly of compatible AR 75 units without modification to housings, shafts, or fasteners.
• Broad AR 75 Series Compatibility — Confirmed fitment across the AR 75/9/042, AR 75/10,8/046, and AR 75/9/250 external vibrator models, covering multiple voltage and RPM configurations within the AR 75 family.
• Protects Bearing and Housing Life — A worn or incorrectly weighted eccentric creates imbalance that accelerates bearing wear and stresses the vibrator housing. Replacing with the correct 5000034700 weight restores balanced rotation and protects surrounding components.

The eccentric drive weight is the core element responsible for generating vibration in an external concrete vibrator. As the motor spins the eccentric shaft, the off-center mass of the weight creates centrifugal force, which is transmitted through the vibrator housing and into concrete formwork or molds to consolidate the mix and eliminate air voids. If the eccentric weight is worn, damaged, or replaced with an incorrectly sized part, vibration output becomes inconsistent — leading to under-consolidated concrete, surface voids, or uneven structural density. Using the correct OEM-spec weight, such as the Wacker Neuson 5000034700, ensures the vibrator delivers the amplitude and frequency the application requires.
