The Wacker Neuson Upper Mass is a genuine OEM component designed for the BPU 5045A and BPU 3545A reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original, ensuring it integrates correctly with the machine's exciter and isolation system. It is a direct fit for both the 50 kN and 35 kN BPU A-series reversible plates without adaptation.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's original mass and balance specifications, ensuring the upper mass performs correctly within the compactor's vibration isolation system.
- Direct-Fit Replacement — Engineered to bolt directly into place on BPU 5045A and BPU 3545A platforms, aligning with existing mounting points and hardware.
- BPU A-Series Compatibility — Confirmed fitment across the 50 kN BPU 5045A and 35 kN BPU 3545A reversible vibratory plate compactor models.
- Vibration Isolation Restored — A correctly functioning upper mass absorbs and isolates compaction forces from the operator handles and controls; a worn or damaged unit transmits excess vibration, accelerating wear on surrounding components and reducing operator control.
- Long-Term Compaction Output — Maintaining the correct mass balance ensures consistent centrifugal force output and effective soil or aggregate compaction on every pass.
The upper mass is a core structural component of the BPU reversible vibratory plate's two-mass exciter system. It sits above the lower exciter housing and is connected via isolation mounts, allowing the baseplate to vibrate at high frequency while dampening those forces before they reach the upper frame and operator controls. When the upper mass is cracked, deformed, or its isolation elements have failed, the machine loses effective vibration separation — resulting in reduced compaction efficiency, increased operator fatigue, and potential damage to the machine's control components over time.
