The Wacker Neuson Upper Mass is a genuine OEM component designed for the DPU 2540H, DPU 2550H, DPU 2560H, DPU 2560H-TS, BPU 2540A, and BPU 2540A US reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original assembly, ensuring proper fit and function within the compaction system. If your reversible plate is producing uneven vibration, excessive noise, or reduced compaction force, a worn or damaged upper mass is a likely cause. Replacing it with the correct OEM part restores the machine to its intended operating performance.
Key Features
- Genuine OEM Mass Geometry: — Machined to the original weight and dimensional spec, so vibratory output and compaction force match factory design intent for the BPU and DPU 2540–2560 series.
- Drop-In Compatibility: — Engineered to mount directly into the exciter housing of compatible DPU and BPU models without modification to surrounding components.
- Broad DPU and BPU Fitment: — Confirmed for DPU 2540H, DPU 2550H, DPU 2560H, DPU 2560H-TS, BPU 2540A, BPU 2540A US, and BPU 2540 reversible vibratory plate compactors.
- Restored Compaction Output: — A correctly weighted upper mass maintains the eccentric force balance that drives productive soil and aggregate compaction; an out-of-spec or damaged mass reduces plate amplitude and ground penetration.
- Vibration System Integrity: — Proper mass balance within the exciter assembly reduces stress on bearings and housing components, extending the service life of surrounding parts.
The upper mass is one of two eccentric weights housed inside the exciter unit of a reversible vibratory plate compactor. Working in opposition to the lower mass, it generates the centrifugal force that drives the baseplate into the ground and controls the direction of travel. The precise weight and rotational offset of the upper mass directly determine the amplitude and frequency of vibration delivered to the plate. When the upper mass is worn, cracked, or out of balance, the machine loses compaction effectiveness, may pull unevenly in one direction, and places added load on the exciter bearings — making timely replacement essential to keep the compactor performing at rated capacity.
