The Wacker Neuson Upper Mass is a genuine OEM component designed for DPU 2870, DPU 2970, DPU 2950, and DPU 2960 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part matches the original specification and integrates seamlessly into the compactor's exciter and frame assembly. It is confirmed compatible across multiple DPU variants, including the 28 kN and 29 kN models in both 50 cm and 70 cm deck widths.
Key Features
- Genuine OEM Mass Geometry: — Cast and machined to the original weight and dimensional spec, ensuring the correct eccentric force and vibration frequency are maintained in the compaction cycle.
- Direct Drop-In Replacement: — Engineered to mount to the existing exciter housing on DPU-series plates without modification, using the same bolt pattern and attachment points as the factory part.
- Broad DPU Series Compatibility: — Fits the DPU 2870, DPU 2960, DPU 2950, and DPU 2970, covering both 50 cm/20 in and 70 cm/28 in deck configurations.
- Compaction Output Integrity: — A correctly weighted and balanced upper mass delivers consistent centrifugal force to the base plate, keeping compaction depth and surface finish within spec on soil and aggregate applications.
- Balanced Vibration Dynamics: — Worn or cracked upper mass components cause uneven vibration, reduced compaction force, and accelerated wear on surrounding exciter and bearing components — replacing with a genuine part restores proper dynamic balance.
The upper mass is a core structural and functional element of the exciter assembly in a reversible vibratory plate compactor. It works together with the lower eccentric mass to generate the centrifugal force that drives the base plate into the ground, producing the compaction energy needed for soil and aggregate densification. When the upper mass is damaged, worn, or out of balance, the machine loses compaction efficiency, vibration becomes erratic, and stress is transferred to bearings and the exciter housing — shortening the service life of the entire drive assembly.
