The Wacker Neuson Upper Mass is a genuine OEM component designed for DPU 3750 and DPU 3760 series diesel reversible plate compactors and the BPU 3750Ats gasoline reversible plate compactor. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. Compatible models include the DPU 3750Hts, DPU 3750Hets, DPU 3760Hts, DPU 3760Hets, BPU 3750Ats, BPU 3750Ats US, and DPU 3750Hts US — making a broadly applicable upper mass across this reversible plate compactor family.
Key Features
- Genuine OEM Mass Geometry: — Engineered to the exact weight, balance, and dimensional profile of the original, ensuring the vibration system operates within its designed excitation range.
- Direct Bolt-On Replacement: — Matches the original mounting interface on DPU 3750, DPU 3760, and BPU 3750Ats platforms — slides into place without reworking the exciter housing or baseplate assembly.
- Broad Fitment Across the 3750/3760 Family: — Covers DPU 3750Hts, DPU 3750Hets, DPU 3760Hts, DPU 3760Hets, BPU 3750Ats, BPU 3750Ats US, and DPU 3750Hts US models in a single part number.
- Restores Compaction Force Output: — A worn or damaged upper mass unbalances the exciter assembly and degrades compaction force, leading to uneven soil density and failed compaction passes. Replacing it restores the machine's rated centrifugal force output.
- Balanced Vibration Dynamics: — Correct upper mass weight is critical for smooth, controlled operation on reversible plates; an out-of-spec mass introduces excess vibration transmitted to the operator and frame components.
The upper mass is one half of the two-mass exciter system at the heart of a reversible vibratory plate compactor. Working in conjunction with the lower mass and eccentric shaft, it generates the centrifugal force that drives compaction energy into the soil or aggregate below the baseplate. The direction of travel on a reversible plate is controlled by shifting the phase relationship between the upper and lower masses — so a damaged or incorrectly weighted upper mass doesn't just reduce compaction output, it can also cause erratic directional behavior and unpredictable machine movement. Keeping this component in serviceable condition is essential to both compaction performance and operator control.
