The Wacker Neuson Upper Mass is a genuine OEM component designed for BPU series reversible vibratory plate compactors, including the BPU 3545A, BPU 4045A, BPU 5045A, BPU 5545A, and their US-market variants. Sourced directly from Wacker Neuson, this part meets the original engineering specifications for the BPU platform, ensuring it seats and functions exactly as the factory-installed unit. Compatible across seven BPU configurations, the is the correct replacement for machines running the 45 cm working width format at force ratings from 35 kN to 55 kN.
Key Features
- Genuine OEM Mass Geometry — Manufactured to Wacker Neuson's original mass specifications, ensuring the correct weight distribution and vibratory balance critical to compaction output.
- Direct Bolt-On Replacement — Engineered to align with the existing exciter housing and mounting points on BPU 45 cm-width machines; installs without modification to surrounding components.
- Broad BPU Series Coverage — Fits BPU 3545A, BPU 4045A, BPU 5045A, BPU 5545A, and US-spec variants, making it the correct choice across a wide range of job-site BPU units.
- Compaction Force Integrity — A correctly matched upper mass maintains the designed amplitude and centrifugal force output; a worn or incorrect mass reduces compaction depth and surface consistency.
- Verified Genuine OEM Part — Part number 5000202014 is the authorised Wacker Neuson replacement, eliminating guesswork and ensuring fit on every covered model.
The upper mass is one of two eccentric masses housed within the exciter unit of a reversible vibratory plate compactor. Working together with the lower mass, it generates the centrifugal force that drives the baseplate into the ground in a controlled, directional pattern — giving BPU machines their reversible travel capability. The mass assembly is precisely weighted and timed; if the upper mass becomes damaged, worn, or out of balance, the plate will lose compaction force, exhibit erratic travel direction, or produce excessive vibration transmitted back into the machine frame. Replacing the upper mass with the correct OEM part restores designed amplitude and keeps the compactor performing to its rated output.
