The Wacker Neuson is a genuine OEM Eccentric Weight designed for the BPU 4045A and DPU 4045 series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this part meets the exact specifications required to restore proper vibration output in your machine. Compatible fitment spans a wide range of BPU and DPU variants including the BPU 4045A, DPU 4045Ye, DPU 4045Yeh, DPU 4045Yehzf, DPU 40Yeh, and DPU 45Yeh in US, EU, and LRC configurations. Verify your model number before ordering to confirm this is the correct eccentric weight for your unit.
Key Features
- Genuine OEM Mass Tolerance: — Manufactured to Wacker Neuson's original weight specification, ensuring the correct centrifugal force and vibration amplitude are restored to the compactor.
- Drop-In Replacement: — Designed to mount directly onto the exciter shaft using the original bolt pattern, with no machining or modification to the housing required.
- Broad BPU and DPU Fitment: — Covers BPU 4045A, DPU 4045Ye, DPU 4045Yeh, DPU 4045Yehzf LRC, DPU 40Yeh US/EU, and DPU 45Yeh US/EU models.
- Restores Compaction Performance: — A worn, cracked, or missing eccentric weight directly reduces plate frequency and compaction force; replacing it brings output back to rated specification.
- Balanced Vibration Profile: — Correct weight mass prevents eccentric shaft imbalance that can accelerate bearing wear and cause excessive machine vibration during operation.
The eccentric weight is a core component of the vibratory exciter assembly inside a plate compactor. As the exciter shaft rotates at high speed, the offset mass of the eccentric weight generates centrifugal force, which drives the compaction plate up and down to consolidate soil, aggregate, or asphalt beneath it. On reversible plate compactors like the BPU and DPU series, the position or configuration of the eccentric weights also determines the direction of plate travel — forward or reverse. If an eccentric weight becomes cracked, loses mass, or separates from the shaft, vibration amplitude drops noticeably, compaction performance suffers, and the resulting shaft imbalance can rapidly damage bearings and the surrounding exciter housing.
