The Wacker Neuson is a genuine OEM V-Belt Pulley designed for BPU and DPU series reversible vibratory plate compactors. Sourced directly through Wacker Neuson's authorized parts network, this V-Belt Pulley is an exact factory replacement that installs without modification to the drive system. Compatible across a wide range of models including the BPU 3545A, BPU 5045A, BPU 5545A, DPU 4045H, DPU 5045H, DPU 4545H, and DPU 5545H series, this part covers one of the broadest fitment ranges in the reversible plate compactor lineup. When your drive components need attention, the Wacker Neuson ensures the power transfer system is restored to original operating condition.
Key Features
- Genuine OEM Belt-Drive Geometry — Machined to the exact groove profile and diameter spec of the original pulley, ensuring correct belt tension and alignment from the first start.
- Drop-In Drive System Fit — Designed to mount directly onto the engine output shaft of BPU and DPU compactors, matching the original bore, keyway, and fastener pattern.
- Wide BPU and DPU Series Coverage — A single part number serves the BPU 3545A, BPU 5045A, BPU 5545A, DPU 4045H, DPU 4545H, DPU 5045H, and DPU 5545H families, including H, He, Heh, Hec, Heap, and Hech variants.
- Preserves Compaction Force Output — A worn or slipping pulley robs the exciter of rotational energy, reducing centrifugal force and compaction depth; replacing with the correct OEM pulley restores full plate performance.
- Matched to Diesel and Gasoline Drive Configurations — Fits both diesel-powered DPU models and gasoline-powered BPU models within the 40–55 kN compaction force range, covering the most common mid-to-heavy reversible plate sizes in the Wacker Neuson range.
The V-belt pulley sits on the engine output shaft and transmits power from the engine to the exciter unit via a V-belt drive. By spinning at a precisely controlled diameter ratio, it sets the exciter speed that determines the plate's vibration frequency and compaction force. When the pulley wears, cracks, or loses its groove profile, the belt begins to slip or mistrack — reducing vibration output, accelerating belt wear, and ultimately causing inconsistent compaction results. Replacing a damaged pulley with the correct OEM part restores the designed drive ratio and keeps the compactor performing to its rated centrifugal force specification.
