The Wacker Neuson is a genuine OEM V-Belt Pulley Half designed for the 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 design tolerances for the BPU drive system, ensuring the belt seats and tracks correctly under the heavy cyclic loads these machines generate. It is a confirmed fitment for both standard and US-specification models in the BPU 3545A through BPU 5545A range. When you need to restore the drive system on your reversible plate to full working order, part number is the correct OEM replacement.
Key Features
- OEM-Matched Pulley Geometry — Manufactured to the original groove angle and pitch diameter so the V-belt runs true, without slipping or uneven wear on the belt flanks.
- Direct Bolt-On Replacement — Matches the original hub bore, keyway, and flange dimensions of the BPU drive assembly for a straightforward swap with standard workshop tooling.
- Broad BPU Series Fitment — Confirmed for BPU 3545A, BPU 4045A, BPU 5045A, and BPU 5545A models, covering both standard and US-market configurations.
- Sustained Drive Efficiency — A correctly profiled pulley half maintains full belt tension and power transfer to the exciter, keeping compaction force consistent across the plate.
- Genuine Wacker Neuson OEM Part — Supplied under part number 5000109333 direct from the Wacker Neuson parts chain, with no substitutions or reverse-engineered dimensions.
The V-Belt Pulley Half is one of the two mating sheave halves that grip and drive the V-belt connecting the engine to the exciter unit on a reversible vibratory plate compactor. Together, the pulley halves create the correct belt contact angle that transmits engine torque efficiently to generate the compaction vibration the plate relies on. When a pulley half is worn, cracked, or damaged, the belt loses its seating surface, causing slip, rapid belt wear, and a loss of exciter speed — which directly reduces compaction performance and can leave the plate unable to reverse direction cleanly.
