The Wacker Neuson 5100045996 Gas Engine is a genuine OEM power unit designed for the BPU series reversible vibratory plate compactors, including the BPU 3050A, BPU 3750Ats, and BPU 4045A US models. As a direct OEM component sourced through Wacker Neuson's authorized parts network, this gas engine is manufactured to the same specifications as the original unit installed at the factory. Fitment extends across both standard and US-market BPU configurations, making this the correct replacement for operators running any of the covered models. Verify your machine's model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Power Output Match — Engineered to deliver the same horsepower and torque characteristics as the original engine, ensuring the compactor's vibration system performs as intended across soil and aggregate applications.
- Direct Drop-In Replacement — Mounts to the existing BPU compactor frame using the original bolt pattern and connection points, streamlining the engine swap without custom fitment work.
- Broad BPU Series Compatibility — Confirmed fitment across BPU 3050A, BPU 3050A US, BPU 3750Ats, BPU 3750Ats US, and BPU 4045A US reversible plate compactor models.
- Sustained Compaction Performance — A properly functioning engine sustains the centrifugal force needed for effective bi-directional compaction; a worn or underpowered engine reduces plate frequency and compaction depth.
- Fuel System Integrity — As the primary fuel-burning component, a genuine OEM gas engine maintains correct fuel-to-power conversion and reduces the risk of fuel system irregularities caused by out-of-spec substitutes.
The gas engine is the primary power source for the BPU reversible vibratory plate compactor, driving the exciter unit that generates the compaction force transmitted through the baseplate. On reversible plate compactors, the engine must deliver consistent output in both forward and reverse travel directions, making power stability critical to compaction quality on soil, gravel, and aggregate base material. When an engine loses compression, develops fuel delivery problems, or fails entirely, the plate loses compaction force and the machine becomes inoperable — making a like-for-like engine replacement the fastest path back to full productivity.
