The Wacker Neuson Piston is a genuine OEM Piston designed for the BPU 3050A, BPU 3545A, BPU 4045A, and BPU 3750Ats series reversible vibratory plates. As a direct Wacker Neuson OEM component, part is manufactured to the same specifications as the original, ensuring a correct drop-in fit within the engine assembly. This piston covers both standard and US-market variants across the BPU series lineup, making it a straightforward choice when you need a verified replacement. Keep your vibratory plate running at full compaction force by sourcing the correct OEM part the first time.
Key Features
- OEM Dimensional Accuracy — Manufactured to exact bore and ring-groove tolerances, ensuring proper compression seal and consistent power stroke output in the engine.
- Direct Engine Assembly Fit — Installs into the cylinder bore using the same orientation and retention method as the original, with no adaptation needed to the connecting rod or cylinder.
- Broad BPU Series Coverage — Compatible with BPU 3050A, BPU 3545A, BPU 4045A, and BPU 3750Ats vibratory plates, including US-market variants of each model.
- Sustained Compaction Performance — A correctly fitted piston maintains the compression ratio the engine depends on; a worn or scored piston causes power loss, increased oil consumption, and reduced plate force.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, part number 5000217476 carries full OEM traceability for service records and fleet maintenance documentation.
The piston is a core reciprocating component inside the engine, converting combustion pressure into the downward force that drives the crankshaft and ultimately powers the exciter mechanism of the vibratory plate. It works in tight tolerance with the cylinder bore and piston rings to maintain compression, control oil consumption, and transfer energy efficiently with each firing cycle. When a piston wears, cracks, or scores — typically from overheating or lubrication failure — compression drops sharply, the engine loses pulling power, and the plate's compaction output falls well below rated performance.
