The Wacker Neuson Piston is a genuine OEM Piston designed for the EH 6 M and EHB 7 M series electric breakers, including 115V, 120V, and 230V variants. As a direct OEM part, it is manufactured to the same specification as the original component installed at the factory, ensuring a consistent, like-for-like replacement. This piston fits across multiple voltage configurations of both the EH 6 M and EHB 7 M breaker lines, making it a single trusted solution for fleets running mixed-voltage machines. Confirm your model number against the fitment list before ordering to ensure correct application.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to exact bore and stroke tolerances required for consistent percussion action in Wacker Neuson electric breakers.
- Drop-In Replacement — Engineered to the same geometry as the original piston, allowing installation without modification to the cylinder bore or internal components.
- Broad Voltage Compatibility — Fits both EH 6 M and EHB 7 M series breakers across 115V, 120V, and 230V configurations, covering a wide range of jobsite power supplies.
- Sustained Impact Performance — A correctly fitted piston maintains full percussion energy transfer to the tool steel; a worn or damaged piston results in reduced breaking force and increased operator fatigue.
- Genuine Wacker Neuson Part — Sourced directly through authorized Wacker Neuson supply channels, backed by part number 5000217678 for straightforward verification and procurement.
The piston is the core reciprocating component inside an electric breaker's percussion mechanism. It cycles rapidly under pneumatic or electro-mechanical force to drive the tool steel into the work surface, delivering the impact energy that breaks up concrete, asphalt, and masonry. When a piston wears, cracks, or loses its sealing surface, impact energy drops sharply, the breaker runs rough, and continued operation risks damaging the cylinder bore — turning a straightforward piston swap into a far more extensive repair.
