The Wacker Neuson Drive Piston Complete is a genuine OEM component designed for the EH 6 M and EHB 7 M series electric breakers, including 115V, 120V, and 230V variants. Sourced directly from Wacker Neuson, this assembly meets the exact specifications of the original part it replaces. Confirmed fitment spans the EH 6 M/115, EH 6 M/120, EH 6 M/230, EHB 7 M/115, EHB 7 M/120, and EHB 7 M/230 models, making the correct choice across the full range of these electric breaker configurations.
Key Features
- Genuine OEM Piston Assembly — Manufactured to Wacker Neuson's original dimensional and material tolerances, ensuring the drive piston delivers consistent stroke force and sealing performance within the breaker cylinder.
- Complete Drop-In Assembly — Supplied as a complete drive piston unit, so it installs directly into the breaker housing without requiring additional sub-components or machining.
- Broad Voltage Compatibility — Fits 115V, 120V, and 230V configurations of both the EH 6 M and EHB 7 M series, covering a wide range of jobsite power supply requirements.
- Restored Impact Energy — A worn or damaged drive piston causes a noticeable drop in blow energy and chisel output; replacing it with a correctly spec'd assembly restores full breaking performance.
- Electrical Safety Compliance — As a core internal component in an electric breaker, using a genuine OEM piston assembly ensures the tool continues to operate within its rated safety parameters under load.
The drive piston is the heart of an electric breaker's impact mechanism. It converts the motor's rotational energy into rapid, linear percussion strokes that deliver force to the chisel or tool bit. When the drive piston wears, cracks, or loses its sealing integrity, the breaker produces weaker blows, increased vibration, and may eventually stop breaking altogether — making timely replacement critical to keeping the tool productive on concrete, masonry, and demolition work.
