The Wacker Neuson Striker Piston is a genuine OEM component designed for the EH 27 series electric demolition breakers, including the EH 27/115, EH 27/120 Low Vib, EH 27/127 Low Vib, and EH 27/127 models. Sourced directly from Wacker Neuson, this part carries the exact specifications required to restore full impact performance to your breaker. Fitment covers both standard and Low Vibration variants within the EH 27 family, making the correct choice across the lineup. If your breaker has lost striking force or stopped cycling, the striker piston is one of the first wear components to inspect and replace.
Key Features
- Genuine OEM Impact Tolerancing — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the correct hardness and surface finish critical for a high-cycle striker component.
- Drop-In Breaker Cylinder Fit — Engineered to seat directly into the EH 27 breaker cylinder bore without machining or shimming, restoring the correct piston-to-cylinder clearance on installation.
- EH 27 Series Coverage — Confirmed fitment for the EH 27/115 (110V), EH 27/120 Low Vib, EH 27/127 Low Vib, and EH 27/127 electric breakers.
- Restored Blow Energy — A worn or damaged striker piston causes a loss of impact force and inconsistent cycling; replacing it with 5000109197 returns the breaker to its rated breaking power for concrete, masonry, and hardscape demolition.
- Electrical Safety Alignment — Using the correct OEM striker piston maintains the internal geometry of the breaker mechanism, preventing excessive vibration or misalignment that can stress electrical components in the EH 27's motor housing.
The striker piston is the core impact element inside an electric demolition breaker. Driven by the breaker's internal reciprocating mechanism, it delivers rapid, high-force blows to the tool shank, transferring energy into the work surface to break up concrete, asphalt, or masonry. Because the striker piston operates under continuous high-impact stress, it is a primary wear component — over time, surface wear or material fatigue reduces blow energy and can cause the breaker to cycle erratically or stall entirely. Replacing a worn striker piston with the correct OEM part is essential to restoring consistent breaking performance and protecting the surrounding cylinder and tool retainer from secondary damage.
