The Wacker Neuson Piston is a genuine OEM component designed for the EHB 7M, EHB 7/115, and EHB 7/230 series electric demolition and rotary hammers. As a direct Wacker Neuson OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit within the hammer's internal percussion mechanism. This piston is compatible across the EHB 7 family, covering both 115V and 230V configurations, making it the right choice whether you are servicing a single-voltage or dual-voltage unit. Keep part number on hand to minimize disruption when scheduled maintenance or an unexpected failure requires an internal rebuild.
Key Features
- Genuine OEM Precision Tolerancing — Manufactured to exact dimensional specs for the EHB 7 percussion chamber, ensuring correct stroke length and impact energy delivery.
- Drop-In Internal Fit — Engineered to seat directly into the EHB 7 hammer housing with the same profile as the original, supporting a straightforward rebuild without custom fitting.
- Broad EHB 7 Family Coverage — Fits the EHB 7M, EHB 7/115, and EHB 7/230 models, covering SDS-max electric drilling and chiseling hammers in both 115V and 230V variants.
- Restored Impact Performance — A worn or damaged piston reduces blow energy and causes inconsistent chiseling action; replacing it with part 5000104215 restores full percussion output.
- Fuel System Safety Compliance — Using the correct OEM piston maintains the mechanical integrity of the percussion assembly, preventing secondary damage to surrounding components such as the cylinder and drive mechanism.
The piston is the core reciprocating component inside an electric demolition hammer's percussion mechanism. It travels back and forth at high speed within the cylinder, generating the impact force that drives the chisel or drill bit into the material. When the piston wears, cracks, or loses its sealing surface, blow energy drops noticeably — the hammer feels weak, delivers inconsistent strikes, or may stop producing impact altogether. Replacing the piston with a correctly specified part restores the full mechanical output the EHB 7 series is built to deliver.
