The Wacker Neuson Compression Spring is a genuine OEM component designed for the EHB 7 series electric demolition hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a proper fit within the hammer mechanism. This spring is a critical internal component that supports consistent impact performance across the EHB 7 family of SDS-max rotary demolition hammers.
Key Features
- Genuine OEM Spring Rate: — Manufactured to the original load and deflection specifications required for correct hammer impact cycling — not a generic approximation.
- Direct Internal Fit: — Engineered to seat correctly within the EHB 7 series hammer mechanism, aligning with existing retaining geometry for straightforward installation.
- Broad EHB 7 Series Coverage: — Confirmed fitment across the EHB 7M, EHB 7/115, and EHB 7/230 electric demolition hammers, covering both 115V and 230V variants.
- Consistent Impact Energy: — A correctly spec'd compression spring maintains the striking force needed for efficient chiseling and drilling in concrete and masonry; a fatigued or broken spring leads to weak or erratic blows.
- Electrical Safety Compliance: — As a genuine OEM part used within an electric power tool, it meets the original design tolerances that contribute to safe, predictable operation of the tool's internal mechanism.
A compression spring in an SDS-max demolition hammer plays a central role in the tool's internal striking mechanism, storing and releasing energy to drive the piston and deliver repeatable impact force to the chisel or bit. When this spring fatigues, loses tension, or breaks, the hammer will produce noticeably weaker blows, inconsistent chipping action, or may stop delivering impact altogether. Replacing a worn compression spring with a correctly rated OEM part restores the hammer to its designed output and protects surrounding mechanism components from the stress of an unbalanced impact cycle.
