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 exact specification of the original, ensuring a correct drop-in fit within the hammer mechanism. Sourcing a genuine Wacker Neuson Compression Spring means you can trust the spring rate and material grade match what the machine was built with. Confirmed fitment covers the EHB 7/115 and EHB 7/230 variants across multiple machine configurations in the EHB 7 family.
Key Features
- Correct Spring Rate for SDS-max Hammer Mechanisms — manufactured to OEM spring-rate specification, ensuring the internal striking mechanism cycles with the force and consistency the EHB 7 series requires.
- Genuine OEM Part — sourced directly from Wacker Neuson, this is the same Compression Spring installed at the factory, not an approximation.
- Direct Replacement for EHB 7 Series Hammers — confirmed fitment for EHB 7M, EHB 7/115, and EHB 7/230 electric demolition hammers; installs in place of the original with no modification to the surrounding components.
- Restores Full Impact Performance — a worn or fatigued compression spring causes inconsistent blows, reduced chiseling force, and increased wear on adjacent internal parts; replacing it promptly keeps the hammer delivering full rated impact energy.
- Electrical Safety Relevance — correct internal spring tension is critical in electric demolition hammers to maintain proper component engagement and prevent erratic operation that could create a hazard for the operator.
A compression spring inside an electric demolition hammer plays a key role in the internal impact mechanism, storing and releasing energy to drive the piston or striker that delivers blows to the tool bit. When this spring weakens or breaks, the hammer may lose striking force, cycle irregularly, or stop delivering impacts altogether — even while the motor continues to run. Replacing a worn Compression Spring with a genuine OEM part restores the correct internal dynamics of the EHB 7 series and brings the hammer back to its full chiseling and drilling performance.
