The Wacker Neuson Compression Spring is a genuine OEM component designed for the EH 9 BLM and EHB 11 BLM series electric breakers and hammers. This is a direct OEM replacement sourced through authorized Wacker Neuson supply channels, ensuring it meets the original engineering specifications for these machines. Compatible with both 115V and 230V variants across the EH 9 BLM and EHB 11 BLM model families, this spring is the correct part for technicians servicing these electric demolition tools. Always verify your machine's model number before ordering to confirm fitment.
Key Features
- OEM Spring Tension Integrity — Manufactured to the original compression load and travel specification, ensuring the internal striking mechanism cycles at the correct rate and force.
- Drop-In Internal Fit — Engineered to seat correctly within the hammer mechanism housing, requiring no modification to the spring cavity or retaining components during installation.
- Broad EH / EHB Series Coverage — Fits multiple variants of the EH 9 BLM and EHB 11 BLM electric breaker and hammer families, including 115V and 230V configurations.
- Sustained Impact Consistency — A properly functioning compression spring maintains the percussion cycle that drives chisel and bit penetration; a worn or fatigued spring causes reduced impact energy and erratic chiseling performance.
- Genuine OEM Part — Supplied as a genuine Wacker Neuson replacement component, carrying the same part number — 5000109299 — used in original factory assembly.
The compression spring in an electric breaker or demolition hammer is a core element of the reciprocating percussion mechanism. It stores and releases mechanical energy with each stroke cycle, driving the striker or piston to deliver consistent impact force to the tool bit. When this spring weakens, loses tension, or breaks, the hammer loses striking power, may cycle irregularly, or can stop functioning altogether — making timely replacement critical to maintaining productive chiseling or breaking output.
