The Wacker Neuson Crank Gear is a genuine OEM component designed for the EHB 11 BL and EHB 11 BLM series electric demolition hammers, covering both 115V and 230V configurations. As a direct factory replacement, this part is sourced and validated to Wacker Neuson's original engineering specifications, ensuring it integrates correctly with the hammer's internal drive mechanism. Compatibility spans the full EHB 11 BL family, including BL, BLM, and BLS variants across standard, SDS-max, spline, and specialty market configurations. Verifying your model number against part number before ordering is the best way to confirm a direct fit.
Key Features
- Genuine OEM Gear Geometry — Machined to the exact tooth profile and pitch of the original Wacker Neuson crank gear, ensuring correct mesh with mating drive components inside the EHB 11 series hammer mechanism.
- Drop-In Replacement for EHB 11 BL and BLM Series — Fits both 115V and 230V variants including BL, BLM, and BLS configurations, with no adaptation needed to the surrounding gear train or housing.
- Broad EHB 11 Family Coverage — Covers a wide range of EHB 11 models across SDS-max, spline, and standard chuck configurations, making it a high-confidence choice for service shops stocking parts for multiple EHB 11 units.
- Sustained Impact Delivery — A correctly functioning crank gear converts motor rotation into the reciprocating impact stroke that drives the tool bit. Wear or failure in this gear results in lost striking power, irregular impact rhythm, or complete loss of hammering action.
- Drive Train Integrity — In an electric demolition hammer, gear fatigue or tooth damage can propagate stress to adjacent components. Replacing with a genuine OEM crank gear restores proper load distribution across the drive assembly.
The crank gear is a core element of the electric breaker's impact drive system. It translates the rotational output of the motor into the linear, reciprocating motion that powers each hammer blow — making it fundamental to the tool's ability to break concrete, chip masonry, or drive chiseling attachments. When the crank gear wears, chips, or fails, the tool loses striking consistency and may become inoperable. Replacing this component at the first sign of reduced impact performance helps restore full function and protects the surrounding drive train from secondary damage.
