The Wacker Neuson Gear is a genuine OEM component designed for the EHB 10 and EHB 11 series electric demolition hammers. This is a direct-from-manufacturer replacement sourced to the original specification, ensuring the internal drive system operates exactly as engineered. Confirmed fitment spans a wide range of EHB 10 and EHB 11 variants across 110V, 115V, 127V, 200V, 230V, 240V, and 250V configurations, including SDS-max and spline chuck models. When you need a verified OEM part to restore full hammer performance, the is the correct choice.
Key Features
- OEM-Specified Gear Geometry — Manufactured to the original tooth profile and material grade, maintaining correct torque transfer through the hammer's drive train without slippage or premature wear.
- Drop-In Internal Replacement — Engineered to the original dimensions, this gear installs directly into the EHB hammer gearbox without modification to housings or adjacent components.
- Broad EHB Series Fitment — Covers EHB 10 and EHB 11 series models across multiple voltage configurations (110V through 250V), SDS-max, spline, and 19x82.5 chuck variants.
- Restores Full Rotary and Chiseling Function — A worn or damaged gear causes loss of rotation, erratic chiseling action, or complete drive failure; replacing it with the correct OEM part brings the hammer back to full working capacity.
- Genuine Wacker Neuson OEM Part — Supplied under part number 5000043350 directly within the Wacker Neuson OEM parts network, with traceability back to the original equipment specification.
The gear in an electric rotary demolition hammer is a core element of the internal drive train, transmitting motor torque to the hammering and rotation mechanism. It works in coordination with adjacent gears and the piston assembly to convert electrical power into the percussive and rotary force needed to drill or chisel through concrete and masonry. When this gear wears down or fails — typically through chipped teeth, surface fatigue, or seizure — the hammer loses its ability to rotate the bit, deliver impact energy, or both, often resulting in grinding noise and a complete loss of productivity until the part is replaced.
