The Wacker Neuson Gear is a genuine OEM component designed for the EH 100/240 and EH 100/230 series electric breakers and demolition hammers. As a direct OEM part sourced through Wacker Neuson's authorized supply chain, the meets the exact tolerancing and material specifications required for this demolition equipment family. This gear is confirmed for use across the EH 100 series, including 28x152, 28x160, and 32x160 chisel configurations, covering both US and international voltage variants.
Key Features
- OEM-Grade Tooth Profile and Material Spec — Manufactured to Wacker Neuson's exact gear geometry and hardness specifications, ensuring proper mesh, load transfer, and service life within the EH 100 drive train.
- Drop-In Compatibility for EH 100 Series Electric Breakers — Engineered to install directly into the EH 100 gear housing with correct shaft engagement and bearing interfaces, eliminating the need for machining or adjustment.
- Broad EH 100 Fitment Coverage — Fits EH 100/240 and EH 100/230 variants across multiple chisel sizes (28x152, 28x160, 32x160), including both US-spec and Brazil-spec electric hammer configurations.
- Sustained Impact Power Delivery — A correctly functioning gear transfers motor torque into consistent hammer blows; a worn or chipped gear leads to erratic impact rhythm, increased vibration, and accelerated wear on adjoining drivetrain components.
- Electrical Safety Alignment — Using the correct OEM gear maintains proper internal clearances within the electric breaker housing, helping prevent contact between rotating components and electrical assemblies inside the tool.
The gear in an electric breaker forms a critical link in the power transmission path between the motor and the reciprocating piston mechanism that drives the chisel. It converts rotational motor speed into the timed mechanical action needed to deliver consistent, high-energy hammer blows to concrete, masonry, and similar materials. When this gear wears, chips, or fails, the breaker loses striking force, produces abnormal noise and vibration, and can ultimately seize — taking the tool out of service and risking damage to surrounding drivetrain components.
