The Wacker Neuson Crank Gear Complete is a genuine OEM component designed for the EH 100 series electric breakers and electric hammers. As a factory-sourced part, it is manufactured to the exact specifications required by these machines, ensuring a direct drop-in replacement with no guesswork on fit or compatibility. This part is confirmed to fit multiple EH 100 configurations, including 28x152, 28x160, and 32x160 variants across 230V and 240V models. When you need a dependable repair backed by the original equipment manufacturer, the is the correct choice.
Key Features
- OEM Gear Tooth Accuracy — Sourced directly from Wacker Neuson, this crank gear is cut and hardened to the original tooth profile, ensuring smooth meshing and consistent power transmission through the breaker mechanism.
- Direct-Fit Installation — Engineered to match the original mounting interface and gear dimensions, this assembly installs into the crank housing the same way the factory unit does — no machining or adaptation needed.
- Broad EH 100 Series Coverage — Fits a wide range of EH 100 electric breaker and electric hammer variants, including 28x152, 28x160, and 32x160 tool steel configurations across both 230V and 240V platforms.
- Sustained Impact Force Output — A correctly functioning crank gear translates motor rotation into consistent reciprocating force at the chisel. A worn or damaged gear causes erratic impact energy, tool slippage, or complete loss of breaking action.
- Genuine OEM Durability — Built from the same materials and to the same load tolerances as the original, this complete assembly is designed to handle the continuous high-cycle stress of electric demolition work without premature wear.
The crank gear is a core mechanical component inside an electric breaker or demolition hammer, responsible for converting the rotational motion of the motor into the linear, reciprocating action that drives the chisel or tool steel into concrete and masonry. It works in close coordination with the piston and striker mechanism, and its gear teeth must remain precisely formed to maintain consistent impact energy transfer. When the crank gear wears down or fails, the machine loses striking power, develops rough operation, or stops functioning entirely — making timely replacement essential to keeping the tool working at full capacity.
