The Wacker Neuson Crankcase Complete is a genuine OEM component designed for the EH 100 series electric breakers and electric hammers. Sourced directly from Wacker Neuson, this crankcase assembly meets the exact specifications of the original part it replaces, covering multiple EH 100 configurations including 28x152, 28x160, and 32x160 variants. Verified fitment spans both 230V and 240V models, making this the correct choice when rebuilding or repairing EH 100 breakers across a range of regional specifications.
Key Features
- OEM Structural Integrity — Cast and machined to original tolerances, ensuring internal components seat correctly and crankcase sealing surfaces remain true to spec.
- Direct-Fit Assembly — Designed as a complete crankcase unit, this drop-in replacement aligns with existing mounting points and internal bore dimensions without rework.
- Broad EH 100 Coverage — Confirmed fitment across EH 100/230 and EH 100/240 electric breaker and electric hammer models in 28x152, 28x160, and 32x160 configurations.
- Restored Impact Performance — A sound crankcase maintains proper compression and piston travel, directly supporting consistent blow energy output during breaking operations.
- Leak and Contamination Prevention — Genuine OEM material and surface finish on sealing surfaces help prevent lubricant loss and ingress of debris that can accelerate internal wear.
The crankcase is the structural core of an electric breaker, housing the piston, cylinder bore, and internal drive components that generate the machine's hammering action. It maintains the sealed environment necessary for lubrication to circulate correctly and for impact energy to transfer efficiently through the tool steel. When a crankcase cracks, warps, or develops damaged sealing surfaces, compression is lost, lubricant escapes, and internal components are exposed to contamination — leading to rapid wear and loss of breaking force. Replacing it with a complete genuine OEM assembly restores the structural foundation the rest of the breaker depends on.
