The Wacker Neuson Cylinder Housing is a genuine OEM component designed for the EH 9 BL and EH 9 BLM series electric demolition breakers. As a direct OEM replacement, this part is produced to the same specifications as the original, ensuring correct fit and function across all covered EH 9 configurations. Compatible with both 115V and 230V variants — including WMI-equipped models — the covers a wide range of EH 9 BL and EH 9 BLM machines. When your breaker's cylinder housing is worn, cracked, or damaged, replacing it with the correct Wacker Neuson part restores the structural integrity and performance the tool was built to deliver.
Key Features
- OEM-Matched Housing Dimensions — Cast and machined to original tolerances, ensuring the piston and internal components seat and travel correctly within the cylinder bore.
- Direct-Fit Replacement — Installs in place of the original housing using existing mounting points and fastener patterns; no reworking of adjacent components required.
- Broad EH 9 Series Coverage — Fits EH 9 BL and EH 9 BLM models in both 115V and 230V configurations, including standard, WMI, and SUL variants.
- Structural Integrity Restored — A failed or cracked cylinder housing allows pressure loss and lateral play in the striking mechanism; replacing it brings impact energy and cycle consistency back to spec.
- Electrical Safety Compliance — The housing forms part of the breaker's internal isolation and containment structure; using a correctly spec'd OEM part maintains the tool's rated electrical safety envelope.
The cylinder housing is the core structural shell of the electric breaker's striking assembly. It contains the reciprocating piston, guides the impact mechanism through each strike cycle, and maintains the internal pressure conditions necessary for consistent chisel energy. When the housing becomes cracked, worn, or dimensionally out of spec, the piston loses its guided travel path — leading to reduced impact force, increased vibration, and accelerated wear on surrounding components. Replacing the housing with a correctly dimensioned part is essential to restoring full breaker performance and preventing secondary damage to the tool's internal drive train.
