The Wacker Neuson is a genuine OEM Gear Case Flange Complete designed for the EH 25, EH 50, EH 70, and EH 75 series electric breakers. As a factory-authorized component, this part is manufactured to the exact tolerances and specifications required for proper gear case assembly and sealing across the full range of compatible Wacker Neuson electric hammers. Covering both 115V and 230/240V variants as well as multiple chisel shank configurations, the is the correct service replacement for a wide spread of EH series models used on commercial demolition and breaking applications.
Key Features
- OEM Gear Case Integrity — Manufactured by Wacker Neuson to the precise flange geometry and material specification required to maintain a correctly sealed and aligned gear case housing.
- Direct-Fit Flange Assembly — Supplied as a complete flange assembly, this part installs directly onto the gear case housing without additional machining or fitting work.
- Broad EH Series Coverage — Compatible with EH 25, EH 50, EH 70, and EH 75 series electric breakers across 115V, 120V, 230V, and 240V configurations and multiple chisel shank formats.
- Protects Internal Drive Components — A correctly seated gear case flange maintains proper lubrication containment and bearing alignment; a failed or damaged flange allows lubricant loss and accelerates wear on internal drive components.
- Electrical Safety Compliance — Using the correct OEM flange on electric breakers ensures the gear case enclosure maintains its designed insulation and ingress protection, supporting safe operation on powered demolition tools.
The gear case flange on an electric breaker serves as the structural and sealing interface between the gear case housing and the rest of the drive assembly. It keeps internal lubricant contained, supports bearing surfaces, and maintains the alignment of the reciprocating mechanism that delivers impact energy to the chisel. When the flange is cracked, worn, or improperly seated, lubricant escapes, internal components run dry, and the breaker's impact performance degrades rapidly — often leading to more extensive gear case damage if not addressed promptly.
