The Wacker Neuson Gear Case Flange is a genuine OEM component designed for EH 23 and EH 27 series electric demolition breakers. As a direct factory replacement, it restores the structural integrity of the gear case assembly on models including the EH 23/110/15, EH 23/230, EH 23/110/22, EH 27/115, and EH 27/127. Sourced directly from Wacker Neuson, part meets the same specifications as the original and installs without adaptation. Whether you're servicing a 110V, 115V, or 230V breaker variant, this flange covers the full range of EH 23 and EH 27 configurations.
Key Features
- Genuine OEM Structural Tolerancing — Manufactured to exact dimensional specs so the flange seats flush against the gear case housing, maintaining correct alignment of internal drive components.
- Direct-Fit Replacement — Engineered to match the original mounting pattern and interface geometry, fitting in place of the factory flange with no rework to the housing or adjacent parts.
- Broad EH Series Coverage — Compatible with multiple EH 23 and EH 27 configurations, including 110V, 115V, and 230V variants across a range of shank sizes and machine numbers.
- Preserves Drive Train Efficiency — A correctly seated gear case flange keeps the internal gear set properly enclosed and aligned, maintaining the full impact energy delivery the breaker is rated for.
- Electrical Safety Compliance — As a structural housing component on an electric breaker, a correctly fitted OEM flange helps preserve the enclosure integrity that protects internal electrical components from contamination and contact hazards.
The gear case flange is a structural housing component that closes and seals the gear case assembly on an electric demolition breaker. It holds the internal gear set in correct positional alignment, ensuring that rotational motion from the motor is efficiently converted into the reciprocating impact force that drives the chisel or shank. When the flange is cracked, warped, or improperly seated, the gear case loses its rigid reference point — leading to accelerated gear wear, loss of impact energy, and potential ingress of debris into the drivetrain. Replacing a damaged flange promptly protects the surrounding components and keeps the breaker performing at full rated output.
