The Wacker Neuson Retainer is a genuine OEM component designed for the EHB 7M, EHB 7/115, and EHB 7/230 series electric demolition and rotary hammers. As a direct OEM part, the is manufactured to the same specifications as the original, ensuring a proper fit within the tool's internal assembly. This retainer is compatible across multiple EHB 7 configurations, including both 115V and 230V variants. Confirm your model number before ordering to ensure correct application.
Key Features
- Genuine OEM Construction: — Manufactured to the original dimensional and material specifications, ensuring the retainer seats and functions exactly as designed within the EHB 7 hammer assembly.
- Direct Internal Fit: — Engineered to drop into place within the existing hammer housing without rework, maintaining the correct positional alignment of retained components.
- Broad EHB 7 Series Compatibility: — Confirmed fitment across the EHB 7M, EHB 7/115, and EHB 7/230 electric SDS-max demolition and rotary hammer models.
- Maintains Drive Train Integrity: — A correctly seated retainer keeps internal components properly positioned under the high-impact cycling loads typical of SDS-max demolition work; a worn or missing retainer can allow unwanted movement and accelerate wear on surrounding parts.
- Verified OEM Part Number: — Part number 5000104257 is the factory-assigned reference for this retainer across the EHB 7 platform, reducing the risk of fitment errors when sourcing replacements.
A retainer is an internal fastening or locating component that holds a specific part — such as a bearing, pin, or drive element — in its correct position within the tool's housing or mechanism. In a high-cycle SDS-max electric hammer like the EHB 7 series, internal components are subjected to repeated percussion forces, making secure retention critical to consistent performance. When a retainer becomes worn, cracked, or dislodged, it can allow internal parts to shift under load, leading to increased vibration, accelerated component wear, or loss of function in the hammer's striking or rotation mechanism.
