The Wacker Neuson Locking Ring is a genuine OEM component designed for the EHB 7 series electric rotary demolition hammers, including the EHB 7M, EHB 7/115, and EHB 7/230 models. Sourced directly from Wacker Neuson, this locking ring matches the original production specification for a drop-in fit with no guesswork on compatibility. It serves as a critical retention component within the hammer's internal assembly, making it an essential part for any service or rebuild on these machines. Whether you're restoring a worn tool or completing a scheduled overhaul, part number keeps your EHB 7 series hammer running as intended.
Key Features
- Genuine OEM Retention Integrity — Manufactured to the exact dimensional tolerances required for secure locking function inside the EHB 7 series hammer mechanism, ensuring the ring seats and holds correctly under repeated impact loads.
- Direct-Fit Replacement — Replaces the original locking ring on EHB 7M, EHB 7/115, and EHB 7/230 models; installs in the same position as the factory part with no modification to surrounding components.
- EHB 7 Series Compatibility — Confirmed fitment across the EHB 7M, EHB 7/115, and EHB 7/230 SDS-max electric demolition hammers, covering both 115V and 230V variants.
- Sustained Impact Performance — A correctly fitted locking ring maintains the alignment and retention of internal drive components; a worn or failed ring can cause play, vibration, or loss of striking force in the hammer.
- Verified OEM Part Number — Cross-reference 5000104175 against your tool's parts diagram before ordering to confirm position and application within the assembly.
A locking ring is a precision retention component used to secure rotating or reciprocating assemblies in place within a tool's housing. In an SDS-max rotary demolition hammer like the EHB 7 series, it prevents axial movement of internal shaft or barrel components, keeping everything correctly positioned during high-frequency impact operation. When a locking ring wears, cracks, or loses its retention grip, internal parts can shift under load — leading to increased vibration, reduced striking efficiency, and accelerated wear on surrounding components.
