Wacker Neuson 5002003023 Internal Retaining Ring 72mm x 2.5mm

The Wacker Neuson Internal Retaining Ring 72mm x 2.5mm is a genuine OEM component designed for a wide range of Wacker Neuson vibratory rammers, including the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS50-4s, BS60-4s, BS60-4As, BS70-4As, DS70, DS720, and many more models in the BS and DS series. As a direct Wacker Neuson OEM part, is manufactured to the same specification as the original component, ensuring a drop-in fit with no guesswork. This ring is stocked to support the full breadth of the BS50, BS60, and BS70 rammer families across two-cycle, oil-injected, and four-stroke configurations.

Key Features

• OEM Snap Geometry: — Stamped to the exact 72mm bore diameter and 2.5mm groove width specified for Wacker Neuson rammer assemblies, so the ring seats flush and holds under compaction loads.
• Direct Drop-In Installation: — Installs into the same groove as the original using a standard internal snap-ring plier set — no machining, shimming, or adapting required.
• Broad Rammer Compatibility: — Fits BS50, BS60, BS70, DS70, and DS720 series machines across two-cycle, oil-injected, and four-stroke variants, covering both US EPA and EU configurations.
• Retains Critical Shaft and Bearing Components: — Keeps internal rotating or reciprocating components positionally locked, preventing axial drift that leads to accelerated bearing and bore wear.
• Genuine Wacker Neuson OEM Quality: — Sourced through authorized Wacker Neuson supply channels, this ring meets the material hardness and spring-rate requirements of the original factory part.

An internal retaining ring — also called an internal snap ring or circlip — is a precision-stamped fastener that fits into a machined groove inside a bore to lock a shaft, bearing, or pin in its correct axial position. In a vibratory rammer, these rings prevent the reciprocating drive components from shifting along their axis during the high-frequency impact cycles the machine produces. When a retaining ring becomes worn, cracked, or dislodged, the components it holds can shift out of position, causing uneven bearing loading, increased vibration, and eventually catastrophic damage to the bore or drive assembly. Replacing a failed or suspect ring promptly with the correct OEM part — verified by part number 5002003023 — restores proper component alignment and protects the surrounding assembly.
