Wacker Neuson 5002004928 Ret Ring Internal 80Mmx2.5Mm

The Wacker Neuson Ret Ring Internal 80Mmx2.5Mm is a genuine OEM component designed for a broad range of Wacker Neuson rammers, vibratory trench rollers, vibratory plates, and floor saws. Sourced directly from Wacker Neuson, this part carries the exact specifications required to maintain correct assembly tolerances across compatible equipment. It fits key model families including the BS65-V, BS65Y, BS650, RT560, RT820, RT820HT, DPU 2430F, DPU 2440F, DPU 2450F, DPS2040, DPS2050, APU3050e, APU2840e, APU2850e, APU2860e, APU3340e, APU3360e, APU3350e, and the DFS 90. Confirm your model number before ordering to ensure this is the correct retaining ring for your application.

Key Features

• OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact 80mm bore diameter and 2.5mm groove width specification, ensuring the ring seats fully and holds its retained component securely without play.
• Drop-In Groove Fit — Designed to snap directly into the corresponding internal groove with standard circlip pliers — no machining, sizing, or adaptation needed.
• Broad Model Coverage — A single part number covers vibratory rammers (BS65-V, BS65Y, BS650), trench rollers (RT560, RT820, RT820HT), reversible and single-direction vibratory plates (DPU and DPS series), electric plates (APU series), and the DFS 90 floor saw.
• Retains Critical Rotating Components — A correctly fitted internal retaining ring prevents axial movement of shafts, bearings, and drive components; a failed or worn ring allows components to walk out of position, causing rapid wear or mechanical failure.
• Genuine OEM Part — Supplied by Wacker Neuson as part 5002004928, this is not a substitute or equivalent — it is the same ring used in original production assemblies.

An internal retaining ring — also called a circlip — is a fastening device that fits into a machined groove on the inside of a bore to prevent a shaft, bearing, or other component from moving axially. In compaction and cutting equipment like vibratory rammers and trench rollers, these rings bear constant cyclic loading and must maintain their seating to keep drive and exciter assemblies properly aligned. When an internal retaining ring wears, deforms, or dislodges, the component it retains can shift under load, accelerating wear on surrounding parts and potentially causing a more significant mechanical failure.
