The Wacker Neuson is a genuine OEM Retaining Ring designed for the DPU series reversible vibratory plate compactors, covering a wide range of models including the DPU 4045H, DPU 5045H, DPU 6055, DPU 6555H, DPU 5545H, DPU 4545H, DPU 7060, and DPS 2040/2050 series. As a genuine Wacker Neuson part, the is manufactured to the exact specification of the original component, ensuring a direct drop-in fit with no guesswork. This retaining ring is a critical retention fastener that keeps internal shaft and bearing assemblies properly seated within the compactor's drive and exciter system. Sourced directly from Wacker Neuson, part is the correct replacement for any of the covered DPU models listed in the compatibility data.
Key Features
- Genuine OEM Material Grade — Manufactured from hardened spring steel to the exact tension and dimensional tolerances required for secure retention in high-vibration compactor assemblies.
- Direct Drop-In Replacement — Matches the original groove dimensions and snap engagement profile exactly, seating into the retaining groove without modification or fitting adjustments.
- Broad DPU Series Compatibility — Fits a wide range of Wacker Neuson reversible vibratory plate compactors across the DPU 4045H, DPU 5045H, DPU 5545H, DPU 4545H, DPU 6055, DPU 6555H, and DPU 7060 families, as well as DPS 2040 and DPS 2050 models.
- Maintains Shaft and Bearing Alignment — A properly seated retaining ring holds rotating components in their designed axial position, preventing lateral movement that accelerates wear on bearings and seals.
- Correct Part for High-Cycle Vibration Loads — Reversible plate compactors generate continuous high-frequency vibration; an OEM-spec retaining ring is sized and tempered to resist fatigue and loss of retention force under these sustained loads.
A retaining ring is a precision fastener that snaps into a machined groove on a shaft or inside a bore to hold rotating or sliding components — such as bearings, gears, or eccentric weights — firmly in their correct axial position. In a reversible vibratory plate compactor like the DPU series, the exciter unit operates under intense, continuous vibration, and the retaining ring prevents critical internal components from walking out of position during operation. When a retaining ring fails, becomes deformed, or is missing, bearings and rotating assemblies can shift, leading to accelerated wear, increased noise, and potential damage to the exciter housing or drive shaft.
