Wacker Neuson 5000220384 Retaining Ring

The Wacker Neuson Retaining Ring is a genuine OEM component designed for the DPU4045, DPU4545, DPU5545, DPU6555, and BPU4045 and BPU5545 series reversible vibratory plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the exact tolerances required to maintain proper shaft and component retention within the compactor's drivetrain assembly. This retaining ring fits an extensive range of DPU and BPU model variants — including Heh, Hech, He, Hec, Heap, Hesh, Yeh, and Yehzf suffix configurations — covering both US and international spec machines. Confirm your model number before ordering to ensure correct application.

Key Features

• Genuine OEM Retention Geometry — Manufactured to Wacker Neuson's exact ring groove dimensions, ensuring the clip seats fully and holds under vibratory load without creep or displacement.
• Broad DPU and BPU Series Coverage — Fits DPU4045, DPU4545, DPU5545, DPU6555, BPU4045, and BPU5545 series reversible vibratory plate compactors across multiple suffix variants and regional specifications.
• Drop-In Replacement — Matches the original ring profile for direct installation into the existing groove — no filing, shimming, or rework required.
• Drivetrain Integrity Under Sustained Vibration — A correctly seated retaining ring keeps rotating and reciprocating components positively located; a worn or missing ring allows axial play that accelerates bearing and shaft wear.
• OEM Part Number Traceability — Sourced directly from Wacker Neuson, part number 5000220384 cross-references cleanly against all listed machine numbers for confident ordering.

A retaining ring — also known as a snap ring or circlip — is a fastening device that seats into a machined groove on a shaft or inside a bore to prevent lateral movement of adjacent components such as bearings, gears, or sleeves. In a reversible vibratory plate compactor, these rings are subjected to constant vibration and cyclic loading, making material integrity and proper seating critical. When a retaining ring fails, becomes deformed, or is missing entirely, the components it locates can shift axially, leading to accelerated wear on bearings, increased vibration noise, and — in severe cases — drivetrain damage that requires significantly more extensive repair.
