Wacker Neuson 5000098454 Washer

The Wacker Neuson Washer is a genuine OEM washer designed for the RD7 and RD10 tandem rollers and the DPU 4045H, DPU 4545H, DPU 5045H, DPU 5545H, DPU 6055, and DPU 6555H series reversible vibratory plate compactors. Sourced directly from Wacker Neuson, this replacement washer meets the same specifications as the original hardware installed at the factory. Whether you are servicing a walk-behind double-drum roller or a heavy-duty diesel reversible plate, part number ensures proper clamping load, fastener alignment, and load distribution exactly as designed. Its broad compatibility across the RD and DPU product families makes it a practical stocking item for dealers and fleet maintenance teams alike.

Key Features

• Genuine OEM Material Grade — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring correct load distribution under the high-vibration stress loads that RD and DPU machines generate during operation.
• Direct Hardware Replacement — Matches the original inside diameter, outside diameter, and thickness, so it seats correctly against mating fasteners and surfaces without shimming or adjustment.
• Broad Model Coverage — A single part number covers multiple RD7 and RD10 tandem roller variants plus the full DPU 4045H through DPU 6555H reversible vibratory plate range, simplifying parts inventory across your equipment fleet.
• Protects Mating Surfaces — Distributes fastener clamping force evenly across the joint face, preventing fretting, galling, and surface damage on aluminum and steel housings that are costly to repair.
• Vibration-Environment Rated — As a genuine OEM component, it is validated for the continuous high-frequency vibration environment of compaction equipment, where underspec washers can back off, deform, or fail prematurely.

A washer is a thin, flat plate placed under a bolt head or nut to distribute clamping force over a larger surface area, preventing the fastener from pulling through or damaging the material beneath it. In high-vibration equipment like vibratory plate compactors and tandem rollers, washers also help maintain fastener preload by resisting the micro-movement that can cause bolts to work loose during operation. When a washer deforms, corrodes, or is missing entirely, fasteners lose proper torque retention, which can lead to loose assemblies, accelerated wear on mating components, and potential mechanical failure in the field.
