Wacker Neuson 5100023077 U-Washer

The Wacker Neuson U-Washer is a genuine OEM component designed for the RC50, RC70, and RD-series single drum soil compactors, including RC50, RC50p, RC70, RC70p, RC70vo, RD24e-100, and RD28e-120 models. Sourced directly from Wacker Neuson, this U-Washer meets the exact dimensional and material standards of the original part. It covers an extensive range of RC and RD compactor configurations, including CAB, ROPS, DPF, and electric variants, making it a versatile service part for mixed fleets. When it's time to restore your machine to proper working condition, the delivers the fit and function you need.

Key Features

• Genuine OEM Material Integrity — Manufactured to Wacker Neuson's original hardness and dimensional tolerances, ensuring correct load distribution and seating performance specific to this washer application.
• Drop-In Installation — Matches the original U-profile geometry exactly, seating flush against mating surfaces without adjustment or rework during reassembly.
• Broad RC and RD Series Coverage — Fits RC50, RC50p, RC70, RC70p, and RC70vo compactors across multiple build variants (CAB, ROPS, DPF), plus RD24e-100 and RD28e-120 electric roller models.
• Maintains Proper Clamping Force — A correctly seated U-Washer distributes fastener load evenly across the joint face; a worn or deformed washer allows fastener loosening, vibration-related fatigue, and premature component failure in high-cycle compactor operation.

A U-Washer is a curved or channel-profile washer used to distribute the clamping load of a fastener across a wider contact area, particularly where surfaces are uneven, recessed, or subject to high vibration. On soil compactors like the RC and RD series, components experience constant vibration loads during operation, making proper washer geometry critical to keeping fastened assemblies secure over time. When a U-Washer deforms or wears, fastener preload is lost, which can lead to loosening hardware, accelerated wear on surrounding components, and potential structural issues that interrupt work on site.
