Wacker Neuson 5100011695 U-Washer

The Wacker Neuson U-Washer is a genuine OEM component designed for the RD18, RD24, RD27, RD28, RD40, and RD45 series tandem rollers. Sourced directly from Wacker Neuson, this part meets the exact tolerances and material specifications used in original production, ensuring a correct, trouble-free installation. It fits an extensive range of RD series tandem roller configurations — including standard, C, O, DPF, and electric variants — making it a widely applicable service part for fleet operators and dealers alike.

Key Features

• OEM Material Consistency — Manufactured to the same hardness and dimensional tolerances as the original, so load distribution and seating behavior match what the roller was built with.
• Drop-In Installation — Matches the original mounting geometry exactly, fitting into the existing fastener stack without modification or adjustment.
• Broad RD Series Coverage — Compatible with RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families, including standard, C, O, DPF, and electric (e) variants across multiple serial number ranges.
• Maintains Clamping Integrity — A correctly seated U-Washer distributes fastener load evenly across the mating surface; a worn or deformed washer can lead to fastener loosening, vibration-related damage, and premature wear on surrounding components.
• Genuine Wacker Neuson OEM Part — Supplied as an authorized replacement, carrying the same part number 5100011695 referenced in Wacker Neuson service documentation for straightforward parts lookup and ordering.

A U-Washer is a load-spreading fastener component used to distribute the clamping force of a bolt or nut evenly across a wider surface area, preventing the fastener from pulling through or deforming the mating material under vibration and operational stress. On tandem rollers like the RD series, where high-cycle vibration is constant during compaction work, washers play a critical role in keeping fastener assemblies tight and intact. When a U-Washer becomes deformed, cracked, or undersized due to wear, it compromises the clamping joint — potentially causing loosening, misalignment, or accelerated wear in the connected assembly.
