Wacker Neuson 5100012230 Washer — RD40-130 & RD45-140 Series Tandem Rollers

The Wacker Neuson Washer is a genuine OEM Washer designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, O, and.3 variants across both US and international configurations. As a direct factory replacement, part is produced to the same specifications as the original component, ensuring correct fit and function without guesswork. This Washer is compatible across a broad range of RD-series roller models, making it a reliable choice for fleet operators and service technicians working across multiple machine variants. Sourcing a genuine OEM part means you get the exact geometry and material grade Wacker Neuson engineered into these machines from the start.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's original material and dimensional spec, so seating, load distribution, and surface finish match the factory-installed component exactly.
• Direct Drop-In Replacement — Designed to install in the same position as the original, with no modification to fasteners, mating surfaces, or adjacent hardware required.
• Broad RD-Series Compatibility — Fits RD40-130 and RD45-140 tandem rollers in standard, C (cab), O (open), and .3 configurations, covering both US and international model series.
• Correct Load Bearing and Surface Protection — A properly sized washer distributes clamping force evenly across the joint, preventing fastener pull-through, surface galling, and premature loosening under continuous vibration loads typical of compaction equipment.
• Genuine Wacker Neuson Part — Sourced directly through the OEM supply chain under part number 5100012230, giving you traceability and confidence in part authenticity.

A washer serves as a load-spreading interface between a fastener and the surface it bears against, ensuring that tightening force is distributed evenly rather than concentrated at a single point. On vibratory compaction equipment like the RD40-130 and RD45-140 tandem rollers, washers are subjected to constant vibration and mechanical stress, making correct sizing and material grade critical to joint integrity. When a washer is worn, deformed, or missing, fasteners can loosen progressively, leading to component movement, accelerated wear on mating parts, and potential fastener failure.
