Key Features

• Genuine OEM Material Integrity — Manufactured to the same hardness and dimensional tolerances as the original washer, ensuring correct load distribution and surface protection at the fastening point.
• Drop-In Replacement — Matches the original bore diameter, outer diameter, and thickness so it seats correctly without rework or shimming.
• Broad Compaction Equipment Fitment — Compatible with Wacker Neuson RD18, RD24, RD27, RD28, RD40, and RD45 tandem rollers and RC50, RC70, and RC110 single drum soil compactors, including CAB, ROPS, DPF, and electric variants.
• Protects Mating Surfaces — A correctly sized washer distributes clamp load evenly across the joint, preventing fastener pull-through, surface galling, and loosening under vibration — all real concerns on compaction equipment.
• Sourced Direct from Wacker Neuson — Genuine OEM part number 5100013521, not a substitute — so you can order with confidence that it matches the original part specification.

A washer acts as a load-spreading interface between a fastener — such as a bolt or nut — and the surface it clamps against. On compaction equipment like tandem rollers and soil compactors, fasteners are subjected to constant vibration and dynamic stress, which makes the washer's role especially important: it prevents the fastener head from digging into or deforming the mating surface, maintains consistent clamping force, and helps the joint resist loosening over time. When a washer is worn, deformed, or missing, the fastener loses its ability to hold proper torque, which can lead to joint movement, accelerated wear on surrounding components, and potential mechanical failure in critical assemblies.
