Key Features

• Genuine OEM Construction — Manufactured to the same material grade and dimensional tolerances as the original washer, ensuring correct load distribution and clamping force at the fastened joint.
• Direct Drop-In Replacement — Matches the original bore diameter, outer diameter, and thickness so it seats correctly against mating hardware without rework or shimming.
• Wide Compactor Fleet Coverage — Fits RD24-100, RD27-120, RD28-120, RD40-130, RD45-140 Tandem Rollers and RC50, RC70, RC110 Single Drum Soil Compactors, including C, O, US, ROPS, and CAB variants.
• Protects Fastener Integrity — A properly functioning washer spreads clamp load evenly, preventing fastener pull-through, surface galling, and premature loosening under vibration-heavy compaction cycles.
• Verified Part Number — Order with confidence using Wacker Neuson part number 5100012941, cross-referenced across multiple machine serial number ranges in the fitment list above.

A washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. By spreading the clamping force over a wider area, it prevents the fastener from digging into or deforming softer materials, and helps maintain consistent torque retention even under continuous vibration. On heavy compaction equipment like tandem rollers and soil compactors, where vibration is constant and high, a worn, missing, or incorrect washer can lead to fastener loosening, accelerated wear of surrounding components, and eventual structural failure at the joint. Replacing a damaged washer promptly with the correct OEM part keeps the assembly torqued to spec and protects the hardware around it.
