Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact thickness and bore tolerances, ensuring proper load distribution and seating specific to this washer application.
- Drop-In Replacement — Installs directly in place of the original hardware with no rework to surrounding components or fastener assemblies.
- Broad RD Series Fitment — Compatible with RD40-130 and RD45-140 tandem rollers across standard, C, O, DPF, and US-market configurations, covering a wide production range.
- Protects Mating Surfaces — A correctly fitted washer distributes clamping force evenly across fastener joints, preventing surface damage, fastener loosening, and premature wear to housings or brackets.
A washer serves as a critical load-distributing component placed beneath a bolt head or nut to spread clamping force across a wider surface area. This prevents the fastener from pulling through or damaging the material it secures, and helps maintain consistent clamping pressure over time. When a washer is missing, deformed, or worn, fasteners can work loose under vibration — a common stress condition on compaction equipment — leading to component movement, accelerated wear, and potential structural loosening in assemblies where secure fastening is essential to safe, consistent roller operation.
