A lockwasher is a hardened fastening component placed beneath a nut or bolt head to resist loosening caused by vibration and dynamic loading. On a tandem vibratory roller like the RD27, drivetrain, frame, and drum assembly fasteners are exposed to constant vibration during compaction passes, creating conditions that cause standard fasteners to gradually back out over time. A lockwasher bites into both the fastener bearing surface and the mating component, maintaining clamp force and keeping critical connections secure. When a lockwasher becomes flattened, cracked, or corroded, it loses its ability to grip, which can allow fasteners to loosen and lead to mechanical play or component damage in the affected assembly.
