Part 540-086 is a replacement swivel washer used in the pivot mechanism of airless side stripers and related accessories. This washer reduces friction between moving parts, allowing the side striper arm to swing smoothly and maintain consistent line width. When the original washer becomes worn, cracked, or flattened, replacement restores precise movement and prevents scoring of the pivot surfaces.

The 540-086 swivel washer is a direct replacement component for the pivot joint on airless side striper accessories. It acts as a low‑friction bearing surface between the stationary frame and the swinging arm, enabling the striper to glide laterally when positioning lines near curbs or obstacles. Manufactured from wear‑resistant polymer, this washer resists compression and maintains its thickness over many cycles. A worn or deformed washer introduces play in the arm, causing inconsistent line spacing or unwanted movement during operation. Replacing it restores the original tolerances and ensures the side striper tracks accurately. The washer is designed for tool‑free installation and fits the factory pivot bolt without modification. Regular inspection during accessory maintenance helps identify flattening or cracking before it affects striping quality.
