Boom pivot bushing (Part 53504759), used in the pivot/boom linkage assemblies of terminal tractors and yard trucks. It’s a wear resistant precision bushing that fits into a pivot joint, typically where a boom, arm, or structural linkage rotates, providing a smooth bearing surface and reducing wear on metal parts under load and movement. When the boom or linkage moves, this bushing sits between the pivot pin and the housing to provide a stable surface. Works with pin part number
