Boom Pivot Bushing

Boom pivot bushing (Part 53547920), used in the pivot/boom linkage assembly on Kalmar Ottawa terminal tractors and yard trucks. It’s a wear-resistant bushing that fits into the pivot mounting point where the boom or related structural arm rotates, providing a smooth bearing surface that supports movement while reducing wear and noise. Critical wear components in any heavy machinery linkage. Without a proper bushing, direct metal to metal contact at pivot points can accelerate wear, cause misalignment, introduce noise, and lead to premature failure of pins and brackets.
