PIN - COTTER - 1/8" X 1-1/4" (Komatsu KO012602)

A damaged cotter pin can allow a secured assembly to loosen during operation, risking component separation or misalignment. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO012602. A cotter pin is a simple fastener inserted through a hole to lock a clevis pin or bolt in place. Its plain mechanical function is to prevent axial movement by spreading its prongs after insertion. A concrete generic failure consequence is that a missing or broken cotter pin may lead to unintended disconnection of a linked assembly. Keeping a cotter pin in sound condition helps maintain the integrity of pinned connections under vibration. Verify the serial number or application, then call (562) 693-7748.
