SPRING (Komatsu KO3EB-15-28371)

KO3EB-15-28371: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3EB-15-28371. The retaining ring functions as a fastener that holds components in a fixed position on a shaft or in a bore. Its primary mechanical role is to seat into a groove and resist axial movement.
