JL4272421: A damaged retaining ring can allow assembled components to separate during operation, leading to mechanical failure. The JLG catalog reference for this aftermarket replacement part is JL4272421. This gear ring functions as a retaining ring, securing components in a fixed position on a shaft or within a bore.
