WASHER SHIM-ZINC PLATED PER (JLG JL91041451)

A worn washer shim can cause loose fasteners and premature component wear. This aftermarket replacement part references the JLG catalog number JL91041451. The washer shim is a thin, flat ring used to fill gaps or adjust spacing between assembled parts. Its plain mechanical function is to distribute load evenly under a fastener head or nut. A common failure consequence is that a missing or crushed shim allows bolted joints to loosen under vibration.
