WASHER (JLG JL91364092)

A damaged washer can allow fastener loosening under vibration, leading to joint failure. During inspection, a washer's flatness and thickness affect clamp load distribution. Keeping a washer in sound condition helps maintain consistent torque retention. This aftermarket replacement part references JLG as the OE maker and cross-references part number JL91364092. The washer type provides a bearing surface for threaded fasteners and prevents galling. A common generic failure consequence is that a crushed or missing washer reduces preload, causing bolts to back out. Verify the serial number or application, then call (562) 693-7748.
