WASHER (JLG JL91474100)

A damaged washer can allow fastener loosening under vibration, leading to component misalignment. During inspection, a washer's condition affects clamping force and joint integrity. Keeping a washer in sound condition helps maintain consistent preload on bolted connections. This aftermarket replacement part references JLG catalog number JL91474100. The part type is a hardware washer, which distributes load and prevents galling between a fastener head and the mating surface. A common failure consequence is that a crushed or missing washer reduces clamping force, risking joint separation. Verify the serial number or application, then call (562) 693-7748.
