LOCKWASHER (JLG JL91144182)

A worn lockwasher can lead to fastener loosening under vibration. This aftermarket replacement part references the JLG catalog number JL91144182. A lockwasher is a type of hardware washer that creates tension between a fastener and its mating surface. Its plain mechanical function is to resist rotational loosening by biting into the surfaces it contacts. A common generic failure consequence is that a missing or collapsed lockwasher allows the nut or bolt to back off, causing joint separation. During assembly, the lockwasher should be compressed flat to ensure proper locking action. Verify the serial number or application, then call (562) 693-7748.
