LOCKWASHER (Hyster HY1557011)

A damaged lockwasher can allow fastener loosening under vibration, leading to component separation. The lockwasher type provides spring tension to resist rotational loosening of threaded fasteners. Hyster lists this part under catalog number HY1557011 as an aftermarket replacement reference. A worn lockwasher may fail to maintain clamping force, resulting in joint slack and potential mechanical noise. During assembly, a lockwasher's split or toothed design bites into mating surfaces to prevent backing out. This item ships at approximately 0.002 POUNDS. Verify the serial number or application, then call (562) 693-7748.
