LOCKWASHER
Frequently Asked Questions
Q: What is a lockwasher and why is it used on manual pallet jacks?
A: The 1384992 lockwasher prevents fasteners from loosening due to vibration and repeated handling cycles on manual pallet jacks. Lock washers deform slightly under compression to create a mechanical lock that maintains fastener tension even with constant movement and load shifts common in warehouse use.
Q: What manual pallet jack models require the 1384992 lockwasher?
A: The 1384992 fits standard manual pallet jacks from Crown, Toyota, Raymond, Yale, and generic aftermarket hydraulic pallet jacks. It is used in pump assemblies, wheel brackets, and handle mounting points. Confirm fastener diameter and thread pitch before ordering.
Q: What type of lockwasher is the 1384992?
A: The 1384992 is a split ring or toothed lockwasher manufactured from hardened steel. The teeth or split design engage into the fastener head and nut, creating mechanical resistance to rotation. Do not mix different lockwasher types on the same assembly.
Q: How long does a lockwasher remain effective?
A: A properly installed lockwasher typically maintains grip for 2 to 5 years under normal pallet jack use. Corrosion, repeated assembly and disassembly, or overtightening degrades lockwasher performance. Replace lockwashers during pump overhauls or when fasteners require removal.
Q: Can the 1384992 lockwasher be reused after removal?
A: Lockwashers lose mechanical grip after removal and should be replaced rather than reused. Reinstalling a used lockwasher will not provide the same vibration resistance. The cost of new washers makes replacement the best practice for equipment reliability.
