LOCKWASHER
Frequently Asked Questions
Q: What is the 3702491 lockwasher and what does it do?
A: The 3702491 is a split or toothed lockwasher used on manual pallet jacks and material handling equipment to prevent fasteners from loosening due to vibration. It sits under bolt heads and nuts to maintain tension on critical components like pump assemblies, wheel mounts, and hydraulic connections.
Q: What are the dimensions and material of the 3702491 lockwasher?
A: The 3702491 lockwasher is manufactured from hardened steel or stainless steel depending on application requirements. Verify the exact bore diameter, outer diameter, and thickness by consulting your equipment parts diagram before ordering to ensure proper fit with your fastener.
Q: Which manual pallet jack models use the 3702491 lockwasher?
A: The 3702491 fits standard manual pallet jacks from Crown, Toyota, Raymond, Yale, and other OEM manufacturers. Verify your specific models pump assembly, fork yoke, or actuator bolt specifications against the 3702491 dimensions before ordering.
Q: What is the load rating of the 3702491 lockwasher?
A: The load rating depends on the bolt diameter and material grade. Typical split lockwashers in manual pallet jack applications support fasteners rated for 1000 to 5000 pounds of tensile load. Always pair this washer with bolts and nuts of matching or greater grade rating.
Q: Can the 3702491 lockwasher be reused after removal?
A: No. Split and toothed lockwashers lose their spring tension after one installation cycle and cannot reliably prevent fastener loosening on reuse. Always replace the lockwasher when removing and reinstalling fasteners on pallet jacks.
Q: Is the 3702491 available in stainless steel or only hardened steel?
A: The 3702491 is manufactured in hardened steel for standard applications. If you require stainless steel for corrosion resistance in wet storage or outdoor use, verify availability and lead time by contacting us with your specific requirement.
