Frequently Asked Questions
Q: What applications does the 852143 washer support?
A: The 852143 is a heavy-duty washer designed for fork pin assemblies, steering linkage bolts, and high-vibration connection points on electric and manual pallet jacks. It prevents fastener migration and reduces noise from assembly movement.
Q: What is the material composition of the 852143?
A: The 852143 is constructed from steel with a bright zinc finish for corrosion resistance. The material provides superior vibration damping compared to plain steel, extending fastener life in high-cycle material handling operations.
Q: Is the 852143 compatible with lithium-ion pallet jacks?
A: Yes, the 852143 is compatible with lithium-ion electric pallet jacks from Crown, Toyota, and Raymond, as well as traditional lead-acid battery models. Cross-reference your equipment serial number to confirm bolt specifications match.
Q: What is the service life of the 852143 washer?
A: The 852143 typically delivers 2,500 to 4,500 service hours in warehouse environments. Service life depends on load cycles, fastener torque consistency, and whether the jack operates in temperature-controlled or wet storage areas.
Q: How do I know when to replace the 852143?
A: Replace the 852143 if you observe flattening, permanent indentation, visible rust that penetrates the zinc coating, or if fasteners loosen repeatedly at the same connection point after retightening. Check all washers during quarterly maintenance cycles.
