Lock Washer for Yale Electric Lift Truck

Frequently Asked Questions

Q: What is the YL 220170714 lock washer?
A: The YL 220170714 is a lock washer designed to prevent fasteners from loosening due to vibration and movement. It is used in Yale electric lift trucks and pallet jacks where fastener retention is critical for safety and reliability.

Q: What is the material and design type of this lock washer?
A: This Yale lock washer is manufactured from steel and designed to resist vibration-induced fastener loosening. The exact design type (split ring, toothed, or helical) is specified by the Yale part standard. It provides consistent friction and retention across material handling equipment.

Q: Where is the YL 220170714 used on Yale equipment?
A: Lock washers of this type are used on critical fasteners throughout the lift truck or pallet jack frame, drive assembly, and wheel mounting points. The specific mounting location depends on your equipment model and assembly configuration.

Q: Why is it important to use the correct lock washer?
A: Using the correct OEM lock washer ensures proper fastener retention under operating vibration. Substituting with generic washers or omitting washers altogether allows fasteners to loosen, leading to frame damage, misalignment, and potential equipment failure or safety hazards.

Q: Do lock washers wear out and require replacement?
A: Lock washers degrade over time through vibration cycles and can lose effectiveness after extended use. If fasteners repeatedly loosen during routine maintenance, replace the lock washers along with the fastener. This is especially important in high-vibration applications.
