Frequently Asked Questions
Q: What is SKU 92515413 and where is it used?
A: SKU 92515413 is a lock washer for manual pallet jacks. It prevents fasteners from loosening due to vibration and repetitive loading on the pump assembly, hydraulic connections, and load-bearing pivot points.
Q: What size and material is this lock washer?
A: For exact specifications including inside diameter, outside diameter, thickness, and material grade, contact us with your manual pallet jack model or provide the bolt size where this washer will be used.
Q: Which manual pallet jack brands use part number 92515413?
A: This lock washer is compatible with manual pallet jacks from Crown, Toyota, Raymond, Yale, and other standard platform truck manufacturers. Verify compatibility with your specific pallet jack serial number.
Q: How long do lock washers last, and when should they be replaced?
A: Lock washers lose effectiveness after repeated use and vibration exposure. Replace them whenever fasteners are disassembled or when you notice loose connections despite proper torque. Do not reuse lock washers once removed.
Q: Can I use a standard flat washer instead of a lock washer?
A: No. Lock washers are designed to prevent fastener rotation and loosening. Standard flat washers provide no anti-rotation function. Using the correct lock washer ensures equipment safety and prevents hydraulic leaks on pump connections.
