Frequently Asked Questions
Q: What is the YL 520318811 bolt specification?
A: The YL 520318811 is a bolt with integral lock nut assembly for Yale electric lift truck applications. It is supplied as a complete fastener package and does not require separate lock washer sourcing. Verify the bolt diameter and length requirements for your specific mounting location before ordering.
Q: What Yale models use the YL 520318811 bolt with lock nut?
A: The YL 520318811 is an OEM fastener for Yale electric pallet jacks and lift trucks. Common mounting locations include caster wheel assemblies, frame brackets, and drive motor mounts. Confirm your equipment model and serial range to verify this part is the correct replacement.
Q: Is the YL 520318811 lock nut reusable?
A: Lock nuts are designed for repeated assembly and disassembly cycles. However, after multiple installation and removal cycles, the nylon lock element loses its grip strength. If a bolt with lock nut repeatedly loosens during operation, replace the YL 520318811 assembly rather than attempting to reuse a worn lock nut.
Q: What is the material composition of the YL 520318811?
A: The YL 520318811 bolt and lock nut assembly is manufactured from hardened steel. The lock nut contains a nylon insert that creates friction to prevent vibration-induced loosening. This is a precision-machined assembly engineered to OEM specifications.
Q: How many YL 520318811 bolts do I need for a caster wheel replacement?
A: The number of fasteners required depends on your specific caster wheel assembly design and mounting configuration. Refer to your equipment documentation or contact us with your model number and serial range to determine the exact quantity and fastener count needed for your repair.
