Frequently Asked Questions
Q: What is the YL 522520001 fork pin kit used for?
A: The YL 522520001 fork pin kit consists of hardened steel pins and mechanical retainers designed for Class II Yale electric lift trucks. These pins secure fork assemblies to the load carriage, allowing safe material handling and load positioning.
Q: What are the exact specifications of the YL 522520001 fork pins?
A: The YL 522520001 consists of 1/2 inch diameter pins with 2-3/64 inch length, manufactured from SAE 1045 through-hardened carbon steel. Each pin includes a mechanical retainer to prevent accidental removal during operation. These dimensions ensure proper fit in Yale Class II lift truck carriage slots and consistent load control.
Q: How do I verify the YL 522520001 is compatible with my truck?
A: The YL 522520001 is engineered for Yale Class II electric lift trucks. Verify your truck is Class II capacity. Check your truck manual or serial plate for the OEM part number YL 522520001 or alternate numbers YT522520001. If your truck references different part numbers, contact us with your model and serial number.
Q: Why is SAE 1045 carbon steel used for the YL 522520001 pins?
A: SAE 1045 through-hardened carbon steel provides high tensile strength and wear resistance necessary to withstand repeated insertion, removal, and heavy fork loads without shearing or bending. This material specification ensures the pins maintain dimensional stability and secure the forks reliably throughout their service life.
Q: What is the mechanical retainer on the YL 522520001 and how does it work?
A: The mechanical retainer is a spring clip or lock washer that holds each pin in place and prevents accidental withdrawal. The retainer must remain engaged during truck operation. If the retainer is missing, damaged, or loose, the fork pins can fall out, creating a safety hazard. Replace both pin and retainer if either is damaged.
