Frequently Asked Questions
Q: What is the difference between SU 529-XL-A and SU 528-XL-A?
A: Both use Cushothane XL compound, but differ in width. SU 529-XL-A is 6 inches wide; SU 528-XL-A is 6.375 inches wide. Check your truck hub width before ordering. Installing the wrong width will cause the wheel to overhang or bind on the frame.
Q: Is SU 529-XL-A a direct replacement for all Yale electric pallet trucks?
A: No. Yale uses multiple wheel sizes and bore diameters across models and serial ranges. SU 529-XL-A fits trucks with a 3.25 inch wheel diameter, 6 inch width, and 2.0467 inch bore OD. Always verify your truck parts number before ordering. Mismatched wheels void equipment warranty.
Q: Can I order SU 529-XL-A with bearings and seals pre-installed?
A: Typically no. SU 529-XL-A ships as wheel and hub only. Most distributors require you to specify bearing type and source a seal kit separately, as bearing selection varies by truck OEM. Contact your supplier about pre-assembly options if available.
Q: How do I prevent SU 529-XL-A from hardening prematurely in outdoor storage?
A: Store indoors in a cool location (50 to 75 degrees Fahrenheit recommended). Avoid prolonged sun exposure, heat, and ozone from arc welders or electric motors. Do not store near solvents or reactive chemicals. Proper storage extends shelf life from 12 months to 24 months or longer.
Q: What diagnostic signs indicate SU 529-XL-A wheels need replacement?
A: Replace when tread develops flat spots, cracks, or visible hardening (does not bounce when tapped). Steering becomes stiff or pulls to one side if wheels wear unevenly. Loss of quiet operation or increased vibration also indicates wear. Do not wait for complete tread loss; replacement becomes dangerous and damages the truck frame.
