Frequently Asked Questions
Q: What does the -A designation mean on the SU S322-A?
A: The -A suffix indicates this is a complete load wheel assembly, not just the wheel. It includes the poly wheel, bearing, spindle, and axle nut pre-assembled. The SU S322-A is plug-and-play, while SU S322 is the wheel only and requires manual installation on an existing spindle.
Q: Is the SU S322-A compatible with older lift trucks from 2005 and earlier?
A: Likely yes, but verify spindle diameter. The SU S322-A assembly uses a standard 5/8 inch or 3/4 inch bore depending on truck model. Check your truck manual or compare bore size to your existing assembly. If bores differ, the assembly will not fit without spindle replacement.
Q: Can I use just the wheel from SU S322-A if I only need wheel replacement?
A: Not recommended. The SU S322-A is sold as a complete assembly for warranty purposes. If you need only the wheel, order the SU S322 instead, which is more cost-effective. Disassembling the -A unit may damage the bearing or spindle and voids warranty.
Q: What is the installation time for the SU S322-A assembly?
A: Installation takes 5 to 10 minutes per assembly on most lift trucks. Remove the old assembly by unbolting the axle nut, slide off the mounting bracket, and replace with the new SU S322-A. Secure with the existing bolt or provided hardware. No tools other than a wrench are needed.
Q: Does the SU S322-A come pre-greased?
A: Yes. The SU S322-A bearing is factory-greased and sealed. Do not add additional grease, which can cause bearing failure. After 6 months of operation, inspect the bearing for excessive play or noise. If the bearing becomes noisy, replace the entire assembly rather than attempting to regrease.
Q: What warranty does the SU S322-A include?
A: Most SU S322-A assemblies carry a 12-month parts warranty against manufacturing defects. Wear and tear from normal use is not covered. Warranty is voided if the assembly is disassembled or if it fails due to overloading or impact damage. Request a warranty certificate at purchase.
