Frequently Asked Questions
Q: What is the SU 554-XL-A load wheel assembly?
A: The SU 554-XL-A is a complete load wheel assembly including the SU 554-XL wheel, hub, bearings, and mounting hardware pre-assembled and ready for installation. The XL designation indicates heavy-duty formulation for extended wear and maximum load capacity. It is a direct replacement for trucks originally equipped with SU 554-XL-A assemblies.
Q: How does the SU 554-XL-A differ from the SU 554-XL wheel alone?
A: The SU 554-XL is a bare wheel requiring hub and bearing transfer from your old assembly. The SU 554-XL-A comes fully assembled with wheel, hub, and sealed bearings, ready to install directly onto your truck axle in minutes. Choose SU 554-XL-A if you want zero downtime installation or if your existing hub is damaged and needs replacement.
Q: Is the SU 554-XL-A a drop-in replacement for my lift truck?
A: The SU 554-XL-A is a drop-in replacement if your truck originally used a SU 554-XL-A assembly or an equivalent wheel size. Verify your truck manual or existing assembly part number before ordering. Bore size, axle diameter, and wheel dimensions must match your equipment specifications. When in doubt, contact your equipment manufacturer.
Q: What tools do I need to install the SU 554-XL-A assembly?
A: Installation typically requires a socket wrench or hex key to remove the old retaining clip or fastener. Slide the SU 554-XL-A onto the axle and resecure with your existing hardware. No specialized tools, bearing presses, or seals are required. The assembly arrives with bearings sealed and pre-lubricated for immediate service.
Q: How long will the SU 554-XL-A assembly last?
A: The SU 554-XL-A typically delivers 3-5 years of service in standard warehouse conditions. Heavy duty use, rough floors, or extreme loads may reduce lifespan to 18-36 months. Regular inspection every 3 months will help identify wear early. Sealed bearings require no maintenance but cannot be serviced; replace the entire assembly if bearing noise develops.
Q: What warranty or support is available for the SU 554-XL-A?
A: Warranty terms depend on your supplier and product documentation. Standard assemblies typically carry 30-90 day defect coverage from date of purchase. Wear and tear is not covered. Keep your original receipt and part number for warranty claims. Contact your supplier if the assembly fails prematurely or does not perform as specified.
