Frequently Asked Questions
Q: What is included in the SU 556-XL-A load wheel assembly?
A: The SU 556-XL-A includes the load wheel, hub, bearings, and fasteners pre-assembled. It is ready to bolt directly onto your electric lift truck without additional bearing installation or machining.
Q: How does the SU 556-XL-A differ from the SU 556-XL wheel alone?
A: The SU 556-XL is the wheel component only. The SU 556-XL-A is a complete assembly with the wheel, hub, bearings, and all hardware ready to install. Choose the assembly if you do not have a core hub or do not want to reuse your existing hub.
Q: What tools do I need to install the SU 556-XL-A?
A: You need a socket set or wrench to match your truck bolt pattern, a jack to lift the truck, and basic safety blocks. Do not work under a truck supported only by a jack; use safety stands. Installation typically takes 30-60 minutes per wheel.
Q: Is the SU 556-XL-A compatible with my truck model?
A: Compatibility depends on your electric lift truck model and serial number. Verify the bolt pattern, wheel bore diameter, and mounting style against your truck documentation or contact support with your truck model to confirm fitment before ordering.
Q: Can I reuse my old hub with the SU 556-XL wheel if I only need the wheel?
A: Yes, if your existing hub is in good condition and the bore diameter matches the SU 556-XL specifications. Check that the hub is not cracked, bent, or worn. If the old hub shows signs of damage, order the SU 556-XL-A assembly to avoid wheel failure.
