Frequently Asked Questions
Q: What is the SU 423-A Load Wheel Assembly used for?
A: The SU 423-A is a complete load wheel assembly for electric lift trucks and pallet jacks. It includes the wheel, hub, and mounting hardware as a single unit. Use this when you need a plug-and-play replacement without sourcing individual components separately.
Q: How do I know if the SU 423-A needs replacement?
A: Replace the SU 423-A when you notice flat spots on the wheel, cracking or chunking in the wheel material, difficulty steering, or the wheel no longer rolls freely under load. If the truck pulls to one side after alignment, the wheel assembly may be damaged and needs replacement.
Q: What lift truck models are compatible with the SU 423-A?
A: Compatibility depends on your specific truck model and serial range. Always verify your current wheel diameter, width, bore size, and mounting style before ordering. Contact the manufacturer with your truck model number to confirm SU 423-A fitment.
Q: Is the SU 423-A assembly or wheel-only?
A: The SU 423-A includes the complete assembly with hub and mounting components ready to install. You do not need to remove the wheel from a hub or swap components. It is a direct bolt-on replacement.
Q: What tools are required to install the SU 423-A?
A: Installation typically requires basic hand tools: wrenches or sockets to match your trucks bolt size, a lift or jack to raise the truck safely, and possibly a rubber mallet to seat the wheel. Follow your truck manual for torque specifications and always use safety blocks.
Q: How long does the SU 423-A typically last?
A: Lifespan depends on load, surface conditions, and maintenance. Heavy use on rough floors may require replacement every 12-24 months. Light indoor use can extend life to 3-5 years. Inspect the wheel quarterly for wear.
