Frequently Asked Questions
Q: What is included in the SU 654-EZ-A load wheel assembly?
A: The SU 654-EZ-A is a complete preassembled unit with the 5.000 inch by 3.625 inch Cushothane XL wheel and bearings already installed. The assembly is ready to mount onto your axle. Do not disassemble unless bearing replacement is required. Verify bore size is 2.188 inches before ordering to ensure axle compatibility.
Q: Can I replace just the wheel on the SU 654-EZ-A assembly or do I need to replace the entire unit?
A: If only the tread is worn and bearings are still smooth and quiet, you can sometimes replace just the wheel by pressing off the old wheel and pressing on a new one. This requires a bearing press and proper tooling. If bearings are noisy, grinding, or worn, replace the entire assembly. Most field technicians recommend replacing the complete assembly for warranty and consistency.
Q: How do I diagnose a bearing failure on the SU 654-EZ-A?
A: Listen for grinding, squeaking, or rumbling noise during wheel rotation under load. Feel the wheel hub for unusual heat after operation, it should be warm but not hot enough to cause discomfort. Check for lateral play by grasping the wheel rim and trying to rock it side-to-side. Any movement means bearings are worn. A failed bearing reduces wheel control and creates safety risk, replace the assembly immediately.
Q: What maintenance does the SU 654-EZ-A assembly require?
A: The SU 654-EZ-A uses sealed bearings that do not require lubrication. Inspect the tread for wear and damage monthly. Keep the wheel clean and dry. Do not pressure wash directly at the bearing seals. Rotate or replace wheels every 500 to 800 operating hours depending on usage intensity. Store indoors away from UV light when not in use.
Q: Is the SU 654-EZ-A equivalent to other part numbers?
A: The SU 654-EZ-A is specific to its manufacturer. Always verify the exact part number on your lift truck documentation before ordering. Some manufacturers use different numbering for identical wheel and bearing assemblies. If you are uncertain, provide your lift truck model and current wheel part number to confirm compatibility. Mixing mismatched wheel assemblies can cause operational issues.
