Frequently Asked Questions
Q: What electric lift truck models does the SU 258-XL-A assembly fit?
A: The SU 258-XL-A load wheel assembly is designed for Yale, Hyster, and Nissan electric pallet jacks with serial range 2015 and later. XL designation indicates oversized 8-inch diameter wheel. Always verify your vehicle VIN against the compatibility matrix before ordering.
Q: Can I replace just the wheel on the SU 258-XL-A assembly or do I need the full assembly?
A: The SU 258-XL-A ships as a complete assembly including wheel, bearing, spacer, and axle bolt. Individual wheel replacement is not recommended unless bearing inspection confirms reusability. If only the wheel tread is worn, you must replace the entire assembly to ensure proper load distribution and safety.
Q: How do I diagnose a bad SU 258-XL-A load wheel assembly?
A: Signs of failure include squeaking or grinding noise during operation, visible flat spots or uneven wear on the wheel, truck pulling to one side, or resistance when manually spinning the wheel by hand. Inspect for cracks in the wheel rim or bearing play by grasping the wheel and pushing side-to-side. Replace the assembly if any play is detected.
Q: What is the maximum load rating and wheel diameter of the SU 258-XL-A?
A: The SU 258-XL-A assembly supports up to 6000 pounds per wheel with an 8-inch diameter wheel and 2-inch width. Exceeding this load rating will result in accelerated bearing wear and wheel failure. Do not use on rough or uneven concrete surfaces as this significantly reduces service life.
Q: Is the SU 258-XL-A equivalent to any other brand assemblies?
A: Yes, the SU 258-XL-A is equivalent to Yale YL-588439201 and Hyster HY 1438971. All three provide identical 8-inch oversized wheel performance and bearing specifications. Cross-reference your vehicle documentation to confirm correct part selection before installation.
Q: What maintenance is required for the SU 258-XL-A assembly?
A: Inspect bearings quarterly and lubricate with general-purpose bearing grease per manufacturer specs. Clean wheel surface monthly to remove debris and inspect for cracks. Replace the assembly immediately if bearing seals are damaged or if grease appears contaminated with water. Expected service life is 18-24 months under normal warehouse conditions.
