Frequently Asked Questions
Q: What is the load capacity of the SU S449-XL-A poly load wheel assembly?
A: The SU S449-XL-A is rated for electric lift truck applications with a 97A durometer polyurethane wheel. Always verify the load rating against your truck model documentation, as capacity depends on wheel mounting position and truck configuration. Exceeding rated load will cause premature wear and tread failure.
Q: Is the SU S449-XL-A compatible with non-branded lift truck wheels?
A: SU S449-XL-A is a poly load wheel assembly for electric lift trucks. Cross-check your truck model serial range and wheel bore diameter before installation. If your truck uses a different bore size or bolt pattern, you will need to verify compatibility or consider an adapter. Do not force incompatible wheels onto the axle.
Q: How do I install the SU S449-XL-A assembly on my electric lift truck?
A: Remove the old wheel assembly from the axle. Slide the SU S449-XL-A onto the axle shaft, ensuring the bore seats fully and evenly. Reinstall any retaining clips, washers, or fasteners in their original order. Spin the wheel by hand to confirm free rotation with no binding. If the wheel does not spin freely, check for misalignment or debris.
Q: What is the maintenance schedule for the SU S449-XL-A load wheel?
A: Inspect wheels weekly for cracks, flat spots, or uneven wear. Clean polyurethane wheels with mild soap and water to remove debris that can embed and cause tracking issues. If a wheel develops a bulge, flat spot, or chunk missing from the tread, remove it immediately as it will damage the axle bearing and cause unsafe handling.
Q: What causes rapid wear on the SU S449-XL-A assembly and how do I diagnose it?
A: Rapid wear typically results from overload, dry bearing conditions, or misalignment. Check for play in the axle shaft by rocking the wheel side to side. If movement exists, the bearing or shaft is failing. Uneven wear on one edge indicates axle misalignment or a bent truck frame. Replace the wheel and inspect the axle bearing condition.
