Frequently Asked Questions
Q: Is GWK-PUAA-LW compatible with all Wesley Pallet Mule models?
A: No. GWK-PUAA-LW is designed specifically for the Pallet Mule AA5500 model only. Other Pallet Mule models use different wheel sizes and bearing configurations. Verify your model number on the jack nameplate before ordering. Installing this kit on the wrong model will result in fit issues and unsafe operation.
Q: What wheel material is used and what are the wear characteristics?
A: GWK-PUAA-LW uses ultra-polyurethane 70D Shore wheels. This material offers a good balance of grip and wear resistance for both smooth and slightly textured floors. On heavily abrasive surfaces like concrete with debris, expect wear life of 18 to 24 months. On clean epoxy floors, life extends to 3 years or more. Slower operational speeds reduce heat and extend wheel life.
Q: What symptoms indicate the AA5500 load wheels need replacement?
A: Replace wheels when you observe tread wear down to the base layer, visible cracks or chunks missing, flat spots from skidding, or reduced maneuverability. A soft or spongy feel in the grip also indicates internal deterioration. Noise during push-pull operation or resistance during idle spin are bearing failure indicators. Do not delay; worn wheels reduce load stability and increase slip hazards.
Q: Can GWK-PUAA-LW wheels be repaired or only replaced?
A: Wheels cannot be economically repaired. Polyurethane wheels are sealed units with integral bearings. If a wheel is damaged, the entire wheel assembly must be replaced. Attempting to shave or resurface a worn wheel will not restore load capacity or safety. Always replace the complete wheel assembly as supplied in the kit.
Q: What maintenance steps extend the life of GWK-PUAA-LW wheels?
A: Inspect wheels weekly for cracks and embedded debris. Keep floors clean of metal shavings, oils, and standing water. Store the jack indoors when not in use to prevent UV and temperature damage. Rotate load paths to avoid repetitive wear in the same spot. Check that axles spin freely monthly; any binding indicates bearing trouble. Average replacement interval under normal warehouse use is 2 to 3 years.
Q: Are there any equivalent part numbers or cross-references for AA5500 wheels?
A: GWK-PUAA-LW is the standard replacement part for Wesley Pallet Mule AA5500 jacks. Consult the Pallet Mule parts catalog or contact the manufacturer for any OEM equivalent numbers. Do not source wheels from generic suppliers without confirming exact bore size, wheel diameter, and load rating specifications match the AA5500 frame design.
