A: The YL 504820502 is a polyurethane wheel with dimensions of 3 1/4 inches wide by 4 3/4 inches in diameter. This wheel is designed for mid-range load electric lift trucks. Check your axle bore diameter and bearing type against the equipment manual before ordering to ensure compatibility.
Q: What is the difference between the YL 504820502 and the YL 504820504?
A: The YL 504820502 measures 3 1/4 by 4 3/4 inches, while the YL 504820504 measures 3 1/4 by 2 3/4 inches. The 504820504 is narrower and suited for different axle configurations. Measure your existing wheel or consult your equipment serial number range to order the correct width.
Q: Which equipment brands accept the YL 504820502 wheel?
A: The YL 504820502 is compatible with electric lift trucks from Raymond, Toyota, Crown, and similar mid-size load capacity equipment. Compatibility depends on axle diameter and bearing specifications. Confirm your model number against the compatibility chart before purchasing.
Q: How often should the YL 504820502 be replaced?
A: Polyurethane wheels typically require replacement every 2000 to 4000 operating hours depending on load, floor conditions, and usage pattern. Monitor for flat spots, cracking, or visible wear. Replace if the wheel cannot roll freely or if lateral play develops between the wheel and axle.
Q: What maintenance does the YL 504820502 require?
A: Inspect wheels monthly for debris, buildup, or damage. Clean the wheel surface with a damp cloth to maintain traction. Check the axle bolt for tightness quarterly. Do not apply lubricants to the wheel tread as this reduces traction.
Q: Can the YL 504820502 be used in cold storage environments?
A: Standard polyurethane wheels may become brittle in cold storage below minus 10 degrees Fahrenheit. For consistent cold storage use, specify high-traction polyurethane wheels formulated for low-temperature environments. Check your equipment manual for temperature operating limits.
