Frequently Asked Questions
Q: What is the difference between YL 504574280 and YL 504574280-A?
A: Both part numbers refer to the same Yale load wheel assembly with identical specifications: 3.25 inch diameter by 4.50 inch width, Durarun 95A polyurethane tread, and cast iron core. The -A suffix indicates a complete assembly configuration that includes sealed bearings and hardware ready for mounting.
Q: Is the YL 504574280-A compatible with Yale MPB 040 and MPO40AC equipment?
A: The YL 504574280-A is confirmed compatible with Yale MPO40AC series electric lift trucks. Verify fitment with Yale MPB 040 series by confirming your specific equipment serial range against the original parts documentation, as model designations and revision levels affect compatibility.
Q: What cross-reference part numbers apply to YL 504574280-A?
A: The YL 504574280-A cross-references with YL504574280, YT504574280, and 504574280. These variations represent the same wheel assembly under different Yale part numbering conventions. Always verify against your equipment documentation that the diameter and width specifications match.
Q: Does this wheel assembly come pre-assembled with bearings and axle hardware?
A: Yes, the YL 504574280-A is a complete direct OEM replacement assembly. It arrives with sealed bearings, axle, and installation hardware ready for mounting. This eliminates the need to source and assemble multiple components separately.
Q: How does polyurethane compound protect warehouse floors?
A: The Durarun 95A polyurethane tread provides a slightly softer contact surface compared to hard plastic or rubber alternatives, reducing impact noise and minimizing floor scuffing. The polyurethane compound is less likely to leave dark marks or damage sealed concrete, epoxy, or polished floors common in food and pharmaceutical facilities.
