Frequently Asked Questions
Q: What are the dimensions and specifications of the 524250486-XL load wheel?
A: This Yale load wheel assembly has a 3.25-inch (83 mm) diameter and 4.5-inch (114 mm) width. The tread is constructed from 97 Shore A durometer polyurethane for durability and grip in warehouse conditions. The wheel core is machined steel with shielded ball bearings (BS 6205-ZZ specification) and integrated string guards to protect against debris contamination.
Q: Which Yale pallet jack models are compatible with the 524250486-XL?
A: This wheel assembly is a direct replacement for Yale electric pallet truck models MPB040E, MPW045E, and MPW050E. These are mid-range electric walkie pallet jacks commonly used in distribution and warehouse environments for load handling and transport.
Q: What does the 97 Shore A durometer rating mean?
A: Shore A durometer measures polyurethane hardness on a scale of 0-100. A 97A rating indicates a hard, durable tread that resists wear and maintains shape under heavy loads. This hardness level is standard for load wheels in warehouse environments and provides good performance on clean, dry concrete floors.
Q: What part numbers relate to the 524250486-XL?
A: The 524250486-XL replaces the earlier 524250486 part number and supersedes the 524250482-XL. When ordering as a complete kit with axles and fasteners, request part number 524250486-XL-KIT.
Q: What is the typical service life of this load wheel?
A: Service life depends on operating conditions, load weight, and floor surface. In typical warehouse use with standard loads on clean floors, expect 18 to 36 months of service. Heavy daily use, hard flooring, or exposure to moisture and debris will reduce lifespan and accelerate bearing wear.
Q: Why are string guards included on this wheel?
A: String guards prevent plastic film, stretch wrap, and string debris from wrapping around the wheel axle, which can jam the bearings and immobilize the truck. They extend wheel and bearing life by keeping contaminants away from bearing seals and rotating surfaces.
Q: Should this wheel be stored in any particular way when not in use?
A: Store the wheel indoors in a dry location away from direct sunlight and moisture. Keep it on a clean surface where debris cannot accumulate on the bearing seals. Avoid stacking heavy items on top of the wheel, as this can damage the shielded bearing seals.
