Frequently Asked Questions
Q: What Yale models does the load wheel kit fit?
A: This load wheel kit is engineered specifically for Yale MPB040AC electric pallet trucks. Always verify your equipment nameplate reads MPB040AC before ordering to ensure proper fitment and compatibility.
Q: What are the wheel specifications?
A: This kit includes dual 4.50 inch diameter polyurethane wheels rated at 95A durometer (butterscotch color). Wheels feature 6203z sealed ball bearings providing double-shielded protection against dirt and moisture. Assembly includes hardened steel axles and all necessary fasteners.
Q: What cross-reference part numbers are available?
A: This load wheel kit cross-references as: YL 065269600, YL 065269600-A, YL 643182400-A, YL 643182400, YL 640374100, and YL 501776904. For the harder 97A durometer variant, cross-reference is YL 065269600-XL-A.
Q: What is the difference between standard and XL variants?
A: The standard uses 95A durometer wheels, while the XL variant uses harder 97A durometer wheels. XL is recommended for high-intensity operations, outdoor use, or rough floor surfaces. Both mount identically and are fully compatible with MPB040AC equipment.
Q: Are the 6203z bearings sealed?
A: Yes. The 6203z designation indicates sealed ball bearings with contact seals on both sides, double-shielded against dirt, moisture, and debris. This design significantly extends bearing life in warehouse and outdoor environments. Do not use high-pressure spray washers as this can force water past the seals.
Q: Can I upgrade from standard to XL wheels?
A: Yes. The XL variant is a direct bolt-on replacement with no modifications needed. However, harder 97A wheels may provide a slightly rougher ride on smooth floors and increase steering effort, so test the upgrade before converting multiple units.
