Frequently Asked Questions
Q: What Yale models does GWK-MPB040AC-LW fit?
A: GWK-MPB040AC-LW is engineered for Yale MPB040AC electric pallet trucks. It is not compatible with MPB040AB models (different specifications). Verify your equipment nameplate reads MPB040AC before ordering. Mixing incompatible wheel kits will result in poor fitment or equipment damage.
Q: What are the cross-reference part numbers for GWK-MPB040AC-LW?
A: GWK-MPB040AC-LW cross-references as follows: YL 065269600, YL 065269600-A, YL 643182400-A, YL 643182400, YL 640374100, and YL 501776904. All these part numbers supply the same wheel assembly. For XL variant with 97A durometer wheels, cross-reference is YL 065269600-XL-A (equivalent to GWK-MPB040AC-LW-XL).
Q: What are the wheel specifications for this standard load wheel kit?
A: GWK-MPB040AC-LW includes dual 4.50 inch diameter polyurethane wheels rated at 95A durometer (butterscotch color). Wheels feature 6203z sealed ball bearings for corrosion protection and extended service life. The assembly includes hardened steel axles and all necessary fasteners for installation. The hub surface is machined with a polyurethane tread mold.
Q: What is the difference between standard GWK-MPB040AC-LW and the XL variant GWK-MPB040AC-LW-XL?
A: The standard GWK-MPB040AC-LW uses 95A durometer wheels, while GWK-MPB040AC-LW-XL (equivalent to YL 065269600-XL-A) uses harder 97A durometer wheels. The XL variant is recommended for high-intensity operations, outdoor use, or rough floor surfaces. Both kits mount identically and are fully compatible with MPB040AC equipment.
Q: Are 6203z bearings sealed against dirt and moisture?
A: Yes. 6203z designation indicates sealed ball bearings with contact seals on both sides. The z suffix means the bearings are double-shielded against dirt, moisture, and debris ingress. This design significantly extends bearing life in warehouse and outdoor environments. Do not wash wheels in high-pressure spray as this can force water past the seals.
Q: Can I upgrade from standard GWK-MPB040AC-LW to XL wheels without other modifications?
A: Yes. GWK-MPB040AC-LW-XL is a direct bolt-on replacement for the standard GWK-MPB040AC-LW. No axle, bearing, or fastener modifications are required. The XL wheels are a straightforward durometer upgrade. However, the harder 97A wheels may provide a slightly rougher ride on smooth floors and increase steering effort, so test the upgrade before converting all units.
