Frequently Asked Questions
Q: Is GWK-MPB040AC-XL-LW compatible with Yale MPB 040 AC electric pallet jacks?
A: Yes. This load wheel kit is engineered specifically for Yale MP/MPB 040 AC electric pallet jack series. The XL-polyurethane wheels with 4.500-inch diameter and 6203Z shielded bearings mount directly using OEM-grade hardware. Verify your jack model nameplate reads MPB040 AC or MP040 AC before ordering.
Q: What is the difference between GWK-MPB040AC-XL-LW and other 040 series wheel kits?
A: GWK-MPB040AC-XL-LW is rated 97A Shore hardness with XL-polyurethane formulation and is designed for AC electric models only. The 040 E series uses different wheel sizing and bearing configurations. Do not cross-fit this kit to 040 E or 040 AB models as axle bore diameters and fastener patterns differ.
Q: How do I install GWK-MPB040AC-XL-LW wheels on my Yale electric pallet jack?
A: Lift the jack fully on blocks and secure it. Remove the cotter pins and nuts holding the old wheels. Slide the wheel assemblies off the axles. Install the new 6203Z bearings on precision axles if not pre-assembled, then slide wheels onto axles, thread nuts hand-tight, insert cotter pins, and verify wheels spin freely. Do not overtighten.
Q: What load capacity does the GWK-MPB040AC-XL-LW support?
A: This wheel kit maintains the original 4000-pound load capacity rating of the Yale MPB 040 AC jack. Wheel failure typically occurs from worn bearings or impact damage, not from load. If wheels lock or drag under normal load, inspect bearings for rust or debris before assuming overload.
Q: How long should GWK-MPB040AC-XL-LW wheels last in typical warehouse use?
A: 97A durometer XL-polyurethane wheels typically provide 12 to 18 months of service in continuous material handling operations, depending on floor conditions and load cycles. Rough concrete and outdoor use accelerates tread wear. Sealed 6203Z bearings require no greasing. Replace wheels when tread depth falls below one-quarter inch or if tread separation occurs.
