Frequently Asked Questions
Q: What is the OEM part number for GWK-WPT45-LW?
A: GWK-WPT45-LW is the OEM part number itself for Big Joe WPT45 electric pallet jacks. Cross-reference SKU GWK-WPT-LW is equivalent. Both provide 95A polyurethane wheels with precision assembly and hardware. Verify your truck serial number on the nameplate to confirm correct fit before purchasing.
Q: What is included in the complete assembly?
A: GWK-WPT45-LW is supplied as a complete kit with two polyurethane load wheels, steel axles, sealed bearings, and all required installation fasteners. No additional bolts, washers, or spacers are needed for direct replacement. Remove old wheels, clean the axle mounting surfaces with a dry cloth, and install new wheels using provided fasteners tightened to 22 to 28 foot-pounds.
Q: Is this an OEM replacement or an aftermarket alternative?
A: GWK-WPT45-LW is the original equipment manufacturer (OEM) replacement kit for Big Joe WPT45 trucks. It meets Big Joe engineering specifications and carries the same warranty as original wheels. If you need extended durability or higher load capacity, the aftermarket GWK-WPT-LW-XL (97A durometer) variant offers similar fitment with enhanced performance.
Q: What fastener material is used and should I replace fasteners during installation?
A: All fasteners supplied in GWK-WPT45-LW are Grade 5 steel, hardened to resist vibration loosening. Use only the provided fasteners; do not reuse old fasteners from the worn wheel kit. Grade 5 bolts are stronger than Grade 2 and resist backing out under operating shock loads. Tighten fasteners in a cross pattern (if two per wheel), then perform a final check after the truck has moved 50 pallets.
Q: What is the standard load capacity of a WPT45 truck with this wheel kit?
A: GWK-WPT45-LW supports the Big Joe WPT45 nameplate capacity, typically 4,500 lbs at 24 inch load center for standard pallet depth (40 to 48 inches). Wheels do not limit capacity; the truck mast and steering are the constraint. Never exceed truck capacity. For loads approaching beyond 24 inches, reduce load approximately 10 percent per additional 6 inches of approach.
Q: How often should sealed wheel bearings be inspected or serviced?
A: Sealed bearings in GWK-WPT45-LW are pre-lubricated and not field-serviceable. Perform visual inspection every 3 months: spin each wheel by hand and listen for grinding or roughness. If you hear grinding or feel resistance, the bearing is failing and the entire wheel assembly must be replaced. Do not attempt to disassemble, clean, or repack sealed bearings; this voids warranty and causes immediate failure.
