Frequently Asked Questions
Q: Is GWK-WESCO-CK a direct replacement for GWK-CPI-CK?
A: Yes, GWK-WESCO-CK is equivalent to GWK-CPI-CK and is compatible with all Wesco CPI series manual pallet jacks. Both SKUs refer to the same complete wheel kit. If you have an older jack with part reference GWK-CPI-CK, you can order GWK-WESCO-CK as a replacement. Verify your jack model reads CPI or Wesco CPI before ordering.
Q: Does this kit include both load and steer wheels?
A: Yes, GWK-WESCO-CK is a complete wheel kit containing load wheels (3 x 3.375 inch) and steer wheels (8 x 2 inch), all with sealed ball bearings. You do not need to purchase wheels separately. The kit includes everything required for a full replacement except lubricant for the steering pivot (if needed).
Q: What does polymer composite core mean for the load wheels?
A: Polymer composite core uses a plastic or resin-based center instead of metal, reducing weight and improving corrosion resistance. This design is ideal for wet or outdoor environments where metal cores might rust. The composite core does not affect load capacity and is standard for Wesco CPI jacks.
Q: Why are Grade 8 fasteners specified instead of standard bolts?
A: Grade 8 fasteners have higher tensile strength and are designed to withstand repeated vibration and stress cycles without loosening. Manual pallet jacks experience significant shock loads when loaded and moved. Grade 8 fasteners resist loosening and prevent wheel wobble. Do not substitute with lower-grade fasteners.
Q: Can I use these wheels as a retrofit upgrade on an older non-Wesco pallet jack?
A: GWK-WESCO-CK is designed specifically for Wesco CPI pallet jacks and may not fit other brands due to different axle diameters and wheel pocket dimensions. Cross-fitment is not guaranteed. Only use this kit on Wesco-branded or OEM-equivalent CPI jacks. Verify axle diameter and wheel pocket width match before attempting installation on non-Wesco jacks.
Q: What is the typical service life for the ultra-polyurethane wheels in this kit?
A: Under normal warehouse use (8 to 10 hours daily), expect 24 to 36 months of service. Outdoor use or high-friction surfaces (rough concrete, asphalt) will reduce life to 12 to 18 months. Replace the kit if any wheel shows flat spots, cracking, or glazing. Inspect wheels every 3 months during the second year of service.
