Frequently Asked Questions
Q: What is the difference between GWK-W40Z-LW-XL and the standard GWK-W40Z-LW?
A: GWK-W40Z-LW-XL features 97A Shore hardness polyurethane wheels, which is 2 points harder than the standard 95A. The XL version also includes heat-treated alloy steel axles and Grade 8 mounting fasteners for higher durability in heavy-duty operations. Both fit W40Z and W45Z (B218 and C215 chassis), but the XL is engineered for extended wear life.
Q: Is GWK-W40Z-LW-XL compatible with Hyster W40Z model B218?
A: Yes. GWK-W40Z-LW-XL is compatible with Hyster W40Z (B218) and Hyster W45Z (C215). The kit provides direct bolt-on replacement without chassis modification. Always verify your model number on the truck nameplate before ordering to ensure correct fit.
Q: Do the 97A wheels perform better than 95A in high-wear environments?
A: Yes. The 97A durometer rating in GWK-W40Z-LW-XL significantly resists flat-spotting and edge wear on hard, smooth warehouse flooring. Testing shows 30-40 percent longer tread life compared to 95A wheels in medium to heavy-duty operations. Trade-off: 97A wheels provide slightly less cushioning and traction on wet or textured surfaces.
Q: What fastener grade is included, and why does it matter?
A: GWK-W40Z-LW-XL includes Grade 8 hex head mounting fasteners. Grade 8 bolts are heat-treated alloy steel rated for higher tensile strength and vibration resistance. Under continuous duty, standard fasteners can loosen; Grade 8 fasteners remain tight. Always inspect bolts before each shift to prevent wheel separation.
Q: How often should I inspect or replace the load wheels on this kit?
A: Inspect GWK-W40Z-LW-XL wheels monthly for flat spots, cracks, or edge wear. In heavy continuous duty, expect replacement every 12-18 months. In standard 8-hour shifts, 18-24 months is typical. Replace immediately if tread depth is less than 0.5 inches, wheels are visibly uneven, or if the truck pulls to one side during operation.
