Frequently Asked Questions
Q: What makes GWK-WPX45-LW-XL different from the standard GWK-WPX45-LW?
A: The XL variant features 97A Shore durometer wheels versus 95A in the standard model. The XL wheels are also larger at 3.25 x 4.50 inches. This provides superior traction, faster speed capability, and longer wear life. Choose XL if your warehouse has high-traffic floors, contaminated surfaces, or demanding load cycles.
Q: Is installation of GWK-WPX45-LW-XL plug-and-play?
A: Yes. This is a direct bolt-on replacement kit. It includes dual-wheel assemblies with integrated roller bearings, hardened steel axles, and mounting hardware. No disassembly or special tools are required beyond a socket set. Installation time is typically 30-45 minutes per wheel set.
Q: Will the larger wheel size affect truck height or clearance?
A: Yes, the 3.25 x 4.50 inch wheels are larger than standard wheels, which slightly increases truck ride height. Measure your facility door frames and racking clearance before ordering. In most warehouses this is not an issue, but low-ceiling areas or tight aisle racking may be affected. Consult Clark specifications for your WPX45 model.
Q: What is the 97A Shore durometer rating optimized for?
A: 97A polyurethane is engineered for high-traffic warehouse environments with contaminated floors (oil, grease, water). The harder durometer resists cutting and flat spotting better than 95A. It is ideal for heavy-use operations, outdoor ramps, or facilities with aggressive floor conditions. Trade-off: slightly reduced cushioning on rough surfaces.
Q: How do I diagnose if my wheels have failed and need replacement?
A: Replace wheels immediately if you observe cracks, chunks missing from the wheel surface, flat spotting on one side, wheel wobble during operation, or the truck drifts to one side when traveling straight. These indicate bearing failure or polyurethane degradation. Do not operate loaded trucks with failed wheels as they compromise load control and operator safety.
Q: What is the expected service life of GWK-WPX45-LW-XL wheels?
A: In normal warehouse conditions (8-hour daily use), expect 3-5 years of service. Heavy-use environments (16+ hours daily, contaminated floors) may see 2-3 years. Proper maintenance—monthly inspections, floor cleanliness, and bearing lubrication per manufacturer guidelines—extends lifespan significantly. Replace proactively before wheels degrade and damage bearings.
