Frequently Asked Questions
Q: Does GWK-W50Z-LW-XL fit Hyster electric pallet trucks other than the W50Z model?
A: No. GWK-W50Z-LW-XL is engineered specifically for the Hyster W50Z model only. The 3.25-inch diameter, 4.50-inch width wheel profile and axle configuration are unique to this platform. Using this kit on other Hyster models risks improper load distribution and bearing failure. Always verify your jack nameplate matches W50Z before ordering.
Q: What symptoms indicate the GWK-W50Z-LW-XL wheels need replacement?
A: Replace wheels when you observe flat spotting, chunking, or permanent deformation on the polyurethane tread; squealing or grinding from the sealed ball bearings during operation; visible wear flats that exceed 0.25 inches; or sideways drift under load (indicating bearing wear). Check for liquid contamination on the wheels, which degrades the 95A durometer polyurethane and reduces grip.
Q: Is the GWK-W50Z-LW-XL kit a complete bolt-on replacement or does it require modification?
A: GWK-W50Z-LW-XL is a plug-and-play replacement. Remove the four case-hardened steel fasteners securing the old wheel assembly to the axle carriage, slide off the old wheels and axles, slide the new axles through the case-hardened steel core, and secure with the supplied high-strength steel fasteners. No grinding, drilling, or frame modification required. Lubrication fittings are pre-installed; grease the fittings every 40 operating hours.
Q: What is the maximum load capacity of the GWK-W50Z-LW-XL wheel kit?
A: Load capacity depends on your W50Z jack model configuration. The 95A Shore A polyurethane wheels and precision sealed ball bearings support the load rating of your specific W50Z frame. Do not exceed the jack nameplate load limit. Overloading causes accelerated wear on the polyurethane tread and bearing preload loss, typically visible within 20-30 operating hours.
Q: Can I use the GWK-W50Z-LW-XL wheels in wet or oily environments?
A: The 95A durometer polyurethane tread resists mineral oil and water splash, but prolonged immersion degrades grip and durometer hardness. In wet environments, wipe the wheels regularly and allow air drying between uses. Oil exposure reduces polyurethane elasticity; if your jack operates in a sump or oil-mist area, inspect wheels monthly for surface softening and replace if durometer loss exceeds 10 points (visually, the tread becomes tacky).
Q: How long do the sealed ball bearings in the GWK-W50Z-LW-XL kit last?
A: Sealed ball bearings are rated for 2000-3000 operating hours under normal load and maintenance. Bearing life shortens if axles are not greased per schedule, if the jack is overloaded, or if wheels hit sharp obstacles that cause impact loading. Listen for grinding or squealing; these indicate bearing preload loss. Once noise begins, replace the entire wheel assembly—individual bearing replacement is not field-serviceable on this kit.
