Frequently Asked Questions
Q: What load capacity does the GWK-PR4500-LW-XL support?
A: The GWK-PR4500-LW-XL is rated for 6000 to 8000 lb capacity at a 24 inch load center, designed for Crown PR 4500 Series electric rider pallet trucks. The 97A Shore A polyurethane wheels, sealed precision bearings, hardened steel axle, and grade 8 fasteners are engineered to handle this load range safely. Do not exceed 8000 lbs or use a load center beyond 24 inches; failure to comply risks wheel failure, axle bending, and unsafe load handling.
Q: How does the 97A durometer differ from the standard 95A wheels in the GWK-PR4500-LW?
A: The 97A Shore A hardness is 2 points stiffer than the 95A standard wheels, providing superior wear resistance and lower rolling resistance. This results in less polyurethane compression, reducing heat buildup during long shifts and extending wheel life in high-mileage environments. The trade-off is slightly firmer handling and a small increase in steering effort. The XL variant is recommended for outdoor loading docks, rough concrete, or trucks running 12 plus hour shifts daily.
Q: What tools are required to install the GWK-PR4500-LW-XL, and do I need special training?
A: You will need a hydraulic floor jack rated for at least 8000 lbs, safety stands, wrenches or socket set for fasteners, and a torque wrench to tighten grade 8 fasteners to specification (typically 45 to 65 ft-lbs depending on fastener size). Installation takes 45 to 60 minutes per wheel pair. No special training is required, but you must follow all safety procedures: never work under the truck without safety stands, and do not exceed specified torque values. Consult your truck manual for exact torque and fastener specifications.
Q: Can I upgrade from GWK-PR4500-LW standard wheels to GWK-PR4500-LW-XL wheels on an existing truck?
A: Yes, the GWK-PR4500-LW-XL wheels are a direct upgrade for any Crown PR 4500 truck currently running standard wheels. The axle, bearings, and fasteners in the XL kit are also upgraded (hardened steel axle, grade 8 fasteners) to support extended durability. Uninstall the old kit, install the new XL kit using the same mounting points, and torque fasteners to specification. The truck will handle identical loads but with improved wheel longevity and lower maintenance.
Q: How often should the sealed precision bearings be inspected or re-greased?
A: The sealed precision bearings are pre-lubricated and closed, requiring no manual re-greasing during the service life of the kit. Inspect bearings monthly for noise, grinding, or resistance when rotating the wheel by hand. If you hear grinding or feel resistance, bearings have failed internally and the entire kit must be replaced. Do not attempt to open or service sealed bearings; replacement is the only repair option. Properly maintained bearings typically last as long as the wheel polyurethane, 24 to 36 months in high-use environments.
