Frequently Asked Questions
Q: What does the N suffix in GWK-PTH50-LW-N indicate?
A: The N suffix denotes the newer production type variant of the Crown PTH50 load wheel kit. GWK-PTH50-LW-N is compatible with newer-generation Crown PTH50 pallet jacks manufactured after a specific production date. The standard GWK-PTH50-LW may have slightly different bearing specifications or axle tolerances. Before ordering, verify your jack is stamped as a newer production type or confirm the serial number range with your supplier to avoid ordering an incompatible kit.
Q: Are GWK-PTH50-LW-N and GWK-PTH50-LW interchangeable?
A: GWK-PTH50-LW-N and GWK-PTH50-LW are not guaranteed interchangeable. While both fit Crown PTH50 models, the N variant is optimized for newer production jacks. Installing the wrong variant can result in loose wheel fit or axle binding. Verify your jack production date or serial range before ordering. If you are unsure which kit your jack requires, provide your serial number to your parts supplier; they can confirm the correct SKU.
Q: What are the cross-reference parts for GWK-PTH50-LW-N?
A: GWK-PTH50-LW-N is equivalent to MRK-GWK-PTH50-LW-68161142 and functionally interchanges with LWK-1106. It also cross-references to GPSN080 in Crown documentation. These alternative part numbers represent the same wheel assembly and can be used interchangeably from different distributors. Always verify the complete SKU on your purchase order matches the kit on hand to avoid installation errors.
Q: What wheel material and specifications does GWK-PTH50-LW-N provide?
A: GWK-PTH50-LW-N features ultra-polyurethane load wheels with Shore D 70 hardness and precision ball bearings. The kit includes all necessary axles and hardware for direct installation. The 70D polyurethane provides firm floor grip and extended wear life in warehouse environments. Precision ball bearings are sealed and pre-lubricated to minimize friction and reduce rolling resistance. The assembly is ready to install with no additional modifications required to your pallet jack.
Q: How do I diagnose if GWK-PTH50-LW-N wheels are worn and need replacement?
A: Worn load wheels will exhibit these symptoms: (1) flat spots or visible wear patterns on the wheel surface, (2) audible grinding or squeaking during operation, (3) reduced steering response or drifting to one side, (4) increased effort required to push the loaded jack. Inspect wheels monthly by visually checking the contact face for damage. If you observe flat spots greater than one-quarter inch deep or cracks in the polyurethane, replace the wheel assembly immediately. Do not attempt to repair or resurface sealed load wheels; replacement is the only reliable solution.
Q: What maintenance schedule is recommended for GWK-PTH50-LW-N?
A: Sealed bearing wheels require minimal maintenance. Inspect axle hardware (nuts and cotter pins) quarterly to ensure they remain tight. Clean wheel surfaces monthly to remove dirt, debris, and chemical residue that can accelerate polyurethane degradation. In food-service or wet environments, inspect bearings every three months for signs of moisture intrusion or corrosion. If a wheel begins to make noise or wobble, the bearing is likely compromised; replace the entire wheel assembly. Expected service life is 18 to 36 months under normal indoor warehouse use.
