Frequently Asked Questions
Q: What does GWK-PTH50-CK replace, and is there a superseded part number?
A: GWK-PTH50-CK supersedes part number 150-0351. It is also equivalent to OEM part K-PTH50-CK. If you have old paperwork or a work order referencing 150-0351, order GWK-PTH50-CK as the current replacement. The newer part number reflects design updates to bearing retention and axle tolerance, both of which improve durability and reduce slack over the product lifecycle.
Q: Will GWK-PTH50-CK fit all Crown PTH50 models?
A: GWK-PTH50-CK is designed for newer Crown PTH50 pallet jacks. Verify your machine serial number on the frame nameplate before ordering. If your PTH50 is early production or a special variant, compare your wheel bore diameter (should be 20mm for standard PTH50) and axle length (typically 8.5 to 9 inches) against the kit specifications. Contact your supplier with your serial number if you are uncertain.
Q: What is included in the GWK-PTH50-CK complete wheel kit?
A: GWK-PTH50-CK includes two complete load roller assemblies (70D ultra-polyurethane wheels with bearings), two complete steer wheel assemblies (polyurethane wheels with bearings), zinc-plated steel axles for both load and steer positions, high tensile snap rings, and all fasteners (bolts, nuts, washers). No additional hardware is required for installation. The kit covers all four wheels on a standard PTH50 pallet jack.
Q: How do I diagnose if my PTH50 wheels need replacement versus repair?
A: Inspect for metal-on-floor contact (polyurethane completely worn away), flat-spotting greater than one-quarter inch across the wheel face, visible cracks in the wheel, or bearing drag or rattling. If flat-spotting is minor or surface abrasion only, wheels can be reconditioned by a specialist. If bearing play exists, the wheel assembly must be replaced entire units do not rebuild. Replace the full GWK-PTH50-CK kit every 18 to 24 months under normal use.
Q: What is the rated load capacity for GWK-PTH50-CK?
A: GWK-PTH50-CK is rated for the standard Crown PTH50 capacity of 5000 lb at a 24 inch load center. The 70D load wheels and polyurethane steer wheels are engineered to support this load without deformation. Do not exceed the jack nameplate rated capacity. Overloading accelerates wheel wear and can cause permanent set or cracking in the polyurethane material.
Q: Can I install GWK-PTH50-CK myself, or do I need factory service?
A: GWK-PTH50-CK installation is straightforward for trained technicians but requires basic mechanical skills and tools. You need a socket wrench set, snap ring pliers, and possibly a bearing driver if axles must be pressed. Installation takes 60 to 90 minutes for all four wheels. If your technicians lack bearing installation experience, send the jack to factory service or an authorized technician. Improper bearing installation can cause premature failure.
