Frequently Asked Questions
Q: Does the GWK-PTH50-LW replace the older 44506-001 part number?
A: Yes. GWK-PTH50-LW is a direct replacement for 44506-001 and is equivalent to K-PTH50-LW. It fits Crown PTH50 units with serial numbers #7-000000 through #7-512501. Always verify your serial range before ordering to confirm compatibility.
Q: What wheel diameter and bearing specifications does this kit include?
A: Wheel diameter is 3.00 inches with a 3.875 inch tread width and 25mm bore ID. The kit includes sealed radial bearings, steel axles, and ultra-polyurethane load wheels at 70D Shore hardness. These dimensions are engineered specifically for Crown PTH50 geometry and will not fit other models.
Q: How do I know if my Crown PTH50 load wheels need replacement?
A: Replace wheels if you observe flat spotting, cracking, severe wear streaks, or noise from the wheel assembly during operation. Spin the wheels by hand; excessive resistance or grinding indicates bearing failure. If the jack pulls to one side even on level ground, one wheel may be worn unevenly. Typical service life is 2 to 3 years under normal use.
Q: Can I use this kit on a Crown PTH50 with a different serial number range?
A: No. This kit is engineered only for units serial #7-000000 to #7-512501. Units outside this range may have different frame geometry, bearing pocket dimensions, or axle specifications. Using the wrong kit can cause misalignment, premature wear, or safety issues. Contact parts support if your serial number falls outside this range.
Q: Are the 70D Shore ultra-polyurethane wheels suitable for outdoor use?
A: 70D Shore polyurethane offers good durability for moderate indoor and light outdoor use. However, prolonged exposure to sunlight and temperature extremes can degrade polyurethane faster. Store jacks indoors when not in use. If your jack operates primarily outdoors or in high-UV environments, consider protective covering to extend wheel life.
