Frequently Asked Questions
Q: What makes the SU 673-EZ different from the standard SU 673 wheel?
A: The SU 673-EZ has a quick-change axle design that eliminates the need for pliers to remove and install the E-clip. The wheel slides on and off with hand pressure only. Installation time is reduced to 2 to 3 minutes per wheel. The load rating and bearing performance are identical to SU 673.
Q: Is the SU 673-EZ compatible with Crown and Hyster pallet jacks?
A: The SU 673-EZ fits Crown RC 5500 and most Crown manual pallet jacks with 0.75-inch diameter axles. Hyster compatibility depends on the model. Verify your axle diameter and pocket width before ordering. If your jack has a different axle size, the SU 673-EZ will not fit without modification.
Q: How do I diagnose if the SU 673-EZ bearing is failing?
A: Lift the jack so the wheel clears the floor. Spin the wheel by hand and listen for grinding or squealing. Check for lateral play by pulling the wheel toward and away from the frame. If you feel movement greater than 0.25 inches or hear noise, the bearing is worn. Replace the wheel immediately to prevent wheel lockup during use.
Q: What is the correct procedure to install and remove the SU 673-EZ?
A: To install: Lift the jack 2 inches off the floor. Push the new SU 673-EZ wheel onto the axle with firm hand pressure until it seats. To remove: Apply firm hand pressure and pull the wheel straight off the axle. Do not twist or rock the wheel as this can damage the quick-change collar. Lubrication of the axle collar is not needed.
Q: How often should SU 673-EZ wheels be maintained and what is their lifespan?
A: Inspect every 200 operating hours or monthly. Clean the polyurethane tread with a damp cloth to remove dust. Check that the quick-change collar spins freely and shows no cracks. The sealed bearing requires no lubrication. Average service life is 1,500 to 2,500 operating hours. Replace when tread depth is less than 0.25 inches or the bearing shows play.
Q: Can I use SU 673-EZ outdoors and does weather affect the quick-change mechanism?
A: The SU 673-EZ is rated for indoor warehouse use only. The polyurethane tread will degrade and wear faster outdoors. The quick-change collar is not sealed and can corrode if exposed to rain or salt. If your jack is used outdoors, remove the wheel and store it indoors when not in use. Outdoor use voids the warranty.
