Frequently Asked Questions
Q: What vehicles does the SU S631-XL-A Load Wheel Assembly fit?
A: The SU S631-XL-A is an XL-capacity assembly designed for Yale, Hyster, and Jungheinrich electric pallet jacks and walkie stackers rated 4000-6000 lbs. Always verify the serial number range on your truck before ordering to confirm compatibility.
Q: Is the SU S631-XL-A a complete wheel assembly or does it require additional parts?
A: The SU S631-XL-A is a complete assembly that includes the wheel, bearing, axle bracket, and hardware. Installation requires only basic wrenches and typically takes 15-20 minutes per wheel. No modifications to the truck frame are needed.
Q: What is the load capacity and wheel diameter of the SU S631-XL-A?
A: The SU S631-XL-A supports up to 6000 lbs per wheel pair and features an 8-inch diameter polyurethane wheel. Do not exceed rated capacity as this will cause premature bearing failure and wheel degradation.
Q: How often should I inspect or replace the SU S631-XL-A assembly?
A: Inspect the assembly every 500 operating hours for wear, flat spots, and bearing noise. Replace when wheels show visible cracking, the polyurethane thickness reduces below 0.5 inches, or bearings produce grinding sounds. Average lifespan is 3-5 years with standard warehouse use.
Q: Can I replace just the wheel on the SU S631-XL-A or must I replace the entire assembly?
A: The wheel is bonded to the assembly and cannot be replaced separately. You must replace the entire SU S631-XL-A assembly. Attempting to remove the wheel will damage the axle bracket and bearing hub.
