Frequently Asked Questions
Q: What is included in the SU S353-A poly load wheel assembly?
A: The SU S353-A is a complete assembly containing the 5 inch x 3.625 inch polyurethane load wheel, sealed bearing, hub, and all fastening hardware. No additional bearing or hub installation is required; bolt it directly to your axle after removing the old assembly.
Q: Can I replace just the wheel on an SU S353-A, or must I replace the entire assembly?
A: If the bearing is good and the hub is not damaged, you can use the SU S353 bare wheel and reinstall the existing bearing and hub. However, if the bearing shows noise or play, replace the entire SU S353-A assembly. Mixing old bearings with new wheels often leads to premature failure.
Q: What is the installation procedure for the SU S353-A assembly?
A: Lift the truck and secure it on blocks. Remove the axle nut and slide off the old wheel assembly. Clean the axle shaft. Slide the SU S353-A onto the axle, align the hub, and torque the axle nut per the truck manual (typically 40 to 80 foot-pounds). Verify the wheel spins freely and lock the safety pin in place.
Q: How often should I inspect the SU S353-A assembly in service?
A: Inspect monthly for bearing noise, play, or seepage. Check the polyurethane tread for cracks, flat spots, or wear. If the wheel no longer spins smoothly or makes grinding sounds, the bearing has failed. Replace the assembly immediately; do not attempt to repack sealed bearings.
