LOAD WHEEL ASSEMBLY
Frequently Asked Questions
Q: What components are included in the SU S263-A load wheel assembly?
A: The SU S263-A is a complete load wheel assembly that includes the polyurethane wheel component, steel hub, and bearing. It is a ready-to-install unit that replaces the entire wheel assembly on the axle. Do not disassemble the S263-A for individual part replacement—it is engineered as an integrated unit. Verify your truck manual confirms the S263-A assembly is correct for your model before installation.
Q: Is the SU S263-A assembly equivalent to any competitor wheel assemblies from other manufacturers?
A: Without access to cross-reference databases or competitor specifications, we cannot definitively confirm equivalent assemblies from other manufacturers. Consult OEM documentation or contact the manufacturer to identify compatible alternatives. Do not assume assemblies with similar part numbers are interchangeable—hub diameter, bearing type, and wheel width must match exactly. Installing a non-compatible assembly will cause axle misalignment and steering problems.
Q: How do I install the SU S263-A assembly on my electric lift truck?
A: First, lift the truck with a hydraulic jack and support it with safety jack stands under the frame. Remove the axle retaining pin or bolt. Slide the axle out carefully and pull the old assembly off the axle. Install the new SU S263-A assembly by sliding it onto the axle, aligning the hub properly. Reinstall the axle retaining pin and secure it. Verify the wheel spins freely and does not wobble. Lower the truck and test steering before operation.
Q: What should I do if the SU S263-A assembly bearing fails during operation?
A: If the bearing fails, you cannot repair the assembly in the field. The bearing is press-fit or bonded to the hub and cannot be replaced without specialized equipment. Stop operating the truck immediately—continued use will damage the axle. Remove the failed S263-A assembly and install a new one. Have the damaged assembly serviced at a facility with bearing press equipment if you need a spare part, but do not attempt bearing replacement yourself.
Q: How often should I inspect the SU S263-A assembly for wear?
A: Inspect the S263-A assembly monthly during routine maintenance. Check for polyurethane tread wear, cracks, or missing chunks. Lift the truck and spin the wheel to confirm it rotates smoothly. Listen for grinding sounds or feel for rough spots in the bearing rotation. Confirm the wheel does not wobble laterally on the axle. If tread wear is visible, if rotation is rough, or if the wheel wobbles, plan replacement within the next service cycle to prevent bearing failure.
Q: What is the expected service life of the SU S263-A assembly?
A: The polyurethane wheel tread typically wears within 12 to 24 months under normal heavy-duty cycle use. The bearing usually outlasts the polyurethane if the assembly is not overloaded. Replace the entire S263-A assembly when the wheel tread becomes visibly flat or the bearing begins to show signs of roughness or lateral play. Do not wait until complete bearing failure—replace proactively to avoid emergency repairs and frame damage.
