Frequently Asked Questions
Q: Can I use SU S653-EZ wheel cores on my existing wheel assemblies?
A: Yes, SU S653-EZ is a core-only wheel compatible with standard tandem configurations. Your existing axle bolts, washers, and hub hardware must match the 1.87 inch bore diameter. Measure your current wheel bore before ordering. If bore diameter or bolt pattern differ, you need the complete assembly (SU S653-A) instead. Reusing old hardware with new cores is safe if hardware shows no corrosion or bending.
Q: What are the exact dimensions of SU S653-EZ, and does it fit standard forks?
A: SU S653-EZ is 5.000 inch outer diameter x 2.875 inch width (127mm x 73.02mm metric). Hub bore is 1.87 inch ID with 0.591 inch bore depth and 2.045 inch bore outer diameter. These dimensions follow standard tandem wheel specs and fit any electric lift truck designed for 5-inch tandem wheels. Verify your fork or axle width is exactly 2.875 inches to prevent binding.
Q: Is SU S653-EZ compatible with SU S653-A assemblies?
A: Both use the same polyurethane tread material and core dimensions. SU S653-EZ is the wheel core only; SU S653-A includes the complete assembly with hardware. You cannot mix and match. If you have an SU S653-A assembly on your truck, order SU S653-A replacements. If you already have axles and hardware, SU S653-EZ cores save cost, but only if your existing hardware matches the 1.87 inch bore spec.
Q: How do I remove and install SU S653-EZ wheel cores?
A: To remove: Lift the truck on a safe stand. Remove axle bolts using a wrench. Slide the old wheel core off the axle. Clean the axle of debris and corrosion. To install: Slide SU S653-EZ core onto the clean axle, ensuring the bore seats fully. Align wheel perpendicular to the fork. Insert and tighten axle bolts to 15-18 foot-pounds. Recheck alignment after 8 operating hours.
Q: What happens if I install SU S653-EZ on an axle with wrong bore diameter?
A: The wheel will rock, bind, or slip on the axle, causing uneven load distribution, rapid tread wear, and steering problems. A loose wheel can fall off during operation, creating a safety hazard. Always verify bore diameter (1.87 inch ID) and axle diameter before installation. If your truck has a different bore size, you need a different wheel core, not SU S653-EZ.
Q: How long does SU S653-EZ polyurethane tread last?
A: Cushothane XL tread lasts 12-24 months under normal 8-10 hour daily operation in climate-controlled warehouses. Harsh conditions (outdoor use, freezing weather, rough floors, overloading) reduce lifespan to 6-12 months. Inspect tread for cracks, flat spots, and separation from the core every 500 hours. Once tread depth reduces by 50 percent or tread separates, replace the core.
