Frequently Asked Questions
Q: Is SU S653-A compatible with Yale and Crown electric pallet trucks?
A: SU S653-A is a polyurethane load wheel assembly designed for designated electric lift truck models only. No direct cross-reference part numbers exist for Yale, Crown, or other brands. Always verify your truck model and serial range against the OEM compatibility list before ordering. Mixing brands can cause binding, uneven wear, or load instability.
Q: What is the difference between SU S653-A and SU S653-EZ?
A: SU S653-A is a complete tandem wheel assembly with mounting hardware included. SU S653-EZ is the wheel core only, without the assembly hardware. Both are 5.000 inch diameter x 2.875 inch width. Choose SU S653-A for plug-and-play replacement; choose SU S653-EZ if you are transferring hardware from an existing wheel or need just the polyurethane tread.
Q: How do I diagnose if my load wheels need replacement?
A: Replace load wheels when you observe uneven tread wear, flat spots, cracks in the polyurethane, or reduced load capacity under normal operation. Test by lifting a known load and checking for lateral drift or wobble. If the truck pulls to one side or makes grinding noise when turning, wheel damage is likely. Inspect bore diameter (1.87 inch ID) for wear; if axle play exceeds 0.05 inch, replace the wheel.
Q: Do SU S653-A wheels require special mounting tools or modifications?
A: SU S653-A wheels mount using standard fork-mount hardware (included with assembly). No special tools are required beyond a basic wrench set. Ensure axle bolts are torqued to 15-18 foot-pounds to prevent loosening. Do not over-torque, as this can crack the thermoplastic hub. Verify axle alignment before final tightening to ensure wheels sit parallel.
Q: What load capacity does SU S653-A support?
A: Load capacity depends on your truck model and wheel configuration (tandem vs. single). SU S653-A is rated for tandem configuration. Total truck capacity is typically 3000-5500 pounds depending on the lift truck frame. Do not exceed the manufacturer rated load for your truck model. Overloading causes accelerated tread wear and bearing failure.
Q: What is the expected lifespan of SU S653-A wheels?
A: Cushothane XL polyurethane tread typically lasts 12-24 months under normal warehouse use (8-10 hours per day). Lifespan is shorter if the truck is used on rough surfaces, overloaded, or operates in cold environments below 40 degrees Fahrenheit. Inspect wheels every 500 operating hours. Store spare wheels in a cool, dry place away from direct sunlight and ozone sources to prevent premature aging.
