Frequently Asked Questions
Q: What is included in the SU S666-EZ-A assembly kit?
A: SU S666-EZ-A is a complete load wheel assembly that includes the 6 x 4 Cushothane EZ tire, the hub with integrated bearing, the bore adapter if needed, and factory-installed lubrication. This is a ready-to-mount component that does not require separate bearing installation. Install directly onto your lift truck axle shaft.
Q: Is the SU S666-EZ-A a drop-in replacement for standard 6 x 4 wheel assemblies?
A: Yes, if your truck currently uses a 6 x 4 wheel with a 2.5 inch bore. The SU S666-EZ-A is a direct bolt-on replacement. However, if your truck uses a different wheel size or bore dimension, this assembly will not fit. Measure your existing wheel to confirm outer diameter, width, and bore size before ordering.
Q: How do I install the SU S666-EZ-A and what tools do I need?
A: You will need a wheel puller, a jack stand, and a wrench or socket for the axle nut or retaining clip. Lift the truck, remove the old wheel assembly, slide SU S666-EZ-A onto the axle shaft, align the hub bore, and secure the retaining hardware. Torque the axle nut to 40 to 60 foot-pounds. No special bearing tools are required.
Q: What maintenance is required after installing SU S666-EZ-A?
A: Inspect the wheel for debris or damage monthly. Spin the wheel by hand after installation to verify smooth operation. Establish a re-lubrication schedule per your truck manual, typically every 500 to 1000 hours of operation. Monitor for squeaking or grinding sounds which indicate bearing wear. Replace the bearing assembly if noise develops.
Q: Will the SU S666-EZ-A work on floors that are wet or oily?
A: Cushothane EZ is designed for dry, indoor warehouse environments and provides less traction on wet or oily floors. If your truck operates on wet floors, consider switching to a rubber wheel with higher traction. Test the SU S666-EZ-A on a test area first if floor conditions are variable. Always prioritize traction and operator safety.
