Frequently Asked Questions
Q: What is the SU 9871-EZ and how does it differ from the SU 9871-A?
A: The SU 9871-EZ is an aftermarket load wheel from Superior. The EZ designation may indicate an easy-to-install variant, simplified bearing design, or different tread material compared to the SU 9871-A. Contact the parts supplier to confirm the exact differences in specifications, wheel diameter, load rating, and bearing type between the two models. Use only the part number specified for your pallet jack model.
Q: Is the SU 9871-EZ a direct replacement for my electric pallet jack?
A: The SU 9871-EZ is designed for electric pallet jack applications. Compatibility depends on your specific jack model, axle diameter, and wheel mounting configuration. Provide your pallet jack manufacturer, model number, and serial range to the parts supplier to confirm fitment. Do not install without verified cross-reference, as incorrect wheel sizes will not fit and can damage the axle assembly.
Q: Does the SU 9871-EZ include bearings and mounting hardware?
A: Confirm whether the SU 9871-EZ is a wheel-only component or a complete assembly with integrated bearings and hardware. The product description and packaging will indicate what is included. If you are transferring bearings from an old wheel, follow the proper bearing installation procedures and apply appropriate lubrication. Contact the supplier if component details are unclear.
Q: What is the installation procedure for the SU 9871-EZ?
A: If the SU 9871-EZ is a complete assembly, remove the axle retaining pin or clip, slide out the old wheel, position the SU 9871-EZ onto the axle, and resecure the fastener. If it is a wheel-only component, you may need to transfer bearings from the old wheel using a bearing press or contact a service technician. Consult the installation documentation or supplier support for your specific jack design.
Q: What load capacity is the SU 9871-EZ rated for?
A: Static load rating for the SU 9871-EZ is specified in the product technical data. Verify the per-wheel load limit before installation. Operating the pallet jack above the specified load capacity will accelerate bearing wear and shorten wheel life. For electric jacks with multiple load wheels, confirm the total platform load does not exceed the combined wheel capacity.
Q: How do I diagnose if my SU 9871-EZ wheel is failing and needs replacement?
A: Replace the SU 9871-EZ if the wheel produces grinding or squeaking sounds during operation, shows visible flat spots or damage to the tread, exhibits excessive play or wobble on the axle, or the pallet jack becomes difficult to maneuver. Spinning the wheel by hand should be smooth and effortless. A failing wheel assembly reduces performance and can damage the frame if not replaced promptly.
