Frequently Asked Questions
Q: What is included in the SU S9812-EZ-A load wheel assembly?
A: The SU S9812-EZ-A is a complete pre-assembled unit consisting of the 3.25 inch diameter by 6.01 inch width load wheel bonded to a hub assembly with integrated bearings. It is ready to install directly onto your lift truck spindle shaft. The assembly includes all internal components needed for operation, eliminating the need for separate bearing installation or hub bonding.
Q: Can I install the SU S9812-EZ-A assembly myself or do I need a technician?
A: Installation is straightforward for trained personnel. Remove the retaining clip or cotter pin from the spindle shaft, slide the old wheel assembly off, and slide the SU S9812-EZ-A assembly onto the shaft. Secure with a new retaining clip or cotter pin and ensure it spins freely without wobbling. No special tools are required beyond a clip removal tool. Most installations take less than 15 minutes per wheel.
Q: What is the difference between SU S9812-EZ-A and SU S9812-EZ?
A: SU S9812-EZ is a wheel only. SU S9812-EZ-A is a complete wheel assembly that includes the wheel bonded to a hub and bearing assembly. If you need just the wheel for replacement on an existing hub, order SU S9812-EZ. If you need a full plug-and-play wheel assembly ready to install, order SU S9812-EZ-A.
Q: Are the bearings in the SU S9812-EZ-A assembly sealed or open?
A: The SU S9812-EZ-A assembly includes sealed ball bearings that require no external lubrication. The seals protect against dirt and moisture infiltration. If the assembly starts making noise or spinning becomes rough, the bearing seals may have failed and the assembly should be replaced. Do not attempt to re-lubricate sealed bearings as this can damage the seals.
Q: Does the SU S9812-EZ-A work on both load and steering wheels?
A: The SU S9812-EZ-A is designed specifically for load wheel (driven wheel) applications. It is not suitable for steering wheels, which have different bearing requirements and spindle designs. Using this assembly on a steering spindle will cause improper handling and safety hazards.
Q: What happens if the SU S9812-EZ-A wheel assembly gets damaged on the spindle?
A: If the wheel develops flat spots, cracking, or the assembly develops lateral play or noise, it must be replaced as a unit. The wheel and hub are bonded together using proprietary technology and cannot be separated for repair. A damaged assembly compromises lift truck stability and operator safety. Order a replacement SU S9812-EZ-A and install using the standard removal and installation process.
