Frequently Asked Questions
Q: What is the SU 820-EZ-A and how does it differ from the SU 820-EZ wheel?
A: The SU 820-EZ-A is a complete load wheel assembly with the EZ designation, meaning it comes pre-assembled with bearing, axle, and mounting hardware. The SU 820-EZ is the wheel component alone. The assembly is ready to install as a unit, while the wheel requires a compatible axle and bearing setup.
Q: Is the SU 820-EZ-A a one-to-one replacement for my truck wheels?
A: The SU 820-EZ-A is a direct replacement only if your equipment matches the assembly mounting specification. Check your lift truck model number, serial range, and original equipment specifications before ordering. Do not mix assembly types on the same truck. All wheels should be identical to ensure balanced load distribution.
Q: What tools and safety precautions are needed to install the SU 820-EZ-A assembly?
A: You will need a socket wrench set, torque wrench, and jack or lift to access wheel mounting points. Ensure the truck is powered off and cannot move during installation. Tighten all fasteners to manufacturer torque specifications. Test wheel rotation after installation before operating the truck. Do not work under a truck supported only by a jack.
Q: How do I troubleshoot the SU 820-EZ-A assembly if it stops rotating?
A: Spin the wheel by hand to determine if the bearing or wheel tread is damaged. Grinding noise indicates bearing failure. Flat spots or separated tread indicate wheel damage. A stuck assembly usually means bearing seizure and requires assembly replacement. Do not attempt to lubricate a stuck bearing as the assembly must be replaced as a unit.
Q: Can I service individual components of the SU 820-EZ-A assembly?
A: Most sealed assemblies cannot be disassembled for component repair. The bearing, wheel, and axle are integrated as a single unit. If any component fails, the entire assembly must be replaced. Check with your equipment manufacturer to confirm if bearing-only or wheel-only replacement is possible for your truck model.
Q: What is the warranty and expected service life of the SU 820-EZ-A assembly?
A: Service life typically ranges from 12 to 24 months in normal industrial use. Warranty terms depend on the manufacturer. Reduced service life occurs in high-load applications, rough floors, or outdoor environments. Inspect the assembly every 6 months. Track load hours to anticipate replacement needs and avoid unexpected downtime.
