Frequently Asked Questions
Q: What is the difference between SU 820-A and SU 820?
A: The SU 820-A is a complete load wheel assembly, meaning it comes pre-mounted with the bearing, axle, and wheel as a single unit ready for installation. The SU 820 is the wheel component only. Choose the assembly if you need a drop-in replacement or if your original bearing is damaged. Choose the wheel alone if your bearing and axle are still serviceable.
Q: Is the SU 820-A a plug-and-play replacement?
A: The SU 820-A assembly is designed as a direct replacement for lift truck load wheel assemblies with compatible mounting points. Verify that your equipment has the same axle mounting bracket and electrical clearance before installation. No modification should be required if the assembly is for the same truck model.
Q: What tools are needed to install the SU 820-A assembly?
A: Installation typically requires a socket wrench set to remove the old assembly mounting bolts and a torque wrench to tighten new fasteners to manufacturer specifications. Have the lift truck model and serial number available before starting work. Do not apply power to the truck until the assembly is fully secured and tested.
Q: How do I know if the SU 820-A assembly needs replacement?
A: Replace the assembly if the wheel will not rotate smoothly, if you hear grinding noise from the bearing, if the wheel wobbles on the axle, or if the tread is significantly worn or separated from the hub. A failing bearing will create resistance or grinding sounds and must be replaced to prevent load drop or truck instability.
Q: Can I repair the SU 820-A assembly or must I replace the entire unit?
A: Assembly replacement is typically the fastest and safest option. Individual bearing or wheel replacement depends on whether your equipment design allows disassembly. Contact your lift truck manufacturer or a certified technician to confirm if component-level repair is possible for your model. Many assemblies are sealed units and cannot be serviced.
Q: What load capacity and lifespan should I expect from the SU 820-A?
A: The SU 820-A assembly provides the same 2,000 lbs per wheel capacity as the individual SU 820 wheel. Lifespan depends on load, floor conditions, and maintenance. Expect 12 to 24 months of service in typical industrial use. Reduce load capacity in rough environments. Inspect the assembly every 6 months for wear.
