Load Wheel Assembly
Frequently Asked Questions
Q: What components are included in the SU S9820-A load wheel assembly?
A: The SU S9820-A is a complete wheel assembly consisting of the SU S9820 poly wheel, hub, pre-installed bearings, and all fasteners and hardware needed for direct axle installation. It arrives fully assembled and ready to mount; no field pressing or bearing adjustment is required.
Q: What electric lift trucks are compatible with the SU S9820-A assembly?
A: The SU S9820-A assembly is designed for electric pallet jacks, stackers, and powered lift trucks that use this specific wheel assembly size and mounting pattern. Verify compatibility with your truck model, serial number, and axle specifications before ordering. Contact us with truck details if you are unsure whether this assembly fits your equipment.
Q: How long does it take to install the SU S9820-A assembly compared to replacing just the wheel?
A: Installing the SU S9820-A assembly typically takes 20-30 minutes: raise the truck, remove old fasteners, pull the old assembly, slide the new assembly onto the axle, align holes, torque fasteners to 35-45 ft-lbs, and lower the truck. Replacing just the SU S9820 wheel (without the assembly) takes 1-2 hours because it requires hub removal, pressing the new wheel onto the hub, bearing adjustment, and reassembly. The assembly is faster and eliminates pressing errors.
Q: Do the bearings in the SU S9820-A assembly come pre-lubricated?
A: Yes. The SU S9820-A includes factory-installed, pre-lubricated bearings that require no field lubrication during the first year of operation. After one year or every 500 operating hours (whichever comes first), refer to your lift trucks maintenance manual for relubrication intervals. Do not over-grease. Use only the grease type specified in your truck manual to avoid bearing damage.
Q: What is the load rating of the SU S9820-A assembly?
A: The SU S9820-A assembly is rated for your lift trucks maximum design load as specified on the trucks nameplate. The assembly will not increase your trucks load capacity. Load rating is determined by the weakest link in the drive train (typically the axle or frame). Do not exceed your trucks rated capacity. Overloading voids warranty and damages bearings, wheels, and axles.
Q: How often should the SU S9820-A assembly be replaced during the life of the truck?
A: Expected lifespan is 12-24 months under typical 8-hour daily operation. Replace the assembly when the wheel tread is worn flat, chunks appear in the polyurethane, the wheel wobbles during operation, or you hear grinding or resistance. Do not attempt to replace just the wheel while keeping the hub; replace the entire assembly for consistent performance and bearing condition. Plan budget for replacement every 18 months under continuous use.
