Frequently Asked Questions
Q: What electric lift truck models is the SU 663-A load wheel assembly compatible with?
A: The SU 663-A is designed as a universal load wheel assembly for electric lift trucks and pallet jacks. Verify your truck model and serial range before ordering to confirm fitment. Check your existing wheel diameter and width dimensions against the product specifications to ensure proper replacement.
Q: How do I know if my load wheel assembly needs replacement?
A: Replace the wheel assembly if you see excessive tread wear, flat spots, chunks missing from the wheel, audible grinding or squeaking during operation, or if the wheel no longer rolls freely. These are signs of bearing wear or tread degradation. A worn wheel assembly reduces load capacity and increases operating strain on the lift truck.
Q: Is the SU 663-A wheel assembly a complete replacement or do I need the hub separately?
A: The SU 663-A is sold as a complete load wheel assembly, including the wheel, bearings, and hub. It is designed as a plug-and-play replacement. Remove the old assembly by unbolting it from the truck frame, then bolt the new assembly in place using the existing hardware.
Q: What maintenance is required for the SU 663-A after installation?
A: Inspect the wheel assembly monthly for debris, cracks, or bearing play. Keep the wheel tread clean to maintain traction. The bearings are sealed, so no periodic lubrication is required. Replace the assembly when tread depth drops below 1/8 inch or when bearing noise develops.
Q: What is the maximum load capacity for the SU 663-A wheel assembly?
A: Load capacity depends on your lift truck model and weight distribution. The SU 663-A wheel itself is engineered for standard industrial duty. Refer to your truck manual for the maximum load rating per wheel. Do not exceed the rated capacity of the truck, as overloading will shorten wheel life and damage bearings.
