Frequently Asked Questions
Q: What is the load capacity and wheel diameter of the SU 671-XL?
A: The SU 671-XL is rated for 1,500 lbs per wheel with a 6-inch diameter polyurethane tread. Maximum fleet load is 6,000 lbs across all four wheels. Do not exceed rated capacity as it will damage the bearing and cause premature tread wear.
Q: Is the SU 671-XL compatible with Toyota 8FGKU25 and Hyster S50FT forklifts?
A: The SU 671-XL fits Toyota 8FGKU25 models from 2010 onward. It is not compatible with Hyster S50FT without a hub adapter. If you have a Hyster, use part number SU 671-XL-HY instead. Always verify your forklift model and serial range before ordering.
Q: How do I diagnose if the SU 671-XL wheel bearing is failing?
A: Listen for a grinding or squealing noise when the truck is moving. Check for excessive play by rocking the wheel side to side by hand. If the wheel has more than 0.25 inches of lateral movement or the tread is cracked, replace the wheel immediately. Do not continue operating as bearing failure can cause the wheel to lock or separate.
Q: What tools are required to install the SU 671-XL wheel?
A: You need a 17mm socket, a hex key set, and a tire lever. Remove the retaining clip with the hex key, slide the old wheel off the axle, and slide the new wheel on. Reattach the clip and tighten to 25 ft-lbs torque. Installation takes about 10 minutes per wheel and does not require jacking the truck.
Q: How often should the SU 671-XL wheel be inspected for maintenance?
A: Inspect every 250 operating hours or monthly, whichever comes first. Check tread depth and lateral play. Clean polyurethane tread with mild soap and water to remove debris. Bearing lubrication is sealed and does not require re-oiling. Average wheel lifespan is 2,000 to 3,000 operating hours depending on load and floor conditions.
Q: Can I interchange SU 671-XL with SU 671-XL-A assembly?
A: No. The SU 671-XL is the wheel only. The SU 671-XL-A includes the wheel, bearing, axle cartridge, and mounting hardware as a complete assembly. Use SU 671-XL-A only if you need to replace the entire wheel assembly. If only the tire is damaged, replace with SU 671-XL wheel alone.
