Frequently Asked Questions
Q: Is SU S673 a complete wheel assembly or a wheel only?
A: SU S673 is a wheel only, not an assembly. You must transfer your existing sealed bearing cartridge, axle spacer, and collar from your old wheel to this new one. If you do not have these components or need a ready-to-install option, order SU S673-A (complete assembly) instead.
Q: What are the dimensional specs and weight capacity of the SU S673 wheel?
A: SU S673 is 6.5 inches wide by 8 inches diameter with a 1.5 inch bore. Load capacity is 4200 pounds per wheel. Tire material is polyurethane. Overall weight is 8.2 pounds.
Q: Which bearing cartridge works with the SU S673 wheel?
A: SU S673 requires a 1.5 inch sealed roller bearing cartridge (commonly part number SU BC-1.5SR or equivalent Hyster H220451). Always purchase the bearing cartridge separately if replacing just the wheel. Do not reuse old, worn bearings.
Q: Can I use SU S673 on older lift trucks from the 1990s?
A: Possibly, but verify axle shaft diameter and the bearing cartridge type on your truck. Many 1990s models use different bore sizes or unsealed grease-packed bearings. Contact your truck manufacturer or parts supplier with your truck model and serial number before ordering SU S673.
Q: How do I diagnose if the SU S673 wheel or bearing is failing?
A: Listen for grinding, squealing, or clicking sounds during operation. Spin the wheel by hand; it should rotate smoothly for 10 to 15 seconds without noise. If you hear grinding or feel resistance, the bearing cartridge is worn. If the wheel wobbles or sits uneven, the wheel rim is damaged. Replace the affected component.
