Frequently Asked Questions
Q: What is included in the SU 671-A load wheel assembly?
A: The SU 671-A is a complete wheel assembly that includes the load wheel, steel hub, sealed bearings, and all fasteners needed for installation. It is a ready-to-install replacement. Simply unbolt the old assembly from your lift truck frame and bolt the new SU 671-A in place using the existing mounting hardware.
Q: How is the SU 671-A different from ordering the SU 671 wheel alone?
A: The SU 671 is the wheel component only. The SU 671-A includes the wheel plus the hub and sealed bearings as an integrated assembly. If your hub and bearings are worn or damaged, you must order the SU 671-A. If only the wheel tread is worn and the hub and bearings are good, you can reuse your existing hub and order just the SU 671 wheel. Always verify hub condition before choosing.
Q: What tools are required to install the SU 671-A assembly on an electric lift truck?
A: Installation requires basic hand tools: a wrench or socket set matching your truck bolt sizes, a floor jack or hoist to lift the truck, and jack stands for safety support. The specific bolt size depends on your lift truck model. Consult your truck manual for the correct fastener size. Do not operate the truck while it is on jack stands alone; always use proper support and lock the brakes.
Q: Does the SU 671-A assembly require any adjustment or alignment after installation?
A: The SU 671-A is designed as a plug-and-play replacement with no adjustments required after installation. Ensure the assembly is seated fully on the mounting bolts and torque all fasteners to the specifications in your truck manual. After installation, test the wheel by rotating it by hand to confirm smooth spinning and no binding. Check steering response during a test drive.
Q: How often should the SU 671-A assembly be inspected for maintenance or wear?
A: Inspect the wheel assembly monthly for debris, cracks, or visible damage. Check bearing condition quarterly by spinning the wheel and listening for grinding noise or feeling for resistance. Monitor tread depth and replace the assembly when wear reaches 1/8 inch. If the wheel makes noise or does not spin freely, do not delay replacement. Worn wheels affect load stability and increase operator risk.
