Frequently Asked Questions
Q: What is the SU S854-XL-A and how does it differ from SU S854-XL?
A: The SU S854-XL-A is a complete wheel assembly combining the SU S854-XL extra-load polyurethane wheel with a pre-assembled hub, bearing, and fastening hardware. The SU S854-XL is the wheel elastomer only. The SU S854-XL-A is ready to install directly onto your lift truck axle without additional assembly or modification. Order SU S854-XL-A for a complete replacement wheel assembly; order SU S854-XL only if you are rebuilding an existing hub and bearing.
Q: What tools and steps are required to install the SU S854-XL-A?
A: Install the SU S854-XL-A by lifting the truck safely on a jack stand. Remove the old wheel assembly by unbolting the axle fastener. Slide the new SU S854-XL-A assembly onto the axle spindle, ensuring the bore sits fully on the bearing. Install a new axle bolt (do not reuse old hardware) and tighten to 40-60 foot-pounds using a calibrated torque wrench. Spin the wheel by hand to verify smooth rotation and proper bearing fit. Lower the truck and test operation.
Q: Is the SU S854-XL-A suitable for freezer and wet environment operation?
A: Yes. The SU S854-XL-A uses extra-load Cushothane XL material that maintains better flexibility in cold environments compared to standard compound. Operating temperature range is minus 20 to plus 130 degrees Fahrenheit. In freezer conditions (below minus 10 degrees Fahrenheit), the wheel will harden slightly; inspect regularly for cracking and verify bearing rotation remains smooth. The sealed bearing design resists water intrusion in wet environments. Expected service life in freezer operation is 12-20 months.
Q: How do I verify the SU S854-XL-A is compatible before installation?
A: The SU S854-XL-A has a 2.25 inch bore diameter and 2.875 inch tread width designed for standard lift truck configurations. Before ordering, verify your truck axle spindle diameter is 2.25 inches and the original wheel width is 2.875 inches. Check your truck manual or consult your manufacturer with the serial number. Measure the existing wheel bore if uncertain. Bore diameter mismatch will prevent installation and create safety hazards.
Q: What is the expected service life and maintenance interval for the SU S854-XL-A?
A: The SU S854-XL-A assembly typically operates 15-30 months in normal warehouse conditions, longer than standard SU S854-A due to extra-load material formulation. Inspect wheels monthly for tread wear, cracking, and bearing play. Replace when tread depth reaches 50 percent of original (approximately 0.25 inch). The bearing cannot be serviced separately; replace the entire assembly if bearing wear is detected. In heavy-duty continuous use, service life may be reduced to 12-18 months.
Q: Can the SU S854-XL-A wheel assembly be refurbished or repaired?
A: No. The SU S854-XL-A cannot be refurbished. Polyurethane wheels cannot be re-tread or resurfaced. Damaged bearings cannot be serviced; the entire assembly must be replaced. Do not attempt to weld, machine, or heat-treat the assembly. Do not reuse fasteners from old assemblies. Once tread wear reaches replacement threshold or bearing damage occurs, order a new SU S854-XL-A assembly. Used assemblies cannot be re-sold due to bearing life uncertainty.
