Frequently Asked Questions
Q: What does the SU S854-A include and how is it different from SU S854?
A: The SU S854-A is a complete load wheel assembly that includes the Cushothane XL polyurethane wheel (5.000 inch OD by 2.875 inch width), the hub, bearing, and fastening hardware. The SU S854 is the wheel elastomer only. The SU S854-A is ready to install directly onto your lift truck axle. Order SU S854-A if you need a complete replacement; order SU S854 only if you are rebuilding a wheel assembly.
Q: Is the SU S854-A a plug-and-play replacement or does installation require modifications?
A: The SU S854-A is plug-and-play for trucks originally equipped with this assembly or equivalent 5.000 inch OD wheels with 2.25 inch bore diameter. Simply remove the old assembly by unbolting the axle, slide the new assembly onto the spindle, and reinstall the fastener. Do not drill or modify the truck frame. If your truck has a different bore diameter or requires special spacers, the SU S854-A will not fit without modification.
Q: What torque specification should I use when installing the SU S854-A?
A: Tighten the axle fastener to 40-60 foot-pounds of torque using a calibrated torque wrench. Over-tightening (exceeding 80 foot-pounds) can damage the bearing and crack the hub. Under-tightening (below 30 foot-pounds) will cause the wheel to wobble and loosen during operation. Always use a new axle bolt; reused bolts may not maintain proper tension. Verify the fastener size and material grade with your truck manufacturer before installation.
Q: How can I verify the SU S854-A is compatible with my lift truck before ordering?
A: Check your truck model, serial number, and existing wheel specifications. Measure the wheel bore diameter (should be 2.25 inch inside) and tread width (2.875 inch). Look at the original part number on the wheel hub or consult your service manual. Contact your truck manufacturer with the serial number to confirm wheel compatibility. Never assume wheels are interchangeable between brands or model years.
Q: What is the expected service life of the SU S854-A assembly?
A: The SU S854-A wheel assembly typically lasts 12-24 months in normal warehouse use. Heavy-duty, continuous use in distribution centers may reduce life to 6-12 months. Freezer environment operation may extend life due to lower activity but increases brittleness risk. Regular inspection monthly (tread wear, bearing play, damage) will alert you to replacement need. The bearing assembly cannot be serviced separately; the entire wheel must be replaced when bearing wear is detected.
Q: Can the SU S854-A wheel be stored for extended periods, and how?
A: Yes. Store the SU S854-A indoors in a cool, dry location (50-70 degrees Fahrenheit, below 60 percent humidity) away from direct sunlight, heat, and oil or solvents. Do not store in freezer or outdoor areas. Stack no more than 4 assemblies high to prevent hub or bearing damage. Keep protective caps on the bore to prevent contamination. Properly stored, the assembly maintains integrity for 3-5 years before installation.
