Frequently Asked Questions
Q: What is the difference between the SU S911 and the SU S9109-XL-A?
A: The SU S911 is a load wheel only, whereas the SU S9109-XL-A is a complete wheel assembly that includes the hub. The SU S911 wheel is typically used as a replacement tread or when rebuilding an assembly with an existing hub. Verify your truck design before ordering to determine whether you need a wheel or a full assembly.
Q: Can the SU S911 wheel be used on different hub types?
A: The SU S911 wheel bore diameter and hub interface must match your existing hub exactly. Hub bore sizes vary by model. If you do not know your hub bore size, measure the hub opening or reference your truck manual. Forcing a mismatched wheel onto a hub will cause installation failure and unsafe operation.
Q: How do I remove and replace the SU S911 load wheel?
A: Secure the truck and remove the axle pin or fastener. Slide the worn wheel off the axle or hub shaft. Clean any debris from the hub bore and shaft. Slide the SU S911 wheel onto the hub, ensuring it seats flush against the hub face. Reinstall the axle fastener and tighten securely. Do not operate the truck until the fastener is confirmed tight.
Q: What symptoms indicate that the SU S911 wheel needs replacement?
A: Replace the SU S911 wheel if you observe flat spots, cracks, chunks missing from the tread, uneven wear, or tread depth less than 0.25 inches. Also replace if the wheel has hardened, cracked, or is no longer making full ground contact. These conditions reduce traction and increase stopping distance, creating a safety hazard.
Q: Is the SU S911 wheel compatible with outdoor or wet-floor applications?
A: The SU S911 is designed primarily for indoor warehouse use on dry floors. Outdoor use, wet surfaces, or exposure to oil and chemicals may degrade the polyurethane tread faster than normal. If your truck operates outdoors, consult the manufacturer for an outdoor-rated wheel alternative.
