Frequently Asked Questions
Q: What is the SU S9151-XL-A equivalent to, and can I use those part numbers interchangeably?
A: The SU S9151-XL-A is equivalent to L509151, SU9151XL, SUS9151XL, and SU S9151-XL. Cross-reference your equipment documentation to confirm the original part number. While equivalent, always verify mounting dimensions and hub bore diameter before substitution. If you cannot confirm compatibility, contact your equipment OEM.
Q: What does XL3 high-bond polyurethane mean on the SU S9151-XL-A?
A: XL3 is a proprietary high-bond polyurethane compound designed for tough industrial applications. The high-bond formulation creates a stronger adhesion between the polyurethane tire and the steel core, resisting separation under heavy load and impact. This compound is engineered to withstand high cut and tear resistance, extending service life in demanding environments.
Q: Is the SU S9151-XL-A a wheel or a wheel assembly?
A: The SU S9151-XL-A is a complete load wheel assembly. It includes the high-impact steel core hub, XL3 polyurethane tire bonded to the core, and sealed bearings. It is ready to install as a direct replacement; no additional bearings or components are needed.
Q: Can the SU S9151-XL-A be repaired or re-tread?
A: No. The SU S9151-XL-A is a bonded assembly. The polyurethane tire cannot be separated from the steel hub and cannot be re-tread. Once the tire is worn or damaged, the entire wheel assembly must be replaced. Attempting to separate the tire will damage both components.
Q: What should I check before installing the SU S9151-XL-A on my lift truck?
A: Verify the axle diameter and bore depth match the hub specifications. Clean the axle of rust, dirt, and old grease. Check that the replacement assembly spins freely on the axle without binding. Secure the wheel with original fasteners and check for proper seating. If the wheel binds or will not slide onto the axle, do not force it; check axle alignment and hub bore compatibility.
Q: How often should the SU S9151-XL-A be inspected for maintenance?
A: Inspect the wheel assembly monthly during routine equipment maintenance. Look for visible cracks or separation of the polyurethane from the hub, sidewall damage, flat spots, or unusual noise during operation. Check bearing spin and feel for grinding or roughness. Replace the assembly immediately if damage is detected, as continued use can damage the lift truck axle.
