CL 2778678

Frequently Asked Questions

Q: What equipment is the CL 2778678-A load wheel assembly designed for?
A: This Clark load wheel assembly is engineered for electric lift trucks and pallet jacks. For your specific equipment model and serial number, consult your equipment manual or contact Clark technical support to confirm fitment.

Q: What does 97A Shore hardness mean?
A: Shore A 97 indicates a very hard, rigid polyurethane formulation. This high durometer provides excellent wear resistance and minimal deflection under heavy loads, making it ideal for continuous warehouse and production floor use on concrete surfaces.

Q: What surface conditions is this XL poly wheel best suited for?
A: The CL 2778678-A performs optimally on hard, dry indoor surfaces such as concrete warehouse floors. It is not recommended for outdoor use, wet floors, or cold storage environments where grip and flexibility may be compromised.

Q: How long can I expect this wheel to last?
A: Wheel lifespan depends on load intensity, operating hours, floor surface condition, and maintenance. High-durometer polyurethane wheels typically provide 12 to 24 months of service in continuous warehouse operations. Regular inspection for wear and flat spots extends usable life.

Q: How should I store or maintain this load wheel?
A: Store wheels in a cool, dry environment away from direct sunlight and heat sources, which can degrade polyurethane. Inspect regularly for cracks, flat spots, and uneven wear. Clean wheels periodically to remove debris and contaminants that may affect rolling performance.

Q: Can this wheel be used in refrigerated or cold storage areas?
A: Standard 97A polyurethane becomes harder in cold temperatures (below 32°F / 0°C) and may lose grip on icy or wet floors. For cold storage applications, consult Clark about alternative formulations designed for low-temperature performance.
