Load Wheel Assembly for Allis Chalmers

Frequently Asked Questions

Q: What is the AC 74878390 load wheel assembly made from?
A: The AC 74878390 features Durarun 95A polyurethane construction. The 95A Shore durometer rating provides a balance of hardness and wear resistance for industrial material handling equipment and warehouse floor surfaces.

Q: What are the direct replacement part numbers for the AC 74878390?
A: The AC 74878390 has direct replacement part numbers: AC 74878390-A, AC74878390A, and 74878390A. These are equivalent part numbers used by different suppliers and equipment distributors. Verify part number format matches your equipment documentation before ordering.

Q: Why is 95A durometer important for a load wheel?
A: The 95A Shore durometer rating indicates the polyurethane hardness level. This durometer resists abrasion and flat-spotting while maintaining grip on warehouse floors, making it suitable for general material handling in ambient temperature conditions.

Q: What makes Durarun polyurethane different from standard polyurethane?
A: Durarun is a premium polyurethane compound engineered for extended wear life in demanding material handling applications. It resists cracking, flat spots, and material degradation better than standard polyurethane, providing superior durability for high-use equipment.

Q: Is the AC 74878390 suitable for wet or temperature-extreme storage?
A: The 95A polyurethane provides adequate grip in damp conditions. For cold storage below 0°F or high-traction wet floor applications, confirm the wheel compound is rated for those specific conditions. Contact technical support for cold-weather or high-traction wheel alternatives.

Q: What equipment types use load wheel assemblies like the AC 74878390?
A: Load wheel assemblies are used on electric lift trucks, electric pallet jacks, reach trucks, order pickers, and material handling equipment from multiple manufacturers. Confirm specifications match your specific equipment model before purchase.
