Frequently Asked Questions
Q: What are the specifications of the 00591-31874-81 load wheel?
A: The 00591-31874-81 is a Toyota OEM polyurethane load wheel assembly with the following dimensions: 4.00 inch outside diameter, 2.50 inch tread width, and 2.047 inch bore diameter. Material is Millennium Standard polyurethane compound with 92A durometer hardness. The wheel features a sealed bearing system.
Q: What equipment does the 00591-31874-81 fit?
A: The 00591-31874-81 is designed for Toyota electric pallet jacks and electric forklifts requiring a 4.00 inch OD load wheel with 2.047 inch bore. It also cross-references to Crown part number 083179, making it compatible with Crown equipment using that part specification.
Q: What does 92A durometer hardness mean for the 00591-31874-81?
A: The 92A Shore A hardness rating indicates a medium-firm polyurethane compound suitable for general facility floors. This hardness provides adequate load capacity and traction on concrete, tile, and standard warehouse flooring. For cold storage or wet floors, higher hardness compounds may be required.
Q: Does the 00591-31874-81 wheel have a sealed bearing system?
A: Yes, the 00591-31874-81 features a sealed bearing system that provides protection against moisture and contaminants. This sealed design reduces maintenance requirements and extends wheel lifespan compared to open bearing designs, provided the seal remains intact.
Q: Can the 00591-31874-81 be used as a replacement for other wheel part numbers?
A: The 00591-31874-81 is equivalent to Crown part 083179 for compatible applications. Before substituting wheels from different manufacturers or part numbers, confirm that the 4.00 inch OD, 2.50 inch tread width, and 2.047 inch bore match your equipment specifications exactly.
Q: How durable is the Millennium Standard compound in the 00591-31874-81?
A: The Millennium Standard polyurethane compound in the 00591-31874-81 provides heavy-duty durability for industrial pallet jack and forklift service. Standard compound typically delivers 2000-4000 operating hours of service life depending on load weight, floor conditions, and usage intensity before wear replacement becomes necessary.
