Frequently Asked Questions
Q: What are the key specifications for the 00591-31861-81 load wheel?
A: The 00591-31861-81 is a polyurethane load wheel. It features sealed bearings, 95A Shore hardness, and is constructed from 305 compound polyurethane bonded to an iron core for superior durability and load resistance.
Q: Which electric lift truck brands are compatible with the 00591-31861-81?
A: This wheel is designed for Toyota electric lift truck applications. It is equivalent to Crown parts 310164, 4826270, and 4826279. Always verify your equipment model and mounting dimensions before ordering to ensure correct fitment.
Q: What part number does the 00591-31861-81 replace?
A: The 00591-31861-81 supersedes the earlier version 00591-31861-71. If your equipment currently uses the 00591-31861-71, you can upgrade to the 00591-31861-81, which features improved 305 compound polyurethane for extended durability and load capacity.
Q: Why is the 305 compound polyurethane specification important for this load wheel?
A: 305 compound polyurethane is a high-bond formulation that provides superior adhesion between the tire tread and iron core. This prevents tread separation during heavy loads and extends wheel life significantly. The 95A Shore hardness rating delivers excellent load resistance and maintains performance in demanding electric lift truck operations.
Q: Are there equivalent part numbers for the 00591-31861-81?
A: Yes. This wheel is equivalent to Crown parts 310164, 4826270, and 4826279. However, for Toyota equipment, ordering the exact part number 00591-31861-81 ensures you receive the correct specifications and factory-spec fitment for your application.
Q: What are the benefits of the sealed bearing design in electric lift truck applications?
A: Sealed bearings eliminate routine maintenance requirements for bearing lubrication and provide protection against warehouse contamination from dust and moisture. This design reduces equipment downtime and extends the overall wheel assembly service life in demanding electric lift truck environments.
