Frequently Asked Questions

Q: What is the TO 00591-31017-81 hub assembly designed for?
A: This is a Toyota OEM hub assembly engineered specifically for polyurethane wheel applications on electric lift trucks. It provides the interface between the axle and poly wheel using sealed ball bearing fitment.

Q: What material and finish does the TO 00591-31017-81 hub have?
A: This hub is precision-machined carbon steel with zinc plating. The zinc plating provides corrosion resistance in damp warehouse and cold storage environments typical of electric lift truck operations.

Q: Is the TO 00591-31017-81 hub compatible with aftermarket wheels?
A: This hub is designed for sealed ball bearing fitment and interference fit installation. It is compatible exclusively with original Toyota electric pallet jack poly wheel assemblies. Verify wheel bore diameter and bearing specification match before ordering.

Q: What equipment models accept the TO 00591-31017-81 hub assembly?
A: This hub is engineered for designated Toyota electric lift truck models using poly wheel assemblies. Check your equipment documentation or part manual to confirm compatibility with your specific model series.

Q: Are there equivalent part numbers for the TO 00591-31017-81?
A: No documented cross-reference or superseded part numbers are available. Use the exact OEM part number TO 00591-31017-81 for correct fitment.

Q: How does the sealed ball bearing design affect maintenance?
A: Sealed bearings reduce friction and heat generation in the hub assembly. They require no periodic lubrication and provide longer operational life compared to open bearing designs, typically 4 to 6 years in standard duty.
