Frequently Asked Questions
Q: What is the purpose of the TO 00591-58477-81 caster axle and nut?
A: The TO 00591-58477-81 is a caster axle pin assembly with retaining nut for Toyota electric lift trucks. This component connects the wheel hub to the caster frame and allows the wheel to rotate freely. The nut secures the axle assembly to prevent lateral movement or separation.
Q: Is the TO 00591-58477-81 sold as a complete axle assembly with nut included?
A: Yes. The TO 00591-58477-81 includes the axle pin and the retaining nut as a single service kit. When replacing this part, you receive both components needed for a complete axle reassembly. No additional fasteners are required.
Q: How long does a caster axle assembly typically last on Toyota electric lift trucks?
A: Caster axle lifespan depends on load rating, floor conditions, and maintenance frequency. Under normal warehouse operations, expect 2 to 5 years of service. Frequent operation on rough floors or consistent overload conditions reduces lifespan. Worn axles produce grinding noise or wheel wobble and should be replaced promptly.
Q: Are there equivalent part numbers for the TO 00591-58477-81?
A: No cross-reference or equivalent part numbers are published for TO 00591-58477-81. Order using the exact OEM part number. Mismatched axle assemblies can cause improper wheel spacing, binding, or unsafe caster operation on your lift truck.
Q: What is the material composition of the TO 00591-58477-81 axle and nut?
A: The TO 00591-58477-81 axle is hardened steel with a zinc or nickel plated finish for corrosion resistance. The retaining nut is steel with matching plating. This construction provides durability in humid warehouse environments and wet storage areas where corrosion is a concern.
