Frequently Asked Questions

Q: What is the purpose of the TO 00591-76102-81 cotter pin?
A: The TO 00591-76102-81 is a Toyota OEM cotter pin (split pin) manufactured from carbon steel. Cotter pins provide positive mechanical retention of critical fasteners and structural components in electric lift trucks, preventing accidental disassembly during equipment operation or maintenance.

Q: Which Toyota electric lift truck components use this cotter pin?
A: The TO 00591-76102-81 cotter pin is used in wheel axles, steering components, brake linkages, and other critical joints where fastener loss must be prevented. It is commonly paired with castle nuts or slotted fasteners to provide secondary fastening security in high-vibration material handling applications.

Q: What material is this cotter pin made from?
A: The TO 00591-76102-81 cotter pin is manufactured from carbon steel, which provides adequate strength and ductility for split-pin retention applications. Carbon steel is cost-effective and proven for material handling equipment, though zinc plating or protective finishes may be applied to resist corrosion in wet storage environments.

Q: How is a cotter pin installed and what size fastener does it secure?
A: Cotter pins are inserted through a hole in a castle nut or slotted fastener and then bent outward to prevent withdrawal. The TO 00591-76102-81 is sized to match specific fastener hole diameters on your equipment. Verify the fastener you are securing before ordering to ensure proper fit and retention strength.

Q: When should cotter pins be replaced?
A: Replace the TO 00591-76102-81 cotter pin whenever it shows signs of corrosion, breakage, or permanent deformation. After each major maintenance event involving fastener removal, install a new cotter pin. Do not reuse cotter pins if they have lost shape or material integrity, as this compromises retention security.

Q: Are there cross-reference part numbers for this cotter pin?
A: No known cross-reference or superseding part numbers exist for TO 00591-76102-81. This is a Toyota OEM part number only. If substitute cotter pins are required, match the pin diameter, length, and material specification to the original fastener.
