Frequently Asked Questions
Q: What are the exact dimensions and material of the TO 00591-73893-81 roll pin?
A: The TO 00591-73893-81 is a 302 series stainless steel slotted spring pin with a nominal 3/16 inch (0.187 inch) diameter and 1.375 inch length. Precision diameter is 0.1965 inch with a tolerance of ±0.0025 inch. Pin wall thickness is 0.04 inch with a passivated finish.
Q: What hole diameter must I drill to use the TO 00591-73893-81 roll pin?
A: The typical fitment hole diameter range for this pin is 0.187 inch up to 0.192 inch. The precision diameter of 0.1965 inch ensures the pin maintains spring tension within this range without binding or excessive play.
Q: Why is 302 series stainless steel used for this roll pin?
A: 302 series stainless steel provides corrosion resistance in electric lift truck hydraulic and mechanical assemblies. The passivated finish further enhances corrosion performance, making this pin suitable for wet storage and outdoor applications.
Q: Are there cross-reference or equivalent part numbers for the TO 00591-73893-81?
A: No cross-reference or superseded part numbers are available from primary sources for the TO 00591-73893-81. Use only the Toyota OEM part number to ensure correct specifications and fitment.
Q: What applications use this pin in electric lift truck hardware?
A: The TO 00591-73893-81 roll pin serves as a precision fastener in electric lift truck mechanical and hydraulic assemblies where vibration resistance and corrosion durability are required. Consult Toyota assembly documentation for specific component locations in your truck model.
Q: What is the difference between a slotted spring pin and a solid roll pin?
A: The TO 00591-73893-81 is a slotted spring pin, meaning it has a longitudinal slot allowing it to compress and retain spring tension when inserted into a hole. This design provides easier insertion and removal compared to solid roll pins while maintaining secure hold under vibration.
