Frequently Asked Questions
Q: What is the function of the 00591-37175-81 roll pin on a manual pallet jack?
A: The 00591-37175-81 is a Toyota OEM roll pin used to secure pivot and linkage connections on manual pallet jack mechanisms. It functions as a shear pin and retention fastener to keep mechanical assemblies aligned and functioning properly during pump and lift operations.
Q: How often should the 00591-37175-81 roll pin be replaced as maintenance?
A: Roll pins do not have a scheduled replacement interval and are replaced only when they fail or show damage. High-cycle applications with heavy daily use may experience pin wear or shear failures sooner than jacks in light-duty service. Inspect the pin during routine jack maintenance if accessible.
Q: What causes a roll pin to fail or break on a pallet jack?
A: Roll pin failures occur from fatigue cycling, overload stress beyond the jack rated capacity, inadequate lubrication at linkage points causing binding, environmental corrosion weakening the pin, or impact damage to the jack mechanism. Using the jack beyond its rated capacity accelerates pin failure.
Q: Can the 00591-37175-81 be used as a replacement for other Toyota roll pin part numbers?
A: Do not assume interchangeability between roll pins without verifying specifications. The 00591-37175-81 is designed for a specific mounting location and size. Using an incorrect pin diameter, length, or material may cause linkage misalignment, poor fit, or premature failure. Confirm the correct part number for your equipment before ordering.
