Frequently Asked Questions
Q: What are the dimensions and material of the 00591-75861-81 roll pin?
A: The 00591-75861-81 is a Toyota OEM slotted spring pin (roll pin) manufactured from high carbon spring steel. The pin is 1/8 inch in diameter and 1-1/4 inch in length. The slotted design allows radial compression during press-fit installation and springs outward to lock in the hole.
Q: What Toyota forklift models are compatible with the 00591-75861-81 roll pin?
A: The 00591-75861-81 is compatible with Toyota forklift models 7FBCU25, 7FBCU32, 7FB25, 7FB30, 8FBCU50, 7FBSU25, and related manual pallet jack assemblies. Verify your specific equipment model and the application location before ordering to ensure correct fitment.
Q: What is the difference between a roll pin and a standard straight pin?
A: The 00591-75861-81 roll pin has a slot running its length that allows compression during press-fit installation into a drilled hole. Once inserted, the spring tension in the high carbon steel forces the pin to expand radially against the hole walls, creating a permanent press-fit connection. This design provides secure retention without threading or fasteners.
Q: Can the 00591-75861-81 roll pin be reused after removal?
A: The 00591-75861-81 is a press-fit spring pin designed for single-use applications. After removal, the high carbon spring steel may be permanently deformed and lose its spring tension, reducing the ability to maintain a secure fit. Replace with a new OEM part for reliable retention.
Q: What is the expected lifespan of the 00591-75861-81 roll pin in service?
A: High carbon spring steel roll pins like the 00591-75861-81 provide long-term retention in normal operating conditions. Failure occurs primarily from fatigue stress cycles under shock loads, corrosion in wet environments, or gradual loss of spring tension over many years. Inspect for visible cracks, rust, or looseness if equipment experiences frequent vibration or impact.
