KEY - WOODRUFF (Yale YT237966)

YT237966: A damaged Woodruff key can cause a shaft-mounted component to slip or fail under load. During inspection, a Woodruff key may show signs of wear or shearing that compromise torque transmission. The key's plain mechanical function is to fit into a keyseat and prevent relative rotation between a shaft and a hub. A concrete generic failure consequence is that a broken key can lead to sudden loss of drive or timing, potentially halting operation. Keeping a Woodruff key in sound condition helps maintain positive engagement between rotating parts. This aftermarket replacement part references the Yale catalog and carries the part number YT237966. Verify the serial number or application, then call (562) 693-7748.
