KEY - WOODRUFF (Mitsubishi MB2I7720)

A damaged woodruff key can cause the driven component to slip or fail entirely. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB2I7720. The woodruff key is a half-moon shaped mechanical fastener that prevents rotational movement between a shaft and a hub. A common failure consequence is that a worn or sheared key leads to sudden loss of torque transmission. Keeping a woodruff key in sound condition helps maintain secure coupling between rotating parts. The item ships at approximately 0.012 POUNDS.
