KEY - WOODRUFF (Komatsu KO011423)

A damaged woodruff key can cause the driven component to slip or fail entirely, leading to unexpected downtime. During inspection, a woodruff key may show signs of wear or shearing that compromise its ability to transmit torque. Keeping a woodruff key in sound condition helps maintain proper alignment between the shaft and the mating part. This aftermarket replacement part references the Komatsu catalog and carries the part number KO011423. The woodruff key type serves the general function of securing a rotating component to a shaft. A common failure consequence is that a worn key can allow the component to spin freely, resulting in loss of drive function. Verify the serial number or application, then call (562) 693-7748.
