WOODRUFF KEY (Bobcat BC64655-4)

BC64655-4: A worn woodruff key can cause a drive component to slip or fail entirely. This aftermarket replacement part references the Bobcat catalog number BC64655-4. The woodruff key is a small, half-moon shaped fastener that locks a rotating part to a shaft. Its plain mechanical function is to transmit torque between the shaft and the hub. A common failure consequence is that a sheared key will stop power transfer, leaving the attached component non-functional. During a repair, a technician may find the key has deformed under load. Verify the serial number or application, then call (562) 693-7748. This item ships at approximately 0.02 pounds.
