Power off the robot and disconnect the cable to the Franka Control Box.

Gently move the robot arm in the direction of the green arrow while supporting the weight of the arm.

Notice the gap on the fairings (blue circle) once the arm has been moved.

The screw boss blocks (red circle) are present on both sides of the robot. Tap on them lightly to remove.

After removing the screw boss blocks, the actuator assembly and everything downstream of the broken joint should be free to rotate along the purple arrows.

The actuator is still locked and does not contribute to the rotation.
