A method of balancing a ram air turbine that has a turbine shaft with a turbine shaft axis, a rotor attached to the shaft, rotor blades attached to the rotor that move between a fine pitch and coarse pitch position, a spring-loaded governor for controlling the position of the blades that has its springing retained by a stationary outer spring seat and a movable inner yoke plate that slides on the turbine shaft and whose position determines blade pitch, comprises the steps of: pulling the yoke plate toward the spring seat to displace the yoke plate toward the spring seat sufficiently to cause the rotor blades to assume a desired degree of pitch; spinning the turbine shaft at a desired rotational speed; balancing the rotor to minimize vibration of the rotor with the desired rotor blade pitch and turbine shaft speed; and releasing the pull of the yoke plate toward the spring seat.
