A rotor turning system for turning a rotor is provided. The system may include a rotary driver including a rotating drive shaft. A removable rotor grasping element is configured to frictionally grasp at least a portion of an exterior circumference of a portion of the rotor. A drive linkage couples the rotating drive shaft to the rotor grasping element to impart a torque to the rotor with the rotor grasping element to turn the rotor. A rotor grasping element is also provided for grasping a substantially smooth exterior surface of a rotor to allow for turning of the rotor. A related method is also provided.
