ABSTRACT:
A method and apparatus is provided for field balancing an assembly including a power turbine. The method includes coupling the power turbine to a load, identifying a first balancing plane that is aft of the power turbine, and identifying a second balancing plane that is forward of the power turbine. A balancing correction is determined at each of the first and second balancing planes. A balance weight is mounted at the first balancing plane based on the balancing correction determined for the first balancing plane, and a balance weight is mounted at the second balancing plane based on the balancing correction determined for the second balancing plane, wherein each balance weight at the second balancing plane is coupled to a respective bolt head without removing the bolt.
