1. A method of assembling a rotary machine having a casing extending at least partially around a rotor comprising:
- providing a diaphragm patch ring;
assembling a diaphragm assembly by configuring a diaphragm bore portion to receive the diaphragm patch ring and forming a diaphragm patch member sub-assembly by coupling the diaphragm patch ring to the configured diaphragm bore portion; and
positioning the diaphragm assembly in a gap formed by the casing and the rotor.

Abstract
A method of assembling a rotary machine having a casing extending at least partially around a rotor is provided. The method includes providing a diaphragm patch ring. The method also includes assembling a diaphragm assembly by configuring a diaphragm bore portion to receive the diaphragm patch ring and forming a diaphragm patch member sub-assembly by coupling the diaphragm patch ring to the configured diaphragm bore portion. The method further includes positioning the diaphragm assembly in a gap formed by the casing and the rotor.
