Nozzle Mounting and Sealing Assembly and Method of Mounting and Sealing a Nozzle Assembly

A nozzle assembly (10) includes a nozzle having a trailing edge of an outer band (14) and an anti-rotation pin slot (40). Also included is a retaining ring (50) extending circumferentially about the outer surface of the outer band, wherein the retaining ring includes an anti-rotation pin (52) and an anti-rotation pin hole (53), wherein the anti-rotation pin is configured to fittingly reside in an axial orientation within the anti-rotation pin slot and the anti-rotation pin hole. Further included is a seal plate (60) seated on the outer surface of the outer band (14) and configured to retain the anti-rotation pin. Yet further included is a washer (90) disposed within a bored portion (80) of the seal plate (60), wherein the bored portion (80) is aligned with an aperture within the retaining ring, wherein a mechanical fastener extends into the retaining ring (50) through the bored portion (80) to operably couple the seal plate to the retaining ring.
