Abstract: A device for plugging an axially-aligned bore in a shaft of a gas turbine engine comprises a plug. A sealing body of the plug is sealingly received in a bore of the shaft. Legs project from the sealing body and are displaceable between a normally contracted position in which the legs are radially inward relative to a periphery of the bore, and a deployed position in which the legs project radially outward and engage with shaft projections within the bore of the shaft. A wedge is operatively engaged to the plug for movement of the wedge relative to the plug. The wedge comprises a portion in operative contact with the legs of the plug unit to displace the legs between positions as a response to movement of the wedge. A gas turbine engine and a method for plugging a shaft are provided.
