<p>The casing has a fin (15) whose end is in the form of tongues (15B, 15B', 15B'') adapted to be integrated with inner and outer shells (13, 14) arranged opposite to the fin end based on a dovetail type fastener. The tongue cooperates with an axial maintenance part i.e. complementary groove (16) formed in the shells arranged opposite to the end. The maintenance part is connected on the tongue forming the fin end and screwed with the shells. The maintenance part has a positioning unit arranged to cooperate with a complementary unit arranged in projections (13B, 14B) of the shells. An independent claim is also included for a method for disassembling a fin of an intermediate casing.</p> |
