ABSTRACT:
The system enables an increase in the guidance length of the outer pivot of the vane, so that the bushing can be extracted without needing to open the stator casing. It mainly includes a bushing placed inside a bossing of the stator, the length of which is greater than the length of the bossing projecting outwards from the bossing. Thus, the contact length of the outer pivot is prolonged. The bushing is terminated at its end by a gripping hook to enable extraction of the bushing by means of a claw. It is advantageously also provided with a positioning edge.
