ABSTRACT:
Manual rotation of a turbomachine rotor in order to bring the blades of the rotor one by one in front of an endoscope to check the blades is effected by a shaft which is rotatably connected to the rotor and which may be, for example, a shaft of the auxiliary equipment of the turbomachine, the shaft being manually rotatable by a driving shaft which is mounted in an opening in the casing housing the shaft and which is engageable with the shaft by self-disengaging coupling, a seal being provided between the driving shaft and the casing.
