摘要： The invention relates to a method of repairing or of reworking a turbomachine disk comprising, on it's rim, at least one external radial tab with an axial bore to accept an axial pin comprising a head and a shank with a threaded portion, the pin being slipped into the bore in such a way that the head comes to press against one face of the tab through the tightening of a nut on to the shank with threaded portion against the opposite face of the tab, said pin forming a retaining means to keep a tab secured to a component attached to the rim.It is characterized in that a spot face (123B; 223B; 323B) is machined in the tab around the bore (123A; 223A; 323A) corresponding to the wearing zone, and a replacement pin (100) comprising a flange (111A) pressing against the surface of said spot face, of a diameter greater than that of the head (111) is fitted.
