Claim:
A method of repairing or of reworking a turbomachine disk including, on its rim, at least one external radial tab including an axial bore to accept an axial pin including a head and a shank with a threaded portion, the pin being slipped into the bore such that the head comes to press against one face of the tab through tightening of a nut on to the shank with a threaded portion against the opposite face of the tab, the pin forming a radial retaining system to keep a tab secured to a component attached to the rim, the method comprising: identifying a wearing zone on a radial surface of the tab; machining a spot face in the tab around the bore corresponding to the wearing zone so as to remove the wearing zone; enlarging the bore by machining to eliminate cracked material to make a new bore; and fitting a replacement pin including a flange pressing against a surface of the spot face, of a diameter greater than that of the head, the replacement pin including a shank with a threaded portion of a diameter corresponding to that of the new bore.
