Method of assembling a planet carrier

A method of assembling a planet carrier comprising:

• separately producing a cage and a cage carrier, wherein the cage comprises a plurality of posts and the cage carrier comprises a plurality of fingers;
• providing a bulge at least one of the following elements:
• a through opening of an internal saddle and of an external saddle of at least one of the posts of the cage, a through opening of at least one of the fingers of the cage carrier, at least one bearing seat of the cage, and at least one antifriction bearing seat of a shaft attached to the cage carrier,
• assembling the cage and the cage carrier by placing each of the fingers of the cage carrier between an internal saddle and an external saddle of a corresponding post of the cage;
• positioning the cage with respect to the cage carrier and attaching together the cage and the cage carrier so as to obtain a single-piece assembly;
• determining a position of at least one reference axis linked to at least one of the cage, the cage carrier and the shaft;
• and
• while taking into account the position the of at least one reference axis, machining all or part of the bulge so as to ensure an alignment between at least one of the through opening of the internal saddle and of the external saddle of each of the posts with the through opening of the corresponding finger, and the at least one bearing seat of the cage with the at least one of the antifriction bearing seats.
