Abstract

A supporting system (50) of a toothed wheel (12) onto a casing (CT) of an internal combustion engine (100). The system (50) comprises:
- a first bushing (53) supported by a wall (PT);
- a second bushing (54), adapted to support the toothed wheel (12), which crosses, in use, a through hole (51) made in said casing (CT); the second bushing (54) rests on said first bushing (53), and
- a screw (55) adapted to secure the second bushing (54) onto the first bushing (53), so as to form a seat (56) adapted to contain supporting and rolling means (57) of the toothed wheel (12).
