Cam follower and method for manufacturing such a cam follower

A cam follower, comprising:

• a tappet which includes two flanges provided with opposite holes centered on a transverse axis;
• a pin extending along the transverse axis between two opposite ends received in the opposite holes;
• and
• a roller movable in rotation relative to the pin around the transverse axis and adapted to roll on a cam;
• wherein each of the opposite holes is provided with:
• an open portion for mounting the pin by translation in a first direction perpendicular to the transverse axis,
• a cylindrical portion for supporting the pin along the first direction and
• a plane portion for retaining the pin along the transverse axis during transport and mounting of the cam follower, wherein the pin is partly movable in the opposite holes,
• the flanges further comprising deformed portions devoid of contact with the ends of the pin.

• the method comprising a mounting step, the mounting step comprising a step of:
• wherein the machining step is accomplished following the mounting step
• mounting the pin into the opposite holes by translation in the first direction, without deforming the flanges
• plastically deforming the flanges to prevent dismounting of the pin by translation in a second direction opposite the first direction, wherein the plastically deforming step is accomplished following the mounting step, plastically deforming the flanges to prevent dismounting of the pin by translation in a second direction opposite the first direction, wherein the deformed portions of the flange are devoid of contact with the ends of the pin, such that the pin is partly movable in the opposite holes.
