<p>The cylindrical end part (11) of the bush (9) has at least one annular protrusion (17) provided around the outside of it in the circumferential direction, the external diameter of the protrusion being greater than the internal diameter of the top part of the hole (7) for the bush in the cylinder head base (5). The bush is pressed into this hole, causing elastic and/or plastic deformation of the protrusion as it is pressed inwards. The cylinder head (3) has a base containing at least one cylindrical hole for the bush. A top part of the hole extends between the top side of the base and a bottom part of the hole in communication with the bottom side of the base.</p> |
