ABSTRACT:
A mounting assembly for a universal joint that includes a yoke with wings between which a driving shaft is provided. The wings have respective holes. A bolt having a head and a stem is transversely to the wings. A sleeve receives the stem of the bolt so that, in an assembled position, the sleeve exerts a pressure on a surface of the driving shaft preventing its axial movement, wherein the stem has at least a first, threaded end portion, a second, non-threaded adjacent portion, and a third portion. The diameter of the second portion is slightly larger than an inner diameter of the sleeve. The third portion has a diameter slightly larger than the second portion. When the bolt is inserted into the sleeve, the sleeve expands resulting in an increase of its outer dimensions against the surface of the driving shaft blocking it axially in position as it is pressed against the yoke. The third portion of the bolt is received in one of the holes, thereby seating the bolt with respect to the yoke.
