Abstract
A method for installing or removing a bearing cup on a universal joint with the assistance of a tool is disclosed. The universal joint is of the type having a yoke including a pair of opposed arms which have inner surfaces facing each other. Each of the arms has an opening for receiving a bearing cup. The tool has a pair of contact surfaces which are spaced apart from one another by a distance which is approximately equal to the distance between the inner surfaces of the arms. To install the bearing cup, the tool is positioned between the arms so that the contact surfaces of the tool respectively abut the inner surfaces of the arms. The bearing cup is then pressed into the opening of one of the arms such that the tool prevents the pair of opposed arms from deflecting in a direction towards one another. Preferably, a cross having a pair of opposed trunnions is positioned between the arms so that the bearing cup is mounted on one of the trunnions when the bearing cup is pressed in the opening. A second bearing cup can then be installed in the opening of the other arm. To remove the bearing cups, the tool is positioned between the arms so that the contact surfaces of the tool respectively abut the inner surfaces of the arms. One of the bearing cups is then pressed through the opening of the respective arm, thereby causing movement of the cross which moves the other bearing cup out of the respective opening.
