A tool for installing and aligning a bearing cap in a universal joint so as to position an end surface of the bearing cap a predetermined distance above the outer surface of the arm of the end yoke is generally cup-shaped, including a generally flat, circular end portion having a hollow cylindrical skirt portion. The skirt portion defines an inner diameter which is slightly larger than the outer diameter of the bearing cap. The skirt portion also defines an axial length which is equal to the desired predetermined distance. A cut-out may be formed in a portion of the tool to receive a spring tab or other axial retaining structure for the bearing cap. Also, one or more apertures may be formed in the end portion of the tool to receive anti-rotation protrusions formed on the end surface of the bearing cap. The universal joint is assembled by initially disposing the tool over the end surface of the bearing cap such that the inner surface of the end portion abuts the outer end surface of the bearing cap. A press is then used to exert a force against the outer surface of the end portion of the tool, urging it and the bearing cap axially inwardly such that the bearing cap is moved over the end of the trunnion until the open end of the skirt portion of the tool engages the outer surface of the yoke arm. The axial length from the inner surface of the end portion of the tool to the end of the skirt portion is sized to be equal to the desired axial distance by which the end surface of the bearing cap extends beyond the outer surface of the yoke arm. The tool provides a quick and easy method for installing the bearing cap on the trunnion and simultaneously aligning such bearings cap at a predetermined location relative to the outer surface of the yoke arm. |
