ABSTRACT:
A tool for removing a coupling cap when disconnecting the universal joint from a yoke, and installing a coupling cap when connecting a universal joint to a yoke. The tool includes a pair of anvils spaced apart for supporting the universal joint and yoke in a fixed vertical position. When the tool is used for disconnecting the U-joint, a rod is provided including a bottom end having an outer lip encircling the mouth of a bore extending inward therefrom. The lip impacts the portion of the yoke circumscribing the opening containing the cap in press fit association with the U-joint and the yoke in response to a downward force acting on the rod, to cause the cap to dislodge from the opening and move upward into the bore of the rod. When the tool is used for connecting the U-joint to the yoke, the rod is provided including a piston at the bottom end thereof. The piston pushes the cap into a press fit association in the space in the yoke opening between the side surface defining the opening and a projection of the U-joint, in response to a downward force acting on the rod. An alignment support urges the U-joint upward as the cap is being pushed downward.
