ABSTRACT:
A tappet socket assembly for a rocker lever assembly or other lever assembly includes a retainer, a tappet socket, and a ball bearing. The rocker lever is adapted to be rocked about a pivot axis and includes a cylindrical opening or bore which partially receives the ball bearing. The retainer includes a cage provided by a plurality of legs and a cylindrical side wall insert. The side wall is secured within the cylindrical bore and press fitted therein by the ball bearing. The ball bearing exerts radially outward force on the retainer to secure the ball bearing and retainer to the rocker lever. The tappet socket includes a spherical concave recess that closely receives the ball bearing to provide a ball and socket joint and a flat engaging face for transferring the force of the rocker lever to a valve crosshead. The tappet socket is retained in the cage between the legs.
