ABSTRACT:
A bearing support member has two support arms extending in opposite directions along an axis. A bearing cup extends over each support arm and into a bore of the rocker arm and has a radially outwardly extending protrusion engageable with the rocker arm to limit axially outward movement of the bearing cups. A radially inwardly extending protrusion of the bearing cups abuts rolling members between the bearing support member and the bearing cups to limit axially outward movement of the rolling members. A stepped bearing sleeve and pedestal may be provided to limit axially inward movement of the rolling members. During assembly, components are inserted through an opening in the rocker arm intersecting the bore.
