ABSTRACT:
A rocker arm assembly for mounting about a stud means. The rocker arm assembly generally comprises a rocker arm and a support member. The rocker arm has opposed first and second lateral ends and a central bore between the ends. The support member is positioned within the rocker arm central bore and mounted on the stud means. The rocker arm is configured to pivot about the support member. The support member has opposed lateral sides with a seal member extending along each lateral side. The seal members provide a seal between each lateral side of the support member and an internal surface of the central bore thereby providing more efficient oil lubrication to the ends of the rocker arm.
