Abstract
In an internal combustion engine having a rocker arm provided at one end with a roller contacting an exhaust valve stem for opening the valve, the rocker arm end portion is transversely slotted longitudinally normal to the axis of the valve stem to provide a longitudinally adjustable exhaust valve operating rocker arm. The transverse slot communicates with the transverse bore supporting the roller journalling bolt thus permitting adjusting movement of the roller longitudinally of the rocker arm and relative to the axis of the exhaust valve stem for the optimum friction reducing position of the roller relative to the valve stem.
