ABSTRACT:
A cast rocker arm for operating the valve train of internal combustion engines characterized by its light weight and use of anti-friction bearings to reduce frictional forces and increase engine mileage. The cast construction produces a light weight, and includes a box or channel cross-sectional configuration to achieve high strength with a minimum of material.
