Abstract:
1. A rocker arm system for internal combustion engines wherein rocker arm components and geometry are dimensionally located on and from reference axis and planes comprising: a first reference axis being longitudinally concentric with the valve center; a first reference plane collinear through the first reference axis, being the plane where rocker arm pivot geometry and pivot center is indicated; a second reference plane being a normal plane to the first reference axis and the first reference plane, dimensionally located from the valve tip end; a second reference axis being a rocker arm pivot axis and lying on the normal plane coincident with a rocker arm pivot center located on the first reference plane and consistent dimensionally from the valve tip end; a third reference surface plane, a surface being parallel to the second reference normal plane, wherein rocker arm components, adjustment shims and mounting surfaces are dimensionally defined; said third reference surface plane being applicable to establish defining positions and orientations for said components.
