Abstract
A rocker arm and method for manufacture is provided whereby the rocker arm is manufactured in two halves generally symmetric to a central plane. The mating surface of one or both rocker arm halves incorporate grooves which upon assembly provide passageways which may follow any desired pathway for lubricant and or afford a reduction in mass and/or an increase in structural stiffness. The two halves are preferably joined together by metallurgical brazing or by other chemical or mechanical means.
