Rocker Lever Housing Assembly - General Information
The rocker lever housing assembly group consists of the rocker lever assembly, the step timing control (STC) oil
manifold connector, external oil manifold, internal oil tube, and the rocker housing cover. The rocker levers contain
replaceable bushings. The intake, the exhaust, and the injector rocker levers contain ball plugs to plug the oil
drilling holes in the levers. The rocker lever pad on the intake and the exhaust rocker levers is precision ground
and must not be repaired. Oil flows through the rocker lever shaft to the rocker levers. The levers are push rod
actuated and use an adjusting screw to control the clearance between the lever and the valve crosshead or injector
link.
