Stegeman, G T

An integral rocker arm and hydraulic lash adjuster is described with load/motion control button assembly including a rocker arm having a cam actuated arm portion. An intermediate support portion with a cylindrical bore extends transversely therethrough. The valve actuator arm has a stepped bore therethrough and a slot means extending to the pivot axis and having a width so as to slidably receive the valve stem. The stepped bore defines a cylindrical enlarged lower wall defining a cavity, an adjuster guide wall, an enlarged intermediate wall and a further enlarged upper wall with a retainer groove therein and two abutment shoulders. A disc retainer is positioned in the intermediate wall. A split ring retainer is operatively positioned in the retainer groove to secure the disc retainer against axial movement in one direction. A hydraulic lash adjuster is operatively positioned within the follower body to abut at one end against the disc retainer.
