Abstract
A valve train for use in an engine is provided. The valve train includes a rocker arm assembly having a valve side arm and a cam side arm. A valve is coupled to the engine and is in contact with the valve side arm. A pushrod is reciprocatable by a camshaft and is in contact with the cam side arm. An overload feature is located on at least one of the rocker arm assembly or the pushrod. The overload feature has a reduced cross-sectional area calibrated to activate at a predefined load.
