Abstract: Valvetrain of an internal combustion engine, including a rocker support, a fulcrum, and a rocker. The rocker support is mounted to a cylinder head and fixed relative thereto. The rocker is positioned about the rocker support and partially in an axial aligning groove of the rocker support. The fulcrum is sandwiched between the rocker support and the rocker. The rocker oscillates about the fulcrum as forces are received and applied to a first and a second end of the rocker.
