Rocker arm is the vital component of for Oldsmobile Cutlass engine's valvetrain and it plays the animated role in order to transfer the motion from the pushrod to the intake and exhaust valves. Standard rocker arms are fashioned from stamped steel or aluminum and translate up-and-down pushrod movement into the force needed open the valves. In high RPM operation, aluminum is used for the light weight benefits it offers as compared to cast iron, although cast iron or forged carbon steel is used in diesel applications where higher strength is required. Different types of Rocker Arm used in Oldsmobile Cutlass models are Metal on Metal Rocker Arm and Roller rocker arm have a needle bearing so it cause less friction. The rocker ratio which currently varies from 1.5:1 to 1.8:1 in some of the modern engines increases the direct lift by amplifying the movement of the camshaft. Modified fulcrum bearings are also used in high RPM engines to address the issue of stress and to extend the Rocker Arm system's reliability in Oldsmobile Cutlass cars.
