DESCRIPTION
A flywheel (part number 3979017) is a rotating mechanical device that stores energy in the form of rotational kinetic energy. It is typically made of heavy-duty cast iron or steel, and connects to the engine's crankshaft via a clutch or torque converter. The primary function of the flywheel is to maintain consistent rotational speed between the engine and transmission, especially during gear changes or when idling. It also helps reduce engine vibration and provides a smooth power delivery to the drivetrain. The flywheel's weight and size can affect an engine's performance, with heavier flywheels providing more inertia for smoother operation but slower acceleration, while lighter flywheels offer quicker response but may be less smooth at low RPMs.
