Flywheel 545221701

This flywheel is an authentic manufacturer replacement part for use with lawn and outdoor equipment. The flywheel is a heavy, circular disc that has magnets that create an electric charge sent to the spark plug to create the spark that ignites the fuel and air mixture in the engine. It is attached to the engine crankshaft by a key known as a shear pin or flywheel key. This assembly is a critical component in the starting and running of your power equipment. Over time, the magnets on the flywheel will wear down, and the flywheel may chip and crack. A faulty flywheel will result in a loss of power, excessive shaking during use, and difficulty starting the equipment. Remove the flywheel using a flywheel puller. Position the new flywheel on the crankshaft and secure it with the retaining nut and flywheel key. This flywheel is sold as an individual replacement part.
