It prevents the flywheel from rotating independently of the crankshaft, which is necessary for consistent ignition timing. A sheared or damaged Woodruff key typically causes erratic ignition timing, hard starting, or complete failure to run, since the flywheel magnets no longer pass the ignition coil at the correct moment. Inspection of this key is recommended any time the flywheel is removed or when ignition timing problems are suspected.\u003c\/p\u003e\u003cp\u003eThis key is used in the flywheel and flywheel-ignition coil assemblies across a wide range of Wacker Neuson compact equipment.
