Does anyone know if a Polaris 4010646 12 magnet flywheel will work on a TS1100LI. The casting number of the Polaris 4010168 is the same as the Tiger shark 3670-022. 4010646 is a direct replacement for the 4010168. Is the machining for the crank and keyway the same? I have had the magnets come off of two of the TS flywheels and don't want to put another one in.
