Flywheel Servicing INotel In order to produce the voltage necessary to run an
ignition system, the flywheel magnets must be of particular strengthWeak flywheel magnets can cause low ignition voltage, which could affect motor performanceWeak flywheel magnets can also cause low readings on ignition test equipment, such as the peak-reading voltmeter, which may cause unnecessary replacement of ignition componentsFlywheels rarely go bad and would only be replaced as last resort in solving an ignition problemRemoval
1To avoid accidental starting of engine while servicing, twist and remove all spark plug leads2Remove the remote starter or flywheel cover from the engine
3Remove the flywheel nutUse flywheel holding tool as drawn on Page 3-6 and three PI 309492 screws from ONIC Universal Puller Set, PIN 378103, or other suitable tool to hold the flywheelcare when threading screws into the flywheelThe screws can be threaded too far into the flywheel and can damage components mounted on the insideThread the screws carefully into the flywheel until resistance is feltThere should be enough thread engagement to loosen the flywheel nut or pull the flywheel4Apply OIVIC Moly Lube to threads of pressing screw and center hole of crankshaft5Assemble the following components from ONIC Universal Puller Set, PI 378103:
