Re: Flywheel Key
Do you have the magneto cam off? This is a little metal collar that goes over the crankshaft and activates the points. It pulls straight off.<br /><br />If it's jammed on by the sheared key, you may have to remove the magneto plate to pry it. That's fairly easy to do, just remove the linkage and 4 phillips screws. Then it will lift off and out of the way.<br /><br />40-45ft/lbs sounds correct. Verify your torque wrench is accurate, and clean the end of the crankshaft and the taper in the flyweel to remove any burrs, etc. Then lap the flywheel to the crankshaft employing vavle grinding (lapping) compound for a perfect fit. Then clean the taper & crankshaft up, leaving no trace of grease or oil.<br /><br />The key is never supposed to keep the flywheel from rotating - it's purpose is simply to index it for installation.
