Red locktite melts at 'xx' temperature which can be obtained with either a propane torch or a heat gun. A hair dryer will not quite do it. Beware that grease smokes at that temperature, so do it outside. Red locktite is strong to something like 5,000 lbs force. The alternater on my Suzie 750 was glued on to the end of the crankshaft this way with no spline or lockring, this is why I know this. That engine developed 110 horsepower, can you?
