If you tried to heat the gear up on the cam all you did was heat the cam as well. Not good But anyway Heat The gear to about 180-200 in oil.You can do this in a oven Or on the stove in a OLD pot Use a temp sending unit if your going to do it on the stove. I have done this many times and was fine Let the cam sit in the freezer in the mean time. and It should press on with out Shaving the center of the Alum gear. and Will leave a NIce tight fit.
God doesn't like ugly.
