No dont heat it up, you will melt the elastomer used to bond it. Make sure everything is seated up square and straight and give it all you got. itll pop loose, and prolly be a fight the whole way off. You need to make sure the point of the puller shaft is turning straight in, If you are using a socket and the hole is too big then your force will be transferred into the screw digging into the socket instead of pulling the balancer. Make sure the hole isnt too big, and put some grease where the screw meets the socket you are using to help it turn. This should work for you. Dont sweat breaking that lil puller, The cheaper ones break all the time. Hope this helps.
