A propane torch will not be so hot. Alcohol or acetone will cut grease rapidly.

Ed are you suggesting I use propane or its not hot enough? I heat the brackets up , then apply the kroil and it does get sucked up in the threads. But i cant get the screw to move at all. Theirs just no way to smack on it hard enough to make it move without braking to adjuster wheel. Did some looking around today looking for machinist today.
