This is one of those tools you want to have if you are doing anything involving the timing belt or crankcase. Trying other methods will end in injury or damaging of engine components. An impact wrench should never be used on engine components such as the crankcase. Using this removal tool in combination with a breaker bar will allow someone to easily and correctly remove a crankcase. The tool feels very solid and did not flex or seem to on the verge or breaking at any point during use.
