This tool uses a long nut / stud to connect to the crankshaft end and a thick tube that allows you to pull the crankshaft through the main bearing without damage. By only pushing on the inner bearing race no damage to bearings will occur . Assembly is the same only you don't heat the crankcase. You pull the crankshaft through the bearing and this slides the two crankcases together.
