The crank pulley of your engine is designed to remain in place under the heavy loads exerted by your vehicle. In the centre of the crank pulley resides a bolt that threads into the end of the crankshaft. During use, the head of the bolt embeds in the face of the pulley wheel. Breaking the bond created between the bolt head and the pulley requires excessive force. Renting expensive electric or pneumatic impact guns will break the bond and your wallet. Breaking the bond manually with the proper crank bolt removal tool will remove the bolt without causing damage to the engine, crank pulley or motor mounts.
