G.M. Harmonic Damper Holding Tool

• This harmonic damper pulley holding tool was developed to aid in the removal and installation of the crank bolt
• The bolts holding these pulleys are extremely tight and without the #64700, removal is extremely difficult at best
• In replacing the center bolt after installation of the pulley, factory specifications require up to 240 pounds of torque to seat the pulley properly
• These tools allow the factory torque to be attained
