• This unique tool has been developed to aid in the removal and installation of the crank bolt on most Honda and Acura engines. It has been re-engineered to work on 2004 and later new style SUV’s with 50 mm damper pulley as well as all the models the 60100 serviced. In operation with the use of a 1/2" breaker bar or ratchet, this tool holds the harmonic damper pulley from rotating when removing and setting the final torque specification on the pulley bolt. There is a hole in the center of the tool to allow the use of a socket and extension to break loose or tighten the pulley bolt.
