The Duralast Ratcheting Harmonic Balancer Puller, No. 81-057, provides technicians with a faster way to remove the balancer on some of the most common Ford, Dodge, and GM engines. Using this puller is as simple as backing off the center screw, sliding the puller into place, and tightening the screw again until the balancer is freed. With its compact design, this 5-ton puller eliminates the need to remove the radiator or other components that restrict access. It can switch between three-legged and two-legged configurations depending on the task and can remove dampeners and pulleys as well.
