Cal-Van Tools ratcheting harmonic balancer pullers do the job without the hassle of trying to start bolts or the frustration of positioning multi-jointed puller legs. The pullers consist of a ratcheting yoke, a forcing screw, and a 3-piece harmonic jaw. There is no need to remove the radiator or other components with this compact design. The legs with puller feet quickly adjust and hold their position, providing a push, turn, and click design.
