The Cal-Van Tools Low Profile Ratcheting Pulley Puller, No. 38000, is designed to remove harmonic balancers without the hassle of trying to start bolts or the frustration of positioning multi-jointed puller legs. It features a push-turn click design and has three ratcheting legs with puller feet to eliminate the need for bolts. There's no need to remove the radiator or other components with this compact design, the company says. The legs quickly adjust and hold their position. Ideal for Ford 3.0 Coyote, GM 5.3L, 5.7(LS1), 6.0(LS2), 6.2(LS3), and 7.0L, and most three and six spoke harmonic balancers/pulleys applications.
