Abstract: An improved construction of a pulley puller and in particular a pulley puller wherein two pull pawls and a base are provided with two flanges and two grooves respectively to provide stability at the point where they meet supportively, tractive members formed in one piece are disposed between the pull pawls and the base, a fixed ring is casted integrally with the base, the base also having a central hole having therein an internal thread, a hexagonal flange end is formed integrally at one end of the central hole and a supported screw rod is fitted through the central hole so that when operating the pulley puller it will remain stable and the pull pawls will not slip or otherwise slide out of the contact surface between the pull pawls and the base.
