ABSTRACT:
A puller device for disassembling parts having a plurality of arms provided with claws to grip the parts. The arms are rotatably connected to a hub. A pushing member extends through the hub and engages the parts. A slidable positioning member located on an exterior of the hub and extending away from the hub in a radial direction moves the arms between a free position and a gripping position. The hub and slidable positioning member each have a handle bar that can be gripped by a user. The arms move towards the free position when the handle bar of the slidable positioning member is urged towards the handle bar of the hub.
