Abstract
Abstract An apparatus is described for pulling the pilot bearing from a flywheel or the like comprising a support member having a pair of spaced-apart bolt members threadably mounted therein. The support member has a central opening formed therein between the bolt members which receives a pair of pivotally mounted first and second jaw members having bearing engaging portions at one end thereof. The jaw members are extended through the central opening in the pilot bearing and then locked into position by means of a smaller bolt extending through the jaw members to limit the pivotal movement thereof. Threadable rotation of the first and second bolt members causes the jaw members to pull the pilot bearing from the flywheel.
