ABSTRACT:
A combination tool for pulling gears, battery terminals, pilot bearings, wheel hubs, tie rods, steering wheel, harmonic balances and Pitman arms and for flaring pipes. The tool includes a yoke having four arms, each of which has an open-ended slot and a pin hole at the end of each arm. An arm pin in each arm provides a jaw member stop surface for large griping diameter pulling applications, and alternatively attaches the jaw member directly to the yoke arm for small gripping diameter applications. For other applications, a jaw member having an overhanging head is inserted into one or more yoke arm slots.
