ABSTRACT:
A tool for removing hinge pins from aircraft. The tool head includes a lower member having an opening adapted for the receipt of a bent end of a hinge pin. An upper member is attached to the lower member so that it may pivot to cover and uncover the opening, thus securely locking the hinge pin in the tool head. The hinge pin rests in a groove in the lower member to properly position the pin in the tool head. The upper member is locked into position over the opening by tightening a wingnut on a threaded post against the upper member. A cutout section in the upper member provides clearance for the threaded post. The tool head may be mounted on the end of a slide hammer. The slide hammer shaft is threaded, allowing a drill chuck or other heads to be attached as the head of the slide hammer for hinge pins without bent ends.
