ABSTRACT:
An installation tool for use with a liner sleeve attachment, such as a nutplate assembly for mounting onto a substrate blind side as disclosed in U.S. Pat. No. 5,704,747. The installation tool includes retractable grip jaws for gripping and pulling a fixture pin protruding from the attachment, for initially advancing a tapered tool nose piece into deforming engagement with an attachment liner sleeve leading end to flare and/or expand the liner sleeve to lock the liner sleeve onto the substrate. Continued pulling action exerts a sufficient force to collapse a fixture pin head and thereby permit pull-removal of the fixture pin from the attachment. The nose piece is carried by a retractable inner housing normally retained in an advanced position for deforming the liner sleeve, and thereafter movable to a retracted position spaced from the liner sleeve to accommodate substantially unobstructed fixture pin separation from the attachment.
