ABSTRACT:
An assembly tool upon which a spring is secured for enabling the spring to be inserted within an orifice whose entrance diameter is smaller than the outside diameter of the spring is disclosed. The assembly tool includes (1) a mandrel consisting of a first and second section; (2) a securing device that locks one end portion of the spring to the mandrel as it is positioned upon the first section; and (3) a releasable locking device that is rotatably and slideably mounted upon the second section for securing the other end portion of the spring. Upon securing the ends of the spring in the securing device and the locking device, and rotating the locking device upon the second section of the mandrel, the outside diameter of the spring is reduced. The spring is then inserted within the orifice while it is secured to the mandrel, unlocked and thereby returned to its unwound position, and subsequently released from the mandrel.
