Abstract: A spring installation tool for article loading machines is provided to facilitate the application of a biasing spring to sets of guide fingers. Fundamentally, the invention includes an elongated frame member having a tubular portion at a first end thereof for receiving the biasing spring. A rod is provided having a ring at one end which encompasses the tubular portion while being maintained in spring-biased engagement at an opposite end thereof with a second end of the frame member. The rod is operative for reciprocating movement with respect to the frame member to effectuate forcing of the biasing spring from the tubular portion. In use, the tubular portion, bearing a biasing spring, is placed over the end section of a set of guide fingers and the rod is reciprocated to force the spring from the tubular portion into securing and biasing engagement with the fingers.
