ABSTRACT:
A cup seal installation device which has first and second handle parts each having an axially extending hole therethrough. Structure is provided for coupling the two handle parts together and for limiting the amount of reciprocal movement therebetween to first and second limits. A first outside diameter portion on the second part terminates in a first shoulder and a second outside diameter portion larger than the first outside diameter portion. An elongate guide member having a stem at one end thereof is removably received into the hole provided in the second handle part. The outer surface of the guide member and the outer surface of the first outside diameter portion on the second part are generally equal in diameter so that a smooth and unobstructed transition surface exists between the two surfaces. The end of the guide member remote from the stem has a guide surface thereon converging in a direction away from the stem so that the cup seal can be guided onto the guide surface with the initial converging wall of the lip on the seal being conformed to the converging wall of the guide surface. The seal can thereafter be slid along the length of the guide member to a position snugly encircling the first outside diameter portion to thereby ready the cup seal for installation.
