Abstract
A low cost and simple seal installation method provides for easy installation of bonded pistons and lip seals in an automatic transmission or other industrial machine. The installation method utilizes a flexible circular disc that can be inserted in a gap between the bore and the shaft and is pressed against the seal lip to flip the seal lip to its desired orientation while the disc is rolled around the circumference of the gap to orientate the entire seal in its proper position.
