    Abstract: Roller forming portions of the VCT phaser to join the sprocket housing of the phaser to the end plates provides a reduction in oil leakage from the phaser as well as less distortion of the end plates of the phaser. Furthermore, by roller forming the sprocket housing of the VCT phaser to secure the end plates to the sprocket housing, the total number of parts needed is reduced, and the total number of holes needed to be drilled is reduced, reducing the overall cost of the phaser.
