Abstract
An actuating piston, and a piston assembly and a disconnect system including the actuating piston are provided. The actuating piston includes an annular backing plate having an axial projection on a first side between an inner radius and an outer radius and an annular piston having a recess between an inner radius and an outer radius. The annular piston is disposed on the annular backing plate so that the axial projection is received in the recess. The actuating piston is selected from a set of actuating pistons, each having a different height based on at least one of the wall thickness of the annular piston being varied or a height of the axial projection being varied, and one of the actuating pistons with a desired height is selected based on an actual height of the friction device.
