ABSTRACT:
A system for actuating a clutch by axial movement of an actuating member which is rotatable about a clutch axis with the axial movement for actuating occurring via engagement of the actuating member with a clutch release bearing, the system including a fluid actuated clutch release bearing assembly actuable along a central axis which is generally in line with the clutch axis, and with the clutch release bearing assembly including alignment means separate from the clutch release bearing for moving the axis of rotation of the clutch release bearing substantially into alignment with the clutch axis and with the clutch release bearing assembly including a housing member having an annular, axially extending cylinder portion having a cylinder cavity adapted to receive a piston for reciprocation therein, and with the system including a seal located in the cylinder cavity and operative with the piston to hold the inner end of the piston in a radially spaced relationship with the confronting walls of the cylinder cavity.
