Abstract

A clutch release mechanism includes an annular piston arranged to move an anti-friction bearing axially for operating a friction clutch between an engaged position and a disengaged position. The outer diametrical dimension of the anti-friction bearing is less than the internal profile dimension of the annular cylinder, whereby the bearing is movable into the space circumscribed by the cylinder when the piston is in its retracted position.
