The new one (on the left) and the old one (on the right).

Out with the old (on the left) in with the new (on the right).

In a depression (6) in the end wall (3) of the gearbox housing on the outside of the housing, a hydraulic release cylinder (40) is arranged with a release bearing (46).

A clutch assembly (10) having a clutch (10), release bearing (16), and input shaft inertia brake assembly (36) is disclosed.

An electric clutch actuator shifts the release bearing (16) axially along an input shaft (18) of a transmission system to either engage the clutch (10) or engage the input shaft inertia brake (30).

The clutch abutment is incorporated in the free end of the piston (1) in the form of a back-up ring (20) maintained by a ball-bearing fitting.

The invention is characterised in that the disengagement bearing is arranged substantially within the inner ring of the cover bearing at least during part of an actuating stroke of the annular piston.

So you put up with him, because it's better to have him there, than not have him ;-)
