For emergency operation of an automatic friction clutch (3) of a truck which is operated during normal running by an electronic controller (9) via an electric motor driven actuator (11) and a hydraulic system (19, 21, 23), it is proposed that the clutch be controlled manually via a compressed air actuator (29), in particular via a compressed air servo actuator, by means of a changeover valve (39) which connects the compressed air actuator (29) alternately to a compressed air source (37) or via a flow throttle (41) to the atmosphere.

Arrangement for operating a friction clutch of a motor vehicle, in

The invention relates to a method of assembling a friction clutch, wherein the clutch housing is centered with a cylindrical portion on a cylindrical guide of the flywheel and the axially correct position is found by axial application and measurement of the initial tension of the clutch main spring and the clutch housing and flywheel are rigidly connected to one another in this state.
