The clutch consists of a clutch disc, a clutch drive with a pressure plate, and a release mechanism. The release mechanism is mechanical and is controlled by a self-adjusting cable. The clutch disc is installed between the flywheel and the pressure plate and moves along the splines of the primary shaft of the gearbox.
The clutch master assembly is bolted to the flywheel. Torque during engine operation is transmitted from the crankshaft through the flywheel and clutch disc, which is clamped between the flywheel and the pressure plate, to the primary shaft of the gearbox. The clutch disc has a torsional vibration damper and asbestos-free linings.
To disengage the engine from the gearbox, it is necessary to move the pressure plate away from the clutch disc. Peugeot cars use two different clutch release mechanisms. The first is the conventional type, where the release bearing is mounted on the primary shaft of the gearbox. The second type is where the release bearing is an integral part of the leading clutch assembly.
A unified clutch housing is supplied as a spare part, allowing both solutions to be used. In the first case, (with release lever) it is mandatory to use a ball joint corresponding to the disk diameter. The characteristic values of the clutch adjustment dimensions have remained unchanged.
When the clutch pedal is pressed, the cable moves and rotates the clutch release fork by the upper end of the fork. The fork, turning, compresses the pressure springs and moves the pressure plate away from the clutch disc.
Since January 1988, the clutch release lever has been replaced by a special axle passing through the clutch housing and controlled directly by a cable (without intermediate lever).
As the clutch disc friction linings wear, the clutch pedal height increases, so the clutch cable needs to be adjusted to ensure proper clutch action. However, since mid-1994, an automatic adjustment clutch cable has been installed (it can be installed on earlier models as well). The automatic regulator is included in the central part of the clutch cable.
