General description (Opel Omega A)

All models with manual transmission have a single-plate clutch with a diaphragm spring. The clutch housing is bolted to the rear surface of the flywheel.

The friction disc is located between the flywheel and the pressure plate and is placed on the grooves on the input shaft of the gearbox. When the clutch is engaged, the diaphragm spring presses the pressure plate against the friction disc, which in turn is pressed against the flywheel. Rotation is transmitted from the flywheel through the friction disc to the input shaft of the gearbox. When the clutch is disengaged, the pressure plate moves away from the friction disc and the drive to the gearbox is disconnected.

The clutch is controlled by a pedal mounted under the dash and a cable connected to the clutch release lever on the gearbox. Pressing the pedal causes the release lever to move the release bearing against the fingers of the diaphragm spring in the clutch housing. The spring is clamped between two rings that act as supports. As the center of the spring moves inward, the outer part moves the pressure plate outward and disengages the clutch.

When the friction disc pads wear out, the pedal gradually rises relative to the base position and therefore it is necessary to periodically adjust the height and stroke of the pedal.
