Clutch system operation

CLUTCH SYSTEM OPERATION

The diaphragm type clutch is operated via a hydraulic system.

When pressure is applied to the clutch pedal, fluid is pumped from the master cylinder to the slave cylinder causing the slave cylinder piston to apply pressure to the release lever. The release lever rotates the release fork and shaft.

The release fork changes rotary movement of the release lever into linear movement pushing the release bearing against the pressure plate diaphragm fingers, applying pressure to the drive plate springs and dis-engaging the clutch.

When pressure is released from the clutch pedal the master cylinder piston is returned by a spring which causes a pressure decrease. The drop in pressure allows the diaphragm fingers to push the release bearing back, decreasing the pressure on the drive plate springs and re-engaging the clutch.
