Clutch Quick Reference Definitions
Clutch: in a manual transmission, a device that allows the driver to engage and disengage the engine from the drive train
Clutch disc: the part of a clutch that receives the driving motion from the flywheel and pressure plate assembly and transmits that motion to the transmission input shaft
Clutch facing: the friction material on a clutch disc
Clutch fork: also known as the release fork. The device which moves the throwout (release) bearing, activating the pressure plate.
Clutch pressure plate: the part of the clutch assembly that is used to hold the driven disc against the flywheel. The pressure plate is composed of a cover and coil springs, driving disc and release levers, or a diaphragm spring
Clutch release bearing: a sealed ball or roller bearing unit that rides on a sleeve over the transmission input shaft, and acts on the pressure plate to disengage the clutch disc when the clutch release mechanism is applied. Also called a throw out bearing
Clutch throwout bearing: see 'clutch release bearing' above
Slave cylinder: a device that is connected to the release bearing in a hydraulic clutch system. When the clutch pedal is depressed, hydraulic fluid flows fro the master cylinder through the hydraulic fluid line to the slave cylinder. Pressure in the system causes the slave cylinder to act on the release bearing, disengaging the clutch.
