Manual Transmission and Clutch





The primary function of the clutch system is to couple and decouple engine power to the transmission upon driver command.
- The clutch is a single-plate, dry friction clutch disc with a self-adjusting, diaphragm-style spring clutch plate. The clutch disc has a splined hub, which attaches the clutch disc to the input shaft.
- The clutch operating mechanism consists of a clutch slave cylinder with an integral release bearing.
- An input shaft which supports the end of the bearing. The bearing does not require lubrication unless the clutch system is repaired.
- The clutch system engages and disengages the manual transmission from the engine. The clutch system is disengaged when the clutch pedal is depressed and engaged when the clutch pedal is released. When the clutch pedal is depressed, it pushes the clutch master cylinder plunger, which hydraulically actuates the clutch slave cylinder. The clutch slave cylinder actuates the clutch pressure plate diaphragm spring, releasing pressure on the clutch disc. This release eliminates the engagement between the transmission and the engine.
