Clutch: Description and Operation

CLUTCH DESCRIPTION CLUTCH COMPONENTS





Models equipped with a 2.4L Gas engine utilize a modular clutch assembly (F. 1). The modular clutch consists of a single, dry-type clutch disc, a diaphragm style clutch cover, and an integrated flywheel. The clutch cover (pressure plate) is riveted to the flywheel, and therefore can only be serviced as an assembly.






Models equipped with the 2.5L Turbo Diesel engine utilize a conventional clutch system (F. 2). This system consists of a flywheel, clutch disc, and clutch cover (pressure plate), which is fastened to the flywheel, capturing the clutch disc within. Each component is individually serviceable, however it is highly recommended that the clutch cover and disc be replaced as a set.













RELEASE SYSTEM
All models utilize a hydraulic clutch release system, consisting of a clutch master cylinder attached to the clutch pedal (F. 3), and a slave cylinder fastened to the transaxle, which operates the clutch release lever (F. 4).

When the driver depresses the clutch pedal, the master cylinder pushrod travels through the cylinder bore, displacing fluid through the master cylinder plumbing. This fluid displacement forces the slave cylinder piston to travel, forcing the clutch release bearing into the clutch diaphragm spring via the release lever and leverage (F. 5). This releases the clamping force on the clutch disc, allowing the engine crankshaft to rotate independently from the transaxle input shaft.
