All the models with manual transaxle have a single dry plate, diaphragm spring type clutch, with a splined hub, to enable the clutch disc to slide on the splines of the input shaft of the transaxle. The pressure plate is in direct contact with the clutch, by the diaphragm spring pressure in the pressure plate. The clutch release system is hydraulically controlled and consists of the clutch pedal, the
Clutch Master Cylinder, the clutch release cylinder and the hydraulic line between the two cylinders. Upon the release of the clutch by pressing the clutch pedal, the master cylinder causes movement to be searched to the release cylinder causing the clutch release lever to be activated. As the lever pivot involves the release bearing, the fingers of the diaphragm spring of the pressure plate assembly, and the clutch plate is released. Clutch terms may differ with the slave cylinder being known as the clutch release cylinder, the driven plate being known as the clutch plate or disc, the pressure plate assembly being known as the clutch cover and the
Clutch Release Bearing being known as the throw-out bearing. Besides changing visibly damaged parts, the initial test to identify the clutch system failure involves paying attention to the spin down time in engine at idle speed with transaxle in Neutral, disengaging the clutch, and shifting into Reverse without any grinding sound, which would be an indication of the problem with the pressure plate or the clutch disc. To confirm full release of the clutch, the engine is to be running with the parking brake engaged and the clutch pedal approximately 1.5 inches above the floor and switch between 1 st and Reverse gears; the rough movement of the gears indicates a component malfunction. A physical examination of the clutch pedal pivot to be stuck or excessively worn should also be carried out as well as leaks in the hydraulic lines at the master and release cylinders, and bleeding the system (where applicable).
