Clutch: Description and Operation
CLUTCHDESCRIPTION
Manual transaxle equipped models utilize a modular clutch assembly. The clutch system consists of a modular clutch assembly (Fig. 1), a sleeve type release bearing, a self adjusting clutch cable, and a clutch pedal that is part of a brake/clutch pedal bracket assembly.
The modular clutch assembly consists of a single, dry-type clutch disc, a diaphragm style clutch cover, and an integrated flywheel. The clutch cover is riveted to the flywheel, containing the clutch disc within. The modular clutch can only be serviced as an assembly.
OPERATION
MECHANICAL
The clutch assembly is designed to transmit power from the engine to the manual transaxle. This is accomplished by the friction and clamping force generated when the spring loaded pressure plate locks the clutch disc to the flywheel (Fig. 2). The clutch disc, which is splined to the transaxle input shaft, transmits power until the center of the diaphragm spring is depressed, and the clamp force is removed from the disc.
CLUTCH RELEASE SYSTEM
A sleeve-type release bearing is used to engage and disengage the clutch cover pressure plate. The release bearing is operated by a pivoting release lever in the clutch housing (Fig. 4). The lever pivots on a ball stud within the housing. The release lever is actuated by a self-adjusting clutch cable (Fig. 3).
The clutch cable has a unique self-adjuster mechanism (Fig. 3) built into the cable which compensates for clutch disc wear. The preload spring maintains tension on the cable. This tension keeps the clutch release bearing (Fig. 4) continuously loaded against the fingers of the clutch cover assembly The cable requires no maintenance or lubrication.
