Transmission / Transaxle
Clutch
General Description
Clutch ConstructionS7RS0B5301001
The clutch is a diaphragm spring clutch of a dry single disc type. The diaphragm spring is of a tapering-finger type,
which is a solid ring in the outer diameter part, with a series of tapered fingers pointing inward.
The disc, carrying four torsional coil springs, is positione d on the transaxle input shaft with an involute spline fit.
The clutch cover is secured to the flywheel, and carries the diaphragm spring in such a way that the peripheral edge
part of the spring pushes on the pressure plate against the flywheel (with the disc in between), when the clutch release
bearing is held back. This is the engaged condition of the clutch.
Depressing the clutch pedal c auses the release bearing to advance and pushes on the tips of the tapered fingers of
the diaphragm spring. When this happens, the diaphragm sp ring pulls the pressure plate away from the flywheel,
thereby interrupting the flow of drive from flywheel through clutch disc to transaxle input shaft. Clutch fluid is supplied
from brake fluid reservoir. Clutch fluid level can be checked by brake fluid level of brake fluid reservoir.
