CLUTCH
It is a dry mono-disc clutch with hydraulic
command. The clutch mec hanism has a diaphragm
spring.
The clut ch d isc has an elastic hub.
Th e su pply of the hydraulic circuit is done
with liquid from the brake-liquid tank. The principle of this command is the same
as that of a brake command.
The cl utch pedal operates on the emitting
cy linder, which transmits the liquid under pres-
sure to a concentric hydraulic receiver, the mo-
bile part of which acts directly on the diaphragm
spring.
The hydrau lic receiver is fixed on the clutch crankcase through the agency of two screws.
