. Operation
When the cover assembly and driven plate Is bolted
to the flywheel, the diaphragm spring comes under
Installation load and is deflected from Its free
shallow coned profile to an approximately flattened
condition.
This deflection, via the outer fulcrum ring, provides
the load on the pressure plate. Pressure on the
release plate will further deflect the diaphragm
spring, retracting the periphery due to the leverage
about the Inner fulcrum ring.
This action results In the diaphragm spring load
being relieved from the pressure plate, thus dis­
engaging the clutch.
The clutch Is operated hydraulically by a hydro­
static slave cylinder.
No adjustment Is necessary or provided for.
For details of the hydraulic system see previous
paragraphs In this section.

COVER ASSEMBLY
No servicing should be attempted on this assembly,
as the unit Is built and balanced during manufacture,
and must be replaced, If necessary, by a complete
assembly.
RELEASE BEARING
The release bearing assembly Is retained to the
clutch fork by two spring steel clips, which are
located by two flats on the reverse side of the fork.
(See Fig. 16).
To Remove
Rotate the clips over the end of the fork, and detach
the bearing.
To Refit
Place the retaining clips on the release bearing
trunnions.
(A).
Push the bearing Into place on the fork
(B),
with
the retaining clips between the bearing and the
fork.
Rotate each retaining clip Into position
(C)
until
It locates on the flat on the fork. (D). (See Fig. 16).
