Clutch Controls
DESCRIPTION
AND OPERATION
Because of this separate chamber, the braking
system remains operational if a leak occurs in the
hydraulic clutch system.
Function
Pressure is created in the master cylinder when
the clutch pedal is operated.
The hydraulic fluid in the master cylinder is put
under pressure and fed through the pressure pipe
to the slave cylinder.
The displaced hydraulic fluid moves the piston in
the slave cylinder and this in turn slides the release
bearing axially.
The release bearing pushes the bearing inner ring
against the tongues of the diaphragm spring.
The spring induced grip between the clutch disc
and the flywheel is broken.
When the clutch pedal is released the diaphragm
spring presses the piston in the slave cylinder back
to its starting position. The spring induced grip
between the clutch disc and the flywheel is created
again.
A spring in the slave cylinder ensures preload on
the release bearing.
The release bearing is always touching the
pressure plate because of this preload. The extra
travel caused by clutch lining wear is compensated
for by the preload.
There is a choke assembly in the slave cylinder
which helps to increase smoothness when pulling
away.
Because of the choke assembly, the pressure drop
of the fluid leaving the slave cylinder and returning
to the reservoir is delayed.
Because of this, the clutch closing time is delayed
when the clutch pedal is released suddenly, and
a soft and comfortable clutch engagement is
achieved.
Choking does not occur during clutch
disengagement.
A CAUTI0N:Vehicles with an automated shift
manual (ASM) transmission have
a slave
cylinder without
a choke assembly. The
slave cylinders must not be exchanged for
one another.
N0TE:The clutch pedal travel cannot be adjusted.
The release bearing is an interference fit in the
slave cylinder and cannot be renewed separately.

Differential assembly
Item Description

1 3 1 Differential assembly I
4 Sender wheel - Vehicle Speed Sensor
I I (VSS)
The differential assembly is built into the
transmission housing.
The drive torque is transmitted to the differential
by the crown wheel which is bolted to it. The differential
assembly contains differential
pinion gears mounted on a spindle and the axle
halfshaft pinion gears which connect to the front
wheel axle halfshafts through helical gearing.
The axle halfshaft pinion gears can revolve around
the differential pinion gears when the road wheel
speeds are different
(e.g when cornering).
On vehicles without Anti-lock Brake System (ABS)
a VSS detects the speed of the differential
assembly at the VSS sender wheel.
On vehicles with ABS the VSS sender wheel is
also installed. The VSS is however not installed in
this case. A plug with an O-ring closes the
corresponding bore instead.
