CLUTCH

A. CLUCTH MASTER CYLINDER
The clutch master cylinder is mounted on the
firewall with its fork connected the Clutch pedal.
The master cylinder is a control device that
converts mechanical energy which comes by
pressing the clutch pedal into hydraulic pressure,
in order to actuate the concentric slave cylinder
which is located at the other end of the hydraulic
system. As the piston moves along the bore the
mechanical effort is converted into hydraulic
pressure. The pressure remains same in the
hydraulic line while force is magnified at slave
cylinder end because of increased piston area of
slave cylinder.
NOTE
The clutch master cylinder parts are not
serviceable and needs to be replaced completely
if found defective.
B. CONCENTRIC SLAVE CYLINDER
(CSC)
The clutch control mechanism is fully hydraulic.
There is no mechanical transfer (fork) from an
external slave cylinder. The concentric slave
cylinder (CSC) means that the slave cylinder is
integrated with the throw out bearing. The
concentric slave cylinder (CSC) is extremely
efficient and reliable and the throw out bearing is
accurately centered and secured to the clutch
housing using two screws. The bearings and
friction surfaces do not need to be lubricated. The
bearing on the concentric slave cylinder (CSC) is
self-centering against the clutch diaphragm
spring. The hydraulic line from the master cylinder
is connected to the concentric slave cylinder
(CSC) via an adapter and peak torque limiter.
Advantages of CSC:
Lighter pedal effort resulting in comfortable drive.
NOTE
When a self-adjusting clutch assembly is
replaced, the concentric slave cylinder (CSC) also
requires replacement.
Remove the protective cap just before installation.
The concentric slave cylinder parts are not
serviceable and needs to be replaced completely
if found defective.
C. PEAK TORQUE LIMITER
The peak torque limiter is the flow reducer located
between the clutch master cylinder and slave
cylinder in the hydraulic line.
The main function of the peak torque limiter is to
restrict flow of fluid below certain limit to avoid
sudden engagement of clutch.
The peak torque limiter does not come into picture
during normal driving.
NOTE
The PTL parts are not serviceable and needs to
be replaced completely if found defective.
D. HYDRAULIC ADAPTER
The hydraulic adapter connects the high pressure
line from CMC to CSC through a small opening in
the housing. The hydraulic adapter consists of a
bleeding valve which helps to bleed and drain the
clutch system. The bleeding valve is just an
ON/OFF valve which needs to be operated while
bleeding the system.
NOTE
The hydraulic adapter parts are not serviceable
and needs to be replaced completely if found
defective.
