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.
