C. FACTORS AFFECTING CLUTCH WEAR
The clutch is designed to give maximum life under
most severe conditions when handled carefully.
However, while in operation, clutch lining is
subjected to wear. Apart from this the extent of
wear also depends on following.
Automatic transmissions use pressure to apply
and release clutches, or essentially shift gears.
This pressure is affected by a number of
variables, but the baseline numbers are
determined in large part by the fluid and its
relative condition, which is affected by heat. Hot,
older fluid can decrease (or increase) the
pressures within the transmission beyond
engineered tolerances. When this happens
components begin to fail and soon the driver is left
with an expensive repair bill.
DRIVING
Following driving conditions will affect the
performance of the clutch.
D. REMOVAL OF CLUTCH FROM THE CAR:
1. Position and Lift the car using two post lift.
2. Disconnect electrical connections from AMT,
clutch position sensor.
3. Disconnect and remove transaxle along with
clutch housing from engine (for procedure refer
transaxle group).
4. Loosen the clutch lever interface.
5. Remove clutch release bearing with sleeve
6. Support clutch pressure plate and clutch disc
with mandrel & remove.
NOTE:
1.
It is recommended to replace a defective disc
having any of the above mentioned defects
with a new genuine clutch disc. We do not
recommend removal and replacing of clutch
facing.
2.
We do not recommend overhauling of the
clutch pressure plate assembly. However,
before re-fitment, the assembly should be
checked for specifications and should conform
to the data of clutch pressure plate assembly
given on page 3.
3.
Use correct clutch discs for the 1.22 NG NA
versions Identification.
4.
Use Disc and Pressure plate of the same
make. Ensure that the clutch facing material is
not contaminated with oil or grease as this
shall result in clutch slipping.
E. INSTALLATION OF CLUTCH ON THE CAR:
Carryout the clutch removal steps in appropriate
sequence for its fitment. However, following care
must be taken during installation.
Clean friction face of flywheel and check for
cracks, scoring, burn marks or unevenness. If
necessary, machine flywheel friction face just to
clear the defect.
Before fitment of clutch on the flywheel remove 3
protective clamps from pressure plate assembly.
For removal of 3 clamps, press Diaphragm fingers
of pressure plate assy. till the clamps becomes
loose & take it out.
Lightly apply Dow corning P40 grease on the disc
splines. Install disc and pressure plate assembly.
Press the aligning mandrel through the pressure
plate assembly and clutch disc and centralize
clutch disc on flywheel by locating the mandrel at
the flywheel end.
NOTE:
Do not mix clutch mounting bolts with other
fasteners. Do not use longer or shorter screws.
Longer screws may not tighten the clutch at all.
Shorter screws will not provide enough threads to
achieve desired tightening.
While tightening the clutch mounting screws
check aligning mandrel for continuous free
sliding to ensure concentric installation of
clutch disc which will avoid trouble during the
installation of the transaxle
