5 MAINTENANCE, ADJUSTMENT AND TESTS
INSPECTION OF COMPONENTS
Check clutch disc hub splines for damage
and wear.
Check torsion damper mechanism springs for
distortion, damage etc. For this purpose, hold
drive shaft in vice. Insert clutch disc and slide
it as far back as possible. Rotate disc by
hand. Rattling noise and excessive play
indicates damaged torsional damping
mechanism and such disc must be replaced.
Check disc facing for wear, cracks, contact
pattern, burning marks and oil contamination.
Facings with any of the above defects or
worn out beyond permissible limits must be
replaced.
Check the correct position of clutch pedal
lever, which should be In-line with the brake
pedal lever, (During every service check the
clutch pedal lever is ln-line with brake pedal,
if not set in-line with the brake pedal lever).
CLUTCH SLIPPAGE TEST
Clutch slippage can be confirmed by any of
the following two methods:
Drive the car in 1st or 2nd gear at maximum
speed corresponding to that gear. Keeping
the accelerator pedal pressed with your right
foot, apply brake gradually with your left foot
If the engine stalls, it means that clutch does
not slip.
Drive loaded car in 3rd gear on level ground
and let the speed drop down to
approximately 15 kmph. Now press the
accelerator pedal fully. With slipping clutch,
the car speed will not pick up and also clutch
burning smell will be noticed. If this does not
occur and the car picks up speed, it indicates
that clutch does not slip.
