wear.
ii. 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.

lever, which should be In-line with the brake
pedal lever, (During every service check the

1. CLUTCH SLIPPAGE TEST
Clutch slippage can be confirmed by any of
the following two methods:
i. 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.
ii.
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.
