D. ALTERNATOR AND AC BELT
ALTERNATOR AND AC BELT REMOVAL
1. Remove the power steering belt (stretch belt) by
cutting the same.
NOTE
Do not reuse the power steering pump belt once re-
moved.
2. Remove the tensioner cap
(1)
and loosen the
tensioner bolt
(2).
3. Reduce the belt tension by rotating the tensioner
screw
(3)
in clockwise direction
(Tightening direc-
tion of a RH threaded screw)
and remove the
belt.
INSPECTION
Inspect the Alternator belt for wear, cracks and
signs of failures. Replace if necessary.
FITMENT
1. For fitment, first place the belt, and then tighten
the tensioner screw
(3)
by rotating it in the anti-
clockwise direction
(Loosening direction of a RH
threaded screw)
.
2. Tighten the tensioner bolt
(2)
to a torque of 4
Kgm and fit the cap.
3. Adjust the belt tension.
ALTERNATOR and AC BELT ADJUSTMENT
1. Remove the tensioner cap
(1)
and loosen the ten-
sioner bolt
(2).
2. Adjust the belt tension to as follows:
a. To reduce the tension rotate the tensioner
screw
(3)
in clockwise direction
(Tightening
direction of a RH threaded screw)
b. To increase the tension rotate the screw
(3)
in anti clockwise direction
(Loosening direc-
tion of a RH threaded screw)
.
Keep belt tension in given range .which is as follows.
For new Belt
Tension for new belt = 268 ± 10 Hz
NOTE
This value to be measured in the span between al-
ternator and AC compressor pulley (marked as “A” in
the above image)
Then run the engine for 15 mins. Now the belt has to
be retensioned to 244 ± 10 Hz.
For reusing same belt
In case of reusing the same belt, it should be ten-
sioned to
244 ± 10 Hz.
