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 removed.
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 direction 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
tensioner 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
direction 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 alternator and AC compressor
pulley (marked as “A” in the above image)
Then run the engine for 15 mins. Now the belt has
to be re-tensioned to 244 ± 10 Hz.
For reusing same belt
In case of reusing the same belt, it should be
tensioned to
244 ± 10 Hz.
