4.9 Check and setting alternator standard belt tension

4.9.1 Check
1 - Check the belt condition A if worn out or deteriorated,
replace it.
3 - Check that at point p the tension value is between 70 and
75 Hz for V-belt of 9 mm and 80 and 85 Hz for V-belt of 17
mm (Fig. 4.8) (H).
Using the tool F (DENSO BTG-2) shown in the picture
(or a similar one) it is possible to check the corresponding
value in Newton, (which should be) included between 200
and 230 N for V-belt of 9 mm and 350 and 450 N for V-belt
of 17 mm (Fig. 4.8) (H).
Should the correct tool not be available, the belt tension
can be checked by applying a force in the direction of
arrow G of approx' 10kg on the point p. When correctly
tensioned the belt must show a movement of less than 10
mm.
If not adjus it.
4.9.2 Adjustment
1 - Loosen the fastening bolts B and C.
2 - Pull the alternator outwards (in direction of the arrow D), to
tension the belt.
3 - Tension the belt tightening the bolts B and C.
4 - Tighten bolts B and C in sequence with a torque wrench E
(tightening torque of 40 Nm).
5 - Check that at point p the tension value is between 70 and
75 Hz for V-belt of 9 mm and 80 and 85 Hz for V-belt of 17
mm (Fig. 4.8) (H).

can be checked by applying a force in the direction of
arrow G of approx' 10kg on the point p. When correctly
tensioned the belt must show a movement of less than 10
mm.
Let the engine run for some minutes, then let it cool down
at ambient temperature and repeat the operations 2, 3,
4 and 5 in case the belt tension results out of the above
mentioned values.
