Check and setting alternator standard belt

tension

5.9.1

Check

1. Check the belt condition A if worn out or deteriorated,

replace it.

2. 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 (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 (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 A must show a movement of less than 10 mm.

If not adjust it.

5.9.2

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 (tightening torque of 25 Nm) and C

(tightening torque of 69 Nm) in sequence with a torque

wrench E.

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

17mm (Fig. 5.10) (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 (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 A 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.
