5.9 Check and setting alternator standard belt tension
Danger
•
For safety precautions see Chap. 3.
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 at 69 Nm [thread M10] - 40 Nm [thread M8]) 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 17 mm (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.
NOTE: Contact KOHLER authorised workshops for replacement.
