5.9 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
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.
3. 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
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
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.
