V-belt
Maintenance and inspection 11
Inspection of the V-belt
Check the V-belt for wear and tear, cracks and fissures
and ravels. In all of these cases the V-belt must be
replaced. Only check the V-belt when the engine is not
running.
Verifying the tension of the V-belt
The tension of the V-belt is correct if it can be moved
by no more than 12 mm, using thumb and forefinger
and a force of about 10 kg. If the travel of the belt is
greater, the tension must be adjusted.
Tensioning the V-belt
In order to tension the V-belt, the bolts of the support
and both bolts of the alternator must be loosened.
Tension the belt by pushing the alternator outward.
Thereafter, first tighten the upper bolt of the alterna-
tor and thereafter the support and the lower bolt of
the alternator.
