Maintenance and inspection

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.

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.

Inspection of the V-belt

Verifying the tension of the V-belt

Tensioning the V-belt

In order to tension the V-belt both bolts of the alternator
must be loosened. Tension the belt by pushing the alter-
nator outward. Thereafter, first tighten the upper bolt of
the alternator and thereafter the support and the lower
bolt of the alternator.
