Before working on any
part
in the engine
compartment, turn off the engine and let
it cool down sufficiently. If work has to be
done with the engine running, exercise
extreme caution to prevent neckties,
jewelry or long hair from getting caught
In
the
V-belt.
Incomplete or improper servicing may
cause problems in the operation of the
car. If in doubt about any servicing, have
it done by your Authorized VW Dealer or
any other properly equipped and quali-
fied workshop.
Adjusting or replacing
V-belt
Turn the engine off!
To adjust
Ihe
belt, remove the rear half of
the pulley on the alternator. When
loosening and tightening the nut, place
a screwdriver through the cut-out in the
front half of pulley and support the
screwdriver as shown
in
the picture.
The belt tension is adjusted by varying
the number of washers between the
pul-
ley
halves
Taking washers out increases
Ihe
tension, putting them in decreases it.
Extra washers are stored on the outside
of the pulley half.
The V-belt must not be too tight or too
loose when you are making the following
belt tension check: Depress one side of
the belt at the center between the two
pulleys. The tension
is
correct if the
bell
can be depressed between 043
(
7
/IB)
In.
or 11 mm and 0.55
(
9
/
16
)
in. or 14 mm
al
a pressure of 16.5
lbs.
or 7.5 kg (a firm
press with your thumb).
This
It only a temporary adjustment.
Have final adjustment made by your
dealer.
A new belt may stretch slightly at
first.
To
compensate for
this,
the belt should be
a-to
loosen
b-to tighten
tightened slightly more when first in-
stalled,
The deflection should be be-
tween 0.35
("hi)
in.
or 9 mm and 0.43
P/ts)
in.
or 11 mm at the same pressure.
The correct belt tension will then be
reached after about 30 minutes of oper-
ation.
The heavy-duty V-belt has a very low
stretch factor. When properly installed,
the belt tension will remain fairly
con-
stant. Volkswagen-recommended V-
bells
have a relatively long service life,
however,
it is good planning to always
carry a spare belt in your car.

Ihe
belt,
