WARNING
In order to eliminate any risk of damaging the
rotary switch under the steering wheel, observe
the recommendations below:
!Before the steering column and the steering
rack are uncoupled, the steering wheel MUST
be immobilised with the wheels straight for the
duration of the operation using a "steering
wheel locking tool".
!If there is any doubt regarding the correct
alignment of the rotary switch, the steering
wheel must be removed so that the alignment
procedure described in the "AIRBAG" section
can be applied.
REMINDER: in this case, only qualified
personnel who have received training may carry
out the operation.

those of the camshaft, injection pump and crankshaft
sprockets.
Bring the tension wheel into contact with the belt by
tightening a bolt to the inner timing cover.
Remove pin Mot. 1054.Apply a pretensioning torque using Mot. 1543 (fitted
with cover N˚ 3) by using a torque wrench adjusted to
a torque of 1.1 daN.m on the edge of the belt to be
measured.

Fit the reading head of Mot. 1505 and carry out the
measurement, then adjust the tension using the bolt
in contact with the belt until pretension value
T1 = 68 ± 3 Hertz is reached.
Tighten the tensioner.
Turn the crankshaft four times and reposition the
timing at top dead centre using the pin.
Remove pin Mot. 1054.
Apply a pretensioning torque using Mot. 1543 (fitted
with cover N˚ 3) by using a torque wrench adjusted to
a torque of 1.1 daN.m on the edge of the belt to be
measured.
Fit the reading head of Mot. 1505 and carry out the
measurement, then adjust the tension using the bolt
in contact with the belt until pretension value
T2 = 61 ± 5 Hertz is reached.
Tighten the tension wheel nut to a torque of 5 daN.m.
NOTE: it is vital that you tighten the tension wheel
nut to torque to avoid any slackening which may
cause damage to the engine.
Never refit a belt once removed, but replace it.
Replace the crankshaft pulley bolt and tighten it to a
torque of 2 daN.m plus an angle of 115˚ ± 15˚.
See section 07 "Accessories belt tension" for the
tension value for fitting the power assisted steering
belt.The belts on vehicles fitted with air conditioning are
tensioned by bringing the automatic tensioner plate to
a stop at bolt (B), without forcing it, using a 9.35 mm
square.
