Checking the automatic tension wheel centre line
Before removing the accessories belt, check the
centreline (A) on the automatic tension wheel using
Mot. 1387.
Methods for using Mot. 1387
Loosen knurled bolt (1) so that the arms (2) and (3)
can slide against each other.
Position Mot. 1387 on the two mountings for the
tensioner component, then lock the arms (2) and (3)
by turning the knurled bolt (1).

METHOD FOR TIGHTENING THE CYLINDER HEAD
REMINDER: in order to tighten the bolts correctly, use
a syringe to remove any oil which may have entered
the cylinder head mounting bolt holes.
All the cylinder head bolts must always be changed
after removal. There is no cylinder head retightening
operation.
Preseating the gasket
Tighten all the bolts to 3 daN.m, then angle tighten to
100˚±4˚in the order shown below.
Wait 3 minutes settling time.
Tightening the cylinder head:
– cylinder head tightening is carried out in stages, and
the following procedure is applied successively to
bolts 1-2 then 3-4, 5-6, 7-8 and 9-10,
– slacken bolts 1-2 until they are completely free,
– tighten bolts 1-2 to 2.5 daN.m, then angle tighten to
213 ±7˚,
– repeat the slackening and tightening operations for
bolts 3-4, 5-6, 7-8 and 9-10.
There is no cylinder head retightening operation.

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.
