The mounting and tightening the belts is the same sequence in reverse.

First mount the lower timing belt (2) (Fig.8.10.1). Pull the tensioner forward to screw the two bolts (1)
(Fig.8.10.3) and one screw (5) (Fig.8.10.1). Fasten lightly bolts (1) and (2)(Fig.8.10.3) and tighten the belt by
screwing the screw (5)(Fig.8.10.1) or (Fig.8.10.4).
The he belt tension can be tested with a Frequency tension Tester
Optibelt 3 TT (Fig.8.10.4) or manually by pushing with a force of 16
kg or 35.3 lbs in point A , the deflection of the belt must be 3.44 mm
or ±0,135Inch (Fig.8.10.5). It is recommended that the tension of the
belt be measured with a Frequency tension Tester Optibelt 3 TT .
The tension of the belt must be (220-230) 1/s. When the tightening is
done, screw in bolts (1) and (2) (Fig.8.10.3) and recheck the tension.
It is possible to tension the belt by using the pre-installed supports
(5) (6) as references, provided that have not been moved from their
factory position.
