There is an arrow painted on the back of the belt
showing the direction of rotation and two marks
for the setting.
Line up the marks (N) on the belt with those on
the sprockets (L) and the housings (M).
Respect the direction of mounting of the belt and
begin to position it on the crankshaft sprocket.
Fit the sensor of
Mot. 1273.

Turn the knurled wheel of the sensor until it re-
leases (three "clicks").
Tension the belt using tool
Mot. 1135-01 until
the display of the
Mot. 1273 shows the re-
commended fitting value
.
Belt tension (in SEEM units)
Fitting value: 30 U.S.
Lock the tension wheel, carry out a check and ad-
just the value.
Rotate the crankshaft at least
three turns.
Check that the tension value is within the fitting
tension tolerance (
±10 %), and if not readjust it.
NOTE : Never refit a belt which has been remo-
ved.
Tighten nut (O) of the tension wheel to 5 daN.m.
It is essential to tighten the tension wheel nut to
a tor
que value of 5 daN.m to prevent any risk of
working loose which might damage the engine.
WARNING: Certain camshaft s
prockets have five
marks, but onl
y the rectangular mark on the face
of a tooth shows the TDC. The other marks are
used for ad
justing the valve rockers.
