Procedure for tensioning the timing belt
Refit the pin Mot. 1054 and set the timing at its setting
point, (begin to press on the pin a half-tooth before
alignment of the mark on the camshaft pulley and
that made by the operator on the inner timing
housing, to prevent it falling into a crankshaft
balance hole).
Remove the pin Mot. 1054.
Apply pretension between the crankshaft timing
sprocket and the tensioner using the tool Mot. 1543
and the cover 1, adjusting the torque wrench to a
torque of 1.1 daNm.
Connect the sensor of Mot. 1505.
Check that the tension value is 85 ± 3Hz, readjust it
if necessary.
Tighten the tension wheel nut to a torque of 5 daNm.
NOTE: it is vital that you tighten the tensioner nut
to torque to avoid any loosening which may cause
damage to the engine.
WARNING: remove the washer numbered 4
included in the tool kit Mot 1543 before fitting the
crankshaft pulley.
