aRefit the new timing belt:
-by lining up the crankshaft sprocket mark with the
mark on the inside of the timing belt,
-by lining up the camshaft sprocket mark with the
mark on the outside of the timing belt.
Procedure for tensioning timing belt
aRemove:
-the TDC setting pin,
-the tension wheel pin.aTurn the tensioning roller eccentric anti-clockwise,
using a 6 mm Allen key, to bring the adjustable in-
dex level with the fixed index.
aTorque tighten the tensioning roller nut (24 N.m).
aRotate the crankshaft through six revolutions in a
clockwise direction (timing end).
aSet the timing using the TDC setting pin (Mot. 1054).

aMake sure that the mark on the camshaft sprocket
and the mark on the crankshaft sprocket are aligned
with their fixed markings.
aRemove the TDC setting rod (Mot. 1054).aLoosen the tensioning roller nut up to one turn,
maintaining the position of the tensioning roller ec-
centric using a 6 mm Allen key.
aTurn the tensioning roller eccentric clockwise, using
a 6 mm Allen key, to bring the adjustable index to
the centre of the two fixed indexes.

Note:
Take care to properly tighten the timing belt
between the two camshaft sprockets.
Note:
Before torque tightening the fixed roller, always
adjust the junior torque wrench to 25 N.m
(tighten using the Mot. 1368 tool) to obtain a
tightening torque of 50 N.m on the fixed roller
bolt. The 25 N.m adjustment value is only valid
for a 300 mm long torque wrench (length mea-
sured between the square dr ive and the centre of
the handle). If the length of the torque wrench is
different, a new adjustment value m ust be used
(see Tightening torques: General information)
(01D, Mechanical introduction).
