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.
aTorque tighten the tensioning roller nut (24 N.m),
maintaining the position of the eccentric using a 6
mm Allen key.

-remove the tensioning roller and the timing belt,
-insert the tensioning roller pin,
-repeat the timing belt refitting method from the be-
ginning, step by step.
