REFITTING
I - REFITTING PREPARATION OPERATION
aparts always to be replaced: Timing belt,
parts always to be replaced: Timing belt tension-
ing roller,
parts always to be replaced: Crankshaft acces-
sories pulley bolts.
II - REFITTING OPERATION FOR PART
CONCERNED
aRefit the new tensioning roller, making sure:
-that the cylinder head ribbing is between the two
tensioning roller lugs,
-that the tensioning roller pin is properly positioned,
-that the tensioning roller is positioned as in the dia-
gram.
aDo not remove the pin from the new tensioning roller

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).

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.
