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.

aFit the timing belt, starting with the crankshaft
sprocket, aligning the marks on the belt with those
on the crankshaft sprockets, the camshaft and the
high-pressure pump. There should be 19 tooth spac-
es between the sprocket marks and 51 tooth spaces
between the crankshaft sprockets and the high pres-
sure pump.
aBring the tensioning roller adjustable index (26) op-
posite the lug (27) using a 6 mm Allen key, turning
anti-clockwise.
aTighten the tensioning roller bolt.

1 - First position
aLoosen the tensioning roller bolt by up to one turn,
holding it with a 6 mm Allen key.
aGradually align the adjustable index (31) in the mid-
dle of the timing window (32) , turning the key anti-
clockwise.2 - Second position
aLoosen the tensioning roller bolt by up to one turn,
holding it with a 6 mm Allen key.
aGradually align the adjustable index (33) in the mid-
dle of the timing window (34) , turning the key clock-
wise.
aTorque tighten the tensioning roller bolt (27 N.m).
aTorque tighten the camshaft pulley wheel bolts
(14 N.m).

3 - Timing belt tension
aPosition the adjustable index (25) opposite the mark
(26) , by turning the eccentric (27) clockwise using a
6 mm Allen key.
aTorque tighten the tensioning roller nut(7 N.m).aRefit:
-the lower timing cover (28) ,
-the crankshaft accessories pulley (29) (see 11A,
Top and front of engine, Crankshaft accesso-
ries pulley: Removal - Refitting, page 11A-20) .

aCheck through the lower timing cover window that
the adjustable index (31) is opposite the notch (32) ,
if this is not the case:
-loosen the timing tensioning roller nut by up to one
turn while holding the eccentric with a 6 mm Allen
key,
-gradually move the adjustable index marker (31)
opposite the mark (32) turning the eccentric cam
(33) clockwise.
aTorque tighten the timing tension wheel nut (27
N.m).5 - Checking the timing
aEnsure that the index and the notch on the timing
tensioning roller are in the correct position before
checking the timing.
aScrew in the TDC setting pin (Mot. 1489).
aBring the crankshaft slowly and smoothly to rest
against the TDC setting pin (Mot. 1489).
aPosition (without forcing) the camshaft setting tool
(Mot. 1496) fitted with the (Mot. 1750) (the camshaft
end grooves must be horizontal and offset towards
the bottom).
aRemove:
-the timing tool (Mot. 1496) fitted with the (Mot.
1750),
-the TDC setting pin (Mot. 1489).
