aparts always to be replaced: Timing belt tension-
ing rollerII - REFITTING OPERATION FOR PART
CONCERNED
aRefit a new timing tensioning roller.
aCheck that:
-the lug (20) of the tensioning roller is in place in the
groove (21) of the cylinder head,
-the high pressure pump mark (22) is one tooth to
the right from the vertical axis (23) ,
-the crankshaft is resting on the tool (Mot. 1489)
(the cotter (24) of the crankshaft timing sprocket
upwards).

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.

-the camshaft pulley timing pin (Mot. 1430).
aRotate the crankshaft twice clockwise (timing end)
before the camshaft pulley hole (28) is opposite the
cylinder head hole (29) .
aScrew tool (Mot. 1489) into the cylinder block.
aBring the crankshaft slowly and smoothly into con-
tact with the tool (Mot. 1489).
aSet the camshaft pulley using the (Mot. 1430).aIf the (Mot. 1430) does not fit in, loosen the camshaft
pulley wheel bolts by up to one turn.
aTurn the camshaft pulley hub using an offset span-
ner to set the camshaft pulley hub.
aDo not tighten the camshaft pulley wheel bolts.

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).
