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.

II - REFITTING OPERATION
1 - Adjusting the timing
a
aSet the camshaft grooves horizontally and below the
centre line by turning the camshafts with the (Mot.
1496) if necessary.
aFit the (Mot. 1496) with the (Mot. 1750).aFit:
-the (Mot. 1496) fitted with the (Mot. 1750) on the
end of the camshaft,
-a lifting eye bolt to secure the (Mot. 1496).
aIf fitting a new camshaft dephaser, check the
dephaser locking mechanism (see 11A, Top and
front of engine, Camshaft dephaser: Removal -
Refitting, page 11A-135) .
aRefit the camshaft dephaser (see 11A, Top and
front of engine, Camshaft dephaser: Removal -
Refitting, page 11A-135) . Note:
If the stud loosens with the nut (see 11A, Top
and front of engine, Camshaft: Removal -
Refitting, page 11A-82) (Technical Note 3887A,

WARNING
Always degrease:
-the end of the crankshaft (timing end),
-the timing sprocket bore and bear ing faces,
-the crankshaft accessories pulley bearing
faces,
-the camshaft ends (timing end),
-the camshaft sprocket bores and bear ing faces.
This is to avoid timing slippage.
This slippage leads to engine damage.
