aPosition:
-the RENAULT badge (18) etched on the exhaust
camshaft pulley stem vertically and pointing up-
wards,
-the camshaft dephaser pulley mark (19) vertically
and facing upwards.
aMake a mark (20) using a indelible pencil between

2 - Refitting the timing belt
aFit a new tensioning roller by positioning the tension-
ing roller lug in the rib (22) .
aScrew on the tensioning roller nut without tightening
it.aRefit:
-the cottered crankshaft timing sprocket (23) ,
-a new timing belt,
-a new fixed roller (24) .
aPosition the (Mot. 1490-01) on the camshaft sprock-
ets.
aTorque tighten the fixed roller bolt (50 N.m) using
the tool (Mot. 1368), a junior torque wrench and a 15
mm socket.
aRemove the tool (Mot. 1490-01).

Note:
Take care to properly tighten the timing belt
between the two camshaft sprockets.
Note:
Before torque tightening the fixed roller, always
adjust the junior torque wrench to 25 N.m
(tighten using the Mot. 1368 tool) to obtain a
tightening torque of 50 N.m on the fixed roller
bolt. The 25 N.m adjustment value is only valid
for a 300 mm long torque wrench (length mea-
sured between the square dr ive and the centre of
the handle). If the length of the torque wrench is
different, a new adjustment value m ust be used
(see Tightening torques: General information)
(01D, Mechanical introduction).

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,

4 - Checking the tension
aRotate the crankshaft twice in a clockwise direction,
on the timing end, before aligning the marks (on the
camshaft dephaser) already made by the operator.
aScrew in the TDC setting pin (Mot. 1489).
aMove the crankshaft slowly and smoothly to rest on

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).
