MODIFICATION TIMING
1 - PRESENTATION
1 - 1 - FOREWORD
Discontinuation of disengaging hubs on camshaft pulleys ; This modification gives rise to a modification in the method of timing belt removal/refitting .
1 - 2 - EARLIER ASSEMBLY
(1) Exhaust camshaft pinion disengaging type .
(2) Intake camshaft pinion disengaging type .
(3) Dynamic tensioner roller with excess tension mark .
(4) Fixed crankshaft pinion .
1 - 3 - LATER ASSEMBLY
(5) Exhaust camshaft pinion with damper .
(6) Fixed intake camshaft pinion .
(7) Dynamic tensioner roller with excess tension mark .
(8) Crankshaft flange .
(9) Crankshaft pinion of the disengaging type .
(10) Crankshaft key .
(11) Compartment .
NOTE : the timing pinion on the crankshaft has been made disengaging ; the extent of movement corresponds to the width (X) of the compartment (11) .
2 - REMOVAL - REFITTING
Timing belt .
2 - 1 - SPECIAL TOOLS
[1] Crankshaft setting rod (-).0189-B .
[2] Camshaft hubs setting rods (-).0189-A .
[3] Belt retaining clip (-).0189-K .
[4] Dynamic tensioner roller positioning rod (-).0189-J .
[5] Hub locking tool (-).0606.A1Y - (-).0606.A2 .
2 - 2 - REMOVAL
Remove :
WARNING : do not slacken the securing bolts (A) .
Peg :
Slacken the bolt (16) ( Fully) .
Remove the roller bracket (17) from the rib (B) of the cylinder block (to allow it greater movement) .
Remove the timing belt .
2 - 3 - REFITTING
Always renew ; The timing belt .
IMPERATIVE : check that the rollers (7) - (18) as well as the coolant pump (19) turn freely (no play or hard spots) ; also check that these rollers are not noisy and/or do not show traces of grease .
In the event of replacement ; Tightening torque(s) :
Engage belt on crankshaft pinion (9) respecting its fitting direction .
Immobilise the belt using the tool [3] .
Fit the timing belt, fully taut, in the following order :
2 - 4 - FITTING AND TENSIONING THE TIMING BELT
IMPERATIVE : operation(s) to be carried out : engine cold .
Position the roller bracket (17) back on rib (B) of the cylinder block .
Remove the tool [3] .
(C) Maximum position .
(D) Nominal tensioning position .
Using the hexagonal socket (E), turn the roller in the direction of the arrow until the pointer (22) is in position (C) to tension the belt to the maximum .
Fit the tool [4] .
Turn the roller in the direction opposite to that shown on the roller arrow by means of the torx recess (E) until cursor just makes contact with pin [4] .
IMPERATIVE : never turn the roller (7) by one full turn .
NOTE : this operation allows the pointer (22) to be located in the nominal position (D) .
Tighten screw (16), supporting roller with torx recess (E) : Tightening torque : 2 da.Nm .
Remove setting rods [1] - [2] and [4] .
Turn the crankshaft 10 turn(s) in the direction of running .
IMPERATIVE : never turn the crankshaft in the reverse direction .
IMPERATIVE : no pressure or outside force must be applied to the belt .
2 - 5 - CHECK
A : Timing belt tension .
Check position of tensioner index (22) .
If tensioner index is not in its adjustment position (D) : Restart tensioning operations for fitting the timing belt .
B : Position of the crankshaft .
Insert pin to locate inlet camshaft pulley ; Using the tool [2] .
Peg the crankshaft ; Using the tool [1] .
If it is possible to fit tool [1], continue replacement operations .
IMPERATIVE : if it is not possible to fit tool [1], reposition flange (8) .
2 - 6 - REPOSITIONING OF FLANGE
Immobilise crankshaft ; Using the tool [5] .
Loosen screw (15) to release pinion (9) from crankshaft .
Position flange (8) at timing point ; Using the tool [5] .
Fit the tool [1] .
Tighten screw (15) to 4 dan.m, then proceed with angular tightening of 53 ; Using a FACOM D.360 type tool .
Remove the tools [1] - [2] - [5] .
2 - 7 - REFITTING (CONTINUED)
