Setting the timing.
Removing.
Disconnect the battery.
Remove the front RH lower splashshield, using tool [1].
Remove the accessories drive belt (see corresponding operation).
Uncouple and plug the diesel fuel delivery and return hoses. Support the engine, using a workshop hoist.
Remove the RH engine support.
Engage 5th gear to permit rotation of the engine. Remove the upper cover
(1).
Remove the intermediate cover (2).
Remove the lower cover (3).
WARNING:Refit the screw (4)equipped with a washer (5 mm thick).
Rotate the front RH wheel to drive the engine in its normal direction of
rotation. Bring the camshaft drive and injection pump pinions to their setting points.
Position the peg
[2](from underneath the vehicle).
Continue turning the engine until the peg [2]engages in the flywheel.

Setting the timing (continued).
NOTE:
If necessary, you can slightly rotate the pinions (10)and (7)anticlockwise in order to engage the belt.
The angular displacement value of the belt in relation to the pinions should not be more than half a tooth.
Remove tool
[5].
Act on the tensioner roller
(8)by its square «a», using tool [6]to check that the camshaft and injection
pump pinions can turn freely.
Position the belt tension instrument
[7]on the belt at «b».
Using tool
[6], act at «a»in the direction opposite to that of engine rotation, to obtain a tension value of
106 ± 2 SEEM units.
Tighten screws
(9), (5)and (6).
Remove tools
[7], [2], [3]and[4].
Rotate the crankshaft
8 timesin the normal direction of rotation.
Peg the flywheel, using tool
[2].
Peg the camshaft hub, using tool
[4].
Peg the injection pump hub, using tool
[3].
Slacken screws
(9), (5)and (6).
Position the belt tension instrument
[7]on the belt at «b».
Using tool
[6], act at «a»in the direction opposite to that of engine rotation, to obtain a tension value of
42 ± 2 SEEM units.

CHECKING AND SETTING THE VALVE TIMING
Engine: WJY
Setting the timing (continued).
Tighten:
Screw (9)to 2.1 ± 0.2 m.daN.
Screws (5)to 2,3 ± 0.2 m.daN.
Screws (6)to 2,3 ± 0.2 m.daN.
Remove and refit tool [7].
The tension value should be between 38 and 46 SEEM units.
Remove tools [7], [2], [3] and [4].
Turn the crankshaft 2 timesin the normal direction of rotation.
Peg the flywheel, using the peg [2].
Visually check the peggings of the camshaft and injection pump.
ESSENTIAL:Visually check that the offsets between the holes of
the camshaft and injection pump hubs and the correspondingpegging holes are not more than 1 mm.If necessary, recommence
the procedure for fitting the timing belt.
