Installation
Note: The pistons should be at half stroke during adjustment at the check point.
Note: The key must be at the top (vertical position): 90° to the position at the control point for overlapping the intake and exhaust valves in cylinder No.1.
Check the tightness of the sealing bushings at the oil pump and camshaft level. Make sure that the rollers and coolant pump rotate freely without gaps or scoring.

Also make sure that the rollers do not make noise and/or do not spray grease.
Also check the surface condition of these rollers.
Install and tighten well in the following order:
1. Timing belt pulley.
2. Guide roller.
3. Camshaft pulley (making sure that the belt is pressed tightly against the roller).
4. High pressure pump.
5. Cooling system pump.
6. Tension roller.
Note: Make sure the back of the belt is pressed tightly against the idler pulley and that the belt branch between the crankshaft pulley and the camshaft pulley has only 33 free teeth.
Loosen the tension roller bolt (7).
Use the hex key to move the tensioning roller pointer (8) to the middle of the control area "B". by turning the tensioner counterclockwise.
Tighten the tension roller bolt (7).
Remove tools 1 and 2. Make sure that the timing pulley is pressed tightly against the crankshaft, turn the crankshaft 10 revolutions.
Install accessories 1 and 2.
Make sure that the index (8) on the dynamic tensioner is correctly positioned, otherwise repeat the timing belt installation operation.
Remove tools 1 and 2.
Reinstall:
- engine stop mechanism bracket (3);
- speed sensor (2);
- right intermediate engine mount (4);
- assembly of engine support (5) and travel limiter fixing bracket (6);
- lower casing of the timing mechanism;
- tool 3 for flywheel;
- attachment drive pulley;
- then perform a 180° angle tightening.
Remove device 3.
Install the accessory drive belt.
Proceed in the reverse order of removal.
