Removal the timing belt of the gas distribution mechanism drive
Caution: Do not turn the engine crankshaft against the normal direction of rotation.
1. Place the vehicle on a two-post lift.
2. Disconnect the negative battery terminal.
3. Remove the front right wheel from the vehicle.
4. Remove the front right fender liner.
5. Remove the engine protective pan.
6. Remove the engine thrust rod.
7. Install the engine support (Mot. 1367-02).
8. Remove the right engine mounting support.
9. Remove the accessory drive belts.
10. Remove the crankshaft pulley, securing the flywheel from turning with a screwdriver.
11. Remove the timing gear covers (1) and (2).
12. Set the engine to the TDC position using the special installation pin (Mot. 1054), aligning the mark (3) on the crankshaft sprocket with the mark (4).
13. Loosen the tension roller nut.
14. Remove the timing belt of the gas distribution mechanism drive.
Adjusting the valve timing
1. Install the new tension roller, making sure that the rib (5) is correctly positioned between the two shoulders of the tension roller (6) and the pin (7) of the tension roller is inserted correctly.
Caution: Do not remove the tension roller retaining pin (7) until the timing belt has been installed.
2. Tighten the tension roller fastening nut by hand until it contacts the tension roller.
3. Make sure that the TDC alignment pin (Mot. 1054) is in place.
4. Make sure that the timing mark on the sprocket (8) is opposite the mark (9) on the oil pump housing.
5. Make sure that the mark on the camshaft pulley (10) is opposite the mark (11) on the rocker arm cover.
6. Install the crankshaft pulley bolt and washer to secure the sprocket in place.
Installing the timing belt
Caution: The timing belt must be replaced with a new one after each removal. In addition, the tension roller and crankshaft pulley bolt must also be replaced with new ones.
1. Install the timing belt, aligning the marks on the belt with the marks on the camshaft and crankshaft sprockets.
2. Remove the TDC alignment pin and tension roller pin.
3. Using Allen key (hexagon) 6 mm turn the eccentric tension roller counterclockwise until the tension roller pointer is set to the position shown in the figure (12).
4. Tighten the tension roller nut to 24 Nm.
5. Turn the crankshaft six turns clockwise (from the timing drive side).
6. Re-insert the TDC pin (Mot. 1054) into the flywheel bore and ensure that the timing marks on the camshaft and crankshaft align with the fixed marks on the engine.
7. Remove the TDC alignment pin.
Note: It is important to tighten the tension roller nut to the specified torque to avoid damaging the roller, and at the same time to prevent it from becoming loose, which may cause serious damage to the engine
8. Loosen the tension roller nut no more than one turn, holding the roller itself in place with an Allen key (hexagon) 6 mm, then turn the tension roller pointer clockwise (13) to center it in the installation window (14).
9. Tighten the tension roller nut to 24 Nm.
10. Make sure that the tension roller does not touch the cylinder head at point (15).
Attention:
If the tension roller touches the cylinder head:
- set the engine to TDC,
- remove the tension roller and timing belt,
- reinsert the tension roller pin,
- repeat the timing belt check procedure from the beginning.
11. Remove the crankshaft pulley bolt
12. Install the lower timing drive cover.
13. Tighten the intermediate timing cover mounting bolts to a torque of 10 Nm.
14. Tighten the upper timing cover mounting bolts in the sequence shown in the figure to a torque of 33 Nm.
15. Having secured the flywheel with a screwdriver, tighten the crankshaft pulley bolt to a torque of 40 Nm, then tighten it another 150±6', using for this purpose the magnetized lever of the cylinder head tightening indicator (Mot. 591-02) and a key for angular tightening of the cylinder head (Mot. 591-04).
16. Install the right engine mounting support and tighten the mounting bolts to 62 N·m.
17. Tighten the engine torque rod bolt to 105 Nm.
18. Tighten the torque rod support mounting bolt on the subframe to a torque of 62 N·m.
19. Further installation is carried out in the reverse order of removal.
20. Connect the negative battery terminal.
