Fig. 3.49. Alignment of timing marks on the camshaft pulley and crankshaft pulley with the corresponding fixed marks when setting the piston of the 1st cylinder to TDC of the compression stroke (arrows indicate the working branches of the belt): 1 – installation marks; 2 – camshaft pulley; 3 – water pump pulley; 4 – crankshaft pulley; 5 – installation marks; 6 – bolt, 24 Nm; 7 – belt tensioner for gas distribution mechanism drive
13. Turn the crankshaft clockwise until the timing marks on the camshaft pulley and the crankshaft pulley align with the corresponding fixed marks and set the piston of the 1st cylinder to TDC of the compression stroke (Fig. 3.49).
Caution: Always turn the crankshaft clockwise only.
14. Loosen the timing belt tensioner adjusting bolt.

15. Using a screwdriver, push the timing belt tensioner completely back (in the direction of the arrow), as shown in Fig. 3.50.
16. Temporarily tighten the adjusting bolt.
17. Remove the timing belt.
Attention! If the timing belt is reused, it is necessary to apply an arrow with chalk on the reverse (non-working) surface of the belt indicating the direction of rotation (right).
Installation
Installation is carried out in the reverse order of removal, taking into account the following.
1. Insert a screwdriver as shown in Fig. 3.50, fully move back (in the direction of the arrow) the timing belt tensioner, and then temporarily tighten the adjusting bolt.
2. Align the timing marks on the crankshaft and camshaft pulleys with the corresponding fixed marks.
3. Making sure that the working branch (side) of the belt is tensioned, install the timing belt in the following order:
- crankshaft pulley;
- water pump pulley;
- camshaft pulley;
- tensioner roller.
After installing the timing belt, try to turn the crankshaft pulley counterclockwise with force, and then check the belt tension and the alignment of the timing marks.
4. Loosen the tensioner pulley adjusting bolt 1/2 to 1/4 turn to allow the tensioner spring to move the pulley and tension the belt.
5. Turn the crankshaft clockwise 2 turns and make sure that the timing marks are aligned (see Fig. 3.49).
Caution! Since the purpose of this operation is to ensure the correct tension of the timing belt due to the torque generated by the camshaft lobes, it is necessary to turn the engine crankshaft only clockwise. Never turn the crankshaft counterclockwise.

6. It is necessary to check that the timing belt teeth do not protrude above the camshaft pulley in sector A, indicated in Fig. 3.51, and that it is correctly engaged on both pulleys. After this, tighten the tensioner roller adjusting bolt to the appropriate torque.
Fig. 3.52. Flange location: A - front part of the engine; 1 – crankshaft pulley; 2 – crankshaft; 3 – flange
7. Install the flange as shown in Fig. 3.52.
8. Install the lower left protective cover.
9. Install the engine mount bracket.
10. Install the crankshaft pulley.
