Removal
1. Loosen the screws and remove the valve cover. Tightening torque: 8-12Nm.
2. Remove the right front wheel. Tightening torque: 88-98 Nm,
3. Unscrew 2 screws (1) and remove the right engine mudguard (2).
4. Loosen the coolant pump pulley mounting screws without unscrewing them.
5. Remove the drive belts of the generator (3), air conditioning compressor (4) and power steering pump (5).
6. Unscrew 4 screws and remove the coolant pump pulley.
7. Unscrew 4 screws (6) and remove the upper timing belt cover (7). Tightening torque: 8-10 Nm.
8. Turn the crankshaft and align the pulley spline with the "T" mark on the timing belt cover.
9. Check the alignment of the TDC marks of the compression stroke of the 1st cylinder on the camshaft pulley and the cylinder head cover
10. Loosen the screws and remove the pulley (8). Tightening torque: 137-147 Nm.
Note: When installing, align the flange pin with the pulley groove.
11. Remove the flange from the crankshaft (9).
12. Unscrew 4 screws (10) and remove the lower timing belt cover (11). Tightening torque: 8-10 Nm.
13. Remove the timing belt tensioner (12).
14. Remove the timing belt.
Note: When reinstalling the belt, mark its direction of rotation.
15. Unscrew the screw (13) and remove the idler pulley (14).
16. Remove the crankshaft toothed pulley (15).
Examination
17. Check the pulleys for wear and damage. Replace them if necessary.
18. Check the tensioner roller for ease of rotation and absence of wobble or noise.
19. Replace the rollers if there are grease leaks from the bearings.
20. Check the belts for damage, traces of oil or coolant. Remove minor contamination with a rag or paper, without using solvents.
Caution: Do not twist or bend the timing belt. Keep the belt clean and free of grease or fuel.
Installation
21. Install the crankshaft toothed pulley.
22. Align the TDC marks of the compression stroke of the 1st cylinder on the pulley (16) of the camshaft and on the pulley (17) of the crankshaft.
Note: The TDC mark on the toothed pulley of the camshaft is made in the form of a through hole, through which, when the position of the camshaft is correctly set, which corresponds to the TDC of the piston of cylinder No.1, you can see the mark applied to the cylinder head.
The mark on the toothed pulley of the crankshaft is applied to the end surface of the tooth, this mark is also repeated on the rear flange of the toothed pulley in the form of a notch. These marks must coincide with the mark in the form of a protrusion on the cylinder block.
23. Install the guide roller (A) and tighten the mounting screw (B). Tightening torque: 42-54 Nm.
24. Install the timing belt tensioner (18) without tightening the screw.
25. Install the timing belt on the pulleys in the following sequence: crankshaft (19) -> guide roller (20) -> camshaft (21) ->tensioning device (22).
26. Press the tensioner roller (23) in the direction of the arrow to perform the initial belt tension
27. Check the position of the belt on the pulleys and tighten the screws (24 and 25) of the tensioner. Tightening torque 20-26 Nm.
Checking the belt tension
28. Using your thumb, press the belt at the indicated point with a force of 49 N and make sure that the top of the belt tooth is located at a distance of 1/2 of the radius of the circle inscribed in the head from the center of the screw head.
29. Turn the crankshaft clockwise two turns and check the alignment of the TDC marks on the crankshaft and camshaft pulleys.
30. Further installation is carried out in reverse order.
