1. Vehicles with parking heater. Unscrew the bolts (see arrows in illustration) fixing the heater pipe to the soundproof shield.
5.1. Unscrew the bolts (see arrows) fixing the heater pipe to the soundproof shield. Vehicles with parking heater
2. Unscrew the bolts/remove the clips 1-3 and 5 and remove the front part of the engine mudguard (see illustration).
5.2. Unscrew the bolts/remove the clips 1-3 and 5 and remove the front part of the engine mudguard
3. Remove the front bumper (see relevant chapter).
4. Set the top crossbar to the service position (see paragraphs 3.1-3.6).
5. Remove the timing belt from the camshaft gears (see relevant chapter).
6. Remove the right camshaft gear.
7. Remove the cylinder head cover.
8. Remove the bolts (see arrows in illustration) fasteners and remove the top 2, and then the right 1 and left 3 parts of the protective cover of the timing drive.
5.8. Unscrew the bolts (see arrows) fasteners and remove the top 2, and then the right 1 and left 3 parts of the protective cover of the timing drive
9. Unscrew the mounting bolts (see arrows in illustration), remove the nozzle holders, and then carefully remove the nozzles.
5.9. Unscrew the fastening bolts (see arrows), remove the nozzle holders, and then carefully remove the nozzles
10. Make sure that there are alignment marks on the camshaft bearing caps. If there are no marks, mark each bearing so that you can install them in their places during assembly. Start numbering the bearings from the flywheel side.
11. Loosen the camshaft bearing cap bolts, and then completely unscrew the bolts in a cross pattern and remove the bearing caps.
12. Remove the axis of the rocker arms, marking their mounting position.
13. Take a camshaft from a head of the block of cylinders together with an epiploon.
14. Label each pusher and remove the pushers by placing them in a box with numbered cells, since the pushers must be installed in their original places during assembly.
Installation
15. Check up a condition of surfaces of bearings and cams of a camshaft on deterioration and mechanical damages. If there is any damage, replace the camshaft with a new one.
16. Check the running surfaces of the bearings in the camshaft housing in the cylinder block, as well as the bearing caps for scoring or other damage. If any are found, replace the cylinder head with a new one.
17. Inspect the camshaft pushers and if there are scuffs, scratches, or other signs of wear, replace the pushers with new ones.
18. Make sure the crankshaft is locked with lock pin 3242 (see illustration 2.38).
19. Unscrew the pin (see arrow in illustration), located in front of the locking groove of the exhaust camshaft.
5.19. Unscrew the pin (see arrow), located in front of the locking groove of the exhaust camshaft
20. Establish persistent half rings of the axial bearing of a camshaft (see illustrations 5.0 and 5.0a).
21. Establish an axis of yokes.
22. Install the intake camshaft so that you can easily install the camshaft retainer, catalog number 3458 (see illustration).
5.22. Install the intake camshaft so that the camshaft retainer 3458 can be easily installed
23. Install and bolt covers 1 and 5 of the camshaft bearings, observing their marking and preventing displacement of the covers (see illustrations 5.23 and 5.23a).
5.23. Install the camshaft bearing caps, being careful not to dislodge the caps | 5.23a. Install and bolt covers 1 and 5 of the camshaft bearings |
24. Install the exhaust camshaft so that you can easily install the camshaft retainer, catalog number 3458 (see illustration 5.22).
25. Install and bolt covers 0 and 4 of the camshaft bearings (see illustration 5.23a).
26. Check again that the camshafts can be fixed with tool 3458 (see illustration 5.22).
Attention! Before installing the front and rear camshaft bearing caps, they must be sealed with sealant, for which follow these steps:
27. Completely remove the remnants of the old sealant from the contact surface of the cylinder head and camshaft bearing caps, then thoroughly clean the contact surfaces, they should be free of oil and grease.
28. Apply a thin layer of sealant to the hatched areas of the front left and rear right outer camshaft bearing caps (see illustration).
5.28. Apply a light coat of sealant to the hatched areas of the front left and rear right camshaft bearing outer caps
29. Apply a thin layer of sealant to the hatched areas of the rear left and front right outer camshaft bearing caps (see illustration).
5.29. Apply a thin layer of sealant to the hatched areas of the rear left and front right camshaft bearing outer caps
Attention! Keep sealant away from unshaded areas (see illustrations 5.28 and 5.29).
30. Install and bolt the remaining camshaft bearing caps 3, 2 and 6 (see illustration 5.23a).
31. Screw in the pin (see arrow in illustration 5.19), located in front of the locking groove of the exhaust camshaft.
Further, the installation of the dismantled components is carried out in the reverse order of removal.
