2. Remove yokes, pushers and hydrocompensators of gaps of valves.
3. Remove inlet and final collectors.
4. To mark valves before dismantling.
5. Remove valves, using the device for compression of springs. Squeeze a spring and to take out crackers. After that to release a spring and to take out the valve.
6. To take out the screw-driver an oil scraper cap.
7. Remove the rotary device of the final valve and a steel washer of the inlet valve.

8. Establish an adjusting washer of the inlet valve and an oil scraper cap in deepening.
9. Check correctness of provision of an adjusting washer.


At the wrong installation of an adjusting washer of the inlet valve height of its spring decreases by 2,6 mm. The fact that the spring is displaced to the block of cylinders is a consequence of it, and it leads to damages of the camshaft.

10. Establish to the place of a spring and valves.
11. Squeeze springs by means of adaptation and to insert crackers.
12. To move apart springs.
13. To insert hydrocompensators of gaps.
14. At installation of yokes to watch that one galtel sat down on another.
15. Establish yokes. Cover their contact surfaces with paste on the basis of MoS2.
16. Establish inlet and final collectors with new laying on a head of cylinders and to tighten bolts the moment of 22 Nanometers.
