8. Take out hydropushers of 5 valves. Mark them or lay so that not to mix at installation. It is necessary to store hydropushers in the same situation in what they were on the engine, otherwise from them oil will flow out.
9. Install the piston of the corresponding cylinder in VMT, then at compression of springs valves will rest against the piston.
10. Install the device for compression of springs of valves on a head and, having squeezed valve springs, take out crackers 6.
11. Remove a plate 7 and springs 8 and 9.
12. By means of a stripper remove an oil scraper cap.
13. Oil engine a new cap and insert it into a mandrel 3 (1 – the plug; 2 – oil scraper cap).

17. Having squeezed springs adaptation, establish valve crackers. After that strike with the hammer through a metal core a valve end face that crackers sat down on the place.
18. Similarly replace other caps.
19. Establish inserts 16 (see rice. A head of the block of the diesel engine of 1,9 l, 74 kW) according to earlier made marking also oil them engine.
20. Install in a head the camshaft so that cams of the first cylinder were directed up.
21. Establish washers 4.
22. Establish covers of the second and fourth bearings and evenly cross-wise wrap new bolts of their fastening. Tighten bolts the moment of 8 N · m also tighten for 90 °.
Prevention

At each removal of covers of bearings of the camshaft it is necessary to replace bolts of their fastening with new.


23. Apply sealant on a surface And covers of the first and fifth bearings, at the same time you watch that sealant did not get to the grooves specified by shooters rice. Places of putting sealant on the first and fifth covers of bearings of the camshaft. Then establish covers of the first, fifth and third bearings.
24. Establish all removed details upside-down. After installation of hydropushers of valves it is possible to launch the engine only in 30 min.
