13. To establish a forward cover of the block of cylinders.
14. To establish маслоотражатель and маслозаборную a tube with a new lining.
15. To establish a new lining in flutes oil картера.
16. To put hermetic on the sites interfaced to a cover of a sealing ring.
17. To establish oil картер.
18. To establish on a cranked shaft a flywheel, tightening bolts (a carving to oil) flywheel fastenings by the corresponding moment.
19. By means of the adaptation to centre a coupling disk on a flywheel and to establish a leading part of coupling.
20. To establish the gauge of position of a cranked shaft and the gauge of pressure of oil.
21. To establish into place the oil pump and to tighten fastening bolts the corresponding moment.
22. To establish the oil filter and the water pump.
23. To establish on the block of cylinders a new lining.
24. To turn a cranked shaft so that pistons were established in the middle of the course.
25. To establish a head of the block of cylinders on the block of cylinders.
26. To grease with a thin layer of engine oil a carving of bolts of fastening of a head of the block of cylinders, to establish them into place and to tighten the demanded moment in certain sequence (subsection 3.2.1 see).
27. To grease with a thin layer of engine oil of a support of camshafts in a head and to establish into place camshafts.
28. To grease with a thin layer of engine oil of a cover of bearings of camshafts and to establish them into place according to marks. Covers of bearings of a camshaft operating inlet valves have marks R1–R5, and covers of bearings of a camshaft operating final valves have marks L1–L5. Numbering of covers from outside a mechanism drive timing.
29. To establish the pipeline of giving of oil to cams of camshafts.
30. Gradually and consistently to tighten nuts of fastening of covers of fastening of camshafts in certain sequence. By hand to tighten fastening nuts, turning them it is consecutive on 180 before contact of a cover with a head of the block of cylinders. Sequence of a tightening: L1 and R1, L5 and R5, L3 and R3. Then to screw up by hand other nuts of fastening of covers.
31. To tighten nuts of fastening of covers the demanded moment, turning them on the same corner in the following sequence: L1 and R1, L5 and R5, L3 and R3, L2 and L4, R2 and R4.
32. To check up that the cranked shaft is in position corresponding to installation of the piston of the cylinder 1 in the top dead point in a compression step, thus шпоночный the groove should be directed downwards.
The prevention

On a chain газораспределительного the mechanism there are copper elements which are used for a correct arrangement of the mechanism timing at chain installation.


33. To lower a chain from above in a casing, thus a single copper link of a chain should be below.
34. To insert шпонку into a groove of a cranked shaft.
35. To establish a chain on an internal (big) asterisk, having combined thus a copper link of a chain with a label on an asterisk.
36. To establish an asterisk on a cranked shaft, having combined a groove on an asterisk with шпонкой, thus the label on an asterisk should be strictly below.
37. To insert from above into place bottom успокоитель chains and to screw its bolts which carving is covered by the means interfering unscrewing of bolts.
38. To establish a hydraulic pusher натяжителя chains.
39. To establish the lever натяжителя chains, a lever axis натяжителя and to fix its lock washer.
