4.1.9. Assembly of the engine


Krivoshipno-shatunnay mechanism

1 – bent shaft,

2 – radical inserts,

3 – cover of the radical bearing,

4 – rod,

5 – connecting rod,

6 – piston,

7 – piston rings

System of gas distribution

1 – pulley of a bent shaft,
2 – gear belt,
3 – pulley of an intermediate shaft,
4 – intermediate shaft,
5 – cam-shaft pulley,
6 – cam-shaft,
7 – valve lever,
8 – valve lever spring,
9 – a bolt with a spherical tip (a valve lever support),
10 – valve,
11 – tension device of a gear belt

1. To install in an opening in a back part of a bent shaft (adaptation 21.044) the coupling shaft bearing.
2. To insert into nests in the block of cylinders dry semi-inserts of radical bearings.
3. To oil working surfaces of semi-inserts and to establish on them a bent shaft.
4. To establish together with the oiled semi-inserts of a cover of radical bearings (see the fig. Krivoshipno-shatunnay the mechanism – shooters on covers of radical bearings have to be sent towards a pulley on cranked to a shaft).
5. To tighten bolts of covers of radical bearings the corresponding moment and to measure an axial side play of a bent shaft.
6. To establish a new back sealing ring of a bent shaft by means of adaptation 21.011 A.
7. To cover a flute of a cover of a back sealant of a bent shaft with the pressurizing paste (No. A 70 SX-19554-BA) and to establish two halves of laying by means of the screw-driver with the blunted edge; red designation of laying has to be directed to a bearing cover.
8. To establish a forward cover of the block of cylinders together with new laying.
9. To establish a new forward sealing ring (adaptation 21.009 A).
10. To attach an intermediate shaft and its persistent bearing to the block of cylinders; to establish a cover with a new sealing ring.
11. To establish a flywheel on a bent shaft, tightening bolts (to oil a carving) fastenings of a flywheel the corresponding moment.
12. By means of adaptation 21.044 to center a clutch plate on a flywheel and to establish the leading part of coupling.
13. To oil cylinders and pistons with the established appropriately piston rings.
14. To install knots the piston – a rod in cylinders, squeezing piston rings special adaptation. To direct arrows on pistons towards system of gas distribution (see rice. System of gas distribution).
15. To establish connecting rods and covers of rods, tightening bolts the corresponding moment. To check an axial side play of rods on conrod necks.
16. To establish a power shaft of the oil pump and to screw the oil pump together with oil supply pipelines.


In case of installation of the new pump it is necessary to fill it with oil and to turn several times a hand its power shaft.

17. To establish the new laying (greased with the pressurizing paste) in flutes of covers of radical bearings of a bent shaft (back and forward), to insert new laying of the oil pallet and to press them into flutes.
18. To install the oil pallet and to tighten its bolts in three stages, since a bolt (A), in the direction of a bolt (V), and then from a bolt (V) to a bolt (And).
19. To establish a pusher of the drive of the fuel pump and the fuel pump with laying.
20. To establish an oil settler (to record it Loctite glue).
21. To install the pump of cooling liquid.
22. To establish an oil filter together with laying. The case of an oil filter should be tightened a hand to a contact, and then on 3/4 turns.
23. To screw up the oil pressure sensor.
24. To establish a pulley on a bent shaft (the strengthened party in the direction of a flywheel).
25. To screw in in the block of cylinders on the place of bolts No. 7 and 9 (see rice. Order of tightening of bolts of a head of the block of cylinders), the pins aligning a head of the block of cylinders (see subsection To establish laying of a head of the block of cylinders by the inscription directed up.
26. To install in the 1st cylinder the piston in the top dead point (TDP) and a cam-shaft pulley so that to receive combination of adjusting signs (see rice. Adjusting signs of system of gas distribution).
27. To establish a head of the block of cylinders, to insert (except bolts No. 7 and 9 – see rice. An order of tightening of bolts of a head of the block of cylinders) and slightly to tighten head bolts, to take the bolted aligning pins and on their place to screw in the remained two bolts. To tighten respectively bolts of fastening of a head of the block of cylinders (see subsection
28. To establish on a bent shaft a pulley (the concave party outside), a gear belt and its casing (see subsection
29. To install elastic pipelines of the cooling system and to adjust a tension of a gear belt.


From this point the bent shaft should be rotated only in the direction of its rotation in operating time of the engine.

30. To adjust position of the generator, to install the pump of cooling liquid and the fan.
31. To establish a pulley of the generator and to pull maple a belt so that its deflection made 10 mm (A) (1 – a bolt of the tension device).
32. To check whether the piston of the 1st cylinder in the provision of VMT is installed and to install the ignition distributor.
33. To connect the vacuum pipeline to system of ignition.
34. To check and in case of need to adjust a gap of valves.
35. To establish a cover of a head of the block of cylinders, paying attention to the correct arrangement of its laying.
36. To tighten bolts of fastening of a cover of a head of the block of cylinders in the corresponding sequence (see rice. Order of tightening of bolts of a cover of a head of the block of cylinders).
37. To screw up in a head of the block of cylinders of a spark plug and to connect wires of high voltage.
38. To insert new laying and to screw up a drain stopper in the oil pallet.
39. To connect the elastic pipeline of ventilation of a case of the engine.
40. To insert the index of level of oil into an opening of its guide in the block of cylinders of the engine.
