Krivoshipno-shatunnay mechanism

1–cranked shaft,

2–radical loose leaves,

3–cover of the radical bearing,


5–shatunny loose leaf,


7–piston rings

Gazoraspredeleniye system

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

1. To establish in an opening in a back part of a cranked shaft (adaptation 21.044) the bearing of a shaft of coupling.
2. To insert into nests in the block of cylinders dry semi-loose leaves of radical bearings.
3. To oil working surfaces of semi-loose leaves and to establish on them a cranked shaft.
4. To establish together with the oiled semi-loose leaves of a cover of radical bearings (see fig. of Krivoshipno-shatunnay the mechanism – shooters on covers of radical bearings should 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 axial люфт a cranked shaft.
6. To establish by means of the adaptation 21.011 A a new back sealing ring of a cranked shaft.
7. To cover a flute of a cover of a back sealant of a cranked shaft with pressurizing paste (No. A 70 SX-19554-BA) and to establish two halves of laying by means of a screw-driver with the blunted edge; red designation of laying should 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 to the block of cylinders an intermediate shaft and its persistent bearing; to establish a cover with a new sealing ring.
11. To establish on a cranked shaft a flywheel, tightening bolts (a carving to oil) flywheel fastenings by the corresponding moment.
12. By means of the adaptation 21.044 to center a coupling disk on a flywheel and to establish a leading part of coupling.
13. To oil cylinders and pistons with the piston rings established as appropriate.
14. To establish knots the piston – a rod in cylinders, compressing piston rings the special adaptation. Arrows on pistons to direct towards gazoraspredeleniye system (see fig. Gazoraspredeleniye system).
15. To establish shatunny loose leaves and covers of rods, tightening bolts the corresponding moment. To check axial люфт rods on shatunny necks.
16. To establish a power shaft of the oil pump and to screw the oil pump together with pipelines of supply of oil.


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


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

30. To adjust position of the generator, to establish 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 situation VMT is established, and to establish the ignition distributor.
33. To connect the vacuum pipeline to ignition system.
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 fig. Order of a 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 a high voltage.
38. To insert new laying and to screw up in the oil pallet a drain stopper.
39. To connect the elastic pipeline of ventilation of a case of the engine.
40. To insert the index of level of oil into its opening directing in the block of cylinders of the engine.
