Dismantling

PERFORMANCE ORDER
1. To fix the engine on the corresponding bed.
2. To merge from the engine oil and to take the index of level of oil.
3. By means of the corresponding adaptation to unscrew the oil filter.
4. To unscrew bolts of fastening of a leading part of coupling, and then to remove a coupling disk.
5. To remove a flywheel.
6. To remove maple a belt of a drive of the generator and the pump of cooling liquid, the generator and its holder.
7. To remove a damper of krutilny fluctuations of a cranked shaft by means of the corresponding stripper.
8. To uncover the distributor and to unscrew spark plugs.
9. To take the distributor of ignition and to unscrew the holder of wires of a high voltage.
10. To uncover heads of the block of cylinders.
11. To remove the top and bottom covers kardanny chains of system of a gazoraspredeleniye.
12. To remove the tension device kardanny chains of the oil pump.
13. To unscrew bolts of fastening of an asterisk of the oil pump and to remove it together with a chain.
14. To disconnect top directing kardanny chains of system of a gazoraspredeleniye.
15. To unscrew two bolts of fastening of lateral system of a gazoraspredeleniye directing a kardanny chain.
16. To remove a spring clip of fastening of an axis of the tension device kardanny chains of system of a gazoraspredeleniye.
17. To take an axis of the tension device kardanny chains of system of a gazoraspredeleniye. by means of bolt М6x70 and the plug in length of 15 mm (see fig. Installation of a gazoraspredeleniye of the DOHC engine).
18. To remove the lever of the tension device of a chain.
19. To remove asterisks from cam-shafts.
20. To take top directing to a chain (up).
21. To remove a double asterisk from a cranked shaft.
22. To remove a driving chain of cam-shafts.
23. To take a pusher of the tension device of a chain.
24. To take two cam-shafts (designation of covers: "R" – a shaft of the inlet valves, as "L" – a shaft of final valves, numbers "1" – "5" – bearing number, considering from a drive of system of a gazoraspredeleniye).
25. To take hydraulic pushers of valves and to designate them so that in the course of assembly it was possible to establish them in those directing with which they cooperated.
Prevention

At extraction of pushers from directing it is impossible to use magnets as they can cause the wrong functioning of the valve in a pusher.


26. To remove rigid the pipeline of removal of air under a cover of a head of the block of cylinders.
27. To unscrew bolts of a head of the block of cylinders, unscrewing at first three forward bolts М8, and then bolts М11 upside-down in relation to their screwing up (see fig. Sequence of a tightening of bolts of a head of the block of cylinders of the DOHC engine), having originally weakened them on a half-turn.
28. To unscrew bolts with a nest of Torx of fastening of the oil pump and to remove the oil pump.
29. To unscrew the sensor of pressure of oil and the sensor of provision of a cranked shaft.
30. To remove the oil pallet after unscrewing of bolts of its fastening.
31. To remove the mesh filter of a maslopriyemnik of the oil pump and a partition of the oil pallet (the oil deflector).
32. To remove forward and back sealing rings of a cranked shaft.
33. To check designations of covers of radical bearings, to unscrew bolts of their fastening and to remove covers together with their loose leaves.
34. To take a cranked shaft. To pay attention, not to damage the gear sensor of impulses cooperating with the sensor of provision of a cranked shaft.
35. To take from the average bearing a persistent half ring of a cranked shaft and loose leaves of radical bearings from the block of cylinders and to designate them as appropriate.
