Dismantling

PERFORMANCE ORDER
1. To fix the engine on a 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 клиновой a belt of a drive of the generator and the pump of a cooling liquid, the generator and its holder.
7. To remove демпфер крутильных fluctuations of a cranked shaft by means of a 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 propeller system chains timing.
12. To remove the tension device propeller 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 propeller system chains timing.
15. To unscrew two bolts of fastening lateral directing propeller system chains timing.
16. To remove a spring clip of fastening of an axis of the tension device propeller system chains timing.
17. To take an axis of the tension device propeller system chains timing. By means of bolt М6x70 and the plug in length of 15 mm (fig. Installation timing engine DOHC see).
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 (upwards).
21. To remove a double asterisk from a cranked shaft.
22. To remove приводную a chain of cam-shafts.
23. To take a pusher of the tension device of a chain.
24. To take two cam-shafts (a designation of covers: "R" – a shaft of inlet valves, "L" – a shaft of final valves, numbers "1" – "5" – bearing number, considering from outside a system drive timing).
25. To take hydraulic pushers of valves and to designate them so that in the course of assemblage them it was possible to establish in those directing with which they co-operated.
The prevention

At extraction of pushers from directing it is impossible to use magnets as they can cause 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 (fig. Sequence of a tightening of bolts of a head of the block of cylinders of engine DOHC see), originally having weakened them on a half-turn.
28. To unscrew bolts with nest Torx of fastening of the oil pump and to remove the oil pump.
29. To unscrew the gauge of pressure of oil and the gauge of position of a cranked shaft.
30. To remove the oil pallet after unscrewing of bolts of its fastening.
31. To remove the mesh filter маслоприемника the oil pump and a partition of the oil pallet (дефлектор oils).
32. To remove forward and back sealing rings of a cranked shaft.
33. To check up 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 gauge of impulses co-operating with the gauge of position 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 their appropriate amount.
