PERFORMANCE ORDER
1. To disconnect from the accumulator a weight wire.
2. To remove maple a belt of a drive of the generator and the pump of cooling liquid.
3. In the carburetor engine to remove the air filter.
4. In the version with injection of fuel to remove the pipeline of supply of air from the filter to the butterfly valve case.
5. To remove wires of a high voltage, to unscrew spark plugs, a cover of the distributor of ignition and a distributor rotor.
6. To disconnect the pipeline of ventilation of a case from a cover of a head of the block of cylinders.
7. To disconnect a cable of a pedal of an accelerator. In the carburetor the engine to unscrew a butterfly valve cable together with the holder, and in the engine with injection of fuel to disconnect draft from the butterfly valve case after extraction from a clip from an artificial material.
8. To uncover heads of the block of cylinders (11 bolts and 4 nuts).
9. To remove the ignition distributor.
10. To remove the top casing kardanny chains of system of a gazoraspredeleniye.
11. To establish the piston in the N1 cylinder in VMT.
Prevention

It is possible to turn a cap key for an average bolt of fastening of an asterisk a cranked shaft in the direction of its working rotation while signs on asterisks of cam-shafts will not be established at height of the top plane of a head of the block of cylinders and in both cam-shafts will be directed outside.


12. To unscrew a nut of fastening of an asterisk of a cranked shaft.
13. By means of a stripper to remove an asterisk from a cranked shaft. In case of need to remove and a radiator.
14. To remove the bottom casing kardanny chains of system of a gazoraspredeleniye.
15. To remove the tension device kardanny chains of the oil pump.
16. To unscrew a bolt with a nest of Torx of fastening of an asterisk of a drive of the oil pump and to remove an asterisk together with a chain.
17. To remove, held by a spring hook, top directing kardanny to a chain of system of a gazoraspredeleniye.
18. To unscrew the top and bottom bolts of lateral system of a gazoraspredeleniye directing a kardanny chain.
19. To remove a lock ring of the tension device, and then to remove the tension device kardanny chains of system of a gazoraspredeleniye.
20. To take an axis of the tension device of a chain by means of bolt М6Ч70 and plugs in length of 15 mm.
21. To remove asterisks from both cam-shafts. To designate them that in the course of assembly to put on the corresponding places.
22. To take up lateral directing to a chain.
23. To remove an asterisk from a cranked shaft.
24. To take up a driving chain of system of a gazoraspredeleniye.
25. To remove the tension device of a chain.
26. To remove a hydraulic pusher of the tension device of a chain.
Prevention

After removal kardanny the chain cannot turn a cranked shaft.


27. To disassemble a hydraulic pusher of the tension device and to merge oil.
28. By means of the special adaptation 21.145 to collect the hydraulic pusher of the tension device filled with oil for the engine. For this purpose it is necessary to establish the pusher case the flat party on a workbench, and on it the adaptation plug a cone up. To establish the pusher piston on the plug and to compress everything together the lever of the adaptation which publishes a characteristic sound after a dozhatiya against the stop (in the lowest situation).
29. To check, whether there is a piston of the 1st cylinder in VMT (the flute of a cranked shaft is directed down).
30. To put on a chain a cranked shaft. To check correctness of connection with cranked shaft.
31. To establish lateral directing to a chain.
32. To establish a hydraulic pusher of the tension device of a chain.
33. To establish the tension device of a chain.
34. To insert the tension device of a chain together with a lock ring.
35. To establish cam-shafts in the situation shown on fig. Installation of a gazoraspredeleniye of the DOHC engine – shponochny flutes of both shaft should be directed horizontally outside of a head of the block of cylinders.
36. To put on a driving chain of system of a gazoraspredeleniye asterisks of cam-shafts.
37. To establish on asterisk cam-shafts together with a chain so that the designated link of a chain settled down opposite to a sign on an asterisk of a cranked shaft (see the lower part fig. Installation of a gazoraspredeleniye of the DOHC engine).
Prevention

In an installation time of asterisks the driving chain should be tense from the opposite side of the tension device.


38. For the forward end of a cam-shaft of inlet valves to put on elements of a drive of the distributor of ignition.
39. To turn a cranked shaft on some turns (in the working direction).
40. To establish the piston in the N1 cylinder in VMT and to check, whether shponochny flutes of asterisks of cam-shafts (fig. are established horizontally outside of a head of the block of cylinders. Installation of a gazoraspredeleniye of the DOHC engine).
41. To establish top directing to a chain.
42. To put on a driving chain of the oil pump an asterisk on cranked to a shaft, and then to establish an asterisk (with the chain put on on it) on a shaft of the oil pump, paying attention, that "FRONT" inscription on an asterisk was on outer side (was visible).
43. To establish the tension device kardanny to chains of the oil pump.
44. To establish an asterisk groove according to a flute of a cranked shaft.
45. To establish the bottom casing kardanny to chains of system of a gazoraspredeleniye together with new laying, to screw up bolts of its fastening, but not to tighten them.
46. To put on a pulley a cranked shaft and to tighten a nut of its fastening the corresponding moment.
47. To tighten bolts of fastening of the bottom casing kardanny chains of system of a gazoraspredeleniye the corresponding moment.
48. To execute further actions in return sequence in relation to removal process, paying attention on:
       – installation of new laying of the top casing kardanny chains of system of a gazoraspredeleniye;
        – the correct sequence of a tightening of bolts of a cover of a head of the block of cylinders, since extreme, and finishing on averages;
        – observance of the necessary moments of a tightening of the corresponding carving connections;
        – filling by liquid and air removal from system of cooling of the engine after the completion of installation;
        – check of control parameters of idling of the engine.
