Sequence of a tightening of bolts of a head of the block of cylinders


Installation of system of a gazoraspredeleniye


1–the adaptation for installation of a cam-shaft,

2–the adaptation for installation of the fuel pump,

3–an opravka for installation of a cranked shaft in situation VMT,

4–roller of the tension device of a gear belt of a drive of system of a gazoraspredeleniye

Arrangement of a groove of a cam-shaft at installation of a head of the block of cylinders


Before installation of a head it is necessary to be convinced that the groove on the end of the clown of a cam-shaft is established horizontally (parallel to the bottom plane of a head of the block of cylinders), and big on height the part of the clown is directed up.

Prevention

Surfaces of a prileganiye of laying of the block of cylinders and a head should be smooth, pure, without scratches and damages. To check a condition of the bottom surface of a head of the block of cylinders, this surface is not under repair (not перешлифовывается).


PERFORMANCE ORDER
1. To measure a vystupaniye of pistons over the top plane of the block of cylinders.
2. Depending on a vystupaniye of pistons to pick up the corresponding thickness of laying of a head (see subsection 3.2.1.2.2).
3. To establish on the block of cylinders head laying so that the party with an inscription of "TOP" was from above.
4. To establish a head on the block of cylinders.
5. To insert into the corresponding openings of a head of the block of cylinders fastening bolts.

Prevention

At installation of a head of the block of cylinders it is necessary to use new bolts of fastening.


6. To tighten bolts of fastening of a head of the block of cylinders the corresponding moment (see subsection 3.2.1.2.9) in the corresponding sequence (see fig. Sequence of a tightening of bolts of a head of the block of cylinders).
7. In later versions of the engine 1,8 of dm3 are used other type of bolts of fastening of a head of the block of cylinders which have carving М12 and Torx T70 type heads. These bolts should be tightened in the same sequence, as bolts of old type (see fig. Sequence of a tightening of bolts of a head of the block of cylinders) next moments:
      – 1 stage: 10 Nanometers;
      – 2nd stage: 100 Nanometers;
      – 3rd stage: to unscrew a bolt "1" on 180 °;
      – 4th stage: to tighten a bolt "1" moment of 70 Nanometers;
      – 5th stage: to tighten a bolt "1" in addition on 120 °.
      – 6th stage: to tighten in the above described way (stages 3-5) other bolts, observing the correct sequence of a tightening.
8. To screw up in a head of the block of cylinders of a glow plug, tightening them the corresponding moment, and to connect their electric wires.
9. To screw up in a head of the block of cylinders of a nozzle together with new washers of thermal isolation, the convex party directed to a head.
10. To establish a back right casing of a drive of system of a gazoraspredeleniye with a roller of the tension device.
11. To establish a back left casing together with an average pulley. To check, whether there is a rubber ring of the elastic pipeline in the place provided for it on a casing.
12. To establish a pulley of a cam-shaft and to insert the adaptation (1) (see fig. Installation of system of a gazoraspredeleniye).
13. To check, whether the cranked shaft of the engine of an opravka (3) in position VMT of the piston of the 1st cylinder concerns.
14. To establish a new gear belt of a drive of system of a gazoraspredeleniye.
15. To pull a gear belt of a drive of system of a gazoraspredeleniye as follows. To weaken a bolt of fastening of a pulley to a cam-shaft, then to unscrew on a turn floor a bolt of a roller of the tension device. The roller of the tension device under the influence of a spring will move to a gear belt of a drive of system of a gazoraspredeleniye, and then tighten all above-named bolts.
16. To take all adjusting adaptations.
17. To turn a cranked shaft on two complete revolutions in the direction of its working rotation and to establish it in situation in which cut of a pulley of the fuel pump is in a position "12 hours".
18. To turn a cranked shaft in the opposite direction and to establish cut of a pulley of the fuel pump in a position "11 hours".
19. In a control opening of the block of cylinders to screw up an opravka for piston 1 installation. the cylinder in VMT and carefully to rotate a cranked shaft of the engine (in the direction of its working rotation) against the stop in an adjusting opravka.
20. To insert the adjusting adaptation of a pulley of a cam-shaft into the opening provided for it (see fig. Installation of system of a gazoraspredeleniye).
21. To unscrew on one turn bolts of fastening of an average pulley and a roller of the tension device; then to push away a piece of a gear belt from the opposite side of a roller of the tension device in its direction and to release a belt.
22. To tighten all bolts of fastening.
23. To take all adjusting adaptations, then to screw up a stopper in a control opening of an adjusting opravka in the block of cylinders of the engine.
24. To establish a casing of a drive of system of a gazoraspredeleniye.
25. To establish and pull maple a belt of a drive of the generator.
26. To establish maple a belt of a drive of the pump of cooling liquid.
27. To connect to the block of cylinders of the engine a returnable oil pipeline from a turbokompressor.
28. To screw a forward exhaust pipe.
29. To screw a bracket of an exhaust pipe on a transmission cross-piece.
30. To establish new laying and to connect the pipeline of supply of oil to the pump and a turbokompressor.
31. To connect to an inlet collector the vacuum pipeline screwed on the fuel pump.
32. To check and in case of need to adjust a gap of valves.
33. To establish a cover of a head of the block of cylinders together with laying.
Then to execute other actions in sequence of return in relation to process of removal of a head of the block of cylinders, paying attention on:
      – observance of the corresponding moments of a tightening of bolts and nuts;
      – installation of new laying of a cover of the thermostat;
      – air removal from fuel system;
      – filling of system of cooling and air removal from it;
      – check of tightness of all connections.
