GENERAL INFORMATION

Sequence of dismantle of bolts of a head of cylinders

 


Sequence of an inhaling of bolts of a head of cylinders

 


Consecutive stages of an inhaling of bolts of a head of cylinders

 


Prevention

At dismantle of a head of cylinders or cases of a cam-shaft it is necessary to replace head laying. To turn on bolts of fastening of a head follows only on the cold engine. At assembly to use new bolts.


To remove or disconnect

PERFORMANCE ORDER
1. Bottom hose of a radiator.
2. To merge cooling liquid.
3. Negative wire of the storage battery.
4. A generator arm, previously having rejected the generator aside.
5. The distributor 14 with wires.
6. Cables from:
      – arm of the inlet pipeline;
      – butterfly valve cases;
      – the switch on the lowest transfer.
7. All vacuum hoses from the case of a butterfly valve and the inlet pipeline.
8. Hoses:
      – fuel (bringing and drain);
Prevention

Fuel pipelines are under pressure. Not to disconnect hoses before pressure reduction in fuel system.


      – hoses of system of cooling of the engine and a heater from the lower part of the case of a butterfly valve and a hose from an entrance branch pipe of the pump of a smyvatel;
      – a hose from a cover and a branch pipe of the 155th compulsory ventilation of a case of the engine from the case 8;
      – top hose of a radiator.
9. An exhaust pipe from the final pipeline.
10. Plug of the sensor of concentration of oxygen.
11. Electric wires:
      – cистемы of injection of fuel;
      – ignition cвечей.
12. Gear belt.
13. To unscrew bolts of fastening of a head of cylinders in the sequence shown on fig. Sequence of dismantle of bolts of a head of cylinders. (The engine should be cold).
14. Cam-shaft case 8.
15. A head of cylinders assembled with final and inlet pipelines 53, 23.

To clear

PERFORMANCE ORDER
1. To clear of oil and dirt the interfaced planes of a head, the case of a cam-shaft and the block of cylinders. On privalochny surfaces there should not be dents and deep scratches.
2. Fixing bolts of a head and carving openings in the block of cylinders should be pure. At dirt hit in openings the density of a joint of details can be broken at an inhaling of bolts by the nominal moment.

To establish or attach

PERFORMANCE ORDER
1. To impose the continuous 3-millimetric roller from hermetic on the condensed plane of the case of a cam-shaft.
2. A head of cylinders 29 and new laying 26 (to attach inlet and final pipelines if they were dismantled).
3. The cam-shaft case 8 on the top plate of a head of cylinders.
4. New fixing bolts of 4 heads of cylinders. At an inhaling of bolts to adhere to the sequence specified fig. Sequence of an inhaling of bolts of a head of cylinders.
4а. All bolts of fastening of a head 29th moment of 25 Nanometers.
4б. In addition to wrap bolts on 60 ° (see fig. Consecutive stages of an inhaling of bolts of a head of cylinders).
4в. In addition to wrap bolts on 60 °.
4г. In addition to wrap bolts on 30 °.
5. Hydrojacks 37 and levers 36.
6. Gear belt 44.
7. Plugs of electric wires:
      – cистемы of injection of fuel;
      – ignition cвечей.
8. An exhaust pipe to the final pipeline.
9. Plug of the sensor of concentration of oxygen.
10. Hoses:
      – top hose of a radiator;
      – hose of compulsory ventilation of a case;
      – a hose to the lower part of the case of a butterfly valve and a pressure head hose of the water pump;
      – fuel (bringing and drain).
11. To correct the provision of all vacuum hoses fixed to the case of a butterfly valve and the inlet pipeline.
12. Cables to:
      – to an arm of the inlet pipeline;
      – to the case of a butterfly valve of system of injection of fuel;
      – to the switch on the lowest transfer.
13. The distributor of ignition 14 with wires.
14. A generator arm, the generator, a belt to adjust a belt tension.
15. Bottom hose of a radiator.
16. Negative wire of the battery.
17. To fill in cooling liquid.
18. To start the Engine and to warm up it to temperature of opening of the thermostat.
19. To tighten bolts of fastening of a head in addition on ç0 °-50 ° in the sequence given on fig. Sequence of an inhaling of bolts of a head of cylinders.
