THE GENERAL DATA

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

 


The prevention

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


To remove or disconnect

PERFORMANCE ORDER
1. The bottom hose of a radiator.
2. To merge cooling liquid.
3. A negative wire of the storage battery.
4. A generator arm, preliminary having rejected the generator aside.
5. The distributor 14 with wires.
6. Cables from:
      – An arm of the inlet pipeline;
      – Cases throttle заслонки;
      – The switch on the lowest transfer.
7. All vacuum hoses from the case throttle заслонки and the inlet pipeline.
8. Hoses:
      – Fuel (bringing and drain);
The 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 bottom part of the case throttle заслонки and a hose from an entrance branch pipe of the pump смывателя;
      – A hose from a cover and a branch pipe 155 compulsory ventilations картера the engine from the case 8;
      – The top hose of a radiator.
9. An exhaust pipe from the final pipeline.
10. The plug of the gauge of concentration of oxygen.
11. Electric wires:
      – cистемы fuel injection;
      – cвечей ignitions.
12. A 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. The case 8 cam-shafts.
15. A head of cylinders in gathering with final and inlet pipelines 53, 23.

To clear

PERFORMANCE ORDER
1. To clear of oil and a dirt interfaced planes of a head, the case of a cam-shaft and the block of cylinders. On привалочных surfaces there should not be dents and deep scratches.
2. Fixing bolts of a head and carving apertures in the block of cylinders should be pure. At dirt hit in apertures 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 platen from hermetic on a condensed plane of the case of a cam-shaft.
2. A head of cylinders 29 and a new lining 26 (to attach inlet and final pipelines if they have been dismantled).
3. The case 8 cam-shafts 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 in fig. Sequence of an inhaling of bolts of a head of cylinders.
4а. All bolts of fastening of a head 29 moment of 25 Nanometers.
4б. In addition to wrap bolts on 60 (fig. Consecutive stages of an inhaling of bolts of a head of cylinders see).
4в. In addition to wrap bolts on 60 .
4г. In addition to wrap bolts on 30 .
5. Hydrojacks 37 and levers 36.
6. A gear belt 44.
7. Plugs of electric wires:
      – cистемы fuel injection;
      – cвечей ignitions.
8. An exhaust pipe to the final pipeline.
9. The plug of the gauge of concentration of oxygen.
10. Hoses:
      – The top hose of a radiator;
      – A hose of compulsory ventilation картера;
      – A hose to the bottom part of the case throttle заслонки and a pressure head hose of the water pump;
      – Fuel (bringing and drain).
11. To correct position of all vacuum hoses fixed to the case throttle заслонки and the inlet pipeline.
12. Cables to:
      – To an arm of the inlet pipeline;
      – To the case throttle заслонки systems 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. The bottom hose of a radiator.
16. A 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 З0 –50 in the sequence resulted on fig. Sequence of an inhaling of bolts of a head of cylinders.
