 Removal

PERFORMANCE ORDER
1. Disconnect a wire from the negative plug of the storage battery.
2. Remove pressure in fuel system.
3. Merge cooling liquid from cooling system.
4. Merge engine oil from the engine.
5. Remove a hose of positive ventilation of a case and a ventilation hose.
6. Disconnect a cable of an accelerator and, at existence, a cable of management of system cruise control.
7. Remove an inlet air branch pipe and a zabornik of fresh air.
8. Disconnect a vacuum hose from the vacuum amplifier of brakes.
9. Weaken a collar and remove the top hose of a radiator.

10. Disconnect a hose of supply of fuel from the fuel highway.
Prevention

Do not smoke and do not use an open flame about elements of fuel system as it can lead to explosion.
11. Weaken collars and disconnect hoses going to a heater.
12. Disconnect electric sockets from the valve of a control system of frequency of rotation of idling and the sensor of provision of a butterfly valve.
13. Disconnect electric sockets from fuel nozzles.
14. Disconnect from a head of the block of cylinders other electric sockets, remove an arm and reinstall an eye for an engine raising.

Inhaling moment: 37,2–51,9 N • m

15. Turn out a bolt and disconnect the grounding tire.
. 16. Turn out bolts and remove the thermofilter of a final collector.
17. Turn out bolts and remove a final collector from a head of the block of cylinders.
18. Turn out bolts and remove a bypass pipe for cooling liquid.
19. Turn out bolts and remove an arm of support of an inlet collector.
20. Remove hydraulic jacks of gaps of valves.
21. In a certain sequence, for 2–3 stages turn out bolts of fastening of a head of the block of cylinders.
22. Remove a head of the block of cylinders and laying of a head of the block of cylinders.

Check

PERFORMANCE ORDER
1. Check laying of a head of the block of cylinders on absence of leaks, spots from cooling liquid or прожогов laying between cylinders.
2. Clear interfaced surfaces of a head of the block of cylinders and the block of cylinders of the laying remains.
Prevention

Exclude hit of the remains of laying to canals for greasing and engine cylinders.
3. A metal ruler and shchupy in six directions check planeness of a head of the block of cylinders. If necessary, перешлифуйте head of the block of cylinders.

Maximum repolishing: 0,1 mm

4. If not planeness exceeds admissible limits, replace a head of the block of cylinders.
5. Measure height of a head of the block of cylinders.

Height:
TED: 133,9–134,1 mm
BFD: 133,8–134,0 mm

6. If the height of a head of the block of cylinders differs from nominal rates, replace a head of the block of cylinders.
Prevention

If it is necessary to make machining of a head of the block of cylinders, previously remove inlet and final collectors and check planeness of interfaced surfaces of collectors.
7. By a metal ruler and shchupy in two directions measure planeness of interfaced surfaces of collectors.

Deviation from planeness: no more than 0,20 mm

8. If not planeness exceeds admissible limits, replace a head of the block of cylinders.
9. A metal ruler and shchupy in six directions check planeness of an interfaced surface of the block of cylinders.

Deviation from planeness: 0,15 mm

10. If not planeness exceeds admissible limits, перешлифуйте the block of cylinders. The most admissible repolishing: 0,20 mm.

Installation

PERFORMANCE ORDER
1. Establish new laying on the block of cylinders of the engine. Establish a head of the block of cylinders.
2. Establish bolts of fastening of a head of the block of cylinders.
3. In a certain sequence tighten bolts of fastening of a head of the block of cylinders in some stages:
TED:
and. tighten bolts the moment of an inhaling of 49 N • m;
b. in sequence, return to a tightening, weaken bolts of fastening of a head of the block of cylinders;
c. repeatedly tighten bolts the moment of an inhaling of 39,2 N • m;
d. tighten bolts on 90 °;
е. tighten bolts on 90 °;

BFD: tighten bolts the moment of an inhaling of 76-81 N • m.
4. Establish hydraulic jacks of gaps of valves.
5. Establish an arm of support of an inlet collector and fix it bolts.

Inhaling moment:
TED: And – 15,7–22,5 N • m
In – 36,3–53,9 N • m
BFD: 31,4–46,1 N • m

6. Establish a bypass pipe for cooling liquid and fix it a bolt.

Inhaling moment: 89,2–116,6 N • m

7. Establish a final collector and fix it bolts.

Inhaling moment: 38–46 N • m

8. Establish the thermofilter of a final collector and fix it bolts.

Inhaling moment:
TED: 18,6–25,5
N • BFD m: 7,8–10,8 N • m
9. Connect the tire of grounding and fix it a bolt.
10. Establish an arm of electric sockets and repeatedly connect all sockets. Reinstall an eye for a raising of the engine and fix it bolts.

Inhaling moment: 37,2–51,9 N • m
11. Connect electric sockets to fuel nozzles.
12. Connect electric sockets to the valve of a control system of frequency of rotation of idling and to the sensor of provision of a butterfly valve.
13. Connect hoses going to a heater.
14. Connect a hose of supply of fuel to the fuel highway.
15. Connect the top hose of a radiator.
16. Connect a vacuum hose to the vacuum amplifier of brakes.
17. Establish to the place of an inlet air branch pipe and a zabornik of fresh air.
18. Establish a cable of an accelerator and check its sagging. If necessary, adjust sagging by rotation of a nut And.

Sagging: 1–3 mm
19. At existence, connect a cable of management of system cruise control.
20. Establish a hose of positive ventilation of a case and a ventilation hose.
21. Fill in in the engine engine oil.
