3.2.13.5. Repair of a head of the block of cylinders
THE GENERAL DATA

Place of measurement of height of a head of the block of cylinders and sign перешлифованной heads

 

 

h – height of a head of the block of cylinders,
And – a sign arrangement перешлифованной heads
R – a sign перешлифованной heads

The sizes of directing plugs of valves

f, g, h, k, j – subsection 3.2.1 see

The sizes of saddles of valves

a, b, c, d – subsection 3.2.1 see

Comparison of nests of valves on early and late models

And – old type,
b – new type,
1 – nests of valves

PERFORMANCE ORDER
1. Remove a head of the block of cylinders.
2. Gradually release fastening of covers of bearings of a camshaft.
3. Remove covers of bearings, designating a direction of their fastening.
4. Remove the sealing ring which is on the end of a camshaft.
5. Remove a camshaft.
6. Designate and remove pushers of valves.
7. By means of a special clip take the valve together with their springs and arrange them one after another.
8. Take vortical chambers, beating out them through an aperture for atomizers.
9. Clear a head of the block of cylinders. It is necessary to apply a special cleaner to clearing of a surface of connection "Decaploc 88".
10. Check up planeness of a surface of connection with the block of cylinders of the engine (maximum неплоскостность 0,07 mm).
11. In case of need follows перешлифовать a head of the block of cylinders. For this purpose it is necessary to execute following actions:
      – перешлифовать nests of valves so that to receive a necessary course;
      – To replace vortical chambers with vortical chambers of the repair sizes and to achieve their necessary value выступания;
      – Under springs of valves establish compensating linings in the thickness of 0,4 mm.
12. Check up a condition of directing plugs of valves. In case of need it is necessary to replace them. It is necessary to charge performance of this operation to the qualified expert. Replacement of directing plugs of valves demands obligatory repolishing or replacement of corresponding saddles of valves.
13. Check up a condition of saddles of valves. In case of need them follows перешлифовать or to replace. It is necessary to charge performance of this operation to the qualified expert.
14. Check up a condition of springs and a camshaft.
15. Check up выступание vortical chambers (0–0,03 mm).
16. In case of need it is necessary to achieve the necessary size processing of surfaces "х" and from"vortical chambers (Comparison of nests of valves fig. see early and late models).
17. Check up facets of valves.
18. In case of need it is necessary to achieve the necessary sizes polishing of saddles of valves.
19. Grind in valves.
20. Establish valves.
The prevention

If the head of the block of cylinders was перешлифована it is necessary to establish under springs of valves compensating linings in the thickness of 0,4 mm.


21. Establish on rods of valves of a plate in the thickness of 2,425 mm and check up, whether exceed plates of a plate of springs.
22. If plates do not exceed plates of springs follows сошлифовать the top surfaces of plates.
23. Establish pushers.
24. Oil camshaft bearings.
25. Establish a camshaft a sign "DIST" to a drive timing.
26. Establish covers of bearings and gradually tighten them till the moment of 17,5 Nanometers.

27. Establish a head of the block of cylinders.
