Remove external covers газораспределительного a belt and a pulley of a cranked shaft (Sections Reduction of the piston of the first cylinder in position of the top dead point (ВМТ) the end of a step of compression see, Removal and installation of a belt of drive ГРМ and its covers). Remove газораспределительный a belt from a camshaft cogwheel.
13. After removal газораспределительного a belt the engine can be lifted back in a starting position, and the right support of the unit is connected.
14. In order to avoid casual contact of pistons with valves in the course of head removal, composers of the present Management recommend to develop a cranked shaft back in position on some degrees before ВМТ.
15. Remove a plate of the device of heating of soaked up air from the top part of a final collector.

... Disconnect from a collector a reception pipe of system of release of the fulfilled gases. Remove a lining.

16. Turn out a bolt of fastening of a directing tube probeа measurements of level of impellent oil to a back part of a head of cylinders. At a corresponding complete set отболтите also remove a basic arm of the inlet pipeline.
17. Disconnect a gas cable (the Power supply system see the Head).
18. Uncover heads of cylinders (see Has undressed Removal and installation of a cover of a head of cylinders).

19. Operating in an order specified in illustrations...

... In stages (on a half-turn for the approach) ослабьте bolts of fastening of a head so that there was a reversing possibility their hands.

20. Make sure that to a head of cylinders there were connected no lines of communication. Remove a head from the block of cylinders (in case of need take advantage of the help of the assistant, in particular if the head acts in film in gathering with the pipeline and a collector).
21. Remove a lining from a surface of the block interfaced to a head. Do not throw out it, having kept as a template.
22. If performance of major repairs of a head is supposed.
Branch from a head of the inlet pipeline and a final collector
23. The description of procedures of removal and installation of the inlet pipeline is resulted to the Head the Power supply system.
24. In stages give the remained fixing nuts (at nut assemblage are subject to replacement without fail) and remove from a head of cylinders a final collector with linings.
25. Carefully smooth out interfaced surfaces, lay new linings, then establish a final collector. Screw new fixing nuts and tighten them with demanded effort.

PREPARATION FOR ASSEMBLAGE

 PERFORMANCE ORDER

1. By means of the scraper made of a soft material carefully smooth out interfaced surfaces of a head and the block. Remove from surfaces all traces of a material of an old lining and coal adjournment. Smooth out also the bottoms of pistons. Try not to admit dust hit in water galleries and маслостоки (coal particles are capable to block tightly oil giving to internal components of the engine) - close up all accessible apertures with an adhesive tape. Between walls of pistons and cylinders in the same purposes it is necessary to fill backlashes консистентной with greasing which then will be easy for removing by means of a thin brush.
2. Check up interfaced surfaces of the block and a head of cylinders on presence of scratches, задиров and other mechanical damages. Insignificant defects can be removed by means of a file with a small tooth. In case of more serious damages it is necessary to resort to станочной to machining.
3. Estimate planeness of interfaced surfaces by means of a special template (an edge of a steel ruler) and probeа лезвийного type.
4. Check up a condition of bolts of fastening of a head, special attention giving to their carving part. Wash out boats in solvent, then carefully dry. Defective bolts are subject to replacement. Measure length of each of fixing bolts for the purpose of revealing of their signs вытягивания (the given check it is impossible to consider unequivocal as all bolts can appear are extended for identical length). Composers of the present Management recommend to make replacement of bolts of fastening of a head without dependence from their condition.

5. Banish болтовые apertures in the block of cylinders a suitable tap, cleaning a carving and restoring the damaged coils.

At absence of near at hand suitable tap of an aperture can be cleaned by means of the self-made adaptation made of a long hairpin with a carving sawn through lengthways.

6. In order to avoid damage of pistons and valves composers of the present Management recommend to take away before head installation a cranked shaft on 90 back from position ВМТ (in case of need address to materials Has undressed the Description of the basic knots and mechanisms).
