Dismantle of a head of cylinders

The new or restored head of cylinders always can be ordered in a workshop of car-care center or in warehouses service centers of the company manufacturer of the car. In view of need of use during dismantling and check of a condition of a head of some special tools, originators of the real Management consider that to the amateur mechanic more simply and will cheaper get a replaceable head, than to be got involved in rather difficult and labor-intensive process of recovery operations.

2. If still made it, remove the inlet pipeline and a final collector (see appropriate section of Head of the Power supply system and release).
3. Take from a head a camshaft and pushers with adjusting washers (see. The repair procedures which are not demanding extraction of the engine from the car - petrol engines or the Repair procedures which are not demanding extraction of the engine from the car - diesel engines).
4. On diesel engines turn out from a glow plug head (see. Preheat system - diesel models) and nozzles (see. A power supply system - diesel models).

5. On all engines by means of the special tool compress a spring of the first of valves.

8. Further, by means of flat-nose pliers accurately remove from the directing plug a maslootrazhatelny cap. Operating in a similar manner, take components of the remained valves.

9. If after a spring szhimaniye its plate does not manage to be shifted for the purpose of ensuring access to crackers of the cutting lock, slightly обстучите the top part of an opravka of the adaptation a hammer, is should help plate release.
10. Having pushed valves inside also take from via combustion chambers.
