Dismantling of a head of cylinders

 PERFORMANCE ORDER

The new or restored head of cylinders can always be ordered in a workshop of car service or in a warehouse company service center 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, authors of this manual consider, than to be got involved what to the amateur mechanic more simply and cheaper will be to get a replaceable head in rather complex recovery repair of worn-out.

Right after removal of a head take an oil dispersion jet(s) from the engine block, clean it and put in a separate plastic bag.

1. Dismantling of a head of cylinders demands preliminary dismantle of the valvate mechanism (inlet and final valves with the accompanying components). It is meant that yokes and the camshaft(s) are already taken from a head.

2. By means of the special tool squeeze springs of the first valve and take from a flute on a core crackers of the cutting lock of a plate. Carefully release the tool and remove from the valve a plate of springs, springs and their saddle (depending on a complete set).

3. Put the removed components of valvate assemblies in accurately numbered separate plastic bag.

4. Further, take the valve from a head of cylinders and remove a maslootrazhatelny cap from the directing plug. If there is a jamming of the valve in the directing plug, push it back in a head and an oselok or a file with small tooth accurately smooth out edges of a flute under installation of crackers.

5. Working in a similar manner, remove the remained valvate assemblies. Put the removed components of each of valves in the separate, equipped with the corresponding label package, - at assembly each detail has to be established strictly on the former place.
6. After all components of the valvate mechanism are taken and put in an organized order, it is possible to start performing procedures of cleaning and check of a condition of a head (at full-scale recovery repair of the engine before finish its dismantling).
