Dismantling of a head of cylinders
|
The new or restored head of cylinders can always be ordered in a workshop of car service or in a warehouse firm 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 that to the amateur mechanic more simply and cheaper will be to get a replaceable head, than to be got involved in rather difficult recovery repair of the worn-out. |
|
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 pushers and camshafts are already taken from a head (see Part Repair of the engine without extraction from the car - the Civic model of the present Chapter).
|
2. Before starting removal of valvate assemblies, prepare necessary quantity of appropriately marked plastic bags for folding in them the removed components (see an accompanying illustration). |
|
3. 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 (see an accompanying illustration). Carefully release the tool and remove from the valve a plate of springs, springs and their saddle (depending on a complete set). |
|
On the Integra models valvate springs are drowned and their tightening will require a special nozzle to the standard tool. |
|
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 polyethylene – 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 performance of procedures of cleaning and check of a condition of a head (at full-scale recovery repair of the engine before finish its dismantling). |
