4.18. Assembly of a head of cylindersRegardless of that, the head went to a workshop for carrying out service of valves, or not, before starting its assembly, once again carefully check purity of all components.
After head return from a workshop in it valves with accompanying components will be already established. In this case it is necessary to lower corresponding of listed below procedures and at once to pass to installation of shaft and assemblies of yokes.
|
|
- First of all establish on directing plugs of valves of a saddle of their springs, then put on each of directing plugs a new maslootrazhatelny cap (see. Dismantling and check of a condition of a head of cylinders and components of the klapanny mechanism). Maslootrazhatelnye caps (inlet and final valves) "are put" on the directing plugs by a careful zastukivaniye by a hammer through a special opravka or a face head of the suitable size.
|
|
Stop a cap zastukivaniye right after that as it completely "will sit down" on the plug - further blows can lead to rubber damage. Track, that caps did not appear are overwound on plugs. |
- Moving from one end of a head to another, grease with molibdensoderzhashchy or assembly impellent greasing the first valve and plant it in a head. A core of the valve grease with pure impellent oil.
- By means of a noniusny calliper serially check adjusting height of cores of each of valves (distance from a saddle of springs to a face surface of a core of the valve) (see. Dismantling and check of a condition of a head of cylinders and components of the klapanny mechanism).
|
|
If repair of a head was made in a car-care center workshop, this parameter already will be adjusted properly. If the result any of measurements exceeds admissible value according to Specifications, replace the corresponding valve and repeat check. If replacement of the valve does not lead to situation correction, therefore, the valve saddle too deeply is planted in a head and the last is subject to replacement. |
- Plant on a core klapanny springs and their plate.
|
|
Springs are established to Klapannye by rounds with the truncated step to a head. |
|
- The special tool compress springs, having lowered a plate, then plant in the opened flute on a valve core crackers of the cutting lock.
|
|
- For the purpose of temporary fixing of crackers to an otpuskaniye of the tool grease them from the inside with dense greasing.
|
|
- Repeat procedure for the remained valves. Watch that all components were established strictly on the former places.
- Camshaft installation (ов) and assemblies of yokes is made after the head will be completed in the reduced set (see. Alternative versions of schemes of regenerative repair of the engine).
