10.3.4.3. Check and repair

The nozzle is non-demountable. At removal of a nozzle be careful, without allowing damage of the socket of electrical wires and a raspylitelny nozzle.

       NOTE
It is forbidden to clear and wash out a nozzle gasoline or other detergents.

Replace sealing laying of a nozzle new. In the presence of deposits on nozzle filters (big diameter — the filter of a purge, small diameter — the admission filter) blow them compressed air and wash out the fuel tank and fuel-supply lines.
At installation of a nozzle apply sealant on a carving of the screw of fastening of the holder.
Regulator fuel pressure. The spring under a cover of the regulator is in the compressed state therefore at a vyvertyvaniye of screws of fastening of a cover be careful.
After removal of the regulator check a condition of a nest of the valve, if necessary use magnifying glass. The nest should not have vykrashivaniye, dents and roughnesses of a surface. In the presence of any of these defects replace entirely the case of fuel feeding of the unit of the central injection.
The valve diaphragm after each dismantling is recommended to be replaced new. At assembly you apply sealant on a carving of screws of fastening of a cover of the regulator.

       NOTE
At installation of the regulator of pressure of fuel do not allow diaphragm distortions.

Case of fuel feeding of the unit of the central injection. At assembly of the unit of the central injection laying between cases of fuel feeding and a butterfly valve is recommended to be replaced new. Combine cuts in laying with openings in the case of a butterfly valve.
Apply sealant on a carving of screws of fastening of the case.
Sensor of provision of a butterfly valve. At installation of the sensor put a butterfly valve in a closed position and, turning the sensor counterclockwise, combine roller lysk with the sensor drive. Wrap fastening screws.

       NOTE
It is forbidden to clear and wash out the sensor of provision of a butterfly valve and the regulator of idling by gasoline or other detergents.

Idling regulator. Replace sealing laying new. The regulator has the conical valve with a diameter of 10 mm. If replacement is required, use the new valve of the corresponding model.
Before installation of the regulator check distance from a fastening flange to a trailer point of the valve of the regulator for the case of a butterfly valve. If the valve is too put forward, it can lead to damage of the regulator.
The distance has to be less than 23 mm. If at the new regulator it exceeds 23 mm, then it is possible a hand, shaking the valve here and there, to press it into the regulator.
At the regulator which was in operation it is not allowed to press the valve manually not to put the regulator out of action. For this purpose it is necessary to use the diagnostic unit or the special monitor.
After installation of the regulator of idling and the unit of the central injection connect the diagnostic unit to a diagnostic block and give the command to an electronic control unit on dumping of values of parameters of the regulator of idling.
Case of a butterfly valve. At assembly of the unit of the central injection of fuel sealing laying of the case of fuel feeding is recommended to be replaced new.
Clear the surfaces of the case of a butterfly valve and the case of vacuum branch pipes of material of old laying. Replace laying new.
