5.4.19. The idling valve (КХХ)
THE GENERAL DATA

The idling valve

AND. DISTANCE FROM END ЗАПОРНОГО OF THE ELEMENT TO THE INTERFACED PLANE OF THE FLANGE
CENTURY DIAMETER ЗАПОРНОГО THE ELEMENT
WITH. THE SEALING RING
D. THE FIXING SCREW

To remove or disconnect

PERFORMANCE ORDER
1. Electric socket КХХ.
2. To turn out fixing screws.
3. The valve.
The prevention

It is necessary to address cautiously with КХХ. It is forbidden to press or extend from the valve запорный an element. It can lead to damage of screw gear КХХ. In order to avoid failure the valve should not contact to any solvents or cleaners.



To clear and check up

PERFORMANCE ORDER
1. To clear a landing nest of a sealing ring, a saddle of the valve and the air channel.
For removal of adjournment it is necessary to use a cleaner for carburettors and a brush.
Presence of brilliant stains on запорном an element or saddle КХХ is the normal phenomenon and does not testify to infringement соосности or deformations запорного an element.
If the air channel is strongly polluted by adjournment, it is necessary to dismantle the case throttle заслонки for careful clearing of the channel.
2. To check up a condition of a sealing ring, presence of cuts, cracks or deformations. To replace a defective ring.

To measure (at installation new КХХ)

PERFORMANCE ORDER
Distance from the end запорного an element to an interfaced plane of a flange.
If this distance exceeds 28 mm, it is necessary to press a finger and slowly to drown запорный an element in the valve case. The effort necessary for moving запорного of an element of the new valve, cannot cause damage of the mechanism of the valve. This updating of position запорного an element excludes possibility of its emphasis in a saddle at installation КХХ. The distance of 28 mm corresponds to position запорного an element idling at repeated start-up of the engine.

To establish or attach

PERFORMANCE ORDER
1. To grease with engine oil sealing ring КХХ.
2. The idling valve.
3. To screw fixing screws. To tighten fixing screws KHH the moment of 3 Nanometers.
4. An electric socket.
5. To expose into position запорный element КХХ.
5а. To include ignition, without starting the Engine.
5б. To connect to "weight" the plug of a diagnostic socket for 5 seconds.
5в. To disconnect the plug from "weight".
5г. To switch off ignition for 10 seconds.
5д. To start the Engine and to check up idling.
