5.4.19. Valve of idling (KHH)

GENERAL INFORMATION

Idling valve

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

To remove or disconnect

PERFORMANCE ORDER
1. KHH electric socket.
2. To turn out fixing screws.
3. Valve.
Prevention

It is necessary to address carefully with KHH. It is forbidden to press or extend a locking element from the valve. It can lead to damage of a screw gear of KHH. In order to avoid failure the valve should not contact to any solvents or cleaners.



To clear and check

PERFORMANCE ORDER
1. To clear a landing nest of a sealing ring, a saddle of the valve and the air channel.
For removal of deposits it is necessary to use a cleaner for carburetors and a brush.
Existence of brilliant spots on a locking element or a saddle of KHH is the normal phenomenon and does not testify to violation of coaxiality or deformation of a locking element.
If the air channel is strongly polluted by deposits, it is necessary to dismantle the butterfly valve case for careful cleaning of the channel.
2. To check a condition of a sealing ring, existence of cuts, cracks or deformations. To replace a defective ring.

To measure (at installation of new KHH)

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

To establish or attach

PERFORMANCE ORDER
1. To grease with engine oil a sealing ring of KHH.
2. Idling valve.
3. To screw fixing screws. To tighten the KHH fixing screws the moment of 3 Nanometers.
4. Electric socket.
5. To expose into position the KHH locking element.
5а. To include ignition, without starting the Engine.
5б. To connect to "weight" the plug of the 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 idling.
