THE GENERAL DATA

The case throttle заслонки

 

1. THE LINING
10. THE CASE THROTTLE ЗАСЛОНКИ
13. THE PROTECTIVE CAP OF THE RESTRICTIVE SCREW OF IDLING
16. RESTRICTIVE BANDAGE OF IDLING
17. THE SPRING OF THE RESTRICTIVE SCREW OF IDLING
20. THE GAUGE OF POSITION THROTTLE ЗАСЛОНКИ
21. THE SCREW OF FASTENING ДДЗ
70. THE IDLING VALVE
72. THE SEALING RING
73. BANDAGE OF FASTENING КХХ

Replacement of details and the knots established in the case throttle заслонки, is made without dismantle from the engine of the case заслонки. However for case replacement in gathering it is necessary to remove it from the car.

To clear

PERFORMANCE ORDER
Adjournment on walls of an air line and on throttle заслонке leave by means of a cleaner for carburettors and a piece протирочной fabrics It is forbidden to use the cleaners including methyl or ethyl connections. Similar cleaners are very aggressive and are not necessary for removal of rather easy adjournment in the case throttle заслонки. Metal details can be cleared after dismantling by immersing and keeping in solvent.
The prevention

The gauge of position throttle заслонки and the idling valve should not contact to solvents or cleaners as it will lead to damage of knots.



To remove or disconnect

PERFORMANCE ORDER
1. A negative wire of the battery.
2. Partially to merge cooling liquid from a radiator to disconnect hoses from the case throttle заслонки.
3. Vacuum hoses from the case throttle заслонки.
4. Electric sockets ДДХ and КХХ.
5. An air branch pipe of an air cleaner from the case заслонки.
6. Hoses of a supply and tap of a cooling liquid from the case throttle заслонки.
7. A drive throttle заслонки from a pedal of an accelerator and a cruise-control actuation mechanism.
8. To turn out bolts of fastening of the case throttle заслонки.
9. The case заслонки together with a lining. A lining to throw out.
10. To clear details.
The prevention

At clearing of interfaced planes of details of the rests of a material of a lining it is necessary to show care.



To establish or attach

PERFORMANCE ORDER
1. The case throttle заслонки with a new lining.
2. To screw fixing bolts. To tighten fixing bolts of the case заслонки.
3. A drive throttle заслонки from a pedal of an accelerator and a cruise-control actuation mechanism.
The prevention

It is necessary to be convinced that drives throttle заслонки from a pedal of an accelerator and a cruise-control actuation mechanism allow заслонке to be closed completely.


4. Hoses of a cooling liquid to the case throttle заслонки.
5. An air branch pipe of an air cleaner to the case заслонки.
6. Electric sockets ДПХ and КХХ.
7. Vacuum hoses to the case throttle заслонки.
8. To add cooling liquid in a radiator.
9. A negative wire of the battery.

To check up

PERFORMANCE ORDER
At the idle engine completely to press and release a pedal of an accelerator for check of freedom of movings throttle заслонки.
The prevention

After installation on the Engine of the case throttle заслонки any adjustments КХХ it is not required. Position calibration запорного element КХХ is made ECU in an automatic mode after dispersal of the car till the speed exceeding 48 km/h.
