Replacement of details and the knots established in the case of a butterfly valve, is made without dismantle from the engine of the case of a zaslonka. However for case replacement assembled it is necessary to remove it from the car.

To clear

PERFORMANCE ORDER

Deposits on walls of an air line and on a butterfly valve are removed by means of a cleaner for carburetors and a piece of a protirochny fabric 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 deposits in the butterfly valve case. Metal details can be cleared after dismantling by an immersion and keeping way in solvent.

Prevention

The sensor of provision of a butterfly valve and the valve of idling should not contact to solvents or cleaners as it will lead to damage of knots.

To remove or disconnect

PERFORMANCE ORDER

1. Negative wire of the battery.

2. Partially to merge cooling liquid from a radiator to disconnect hoses from the butterfly valve case.

3. Vacuum hoses from the butterfly valve case.

4. DDH and KHH electric sockets.

5. An air branch pipe of an air purifier from the zaslonka case.

6. Hoses of a supply and removal of cooling liquid from the butterfly valve case.

7. A butterfly valve drive from a pedal of an accelerator and the actuation mechanism cruise control.

8. To turn out bolts of fastening of the case of a butterfly valve.

9. The zaslonka case together with laying. Laying to throw out.

10. To clear details.

Prevention

When cleaning the interfaced planes of details of the remains of a material of laying it is necessary to show care.

To establish or attach

PERFORMANCE ORDER

1. The butterfly valve case with new laying.

2. To screw fixing bolts. To tighten fixing bolts of the case of a zaslonka.

3. A butterfly valve drive from a pedal of an accelerator and the actuation mechanism cruise control.

Prevention

It is necessary to be convinced that butterfly valve drives from a pedal of an accelerator and the actuation mechanism cruise control allow a zaslonka to be closed completely.

4. Hoses of cooling liquid to the butterfly valve case.

5. An air branch pipe of an air purifier to the zaslonka case.

6. DPH and KHH electric sockets.

7. Vacuum hoses to the butterfly valve case.

8. To add cooling liquid in a radiator.

9. Negative wire of the battery.

To check

PERFORMANCE ORDER

At the idle engine completely to press and release an accelerator pedal for check of freedom of movings of a butterfly valve.

Prevention

After installation on the Engine of the case of a butterfly valve of any adjustments of KHH it is not required. Calibration of provision of the KHH locking element is made by EBU in an automatic mode after car dispersal till the speed exceeding 48 km/h.
