5.14.11. Removal and installation of throttle knot

Signs of not completely being closed butterfly valve can be the increased frequency of rotation of a cranked shaft idling and the increased fuel consumption. Signs of not completely opening butterfly valve — the engine does not develop the full capacity, insufficient acceleration performance of the engine, breakthroughs and failures in operation of the engine at car movement.

At these malfunctions at first try to adjust a drive of a butterfly valve or replace a cable (see. «Adjustment and replacement of a cable of a drive of a butterfly valve»). If it does not lead to positive result, replace throttle knot.

It be required to you: a face head «on 8», a screw-driver with a crosswise edge.

1. Disconnect a wire from the minus plug of the storage battery.

2. Disconnect blocks of a motor plait of wires from the sensor of provision of a butterfly valve...	3.... and from an idling regulator.

4. Disconnect from sector of throttle knot a cable of a drive of a butterfly valve (see. «Adjustment and replacement of a cable of a drive of a butterfly valve»).

5. Having weakened a fastening collar, disconnect airbringing sleeve from a branch pipe of throttle knot and take a sleeve aside (see. «Removal and installation of the air filter»).

6. Disconnect a hose of a purge of an adsorber from the union of throttle knot.	7. Turn out four bolts of fastening of throttle knot to a flange of the inlet pipeline...

8.... also remove throttle knot.

Note Pay attention to that connection of throttle knot and the inlet pipeline is condensed with laying. Strongly pressed out or torn laying replace.

9. If at replacement of throttle knot on new knot the sensor of 1 provision of a butterfly valve and a regulator 2 idlings are not established, rearrange them from the removed knot, having turned out on two screws of their fastening.

10. If throttle knot removed not for replacement, clear the polluted throttle knot liquid for cleaning of carburetors, previously having removed from it the sensor and a regulator. Clear also polluted regulator and the sensor (it is forbidden to use solvents for cleaning).

11. Remove from a cavity of the inlet pipeline oil and other pollution.

12. Establish throttle knot and all removed details as it should be, the return to removal.

13. Adjust a butterfly valve drive (see. «Adjustment and replacement of a cable of a drive of a butterfly valve»).
