5.8.7. Replacement of laying of an inlet pipe

Between flanges of a head of the block of cylinders and an inlet pipe the sealing laying made of the pressed asbestine leaf, reinforced by steel is established. At violation of tightness of this laying the engine works roughly («троит»). If it is not possible to eliminate malfunction a tightening of fastening of an inlet pipe, replace laying.

For replacement of laying of an inlet pipe to disconnect any hoses (except a hose of system of ventilation of a case of the engine) and wires it is not required. Their flexibility allows to take away an inlet pipe from a head of the block of cylinders on distance, sufficient for laying removal.

It be required to you: a face head «on 13», пассатижи, a screw-driver with a crosswise edge.

1. Disconnect a cable tip from sector of a drive of a butterfly valve, take a cable braid from an arm and take a cable aside (see. «Adjustment and replacement of a cable of a drive of a butterfly valve»).	2. Disconnect a block of a plait of wires from conclusions of the sensor of provision of a butterfly valve...

3.... from conclusions of a regulator of idling...	4.... from conclusions of the sensor of absolute pressure in an inlet pipe...

5.... and from conclusions of nozzles of system of injection of fuel.	6. Disconnect a block of a plait of wires from conclusions of the sensor of phases of the gas-distributing mechanism...

7.... also take plaits of wires aside.	8. Separate the plastic collar connecting a fuel stage and directing masloizmeritelny щупа.

9. Weaken an inhaling of a collar and disconnect airbringing hose from a branch pipe of throttle knot.

10. Remove a fuel stage and, without disconnecting from it a hose in order to avoid system depressurization, take a stage aside (see. «Removal and installations of a fuel stage»).

11. Remove throttle knot (see. «Removal and installation of throttle knot»).

12. Weaken a collar of fastening of a vacuum hose to a receiver, having compressed its unbent ears, shift a collar on a hose...	13.... also disconnect a hose from a receiver.

14. Weaken a collar inhaling...	15.... also disconnect from a receiver branch pipe a hose of ventilation of a case.

16. Turn out two bolts of fastening of a supporting arm to an inlet pipe and one bolt of fastening to the block of cylinders.	17. Turn out two bolts of fastening of the amplifier to a receiver...

18.... one nut of fastening of the amplifier and an inlet pipe to a head of the block of cylinders...	19.... also remove the amplifier.

20. Unscrew nuts of fastening of an inlet pipe to a head of the block of the cylinder.

Note Places of fastening of an inlet pipe are so located.

21.... also remove an inlet pipe assembled with a receiver.	22. Remove old laying.

23. Remove the remains of old laying from privalochny surfaces of an inlet pipe and a head of the block of the cylinder.

24. Turn out two bolts 1 and three nuts 2...	25.... also separate a receiver and an inlet pipe.

26. Remove old laying from receiver hairpins.

27. Remove the remains of old laying from privalochny surfaces of an inlet pipe and a receiver.

28. Establish new laying and all removed details as it should be, the return to removal.
