5.7.7. 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 asbestos leaf reinforced by steel is established. At violation of tightness of this laying the engine works unevenly ("troit"). If it is not possible to eliminate malfunction with tightening of fastening of an inlet pipe, replace laying.

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

You will need a face or cap key "on 12".

1. Merge liquid from the cooling system (see. "Replacement of cooling liquid").

2. Weaken a tension of a belt of the drive of the generator and pump of the hydraulic booster of steering and take off a belt from a generator pulley (see. "Replacement of a belt of the drive of the generator and pump of the hydraulic booster of steering").

3. Turn out a bolt of fastening of a tension level of the generator and take away the generator from the engine, having turned it on an arm.	4. Weaken a collar of fastening of a hose of system of ventilation of a case of the engine to a branch pipe of a cover of a head of the block of cylinders, having squeezed passatizham its unbent ears, shift a collar on a hose …

5. … also disconnect a hose from a cover.	6. Turn off ten nuts and bolts of fastening of an inlet pipe in the sequence shown in fig. 5.5.

7. Remove an inlet pipe from hairpins, take slightly aside and remove laying from hairpins.	8. Carefully clear privalochny surfaces of a head of the block and an inlet pipe of the remains of old laying.

9. Establish new laying and all removed details in the sequence, the return to removal.

10. Tighten bolts and nuts of fastening of an inlet pipe in the sequence, return shown in fig. 5.5, the moment given in the appendix 1.

    

GOOD ADVICE In order to avoid sticking of laying and for increase in its tightness we recommend to grease before installation of laying it on both sides a thin layer of graphitic lubricant. Grease hairpins of a head of the block of cylinders and bolts of fastening of an inlet pipe with graphitic lubricant.
