Removal and installation of the inlet pipeline and final collector

On the models equipped with a turbokompressor, assemblies of the inlet pipeline and a final collector are established on one sealing laying in view of what their dismantle is more reasonable for making together with the purpose of simultaneous replacement of laying.

Inlet pipeline

At assembly do not forget to make replacement of sealing laying (ok).

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. On models with the D9B engine without a turbo-supercharging remove an air distributor casing. In case of need remove also inlet air line and disconnect a ventilating tube from a jellied mouth of impellent oil (see appropriate sections of the present Chapter).
3. Disconnect a gas cable from TNVD (see. Removal, installation and adjustment of a cable of gas). Liberate a cable from intermediate clamps and shift it aside where it will not disturb pipeline/collector removal.
4. On the models equipped with system of a retsirkulyatsiya of fulfilled gases (EGR), disconnect ventilating hoses from stream and retsirkulyatsiya valves. Release nuts and bolts of fastening of each of valves to the pipeline and a collector remove klapanny assembly from the engine. Remove sealing laying.
5. On models with a turbo-supercharging release fixing collars and disconnect air hoses from an air line connecting a turbokompressor to a branch pipe of an air purifier. Liberate an air branch pipe from the inlet pipeline and take it from an impellent compartment. To Zakuporta rags a turbokompressor hose, or an opening actually in assembly of the last if the hose is completely removed. Release a fixing collar and disconnect an air hose of the built-in cooler (Intercoоler) from turbokompressor assembly.

6. By means of a suitable prutkovy key turn out bolts of fastening of the inlet pipeline; weaken, but do not turn out (the pipeline is dismembered), the central six-sided bolt.
Bolts of fastening of the pipeline (with a head under a prutkovy key (And) and the central six-sided bolt (In), used on models with a turbo-supercharging, - it should be weakened only); the engine is for descriptive reasons removed from the car

7. Remove the pipeline from a head of cylinders.

Installation

Installation is made upside-down. Pay attention to the next moments:
   a) Do not forget to replace sealing laying (and);
   b) All fixture tighten with demanded effort;
   c) After connection of a cable of gas, make its adjustment (see. Removal, installation and adjustment of a cable of gas);
   d) Track correctness of connection and reliability of fastening of all hoses and tubes.

Final collector

At assembly do not forget to make replacement of sealing laying (ok).

Removal

 PERFORMANCE ORDER

1. For the purpose of ensuring access (especially on models with a turbo-supercharging) remove the inlet pipeline (see the previous subsection).
2. If the inlet pipeline does not act in film, execute the procedures described in subsection "The inlet pipeline - Removal", subitem 1 — 4. On the models equipped with EGR system, execute also the procedure described in subsection "The inlet pipeline - Removal", item 5.
3. On models without a turbo-supercharging disconnect from a final collector a reception pipe of system of production of the fulfilled gases (see. Systems of decrease in toxicity and production of the fulfilled gases).
4. On the models equipped with a turbokompressor, remove assembly of the last (see. Removal and turbokompressor installation).
5. On some models for the purpose of clearing of working space it is necessary отболтить from a collector the rezonatorny chamber.

6. Give six nuts of fastening of a final collector and remove from hairpins remote plugs.

7. Remove collector assembly from a head of cylinders; also remove sealing laying (and).

8. Sometimes fixing hairpins are turned out together with nuts. In such cases they should be screwed back in a head right after collector removal (законтрите on the hairpin end two nuts and use them as a bolt head).

Installation

Installation is made upside-down. Pay attention to the next moments:
   a) Do not forget to replace sealing laying (and). If laying is not provided, put on an interfaced surface of a collector a layer of fresh hermetic;
   b) The procedure description to the place of turbokompressor assembly (at the corresponding complete set) is provided in the section Removal and turbokompressor installation;
   c) The description of procedure of connection to a collector of a reception pipe of system of production of the fulfilled gases is provided in the section of System of decrease in toxicity and production of the fulfilled gases;
   d) All fixture should be tightened with demanded effort;
   e) After connection of a cable of gas make its adjustment (see. Removal, installation and adjustment of a cable of gas);
   f) Track correctness of connection and reliability of fastening of all hoses.
