Removal and installation of the inlet pipeline and final collector

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

Inlet pipeline

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

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. On models with the D9B engine without turbo-supercharging remove an air distributor casing. In case of need remove also inlet air duct and disconnect a ventilating tube from a jellied mouth of motive 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). Release a cable from intermediate clamps and shift it aside where it will not prevent removal of a pipeline/collector.
4. On the models equipped with system of recirculation of the fulfilled gases (EGR) disconnect ventilating hoses from valves of a stream and recirculation. Release nuts and bolts of fastening of each of valves to the pipeline and to a collector remove valvate assembly from the engine. Remove sealing laying.
5. On models with a turbo-supercharging release fixing collars and disconnect air hoses from the air duct connecting a turbocompressor to an air cleaner branch pipe. Release an air branch pipe from the inlet pipeline and take it from a motive compartment. Zakuporte rags a turbocompressor 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 (Intercooler) from assembly of a turbocompressor.

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 the prutkovy key (A) and the central six-sided bolt (V) 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) Tighten all fixture with the required 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.

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 is not removed, perform the procedures described in the subsection "The Inlet Pipeline — Removal", subitem 1 — 4. On the models equipped with the EGR system perform also the procedure described in the subsection "The Inlet Pipeline — Removal", item 5.
3. On models without 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 turbocompressor remove assembly of the last (see Removal and installation of a turbocompressor).
5. On some models for the purpose of clearing of working space it is necessary to otboltit the rezonatorny camera from a collector.

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

7. Remove assembly of a collector 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 removal of a collector (to a zakontrita on the end of a hairpin 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 a layer of fresh sealant on the interfaced collector surface;
   b) The description of the procedure to the place of assembly of a turbocompressor (at the corresponding complete set) is provided in the section Removal and installation of a turbocompressor;
   c) The description of the 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 the required 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.
