Repair Sharan/Sharan Volkswagen>> VR6 engine>> System of production of the fulfilled gases>> Removal and installation of system of production of the fulfilled gases
Service life of system of production of the fulfilled gases as a whole depends on conditions in which the car is maintained. At frequent trips on small distances there is a significant amount of condensate and aggressive acids in the exhaust silencer that leads to corrosion of system of an exhaust from within. Trips at working temperature and favorable conditions of combustion of a working mix reduce the content of substances by big distances causing corrosion in the fulfilled gases. Besides, thus there is a combustion of the foreign matters which have got in an exhaust system thanks to high temperature.
Corrosion of system of an exhaust outside is caused by hit on it of water and salt. It can be promoted by blows of stones. The free engine mount leads to fluctuations of the engine which are transferred to junctions of reception pipes and all remained exhaust system.
The system of production of the fulfilled gases should be checked at each opportunity in time to notice possible damages, to prevent or eliminate them. For this purpose make the following:
- check, whether carving connections on an inlet collector and in fastening places are weakened, and do not tighten them with excessive effort;
Fig. 102. Elements of a back part of system of production of the fulfilled gases: 1 — goes from the catalyst (an arrow 3 see fig. 101); 2 — a fastening collar; 3 — a nut, 40 N · m; 4 — the suspension bracket ring, indicates the correct situation at installation; 5 — a nut of the screen of thermal protection; 6 — the screen of thermal protection; 7 — the forward exhaust silencer; 8 — the back exhaust silencer; 9 — b distance = 50 mm; 10 — a distance = 5 mm





- check rubber rings 4 (fig. 102) of a suspension bracket on fragility, cracks and other damages and if necessary replace them;
- at the working engine stop up the end of an exhaust pipe with a rag. If the engine decays after a while, the system of production of the fulfilled gases is tight. If the hissing sound is audible, the system of production of the fulfilled gases is not tight;
- if the system of production of the fulfilled gases sounds deafly, shortly it is necessary to change the exhaust silencer.
Installation of the catalyst does not represent any difficulties, however thus observe the following recommendations:
- twirl connection of a final collector (see item 2.10.2);
- fix thermal protection of the engine by means of tightening washers;
- replace the damaged rubber rings of a suspension bracket of system of production of the fulfilled gases;
- always change laying between a reception pipe and the catalyst;
- before tightening fastening collars properly connect pipes. Tighten nuts the every moment of an inhaling;
- at in, if it was unscrewed, put on its carving G5 lubricant. Track that lubricant did not get to shlitsa of the case a lambda probe as in this case the probe can incorrectly work;
- at replacement of details of system of production of the fulfilled gases it is necessary to pay special attention to an and b gaps (see fig. 102 ). The distance and between openings for a suspension bracket should be at least 5 mm. It belongs to forward and back exhaust silencers. The distance of b should make at least 50 mm, i.e. the fixing clip should be shifted on a junction of pipes before it will be tightened;
- always use new nuts, 40 N · m.
