THE GENERAL DATA

Exhaust system, arrangement of components (4-cylinder models)


1. A tube for measurement WITH
2. A cap of a tube for measurement WITH
3. 25 Н.м.
4. A final collector
5. 30 Н.м.
6. Consolidation
Always replace
7. 35 Н.м.
8. 40 Н.м.
9. The average muffler
Average and back mufflers are established at factory as a uniform detail, spare average and back mufflers are delivered separately together with tightening муфтой
10. A fixing ring
Preliminary tightness: approximately 7мм
Pay attention to arrows in вкладке And
11. Depth of introduction "and" should be at least 42.5 mm
12. Tightening муфта
13. 40 Н.м.
14. Fixing rings
Preliminary tightness: about 12 mm
15. The back muffler
16. A place of a cut for replacement
It is marked by cuts (3) on a circle of a connecting pipe
Cut a pipe at right angle to a pipe axis
In the established position the cut can be made a chain saw
The cut can be made also, having removed system
To remove an exhaust system, ослабьте a clip ahead of the average muffler and fastening of the left bottom shock-absorber, also lower a back axis
17. Tightening муфта
18. 40 Н.м.
19. The Katalitichesky converter
20. A tube for measurement WITH
21. The oxygen gauge (50 Н.м.)
Cover a carving with structure G5
Do not allow G5 to get to cuts on the gauge case
22. A basic arm
It is attached to transmission
23. 25 Н.м.
24. An exhaust pipe

The prevention

After work over an exhaust system check up, that in connections there was no preliminary tightness and there was a sufficient interval between system and a body. If necessary ослабьте fixing clips also adjust position of the muffler and an exhaust pipe, turning and moving them in a longitudinal direction to receive a sufficient interval and in regular intervals to load fixing rings.

Always replace all самоконтрящиеся nuts.

The prevention

The carving of the oxygen gauge is covered противозадирочным by structure. Do not allow structure to get to gauge cuts.

After work over an exhaust system check up, that in connections there was no preliminary tightness and there was a sufficient interval between system and a body. If necessary ослабьте fixing clips also adjust position of the muffler and an exhaust pipe, turning and moving them in a longitudinal direction to receive a sufficient interval and in regular intervals to load fixing rings.

Always replace all самоконтрящиеся nuts.
