9.10. Councils for work with an exhaust system
|
|
Lift the car, establish horizontally and fix, that he did not fluctuate.
If it is impossible to release the rusted screw connections, try to overwind nuts – more often screws after that it is possible to break. For installation use only new screws, spring rings, nuts and linings.
With a view of safety replace also all fixing rubber.
If the exhaust system already was exposed earlier to partial repair separate connections of the ends of pipes is better in нагретом a condition. In workshops the welding torch – as a rule, the good tool and for homeworks is for this purpose used. Thus necessarily protect the hands and eyes by means of working gloves and points. Besides hold nearby the fire extinguisher.
Practical advice: before including a torch, try in the beginning happiness with the means dissolving a rust.
Separate tubes and flanges further strong rotary motions, support their easy blows of a hammer.
If it does not help, chop off or cut off connection approximately on 10 centimetres from a junction. The pipe rest further saw off to a division place in a longitudinal direction and raise a strong screw-driver.
Subsequently screw connections of final system will be easier for releasing, if before installation the carving is greased by heat resisting copper greasing. This remark can be carried and to blocked trumpet connections.

Do not trust small pendant loops – look after at exhaust system check
From outside the engine the exhaust system is screwed strongly together with a final collector. Under the bottom of the car it is freely suspended by means of rubber loops. If your exhaust system starts "to hoot and ring" or even to concern earth, any more do not trust welded seams, mufflers and pendant loops. Check up "rusty" places, thus be not frightened to use for this purpose and blows by a hammer.

Check up rubber loops on rupture, presence of cracks and other damages and if necessary replace. For check shake a trailer tube of release strongly there-here.
Check up on collector flanges all connections on durability of landing.
Start the engine and insert into a trailer tube a rag. Already after a while the engine should stop. If you hear hissing sounds or the engine continues to work, the system is not tight.
Strong noise of combustion and clap in a mode of compulsory idling unmistakably specify in presence of defects in an exhaust system.
Knock slightly with a hammer on all surface of mufflers and tubes. Do not forget also forward walls of mufflers – thus strike not so shy. If the metal sheet "is healthy", your blows sound "chilly and accurately", you learn rotted through metal on the muffled sounds.

It is better to replace completely: Rubber loops (are specified by an arrow) after performance of works with an exhaust system. |
