Prevention

Survey and repair of an exhaust system is carried out only after complete cooling of details of system.


The exhaust system consists of a final collector, catalytic converter, exhaust silencers (average and terminal), connecting pipes and details of their suspension bracket (arms, collars, pillows). The exhaust system fastens to a body through arms and rubber pillows. At failure of any of system details operation of the engine is accompanied by the increased noise.

For maintenance of an exhaust system in good repair periodically check a condition of details. Check existence of the dispersed seams, burn-out and proyedaniye traces corrosion, and also other defects which are at the bottom of hit of exhaust gases in salon. The failed details are not subject to repair, they should be changed.

If details of system do not give in to removal because of прихвата owing to corrosion, it is necessary to remove them sharp. Usually this procedure is carried out in workshops by means of autogenous cutting. However, at desire to save on cost of these works and in the absence of own gas-welding equipment, резку it is possible to execute a hacksaw. In the presence of the compressed air резку it is possible to execute pneumatic scissors. At work dress points for protection of eyes against sawdust and a mitten.

At repair of an exhaust system observe the following rules:

      – details of an exhaust system of cнимайте one after another, since terminal section and finishing forward section;
      – to facilitate an otvorachivaniye of nuts and bolts grease them with getting liquid;
      – at replacement of pipes and exhaust silencers surely replace details;
      – at assembly grease all carvings with fixing structure;
      – between the bottom of a body and exhaust pipes there should be a gap to prevent an overheat of a floor and destruction of an anticorrosive covering and a rug. Special attention at assembly give to installation of catalytic converter and a heatinsulating guard.

Prevention

Catalytic converter works at very high temperature, its cooling needs a long time. Before removal of converter wait its complete cooling. Otherwise serious burns are possible.
