6.6.3. Removal and installation of system of production of the fulfilled gases
At 6-cylinder engines system of production of the fulfilled gases double, with double sections. However an order of works same, as well as on usual system. For replacement of separate knots and details follow indications of appropriate sections. Take care of acquisition of new details of fastening, and also of a stock of rubber suspension brackets and laying. At installation of knots of system pay attention to density of connections.
