Fig. 2.331. Components of system of production of the fulfilled car gases with the Z6 engine: 1 – cross-piece of the back tunnel; 2 – cross-piece of the forward tunnel; 3 – main muffler; 4 – the back sensor of concentration of oxygen with heating; 5 – the forward sensor of concentration of oxygen with heating; 6 – a pipe of recirculation of the fulfilled gases (from a final collector); 7 – element; 8 – arm of a final collector; 9 – clip; 10 – three-component catalytic converter; 11 – thermal screen of a final collector; 12 – laying of a final collector


Remove components in the order shown in the figure 2.331 on page 157.
Removal of a final collector / thermal screen of a final collector

ATTENTION
The excessive bend of an exhaust pipe can lead to its damage.

NOTE
At removal of a final collector, take aside the thermal screen of a final collector a little, weaken nuts, and then remove a final collector together with the screen. Address the following procedure.

Remove forward wheels.
Uncover the air filter and the case of the air filter.
Remove a pipe of recirculation of the fulfilled gases (from an inlet collector).
Remove knot of the valve of recirculation of the fulfilled gases.
Disconnect a steering shaft from the steering mechanism, disconnect steering drafts.
Disconnect a pressure head hose and a returnable hose.
Remove an engine No. 1 support.
Weaken bolts of the thermal screen of a final collector.
Take the thermal screen of a final collector a little aside and weaken nuts of a final collector.
Remove bolts of fastening of a forward cross-piece and the forward stabilizer of a suspension bracket.
Weaken bolts of fastening of a forward cross-piece and lower a forward cross-piece approximately by 100 mm.
