2.7.2. Removal and installation of a final collector

Fig. 2.265. Details of a final collector: 1–1 – a final collector (with the sensor of concentration of oxygen); 1–2 – a final collector (without sensor of concentration of oxygen); 2 – laying of a final collector; 3 – the sensor of concentration of oxygen with heating (if is available); 4–1 – a cover of a final collector (with the sensor of concentration of oxygen); 4–2 – a cover of a final collector (without sensor of concentration of oxygen); 5 – engine hook; 6 – amplifier of a final collector; 7 – laying; 8 – nut of fastening of a final collector; 9 – bolt of the amplifier of a final collector; 10 – bolt of an exhaust pipe; 11 – bolt of fastening of a final collector

Disconnect a wire from a negative conclusion of the rechargeable battery.

ATTENTION To avoid risk of receiving burns, do not touch system of release until it cooled down. Service of system of release has to be carried out only after the system cools down.

Disconnect the socket of the sensor of concentration of oxygen with heating 1 (if is available) and disconnect it from fastening.

Uncover a final collector of 2 (fig. 2.266).

Remove the amplifier of a final collector 1.

Fig. 2.267. Amplifier of a final collector and exhaust pipe No. 1

Disconnect an exhaust pipe No. 1 2 from a final collector (fig. 2.267).

Fig. 2.268. Final collector

Remove a final collector 1 with laying from a head of the block of cylinders (fig. 2.268).

Fig. 2.269. Fastening of a final collector

Establish new laying on a head of the block of cylinders. Then establish a final collector. Tighten bolts and nuts of fastening of a collector the nominal force of an inhaling.

Moment of an inhaling of a bolt and nut of a final collector (a): 50 N · m.

Establish new laying and attach an exhaust pipe No. 1 1 to a final collector (fig. 2.267).

Delay fastening of a pipe the nominal force of an inhaling.

Moment of an inhaling of a bolt of an exhaust pipe No. 1 (a): 55 N · m.

Establish the amplifier of a final collector 2.

Tighten bolts of fastening of the amplifier of a final collector the nominal force of an inhaling.

Moment of an inhaling of a bolt of the amplifier of a final collector (b): 55 N · m.

Establish a cover of a final collector of 2 (fig. 2.266).

Connect the socket of the sensor of concentration of oxygen with heating 1 and reliably fix the socket in an arm (if is available) (fig. 2.266).

Connect a wire to a negative conclusion of the rechargeable battery.

Check system of release for leaks.
