Between flanges of a head of the block of cylinders and a final collector the sealing laying made of the pressed asbestos leaf reinforced by steel is established. At violation of tightness of this laying there is a break outside of the fulfilled gases which is followed by a characteristic sharp sound (the collector "secht"). If it is not possible to eliminate malfunction with tightening of fastening of a final collector, replace laying.

It will be required to you: face heads "on 13", "on 16".

1. Turn off three nuts of fastening of a reception pipe to a final collector and lower a reception pipe down.	2. Remove the thermoscreen of a final collector (see. "Removal and installation of thermoscreens").

3. Turn off eight nuts of fastening of a final collector.	4. Remove a final collector from hairpins.

5. Remove the thermoscreen...	6.... and the laying established under it.

7. Carefully clear privalochny surfaces of a head of the block and a final collector of the remains of old laying and a deposit.

8. Establish new laying and all removed details in the sequence, the return to removal.

9. Tighten nuts of fastening of a final collector evenly cross-wise.

Good advice In order to avoid burning of laying and for increase in its tightness we recommend to grease before installation of laying it on both sides a thin layer of graphitic lubricant. Grease hairpins of a head of the block of cylinders with graphitic lubricant.
