2.2.6. Hermetic removal

Fig. 2.87. Removal of old hermetic

After extraction of assembly bolts and nuts, use the suitable tool for hermetic removal (fig. 2.87).

ATTENTION Try not to damage a detail surface.

Delete hermetic as it is possible more carefully from surfaces, deepenings and from openings of assembly bolts by means of the suitable tool, for example, a scraper. If it is necessary, heat up a surface a little and remove particles of the dried-up hermetic by means of a piece of the matter moistened with gasoline.

Fig. 2.88. Laying of new hermetic

Having finished operations put new hermetic (fig. 2.88).

Try to use firm hermetic or its equivalent.

After laying of new hermetic wait for 5 mines and establish the interfaced detail. Remove surplus of hermetic with a matter slice.

Tighten assembly bolts.
