Prokladochnye of a surface

On all cars of laying are applied to sealing of a place of a joint of interfaced surfaces of two or more details and serve for prevention of leakages of oils and liquids and maintenance in elevated pressure or depression assembly.

Often such laying before installation becomes covered by a liquid or pastelike sealing compound. Often under the influence of time, temperatures or pressure there is so strong "prikipaniye" of to each other interfaced surfaces that division of details becomes an exigeant task. With many cases dismantle of such assemblies is helped by an obstukivaniye them outside on perimeter of a place of a joint a hammer with soft the brisk. It is possible to use for this purpose as well a usual hammer, striking blows through a wooden or plastic pro-rate. It is not necessary to make an obstukivaniye of cast cases and fragile components. Whether at emergence of such difficulties always first of all check all fixture it is removed.

Avoid application for division of details a screw-driver or mount, entering them between interfaced surfaces as sealing surfaces thus can be easily damaged that further can be at the bottom of emergence of leaks. If a podrychazhivaniye of the "become attached" elements of assembly it is impossible to avoid, use for this purpose the handle from an old smetka, but remember thus that after all the formed chips should be carefully removed from interfaced surfaces and from within assembly.

After division of details their interfaced surfaces should be smoothed carefully out with a soskablivaniye of traces of a material of old laying. The hardened fragments of old laying can be softened previously by means of the converter of a rust or a special chemical composition then are removed from an interfaced surface with a scraper. As a scraper the piece of a copper tube with the flattened-out and pointed end in this case can be used. Use for this purpose of copper tube is recommended, as copper is usually softer than materials applied in the car that reduces risk of damage of an interfaced surface. Some laying easily can be removed by means of a copper brush, however, irrespective of the applied method, interfaced surfaces should become absolutely pure and smooth. If for any reason the interfaced surface appeared scratched, before assembly of components fill scratch with prokladochny hermetic. In most cases it is necessary to use not stiffening (or semi-stiffening) hermetic.
