Prokladochnye surfaces

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

Often such linings before installation become covered liquid or pastelike sealing компаундом. Often under the influence of time, temperatures or pressure occurs so strong "прикипание" to each other interfaced surfaces that division of details becomes an exigeant problem. With many cases to dismantle of such assemblages helps обстукивание them outside on perimetre of a place of a joint a hammer with soft the brisk. It is possible to take advantage for this purpose as well of a usual hammer, putting blows through the wooden or plastic prorate. It is not necessary to make обстукивание cast cases and fragile components. Whether at occurrence of such difficulties always first of all check weigh fixture it is removed.

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

After division of details their interfaced surfaces should be smoothed carefully out with соскабливанием traces of a material of an old lining. The hardened fragments of an old lining can be preliminary softened by means of the converter of a rust or a special chemical compound then are removed from an interfaced surface by 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 a copper tube is recommended, as copper usually is softer than materials applied in the car that reduces risk of damage of an interfaced surface. Some linings 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 has appeared scratched, before assemblage of components fill a scratch прокладочным with hermetic. In most cases it is necessary to use not stiffening (or semistiffening) hermetic.
