2. Cautiously clear the block of the consolidation rests.
3. Remove covers with loose leaves, designate them and store separately.
4. Turn out carving заглушки the block of cylinders (or drill, and then banish a carving).
5. At strong pollution of the block clean all channels a stream of steam and compressed air (it is recommended to carry out in car-care centre), wash out the block outside a washing-up liquid. Banish all carving apertures, clean and blow compressed air. Dry the block and grease веретенным with oil to protect from corrosion.

6. Banish all carvings of the block of cylinders, having cleared thereby of a dirt. Dry carving apertures to exclude breakage of the block of cylinders at the expense of a hydraulic pressure at заворачивании a bolt.
7. If the block is not so strongly polluted, it is possible to be limited to washing by a soap solution. Irrespective of a way of clearing very carefully wash out all internal lubricant channels and well dry. Walls of cylinders oil to prevent rust occurrence.
8. Establish covers of radical bearings, bolts tighten by hand.

9. Запрессуйте new заглушки without warps, preliminary having greased with their hermetic. Turn on non-drying hermetic new заглушки oil channels. Densely tighten заглушки.
