Cleaning

PERFORMANCE ORDER

Remove from the block all components established outside and gauges. Упершись stupid выколоткой in edge выжимной stoppers, develop it in the landing nest under 90 °. After all stoppers will be developed, they will be simple enough for taking from the engine by means of nippers. Scratch out from an interfaced surface of the block all traces of a material of an old lining, — try not to leave scratches and задиров. Turn out all carving заглушки oil galleries. Заглушки can appear tightened very hardly up to that they should be drilled with the subsequent restoration of a carving in the block. At assemblage заглушки are subject to replacement. On diesel engines remove sprays of giving of oil on pistons. On engines of 1.7 l sprays запрессованы in the block and their removal can be made only with application of special adaptation Opel, on engines of 2.0 l sprays are fixed by bolts. Remove from the block of a cover of all radical bearings and take from the beds loose leaves of the last. At once mark the taken loose leaves by means of an adhesive tape on an accessory to the bearing and bed in it (the block or a cover), then will put them aside. At strong external pollution of the engine it is necessary to deliver it in a workshop of car-care centre for carrying out of steam or thermal processing. After return of the block from a workshop once again carefully clean all oil apertures and galleries — for this purpose special cylindrical brushes of the special form (ask in shops of automobile accessories) are issued. Wash out cavities and channels warm water, — continue washing until from an opposite side of the block pure water will not start to follow. Carefully dry the block, then slightly grease all pierced surfaces with liquid oil for their protection against corrosion. In the presence of access to a source of compressed air take advantage of it for acceleration of process of drying of the block and a purge of remote cavities and channels. At work with compressed air do not forget to put on goggles! At strong pollution or зашлаковывании the block it is necessary to resort to щеточной to cleaning by hot water with soap. It is not necessary to try to save time at the expense of neglect carefulness of cleaning of the block. Without dependence from the chosen way, track carefulness of procleaning of remote cavities, channels and apertures. In summary dry the block and grease the pierced surfaces with liquid oil for their protection against corrosion. Banish all carving apertures in the block a tap of the corresponding size for the purpose of maintenance of a guarantee of conformity of indications of the indicator динамометрического a key to really developed efforts of a tightening of fixture at engine assemblage. Whenever possible, blow then the apertures banished by a tap the compressed air, having removed from them all small dust and a shaving. Having finished processing of apertures, walk лежкой by a carving part of bolts of fastening of covers of bearings and heads of cylinders. Establish to the place of a cover of radical bearings, by hand having tightened their fixture. Grease sealing surfaces new выжимных stoppers with hermetic of type Permatex 1 and establish them on the regular places in the block. Track perpendicularity of landing of stoppers, — will take advantage most correctly special cylindrical оправкой, however the face head of the suitable size which should rest only against an internal part of a face surface of a stopper (not in a fillet can quite replace it!). Grease with not hardening hermetic of type Permatex 2 carving part new заглушек oil galleries (alternatively wind with their tape ФУМ). Screw заглушки on the regular places and tighten as it is possible more strongly. On diesel engines zapressujte/приболтите on the places sprays of giving of oil on pistons. If be not going to start at once engine assemblage, place the block in the big polyethylene package for protection of its pollution.
