Пленка вторичная подробности на сайте. Block of cylinders



If caps of channels of system of cooling fail to the canal of the block of cylinders, to take them, as a rule, it is impossible.


1. In easy blows of a hammer by a sharp part of a core beat out edges of caps of the block of cylinders so that caps were turned in openings.
2. Then get caps from openings, having picked up flat-nose pliers.
3. Remove with a shpatel all remains of a material of laying from the block of cylinders, being careful not to damage the demountable planes.
4. Remove covers of radical bearings and get bearings from the block of cylinders and covers. Inscribe cylinder number about which the removed radical bearing, and also a detail from which it was established taken (from a cover of the bearing or from a bed of the block of cylinders), put bearings, separately from each other.
5. Turn out and remove all carving caps of channels of the block of cylinders. It is almost impossible to take caps, therefore drill them and anew cut a carving a tap. At engine assembly all caps replace.
6. If the engine is strongly polluted, it is necessary to hand over it in a car-care center workshop for washing by a strong vapor jet, or in the hot chamber.
7. After cleaning of the block of cylinders in a workshop clean in addition all oil channels and openings. Almost in all autoshops on sale there are brushes for pro-cleaning of channels and openings. Wash out internal channels a stream of warm water until then while water does not become pure, carefully dry the block and grease proshlifovanny surfaces with veretenny oil that will protect them from corrosion. If there is a compressed air, blow the block and internal channels for drying acceleration.
8. If the block is polluted slightly, it is possible to be limited to washing by warm water with detergent and a rigid brush. Do not feel sorry for time and perform this work carefully. Irrespective of a way of washing very carefully clean oil channels and openings, dry the block and grease the processed surfaces with veretenny oil.
9. Carving openings should be passed in the block a tap that will provide correctness of indications of the moment of an inhaling at assembly. Passing by a tap will allow to clear carving openings of dirt, traces of corrosion and the hermetic remains, and also to restore the damaged carving.
10. At possibility blow openings a stream of the compressed air for removal of the remains of a material from passing of carvings by a tap. Now it is a high time to clear carvings of bolts of fastening of a head of the block of cylinders and covers of radical bearings.
11. Again establish covers of radical bearings, bolts tighten by hand.
12. Establish in the block new caps, previously having greased them with hermetic. For landing of caps it is required the special tool, however this operation it is possible to execute with identical quality in hammer blows on an opravka which diameter corresponds to a cap opening. The face head will be suitable for this purpose in 1/2 inches with the extension piece.
13. Be convinced of correctness of landing of caps, in lack of distortions. Otherwise leaks are possible.
14. Grease caps of oil channels with non-drying hermetic and screw them in openings of the block of cylinders. Be convinced of reliability of an inhaling of caps.
15. If engine assembly is not made at present, cover the block of cylinders with a polyethylene cover that will protect it from pollution.

Check of a technical condition

1. Before condition check carefully clear the block of cylinders.
2. Visually check absence on the block of cracks and corrosion traces. Check a condition of carvings, if necessary restore stripped a thread. It is very recommended to check existence of internal defects in the block of cylinders for what it is necessary to hand over the block in a car-care center workshop where there is the corresponding equipment. If the frequent overheat of the engine was observed, or level of cooling liquid went down owing to its loss, this check should be executed surely. If defects are found, repair the block or replace.
3. Check existence of chips and задиров on internal surfaces of cylinders.
4. Check ovality and a konusnost of cylinders. Measure internal diameter of the cylinder in the directions parallel and perependikulyarny engine axes. Ovality of the cylinder is defined as a difference of diameters measured in the directions A and Century of Konusnost of the cylinder is defined as a difference of diameters, izmenrenny in the directions A and B in the top and bottom planes.
5. Ability to "feel" the correct situation нутрометра is developed not at once. Therefore carry out measurements slowly, recheck result, be not convinced yet that diameter is measured precisely.
6. After installation нутрометра on cylinder walls the micrometer measures length exposed нутрометра which is equal to the measured internal diameter.
7. Measure internal diameter of the cylinder in top (directly under a fillet), in average and in the lower part parallel to an axis of a cranked shaft.
8. Then carry out measurements at the same levels, but in the direction perpendicular axes of a cranked shaft.
9. The Konusnost of the cylinder is defined as a difference of diameters in top and in bottom the planes. Ovality of the cylinder is defined as a difference of diameters measured in the directions perpendicular and parallel to an axis of the crankshaft. Compare results of measurement to standard values.
10. If on surfaces of cylinders there are strong teases and scratches, or ovality and a konusnost of cylinders exceeds the established limits, it is necessary to hand over the block in a workshop for boring and a honningovaniye. After restoration of the block pistons and rings of the repair sizes will be necessary.
11. With the help щупа and calibre check deformation of the demountable plane of the block of cylinders and a head of cylinders. If the deviation from the plane exceeds norm, the block follows прошлифовать in a car-care center workshop.
12. If a condition of cylinders accepted, wear of the cylinder and a gap between the cylinder and the piston do not exceed the established norms, boring it is not required. Everything that it is necessary to make – отхоннинговать cylinders (see subsection
