2.42. Block of cylinders

GENERAL INFORMATION

Check of planeness of a surface of a prileganiye of a head of the block of cylinders

1. RECTILINEAR CORE
2. FLAT ЩУП


Measurement of diameter of an opening of the bearing

1. NUTROMER
2. BLOCK OF CYLINDERS

Measurement of a konusnost and ovality of the cylinder


 


Profile of the worn-out cylinder

 


To disassemble

PERFORMANCE ORDER
1. To remove caps of a shirt of cooling.
1а. To pick up a suitable bolt-samorez.
1б. To drill an opening in a cap.
1в. To screw in a self-cutting bolt.
1г. To take out a cap.
2. To dismantle carving jams of oil channels.
3. To remove camshaft bearings.
Prevention

The washing solutions containing caustic soda, damage a material of bearings. Therefore bearings which underwent influence of such solution, are subject to replacement. It is forbidden to clean bearings and aluminum details caustic soda solutions.



To clear


PERFORMANCE ORDER
1. The remains of sealants on interfaced surfaces.
2. Oil channels.
3. All deaf openings.
4. Mirrors of cylinders and the other processed surfaces by means of engine oil.

To check

PERFORMANCE ORDER
1. Deviations from planeness of the top plate of the block of cylinders. For check to use a rectilinear core and a set flat щупов, fig. Check of planeness of a surface of a prileganiye of a head of the block of cylinders. Small roughnesses can be carefully removed.
2. On existence of dents on the planes of a prileganiye of the oil pallet and a cover of a drive of a camshaft. It is possible to remove small defects with a thin flat file.
3. The Privalochny plane of the block of cylinders for a transmission case.
Prevention

Deformed привалоч the ny plane can lead to disk breakage with a gear wreath (it is established with an automatic transmission).


4. Temporarily to establish a cranked shaft. To measure palpation of a flange of a shaft.
5. Serviceability of carving openings. If necessary to clean a carving. The damaged openings to repair by means of screw plugs.
Prevention

Further checks and restoration of operability of details are necessary for carrying out at established on a place and the covers of radical bearings tightened by the demanded moment.


6. To be convinced of the correct installation of covers of radical bearings. Shooters on covers should be directed to a forward part of the engine.
7. Condition of openings of bearings. To measure by a nutromer diameters of openings, to check coaxiality of openings of bearings for cranked and distributive shaft. At deviations from norm to replace the block of cylinders. If there are defects on external surfaces of loose leaves, it is necessary to remove carefully small roughnesses from beds of loose leaves.
8. Mirrors of cylinders on existence of wear, ovality and a konusnost by means of a nutromer, fig. Measurement of a konusnost and ovality of the cylinder.
9. If cylinders are worn-out, they can be chiseled and отхонинговать for the next repair size. In this case in the Engine establish pistons and rings соответ the stvuyushchy increased size.
Prevention

When processing cylinders to leave a necessary allowance on honingovaniye operation under the final size corresponding to diameter of pistons.


10. If on mirrors of cylinders there are film deposits and cylinders are quite efficient, it is necessary to remove these deposits with the help хона and to replace piston rings.
11. Before processing of cylinders it is necessary to be convinced of purity and the correct form of honingovalny whetstones. Hon should be moved slowly along a cylinder axis for receiving the correct microrelief of a mirror (strips should settle down at an angle 45 degrees to a cylinder axis). After a honingovaniye it is necessary to wash up carefully mirrors of cylinders soap solution, to dry up and grease with engine oil. To carry out control measurements of cylinders.

To collect

PERFORMANCE ORDER
1. To establish to the place of a cap of a shirt of cooling. Ispolzovatgermetik of brand 1050026.
2. To establish into place carving jams of oil channels. Camshaft bearings.
