THE GENERAL DATA

Check of planeness of a surface прилегания heads of the block of cylinders

1. THE RECTILINEAR CORE 2. FLAT ЩУП

Measurement of diameter of an aperture of the bearing

1. НУТРОМЕР 2. THE BLOCK OF CYLINDERS

Measurement конусности and ovality of the cylinder


Profile of the worn out cylinder


To disassemble

PERFORMANCE ORDER

1. To remove заглушки cooling shirts. 1а. To pick up a suitable bolt-samorez. 1б. To drill an aperture in заглушке. 1в. To screw in a self-cutting bolt. 1г. To take out заглушку. 2. To dismantle carving stoppers of oil channels. 3. To remove camshaft bearings. The prevention The washing solutions containing каустическую soda, damage a material of bearings. Therefore bearings which have undergone to influence of such solution, are subject to replacement. It is forbidden to clean bearings and aluminium details solutions каустической soda.

To clear

PERFORMANCE ORDER

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

To check up

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 прилегания heads of the block of cylinders. Small roughnesses can be cautiously removed. 2. On presence of dents on planes прилегания the oil pallet and a cover of a drive of a camshaft. Small defects can be removed a thin flat file. 3. A privalochnuju plane of the block of cylinders for crankcase transmissions. The prevention Deformed привалоч ная the plane can lead to breakage of a disk 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 apertures. If necessary to clean a carving. The damaged apertures to repair with the help ввертных plugs. The prevention The further checks and restoration of working capacity of details are necessary for spending at established on a place and the covers of radical bearings tightened by the demanded moment. 6. To be convinced of correct installation of covers of radical bearings. Arrows on covers should be directed to a forward part of the engine. 7. A condition of apertures of bearings. To measure нутромером diameters of apertures, to check up соосность apertures 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 cautiously small roughnesses from beds of loose leaves. 8. Mirrors of cylinders on presence of deterioration, ovality and конусности with the help нутромера, fig. Measurement конусности and ovality of the cylinder. 9. If cylinders are worn out, they can be chiseled and отхонинговать the next repair size. In this case in the Engine establish pistons and rings соответ ствующего the increased size. The prevention At processing of cylinders to leave a necessary allowance on operation хонингования under the definitive size corresponding to diameter of pistons. 10. If on mirrors of cylinders there are film adjournment and cylinders are quite efficient, it is necessary to remove these adjournment with the help хона and to replace piston rings. 11. Before processing of cylinders it is necessary to be convinced of cleanliness and the correct form хонинговальных брусков. Хон it is necessary to move slowly along an axis of the cylinder for reception of a correct microrelief of a mirror (strips should settle down at an angle 45 degrees to a cylinder axis). After хонингования it is necessary to wash up carefully mirrors of cylinders a soap solution, to dry up and grease with engine oil. To spend control measurements of cylinders.

To collect

PERFORMANCE ORDER

1. To establish into place заглушки cooling shirts. Использоватьгерметик marks 1050026. 2. To establish into place carving stoppers of oil channels. Camshaft bearings.
