3.3.10. Block of cylinders



Caps of channels of system of cooling are densely pressed in the block of cylinders.

1. In blows by a stupid part of a core turn caps (a photo at the left) and get flat-nose pliers (a photo on the right).
2. Carefully clear the block of the consolidation remains.
3. Remove covers of radical bearings and get bearings from the block of cylinders and covers. Designate all details and store so that them not to mix.
4. Clean all channels a vapor jet and the compressed air (it is recommended to carry out in car-care center), wash out the block outside detergent.
5. Banish all carving openings, clean and blow the compressed air.
6. Dry the block and grease the processed surfaces with low-viscous oil. For cleaning turn out caps of oil channels.
7. Establish covers of radical bearings, bolts tighten by hand.
8. Press new caps without distortions, previously having greased them with Permatex N2 hermetic.
9. Turn on the same hermetic of a cap of oil channels.

Condition check

1. At detection of outer defects (cracks and chips), repair the block or replace. It is 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.
2. Check a surface condition, ovality and a konusnost of cylinders, having measured diameter in three planes, the cylinder under a fillet, in the center and in the most lower part, in the directions parallel and perpendicular block axes.
3. Carry out measurements by means of telescopic нутрометра.
4. If results differ from standard, it is necessary to hand over the block in repair. After restoration of the block pistons and rings of the repair sizes will be necessary.
5. 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, cylinders it is required отхоннинговать (see subsection 3.3.11).
6. Check deformation of the demountable plane of the block of cylinders. If the deviation from the plane exceeds norm, the block follows прошлифовать in car-care center.
