3.4.15. Honingovaniye of cylinders

1. Carefully clear the block of cylinders, be once again convinced that the fillet on the top edge of the cylinder is completely removed.
2. Visually check absence on the block of cracks and corrosion traces. Restore stripped a thread in openings. It is very recommended to check tightness of the block of cylinders in car-care center workshops in which there is the corresponding equipment. If defects are found, repair the block or replace.
3. Check existence of scratches and задиров on internal surfaces of cylinders.
4. 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. Then carry out measurements at the same levels, but in the direction perpendicular axes of a cranked shaft. Compare results of measurement to values specified in the management. 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 repair 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, boring it is not required. The unique necessary operation there is a honningovaniye.
6. Before a honningovaniye establish covers of radical bearings of a cranked shaft (without bearings), tighten bolts with the set moment.
7. The honningovaniye needs the special adaptation with melkodispersny grinding heads, a large amount of oil, rags and an electrodrill. Clamp the adaptation in an electrodrill, fix grinding heads and enter the adaptation into the first cylinder. Well oil a cylinder surface, include an electrodrill and periodically move it up and down in the cylinder.
8. Thus on a surface of walls of the cylinder the structure of the thin lines which are crossing at an angle about 60 ° should be formed.
9. All the time plentifully grease a cylinder surface. During rotation do not get the adaptation. After switching off of a drill continue to move it up and down to a full stop, then compress adaptation legs with grinding heads and get from the cylinder. Wipe the cylinder from oil and repeat operation on other cylinders. If the adaptation is absent or not desires independently to carry out a honningovaniye, this operation can be executed in workshops for an acceptable payment. Satisfactory results turn out when using the nazhdachny circle got on an electrodrill, or even at operation performance manually a skin.
10. After performance of a honningovaniye chamfer the top edges of the cylinder a small file to prevent jamming of rings at piston installation.
11. All block again should be washed out warm water with detergent to remove the remains of an abrasive material from a honningovaniye. Clean a brush all channels and wash out flowing water. After washing dry up the block of cylinders and grease with veretenny oil all processed surfaces. Prior to the beginning of assembly the block store under a plastic cover.
