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 traces of corrosion. Restore the stripped thread in openings. It is very recommended to check tightness of the block of cylinders in workshops of car service in which there is the corresponding equipment. If defects are found, repair the block or replace.
3. Check existence of scratches and zadir on the internal surfaces of cylinders.
4. Measure the internal diameter of the cylinder in top (directly under a fillet), in average and in the lower part parallel to an axis of a bent shaft. Then take measurements at the same levels, but in the direction perpendicular axes of a bent shaft. Compare results of measurement to the values specified in the management. If on the surfaces of cylinders there are strong teases and scratches, or ovality and conicity of cylinders exceeds the set limits, then the block needs to be handed over in a workshop for boring and a honningovaniye. After repair pistons and rings of the repair sizes will be necessary.
5. If the condition of cylinders accepted wear of the cylinder and a gap between the cylinder and the piston do not exceed the established norms, then boring is not required. The honningovaniye remains the only necessary operation.
6. Before a honningovaniye establish covers of radical bearings of a bent shaft (without bearings), tighten bolts with the set moment.
7. The honningovaniye requires special adaptation with fine grinding heads, a large amount of oil, rags and the electric drill. Clamp adaptation in the electric drill, fix grinding heads and enter adaptation into the first cylinder. Well oil the surface of the cylinder, turn on the electric drill and periodically move it up and down in the cylinder.
8. At the same time on a surface of walls of the cylinder the structure of the thin lines which are crossed at an angle about 60 ° has to be formed.
9. All the time plentifully grease the surface of the cylinder. During rotation do not get adaptation. After switching off of a drill continue to move it up and down to a full stop, then squeeze adaptation legs with grinding heads and get from the cylinder. Wipe the cylinder from oil and repeat operation on other cylinders. If adaptation is absent or not desires to independently carry out a honningovaniye, then this operation can be executed in workshops for the acceptable payment. Satisfactory results turn out when using of the emery circle got on the electric drill, or even when performing operation manually by a skin.
10. After performance of a honningovaniye chamfer the top edges of the cylinder a small file to prevent jamming of rings at installation of the piston.
11. All block should be washed out warm water with detergent again to remove the remains of abrasive material from a honningovaniye. Clean a brush all channels and wash out flowing water. After washing dry up the block of cylinders and oil veretenny all processed surfaces. Prior to assembly you store the block under a plastic cover.
