3.1.2.12. Honningovaniye of cylinders

GENERAL INFORMATION

Device for a honningovaniye of the brush type


Persons who never carried out a honningovaniye are recommended to perform works with the help of "brush" adaptation.

Before assembly of the engine it is necessary to otkhonningovat cylinders to provide tightness of combustion chambers with a dense prileganiye of piston rings to walls of cylinders.

Devices of two types – flexible "brush" and adaptation with the sprung heads from a grinding stone are usually used to a honningovaniye of cylinders (the last was widely adopted most). Both devices yield good results, however flexible "brush" with which it is much easier to work will be suitable for the unexperienced motorist better. The honningovaniye also requires kerosene, or oil for a honningovaniye, rags and the electric drill. The electric drill has to work at small turns, at a constant speed of rotation. The big drill on a drill of 12-13 mm, or a drill with a variable speed of rotation at 3/8 inch (9–10 mm) will approach.


Prevention

In the absence of the device for a honningovaniye this operation can be executed for a small payment in workshops.


PERFORMANCE ORDER
1. Before a honningovaniye establish covers of radical bearings of a bent shaft (without inserts) and tighten bolts with the set moment.
2. Clamp adaptation in the electric drill, fix grinding heads and enter adaptation into the first cylinder.
3. Well oil the surface of the cylinder, turn on the electric drill and periodically move it up and down in the cylinder. At the same time on a surface of walls of the cylinder the structure of the thin lines (1) which are crossed at an angle about 60 ° has to be formed. All the time plentifully grease the surface of the cylinder. Do not remove excessive amount of material, finish a honningovaniye after operational development of a surface.

Prevention

Some manufacturers of piston rings recommend a little smaller angle of crossing of structure of thin lines, than 60 °. Study the instruction attached to piston rings.


4. 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. If the cylinder honningutsya by the brush, then switch off a drill, then rotating the brush in the direction of normal rotation, get it from the cylinder.
5. Wipe the cylinder from oil and repeat operation on other cylinders.
6. After end of a honningovaniye a small file chamfer the upper edge of each cylinder to prevent jamming of rings at installation of pistons in cylinders. Be careful, do not scratch a file of a wall of cylinders.
7. All block of cylinders should be washed out warm water with detergent again to remove the remains of abrasive material from a honningovaniye.

Prevention

Cylinders are considered pure if on the protirochny fabric which is not leaving pile, moistened with oil for the engine there are no traces of grayish color. Surely clean oil channels and openings a brush, wash out them flowing water.


8. After washing dry up the block of cylinders and oil veretenny all processed surfaces that will protect them from corrosion. Prior to assembly of the engine you store the block of cylinders under a plastic cover.
