3.1.2.12. Honningovaniye of cylinders

GENERAL INFORMATION

The adaptation for an ershik type honningovaniye

To persons who never carried out a honningovaniye, it is recommended to perform works by means of the ershik type adaptation.

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

Adaptations of two types are usually applied to a honningovaniye of cylinders – flexible "ершик" and the adaptation with podpruzhinenny heads from a grinding stone (the last gained the widest circulation). Both adaptations yield good results, however for the unexperienced motorist will be suitable flexible "ершик" better, to work with which much easier. The honningovaniye also needs kerosene, or oil for a honningovaniye, rags and an electrodrill. The electrodrill should work at small turns, at constant speed of rotation. The big drill on a drill of 12-13 mm, or a drill with variable speed of rotation on 3/8 inches (9–10 mm) will approach.

Prevention

In the absence of the adaptation 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 cranked shaft (without loose leaves) and tighten bolts with the set moment.
2. Clamp the adaptation in an electrodrill, fix grinding heads and enter the adaptation into the first cylinder.
	3. Well oil a cylinder surface, include an electrodrill and periodically move it up and down in the cylinder. Thus on a surface of walls of the cylinder the structure of the thin lines (1) which are crossing at an angle about 60 ° should be formed. All the time plentifully grease a cylinder surface. Do not remove excessive quantity of a material, a honningovaniye finish after surface operational development.
Prevention Some manufacturers of piston rings recommend a little smaller corner of crossing of structure of thin lines, than 60 °. Familiarize with the instruction attached to piston rings.
4. 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. If the cylinder хоннингуется ershiky, switch off a drill, then rotating ершик 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 honningovaniye end by a small file remove facets from 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 again warm water with detergent to remove the remains of an 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 will be 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 grease with veretenny oil all processed surfaces that will protect them from corrosion. Prior to the beginning of engine assembly the block of cylinders store under a plastic cover.
