2.2.17. Honingovaniye of cylinders Before engine assembly cylinders it is necessary отхонинговать that piston rings sat down properly and provided the best possible tightness of the chamber of combustion.

|
If you have not enough tools or you do not want to be engaged in a honingovaniye, the majority of mechanical workshops for the acceptable price will make this work. |
|
|
- Before a honingovaniye of cylinders establish covers of radical bearings and tighten bolts with the effort given in the Size table and adjusting data at the end of the Management.
- Two types of khans are usually available: flexible хон or such as “a brush for bottles” and the most widespread grinding хон with podpruzhinenny abrasive stones. Both types of khans are suitable for this work, however, for less skilled mechanic хон such as “a brush for bottles”, probably, will be simpler in the address. Also some liters of kerosene or oil for a honingovaniye, rags and an electric drill is required. Act as follows.
|
|
- Establish хон in a drill, compress stones in one bunch and insert a bunch into the first cylinder. Do not forget to put on goggles or a mask.
|
|
|
- Grease the cylinder with oil enough for a honingovaniye, include a drill and move the khan up and down so that on a wall of the cylinder the thin network of being crossed lines was formed. It is ideal, if lines of a grid are crossed at an angle approximately in 60 °. Be convinced that greasing enough and do not remove a material more than it it is necessary for receiving a demanded surface.
|
|
|
Manufacturers of piston rings can establish a smaller corner of crossing of a grid, than usual 60 ° - read and follow the instructions attached to new rings. |
- Do not take хон at its rotation from the cylinder. On the contrary, switch off a drill and continue to move the khan up and down to its full stop, then compress stones in one bunch and take хон. If it is used хон such as “a brush for bottles”, switch off a drill and, taking хон from the cylinder, rotate a cartridge in the normal direction.
- Remove from the cylinder oil and repeat operation for other cylinders.
- After honingovaniye end by a small file chamfer at the upper edges of cylinders that piston rings at installation did not jam. Be very careful, that the end of a file not to scratch a wall of cylinders.
- All block of cylinders is necessary for washing up very carefully again warm, soap water to remove the abrasive sand formed at a honingovaniye.
|
|
It is possible to consider cylinders pure when white, not leaving fibers, the fabric moistened with pure impellent oil which wipe the cylinder, does not collect more the remains of the sand leaving on a fabric gray spots. Do not forget to clean a brush all openings and channels of oil pipelines and to wash out them flowing water. |
