4.23. Honingovaniye of mirrors of cylinders
Before assembly of the engine the honingovaniye of mirrors of cylinders for the purpose of achievement of the correct landing to them of piston rings providing due tightness of combustion chambers is without fail carried out.
In the absence of near at hand necessary tools or unwillingness to independently carry out a honingovaniye, work for quite moderate payment can be charged to experts of a workshop of car service.
Before starting a honingovaniye, establish into place assembly of covers of radical bearings (without inserts) and tighten fixing bolts with the required effort.
Two types of khans for processing of mirrors of cylinders are issued: хон like "the bottle brush" and, more traditional, superficial хон in the form of a nozzle with the sprung grinding stones. Both tools provide necessary quality of processing of mirrors of cylinders though use of the first is more preferable to the inexperienced mechanic. Also enough rags, special honingovochny or just liquid lubricating oil, and also the electric drill as the drive for honingovochny nozzles will be required.
Act in the following order.
Upon completion of processing, use a file for removal of facets from the upper edges of cylinders — this processing is made with the purpose there were no difficulties with gas station in cylinders of pistons with the rings which are put on them. Observe extreme care — do not scratch a file a cylinder mirror.
In conclusion all block has to be washed carefully out by warm solution of soap water.
Cylinders can be considered washed out when after carrying out on a mirror the gray raid does not remain the white rags moistened with oil on it. Do not forget to clean a cylindrical brush all oil openings and channels, then wash out the block a water stream under a pressure.
After washing carefully dry the block and oil the pierced surfaces for protection them from corrosion. Prior to assembly of the engine wrap the block in a pure plastic bag.
