4.23. Хонингование mirrors of cylinders

Before engine assemblage it is without fail spent хонингование mirrors of cylinders for the purpose of achievement of correct landing to them of the piston rings, providing due tightness of chambers of combustion.

At absence near at hand necessary tools or unwillingness independently to carry out хонингование, work for quite moderate payment can be charged experts of a workshop of car-care centre.

Before to start to хонингованию, establish into place assemblage of covers of radical bearings (without loose leaves) and tighten fixing bolts with demanded effort.

Two types хонов for processing of mirrors of cylinders are issued: хон type «bottle ершик» and, more traditional, superficial хон in the form of a nozzle with подпружиненными grinding stones. Both tools provide necessary quality of processing of mirrors of cylinders though use of the first is more preferable to not skilled mechanic. Enough of the rags, special хонинговочного or simply liquid lubricating oil, and also an electrodrill as a drive for хонинговочных nozzles Is required also.

Operate in a following order.

 PERFORMANCE ORDER

  1. Clamp хон in an electrodrill cartridge, reduce подпружиненные grinding stones / rods ершика nozzles and fill last in the cylinder.

Do not forget to put on goggles or an obverse guard!

  1. Plentifully moisten a mirror of the processed cylinder with oil, include a drill and start to make a nozzle back and forth motions in the cylinder. Speed of vertical moving хона should provide drawing on a surface of a mirror of the cylinder of a mesh pattern with a corner of crossing of the parties ячеи nearby 60 °. Do not feel sorry some oil and try not to remove from a surface of walls of the cylinder of more material, than it is really necessary for achievement of demanded result.

Manufacturers of piston rings can make own demands to a corner of crossing of the parties ячеи a mesh pattern, - attentively familiarise with the instruction on packing ремнабора.

  1. Do not take хон from the cylinder to a full stop of a drill! Continue to make back and forth motions by a nozzle until it will not stop to rotate. After a drill stop compress grinding stones and take хон from the cylinder. At using хоном type «bottle ершик» wait a full stop of a drill, then take a nozzle, continuing to rotate manually a cartridge in a normal direction.
  2. Wipe rags a mirror of the cylinder and pass to хонингованию the following.

On termination of processing, take advantage надфилем for removal of facets from upper edges of cylinders, — the given processing is made so that there were no difficulties with refuelling in cylinders of pistons with the rings put on them. Observe extreme care, — do not scratch надфилем a cylinder mirror.

In summary all block should be washed carefully out a warm solution of soap water.

It is possible to consider cylinders washed out when after carrying out on a mirror the white rags moistened with oil on it does not remain a grey touch. Do not forget to clean a cylindrical brush all oil apertures 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 their protection against corrosion. Prior to the beginning of engine assemblage wrap the block in a pure polyethylene package.
