| THE GENERAL DATA |
Theoretically new cylinder is ideally round. Piston work leads to deterioration of walls under right angles to piston fingers because of lateral loading. This deterioration takes place mainly in this section of the cylinder because of a friction about piston rings.
Deterioration first signs can be noticed, having felt a step directly near to the top part of the cylinder where the top piston ring reaches. If such step is absent, means, deterioration of the cylinder is insignificant and there are no the losses caused by a lack of a compression or the superfluous expense of oil because of deterioration or damage of piston rings or pistons.
In the presence of a special micrometer for cylinder measurement to measure diameter of the cylinder in a plane below the top edge of the block of cylinders, and also diameter of an aperture in the bottom part of the cylinder in the same plane.
If in any of cylinders there are appreciable scratches or furrows, he also demands расточки. This phenomenon usually specifies in damage of the piston or rings. If at least one of cylinders requires in расточке, it is necessary to execute this operation for all cylinders and to establish new pistons and piston rings of the repair size.
