For measurement of cylinders the cylindrical strelochny indicator by means of which it is possible to measure in the middle and in the lower part of the cylinder is required. If the strelochny indicator is absent, the following works cannot be carried out. Measurements of cylinders make in the longitudinal and cross-section direction. Besides, measurements should be carried out to 15 mm from the upper edge, in 15 mm from bottom edge and in the middle. In total it is required to make 6 measurements. All results of measurements write down and compare to the data provided in a size table and adjustments. It is necessary to consider that all cylinders even if the sizes of only one cylinder differ from the demanded should be chiseled. The deviation from the size in 0,20 mm from demanded value means that the cylinder should be chiseled. Pistons have only one repair size. The final size of the cylinder is defined at piston measurement according to drawing 11.1 data, that is 18,0 mm from a piston finger. Measurements are made under the lowermost flute of the piston. To the measured value it is necessary to add a gap of the piston of 0,04-0,06 mm. Besides, it is necessary to consider an allowance of 0,02 mm on a final honingovaniye in case cylinders have to be chiseled. For check люфта pistons measure diameters of cylinders and diameters of pistons as it was described above, and calculate a difference for each cylinder. If the result exceeds value of 0,20 mm, it is necessary to chisel cylinders to establish pistons of the increased size (there is only one size) as люфт reached limit of wear.
