1. Previously the block has to be compensated carefully (to see the Cleaning of the block of the motor). 2. Do the extern inquiry of the block as for the identification of aspects of corrosion, slits and other damages. Check a condition of a woodcarving of very fast openings. Also it will be reasonable to do on trial of the block of the existence of the slits hidden in the conditions of a workshop of the service of the car with the use of the special diagnostic equipment. In case of the detection of defects the block is subject to repair of recuperation or substitution. 3. Check a condition of mirrors of cylinders. 4. The sizes of estimate that happen of conicity and ovality of cylinders (companions see illustrations).
5th. Diameter of measure of each one of cylinders in top (straightly below limit of use of step), the central and lower sections, in the beginning in the airplane of a parallel axle of an end of inclination (V), then – perpendicular to an axle of the block (A).
5b. The measurement of diameters of cylinders follows that it does through a telescopic nutromer and a micrometer. The capacity is correct to use a nutromer it comes not at the same time – they do not hurry, do several measurements until one secures of the conclusions fairness in absolute.
6. After the diameter is registered by a nutromer, measure the last thing with a micrometer (to see an illustration).
