2. Examine cylinders.
3. Measure diameter of each cylinder in the top average and bottom its parts, parallel to an axis of a cranked shaft.

4. Measure diameter of each cylinder in the top average and bottom its parts, perpendicular to an axis of a cranked shaft.
5. The Konusnost of the cylinder is calculated as a difference between top and bottom in diameters. Ovality – as a difference between parallel and perpendicular measurements.
6. If the received results do not coincide with technical requirements, address to experts.
