1. Examine the block on existence of cracks and corrosion or rust traces. Examine carvings of openings of the block. At detection of defects it is necessary to repair or replace the block whenever possible.
2. Examine cylinders.
3. Measure diameter of each cylinder in the top average and bottom 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.
7. After completion of works insert new perepuskny the valve into the block of cylinders.
8. Hammer the valve into place.
