1. Examine the block on existence of cracks and traces of corrosion or a rust. Examine carvings of openings of the block. At detection of defects the block needs to be repaired or replaced whenever possible. |
2. Examine cylinders. |
3. Measure diameter of each cylinder in the top average and lower parts, parallel to an axis of a bent shaft. |
4. Measure diameter of each cylinder in top average and lower its parts, perpendicular to an axis of a bent shaft. |
5. Conicity of the cylinder is calculated as a difference between the top and lower diameters. Ovality – as a difference between parallel and perpendicular measurements. |
6. If the received results do not coincide with technical requirements, address experts. |
|
7. After completion of works insert new perepuskny the valve into the block of cylinders. |
|
8. Hammer the valve into place. |
