| 1. Visually check the block of cylinders for corrosion existence. Check integrity of a carving in carving openings. |
| 2. Check diameter of cylinders of the engine for wear on existence of a step in the top part of the cylinder. |
|
|
|
| 3. In the presence of the measuring tool measure diameter of a sleeve of each cylinder in the top part (under a wear step) in the center and at the basis parallel to an axis of a bent shaft. |
| 4. Then perform the same measurements perpendicular to an axis of a bent shaft and compare them to specifications. Repeat the procedure of measurement on other sleeves of cylinders. |
