| 1. Clear a cranked shaft, using the corresponding solvent, and drain it compressed air. |
| 2. Check radical and shatunny necks of a cranked shaft for wear, corrosion and cracks. |
| 3. Wear of a shatunny neck is characterized by metal knocks during the operation of the engine, especially under loading on small turns, and reduction of pressure of oil. |
| 4. Wear of radical necks of a cranked shaft is characterized by strong vibration of the engine and the metal knock increasing at increase in turns of the engine, and also reduction of pressure of oil. |
| 5. Check necks of a cranked shaft for a roughness. Any noticeable roughness specifies that the cranked shaft needs to be pereshlifovat or replaced. |
|
6. If the cranked shaft was pereshlifovan, check agnails round openings for greasing. In the presence of agnails remove them with a small file or a shaber. |
|
7. Carefully clear openings and channels of shaving. |
|
8. Using a micrometer, measure diameter of radical and shatunny necks of a cranked shaft and compare results with technical requirements. Perform measurement of necks in several points both on diameter, and on the neck length that will allow to reveal ovality and conicity if it is present. |
|
9. Check surfaces of contact of oil consolidation on each end of a cranked shaft for wear and other damages. If wear of a neck of a cranked shaft too big, perhaps, is required replacement of a cranked shaft. |
