1. Check a condition of frictional overlays of a disk of coupling and in the presence of oil traces on them or mechanical damages replace a coupling disk. |
| 2. Check reliability of zaklepochny connections of frictional slips to a coupling disk. In the presence of defects, replace a coupling disk. |
|
3. Check a vystupaniye of frictional slips over heads of rivets. If a vystupaniye less admissible, replace a coupling disk. Vystupaniye: 0,3 mm
