| 1. Check an internal part of the case of the cylinder on lack of a rust, dot corrosion or development. Clear the dismantled details in solvent and blow all details and channels the compressed air.
2. Check a piston cuff on lack of wear.
3. Check the piston on lack of a rust, dot corrosion or development.
4. Check a tube of a hydraulic drive of coupling on absence of damages.
5. Measure internal diameter of the main cylinder of coupling and external diameter of the piston.
|
|
Measurement of internal diameter of the main cylinder of coupling carry out in three sections (in the basis, the center and top) in two perpendicular directions.
|
6. If the gap between the piston and the cylinder exceeds admissible value, replace the main cylinder and / or the piston assembled.
Gap: 0,15 mm
