7.3. Coupling installation
Coupling installation is spent to sequences, return to dismantle. The special attention is necessary for turning on the following:
- If former coupling is established, it is necessary to verify position of the marks noted at dismantle. Thanks to it coupling and flywheel balancing remains. New coupling is possible крепить bolts in any way as its static balancing is already executed at manufacturing;
- Aligning оправка
it is applied to a centering of a leading disk. This оправка
should enter into gearing of a leading disk and to have a pin approaching on the sizes for calling in the bearing of a cranked shaft (fig. 139
). It is possible to use an old shaft of a transmission also. Skilled mechanics can centre a leading disk and "by eye";
