On the dismantled engine the so-called intercepting device (1) which is combined with an arm (2) transmissions is visible. The sense of it consists in propping up a transmission which at the dismantled engine differently could fail downwards. Certainly, the same effect can achieve if to prop up it from below. |
The description of dismantle of engines of all models would leave for limits of possibilities of this management. Here some essential moments, concerning this theme are resulted only:
