Fig. 1.62. Pendulum engine mount. 1 - elastic cushion of the front left pendulum suspension; 2 - pendulum suspension bracket on the gearbox; 3 - pendulum suspension bracket on the cylinder head; 4 - pendulum suspension travel limiter; 5 - pendulum suspension cover; 6 - elastic cushion of the front right pendulum suspension; 7 - jet thrust
The engine is suspended on two elastic cushions (1 and 6. Fig. 1.62). The moment in the longitudinal direction is perceived:
- at the bottom of the power unit by jet thrust (7);
- at the top of the power unit by the travel limiter (4).
Note: To avoid damage to the elastic cushions, do not exceed 20° angular movement relative to the vertical.
Adjusting the longitudinal travel limiter
- Use a support to support the power unit.
- Loosen the pendulum suspension travel limiter mounting bolts (4).
- Insert the centering fork Mot. 1289-02 into the slots of the pendulum cover (5).
Note: This operation can only be performed with the bracket and cushion installed on the gearbox and their mounting bolts tightened to the required torque. Then tighten the torque rod.
