3.8. Sensor of frequency of rotation of the engine

The arm of the sensor of frequency of rotation of the engine can move at the expense of the extended openings. The provision of an arm is adjusted and cannot change.
If by mistake bolts of fastening of an arm unscrewed and the arm moved, establish it into place as follows.
Turning a bent shaft of the engine in the direction of its working rotation for a bolt of fastening of a pulley of a bent shaft, install the piston of the first cylinder in VMT.

Turn out the ignition moment sensor from an arm. Instead of the sensor of the moment of ignition screw the adjusting screw 3242 (see fig. 3.1-53).

Fig. 3.1-69. Use of the special tool 3308 (1) for combination with a gear wreath of a flywheel



Turn out bolts of fastening of the sensor of frequency of rotation of the engine and remove it. Instead of the sensor of frequency of rotation install the special tool 3308 (fig. 3.1-69) so that it was combined with a gear wreath of a flywheel.
Tighten the required moment bolts of fastening of an arm of the sensor of the moment of ignition.
Further installation is carried out to the sequences, the return to removal.
