Set the steering mechanism to the middle position, dividing the full angle of rotation of the propeller shaft in half and aligning the mark on the end of the propeller shaft with the protrusion on the distributor housing.
By swinging the bipod, determine the presence of a gap in the meshing of the bipod shaft sector with the teeth of the ball nut. Gap is not allowed.
If there is clearance, adjust the engagement clearance, loosen the adjusting screw locknut and turn the fry arm shaft adjusting screw, turning the adjusting screw clockwise to eliminate the meshing clearance and tighten the locknut. Locknut tightening torque (26,7...33,0) Nm.
After adjustment, check the torque of the propeller shaft:
- turn the propeller shaft to the extreme left position and measure the moment of rotation of the propeller shaft to the right to the left within an angle of 90°. The moment must be within 80... 120 Nm;
- turn the propeller shaft to the extreme left position and measure the moment of rotation of the propeller shaft to the right to the left within an angle of 90°. The moment must be within 80... 120 Nm;
- turn the propeller shaft to the middle position and measure the moment of rotation of the propeller shaft to the right to the left within an angle of 90°. The moment should be within 120... 180 Nm.
The torque difference between the torque in the middle position and the torques in the extreme positions should be no more than 60 Nm for one specific mechanism.
Repeat the adjustment if necessary.
Warning. Adjustment of the gap in engagement, the steering gear is not removed from the vehicle, is strictly prohibited. When adjusting the clearance, the steering mechanism must always be in the middle position.
