Checking the angular free play of the steering wheel is carried out daily with the engine idling by rocking the steering wheel in both directions until the steering wheels start to turn
The steering wheel free play must not exceed 15°.
Checking the free play should be done on the car with the front wheels straight ahead.
If there is an angular free play of the steering wheel that is more than acceptable, it is necessary to determine which node results in an increased angular free play, for which it is necessary to check the state of adjustment of the control rods, the adjustment of the steering mechanism, the clearances in the cardan joints of the steering and the tightening of the wedges of the cardan shaft.
If there is a violation of the adjustment of the steering mechanism or rods, the necessary adjustment should be made.
If there are increased gaps in the cardan joints, the cardan shaft should be replaced or repaired.
After making sure that the listed units are in a satisfactory condition, you should check the tightening of the nut 19 of the thrust bearings (Figure 2).
Axial movement of the steering wheel is not allowed.
If there is an axial movement of the steering wheel, it is necessary to tighten the nut 1 (Fig.1 ), after unbending the tabs of the lock washer.
After adjustment, one of the antennae should be bent again into the groove of the nut.
The moment of rotation of the steering shaft, disconnected from the cardan shaft, should be equal to 3-8 kgf.
Excessive tightening of the nut 1 with its subsequent unscrewing to obtain the specified torque of the shaft 7 (see Figure 3) is unacceptable, as it can damage the bearing 4.
