During inspection of the steering knuckles, check the
serviceability of adjusting bolts 1 (Fig. 9.25) and steering stop
bolts 3. The value of steering angle B of the right wheel to the
right, and of the left wheel to the left should be within the limits
of 31-32°. The increased steering angle of the wheels results in
the contact of the wheel with the suspension parts.
It is not required to add the grease into the spherical pins and
into the ball struts in-service. The grease in the units is replaced
during maintenance.
Adjustment of steering knuckle pins 2 (Fig. 9.26) tightening
at works is carried out at pre-load along the common axle shaft
of the pins.
During operation of the vehicle, pay special attention to the
condition of the tightening of the steering knuckle pins. At the wear
of the interacting spherical surfaces of liners 3 or pins 2 the pre-load
disappears and the air gap appears along the common axle shaft of
the pins.To remove the air gap tighten clamping bush 10.
Front driving axle operation with air gaps in the pins units can
lead to premature upper pin liner failure.
It is easier to tighten clamping bush 10 of the lower pin while
in operation:
- unscrew nut 13;
- remove shield 12 with spacer 11;
- using the special wrench tighten clamping bush 10 to remove
the air gap (hit the threaded end of the pin with a copper hammer
beforehand);
- by turning the wrench by 10-20° tighten this bush to obtain
pre-load along the common axle shaft of the pins;
- install bracket with a spacer;
- tighten nut (see Annex 2).
