Front Wheel Toe-In Adjustment (trac-
tors equipped with HSCU)
Following changes in the wheeltrack
width, be sure to adjust the front wheel
toe-in by changing the length of the
steering rod (see Fig. 18d).
1. Set the required inflation pressure in
tyres (refer to instructions under
6.9.3).
2. Run the tractor straight forward at
least 3 m and stop.
Apply the parking brake.
3. Check to see that the hub reducing
gear bodies (on tractors equipped with
a FDA) or the steering knuckles (on
tractors «Belarus» 80.1/80.2 (2
х4)) be
advanced to the same amount "B"
from the FDA housing or the front axle
tube, respectively.
4. Measure the distance "C" between
two opposite points on the rim edge,
behind the front axle, at the height of
wheel axle.
5. Run the tractor forward, so that the
front wheels turned through approx.
180°, then, measure the distance "
А"
in front of the front axle, between the
same points as in case of taking di-
mension "
В". The toe-in is correct, if
the measured dimension "
А" is 0-8
mm less than the dimension "
В".
If the toe-in measurements are incon-
sistent with these values, proceed as
follows:
6. Loosen the locknuts (1), (3) on the ad-
justing tube (2) of the steering rod.
7. Turning the tube, set the required
amount of toe-in.
8. Tighten up the locknuts (1), (3).
