d) adjust the left-hand and right-hand
steering tie-rods by lengthening or
shortening them the same amount; to
do this, loosen the locknuts (3, 5, 6,
8) and, turning the left- and right-
hand tubes (7, 4), set the required
length.
e) ascertain the wheel toe-in, for which
purpose measure the distance
(measure Г) between the inner rim
beads of the wheels at the front (ap-
proximately at the height of wheel
centres) and mark the points of
measurement with chalk. Then move
the tractor forward so that these
marks come rearwards to the same
height and measure the distance be-
tween the marked points (measure
В). The second measurement should
be greater than the first one; the dif-
ference between the second, B, and
the first, Г, measurements is equal to
the wheel toe-in and should be with-
in 0…8 mm.
If required, adjust the toe-in by
changing the length of the steering
tie-rods. In doing so, lengthen or
shorten the left-hand and right-hand
tie-rods by an equal amount;
f) check again the pitman arm for being
in the midposition (using a feeler) and
the difference in measurements В
and Г;
g) having completed the adjustment of
wheel toe-in, securely fix the steering
tie-rod tubes with locknuts.
7.6.10. THE STEERING CONTROLS
Maintenance Servicing of the Steering
Mechanism Drive
Servicing of the steering mechanism drive
consists in checking the tightness of
threaded joints at regular intervals.
To ensure a minimum level of vibration at
the steering wheel, carry out adjustment
operations on the steering column, as fol-
lows:
• remove the snap-on cover (5) (see
Fig. 61);
• loosen the clamp (4) and remove the
steering wheel (6);
• back off the locknut (3);
• screw on the nut (2) down to the con-
tact with sleeve (1), so that clearances
in connections have been taken up;
• back off the nut (2) 1.5 turns and lock
it with locknut (3).
• reinstall the steering wheel (6) and
adjust its position as to height.
