Front axle system - Powered front axle
Four-Wheel Drive (4WD) axle - Toe in adjust
When travelling forward in a straight path, the wheels
of four-wheel drive tractors must be parallel to the lon-
gitudinal axis of the tractor, alternatively a slight toe-in
of the front wheels is permissible up to a maximum of
6 mm ( 0.24 in ) as measured at the edges of the wheel
rims.
To check the exact value of the toe-in setting of four-
wheel drive tractors, proceed as follows.
1. Inflate the front tires to the prescribed pressure.
2. Position the steering at the straight ahead position
(along the longitudinal axis of the tractor).
3. Check that the wheels are parallel to the longitudinal
axis of the tractor.
4. Make a chalk mark on the front inside edges of both
wheel rims, at the height of the wheel hub centers.
Measure the distance
(1) between the chalk marks.
5. Move the tractor forward to turn both front wheels
through 180 ° The chalk marks will now be measure
between the rear inside edges of the wheel rims at the
height of the wheel hub centers. Now measure the
distance
(2) checking that this new measurement is
equal to or greater than the distance (1) by a maximum
or 6 mm ( 0.24 in ).
The rotation of the wheels through 180 ° is necessary to
eliminate the effect of wear, misalignment or distortion
of the wheel rims on the measurements obtained.

6. If it is necessary to correct the wheel alignment, re-
move nut (1) and pull the tie rod end out of its housing.
Loosen the locknut (2) and screw the tie rod end (3) in
or out to increase or decrease the distance (2) .
Reposition the tie rod end in its housing and re-check
alignment.
After having adjusted the toe in to within the prescribed
limits, tighten locknut
(2) to a torque of 180 N·m ( 133 lb
ft ) and nut (1) to 100 N·m ( 74 lb ft ).
NOTE: The self-locking nut (1) , must be replaced each time
it is removed or partially unscrewed.
