Table 2:
1. Raise the front wheels clear of the
ground.
2. Remove the bolts (1) and nuts each side.
3. Remove the tie rod bolts (2) each side.
4. Slide the axle arms and the tie rods to
the required track setting as in Table 2.
5. Refit the bolts and nuts (1) through the
appropriate axle beam holes, ensur-
ing that the bolt heads are correctly
located in the triangular holes in the
axle beam, and tighten to a torque of
220 Nm (160 lbf ft).
6. Refit the bolts and lock-nuts (1), and
tighten to a torque of 33 Nm (24 lbf ft).
7. Check the front wheel alignment - see
page 81.
FRONT TRACK ADJUSTMENT (Fig.
50)
(Four —wheel drive)
Removing wheels for reversal.
On tractors that have welded rims and
discs there are only two track settings ob-
tainable. These are obtained by removing
the wheels and fitting them on the oppo-
site side of the tractor.
They come in two sizes and provide
an easily adjusted track width (1123 mm
in original condition and 1624 mm if the
wheels reversed) . To adjust the track pro-
ceed as follows:
1. Using a jack capable of lifting 1500
kg (3300lb) raise the rear wheels just
clear of the ground and support on a
pair of axle stands.
2. Supporting the wheel with the crane,
remove the wheel nuts and the wheel.
If possible, lean the wheel against a
wall to ease handling on refitment.
3. Transfer the wheel to the other side
of the tractor and refit the wheel nuts.
4. Refit the other wheel in a similar man-
ner.
5. Oil the bolts or stud threads before fit-
ting the nuts, then tighten the disk to
axle hub by 270 Nm (200 lbf ft).
6. Remove the axle stands.
7. Recheck the torques after 10 hours (or
2 hours if on loader work) and then
check and if necessary, retighten twice
more at ten hourly intervals. This pro-
tects against the loosening that occurs
from these assemblies settling down.
NOTE
If the wheels are reversed, they must
be transferred to the opposite side of
the tractor so as to maintain the correct
tyre tread direction.
