Maintenance and adjustment
83
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.
5. Oil the threads of the studs before fit-
ting the nuts.
6. On refitment, tighten the nuts progres-
sively to a torque of:
*
Disc to Axle Hub: 325 Nm (240 lbf ft)
*
Rim to Disc: 240 Nm (180 Ibf ft)
Caution
Recheck the wheel nut and rim bolt
torques after 10 hours (or 2 hours if
on loader work) and then check and if
necessary, retighten twice more at ten
hour intervals. This protects against the
loosening that occurs from assemblies
settling.
Four wheel drive track adjust-
ment
The different track widths are obtained
by altering the position of the rim in rela-
tion to the disc or by reversing the wheels.
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.
1. Select the required track setting .(See
figure 54 and table 4-12)
Fig. 54:
2. Slightly slacken either the wheel to
axle, or the rim to disc nuts, or both
according to the requirements.
3. Using a jack, raise the front wheels
just clear of the ground and support on
an axle stand.
4. Remove the rim from the disk, or the
complete wheel, or both and reassem-
ble them with the rim and disk in their
new position.
5. Oil the bolts or stud threads before fit-
ting the nuts, then tighten to a torque
of:
Disk to axle hub: 270 Nm (200 lbf ft)
Rim to disk: 190 Nm (140 lbf ft)
Caution
At the smaller track setting, a foul
condition may occur between the tyre
and tractor or loader, if fitted, when the
wheels are turned to the full lock posi-
tion. To avoid this condition you must
check by turning the wheels to full lock
and adjusting the steering stops as nec-
essary.
6. Set the steering stops (Fig. 54) to their
correct setting to prevent damage to
the tyres.
