Warning
Due to the considerable weight of
PAVT wheels, a crane must be used to
facilitate their removal and refitment.
The different track widths are obtained
by altering the position of the rim in rela-
tion to the disc, or by reversing the wheels
and transferring them from one side of the
tractor to the other.

Note
The heavy duty rear axle can be iden-
tified by the two lower link attachment
holes in the cast lugs under each axle
housing. Normal duty only have one hole.
Adjustment is as follows:
1. Select the required track settings (See
table 4-9).
2. Slightly slacken either the wheel to
axle, or the rim to disc nuts, or both
according to requirements.
3. Using a jack capable of lifting 5000 kg
(11000 lb) raise the rear wheels just
clear of the ground.
4. Remove the rim from the disc or the
complete wheel, or both and assem-
ble them with the rim and disc in their
new positions.
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.
