FRONT WHEEL TRACK ADJUST-
MENT (four wheel drive)
Front wheel drive tractors have fixed axle assem-
blies. However. the wheels are fully adjustable
having separate rims and center discs. The discs
are dished and by reversing their position on the
hub (by inter-changing the front wheels) two dif-
ferent track settings can
be
achieved. In addition,
the lugs
on
the wheel rim to which the discs are
attached are off-set relative
to
the center line
of
the wheel. By changing the wheel rim relative to
the center disc and/or the disc relative to the axle
hub a range
of
track settings may be achieved.
A WARNING:
With
a front wheel
on
a
.a
four
wheel
drive
tractor supported
on
a
stand.
never
attempt to rotate
the
wheel or start
the
engine.
This
may
cause
the
rear
wheels
to
move
resulting
in
the
tractor falling
from
the
stand.
Wheels
should always
be
supported
such
that
the
tires
are
only just clear
of
the
ground.
The sectioned drawings shown in the following
tables (Figures 37 - 39) illustrate the wheel
rim
and
disc positions relative to the hub at various
track settings.
Each drawing represents either a left-hand wheel
viewed
from the rear
or
a right-hand wheel
viewed from the front.
NOTE:
When
interchanging left and right-hand
wheel
assemblies,
ensure
the
tlV"
of
the
tire
tread
remains
pointing
in
the
direction
of
forward
travel.
