easily adjusted rear tread
width,
in
4-inch
gradL:a-
tions.
Rear
wheel
tread
widths
(52"
to
72")
are meas-
ured
from
center-to-center
of
tires
in
4-inch
incre-
ments.
To
adjust
PAVT rear
wheel
tread
width:
1. Remove
the
clamp
"stops",
from
each
master
rail by removing the studs
from
the
"stops".
Re-
position a
"stop"
on each
master
rail at
the
desired
tread
width
setting. (See Fig. 43.)
2. Loosen
the
ramp
clamp
nuts
about 3
turns
each. (See Fig. 43.)
3. Drive
the
Tractor
forward
or
rearward apply-
ing the brake opposite the rear
wheel
that
is being
adjusted,
until
the
ramp clamp contacts
the
stop on
each
master
rail.
4. Install
the
remaining ramp clamp stop on
one
master
rail and
tighten
the
ramp clamp
nuts
evenly to
220
ft
.-lbs. torque. (See Fig. 43.)
IMPORTANT:
To
insure
proper
wheel
align-
ment,
the
clamp
nuts
should
be
tightened
gradually
in
at
least
three
stages
(50,
100
and
220
ft.-lbs.)
using
a
criss-cross
pattern
until
they
are
fully
tightened.
5.
Following
the foregoing procedure, adjust
the
remaining
rear wheel.
NOTE:
On
extreme
rear
wheel
tread
width
sef1ing,
the
ends
of
the
rails
will
provide
the
limiting
stop.
CARE
OF
TIRES
To reduce
amount
of
wear, and prolong
life
of
tires,
it
is
important
correct pressures be
maintained
by regular checks.
When
Tractor is going
to
be
out
of
use
for
a
prolonged period,
or
is being stored, block up both
sides
of
axles to take
weight
of
Tractor
off
tires.
If oil, gasoline
or
similar
products are spilled
on a tire, clean
this
area
of
tire
immediately
. Never
park
or
stop Tractor
with
tires
standing in a
moist
oil patch.
Whenever
possible, park Tractor
where
tires
will
be shaded
from
direct rays
of
sun. This is par-
ticularly
important
if
Tractor is parked
for
prolonged
periods, or is being stored.
If
mounting
tubeless
tires
make sure flange and
bead area of
tire
and
rim
are free
of
dirt,
rust
or
old rubber. Rim
must
be smooth and clean and any
rusted areas
should be repainted
with
a
rust
inhib-
iting type paint.
TIRE PRESSURES
Tractor is shipped
with
tires
overinflated. Pres-
sures
must
be checked and adjusted before operating
in
field. SHOULD
BE
CHECKED WEEKLY. See Chart
for recommended
tire
pressure.
