as to fully engage the locking mechanism. At
this time, there should be a clearance be-
tween the differential
lock
pedal and the
Tractor step-plate of 1/4 of an
inch.
If
this
adjustment is not correct,
proceed
as fol-
lows:
1. Loosen
the
clamp bolt securing the
pedal assembly to the differential lock shaft.
2. With the
differential
lock mechansim
fully engaged, position the pedal until there
is 1/4 of an inch clearance between the pedal
and the step plate.
3. Tighten clamp bolt
securely.

To
adjust
the brakes,
raise
both
rear
wheels off
the
ground. Remove
the adjusting
hole
covers.
With a suitable screwdriver,
tighten the
adjusting screws until
they
are
tight and
the wheels
cannot be
rotated.
Back
off the
adjusting
screws
until there
is no
longer a drag on the
drums.
Check drag
after each click.
NOTE:
If
the brakes
are malfunc-
tioning due
to
very damp climatic
conditions,
it
may be necessary
to
"burnish-in" the
linings
before ad-
justment.
With
the
rear wheels
raised,
run the
Tractor in
high
range-first
gear.
Lock one brake
and
partially apply
the
other brake
until the brake drum is too
hot to
touch.
Repeat the operation on the
opposite brake.
Allow drums to
cool,
then adjust.
Use extreme
care when carrying out this opera-
tion.
Check
the
master brake
setting
(both
brake pedals locked together).
Apply
the
master brake while driving the Tractor on
level ground. The Tractor
should
come to a
stop in a straight line.
If
Tractor pulls to
one side, the brake linkage requires ad-
justment.
Lengthen or shorten linkage so
Tractor stops
in a straight
line. (See Figs.
77
and 78.)
