MAINTENANCE/SERVICE
Traction Drive: Neutral Lock Adjustment (continued)
5. If machine "growls" severely
or
moves when
both ground speed lever and steering wheel are
in their neutral positions, shut off engine and
adjust as follows:
CAUTlON
:
Use
jack-stands
with
a
minimum
capacity
of
3 tons
(2720
kg)
to
provide
adequate
support
for ma-
chine.
a) Raise front
of
machine high enough
to
allow
both wheels
to
tum
freely and support with
jack-stands.
b) Determine, from the operator's position, which
drive wheel is moving and its direction
of
rotation. Do this with:
.,
Ground speed lever in neutral.
• Steering wheel locked.
• Speed range control in "Road" (Diesel only).
• Engine
at
full speed.
A
DANGER
: Never attempt to
adjust
with
engine
running.
Shut
off
engine
and
remove
key.
NOTE: The front pump drives the right wheel
mo
tor
and the rear pump drives the left wheel
motor. This means if the right wheel is out
of
neutral the front interlock bracket will require
adjustment.
If
the left wheel is moving, adjust-
ments are required
at
the rear interlock bracket.
Sometimes both sides will require adjustment.
d) Loosen the
two
nuts
at
ground speed lever
pivot
(K)
about three turns each.
e) Loosen
two
nuts
(L)
at the interlock bracket
(G)
which requires adjustment.
f)
Using nuts (M), adjust interlock bracket.
IMPORTANT:
If wheel was moving forward,
adjust bracket forward. If wheel was reversing,
adjust bracket rearward. Adjust nuts
(M)
in
1
/2
-
tum
increments only.
g) Tighten nuts (L), then nuts
(M)
.
h)
Repeat step b)
to
see if wheel is motionless.
If
not, repeat procedure.
i)
With the ground speed lever in neutral, tighten
the
two
nuts against the ground speed lever
pivot
(K)
.
NOTE:
For proper positioning
of
lever with
respect
to
serrated lock in side console, finger
tighten both nuts against the pivot, then
tighten nuts in 1 /2-turn increments, alternating
between the
two
nuts until both are tight.
j) Lower drive wheels
to
ground.
