DAILY
OPERATION
o Check the transmission fluid.
o Visually check the gear shift linkage and transmission.
o Start the engine
in
neutral. Allow a few minutes at idle
for the fluid to warm.
NOTE:
Too
Iowan
idle
speed will
produce
a
chattering
noise
from
the
transmission
gear and
damper
plate.
In
such
cases
the
idle
speed
should
be
increased.
o Shift into gear.
A
CAUTION:
Shifting
gears
above
1000
rpm
can
cause
damage
to
the
engine
damper
plate.
Pulling
the
throttle
back
to
Idle
when
shifting
gears
will
save
wear
on
the
transmission
and
the
damper
plate.
INSPECTION
o Visually check for oil leaks
at
the hydraulic connections.
Check for wear on the hydraulic lines and replace
if
worn.
o Lubricate the detent ball and shift cable attachments.
o Inspect the shift linkage.
o Inspect the transmission bolts; retorque
if
necessary.
A
CAUTION:
Clutch
fallurs will
occur
If
the
transmis-
sion
shift
lellSr
does
not
fully
engage
the
detent

CHANGING
THE
TRANSMISSION
FLUID
After the initial
50
hour change, the transmission fluid should
be
changed at every 300 operating hours thereafter or at win-
ter haul-out. However, the fluid
must
be changed whenever it
becomes contaminated, changes color,
or
smells rancid.
o Remove the oil filler cap and dipstick.
o Remove the oil cooler return line and allow the oil to
drain into a container.
o Reconnect the oil cooler return line.
D Use a suction pump to remove the transmission oil
through the filler cap/dipstick hole.
o Clean off the transmission and properly dispose
of
the
used fluid.
o Refill the transmission with
DEXTRON
/II
ATF. The
quantity will vary depending on the transmission model
and the installation angle. Fill through the dipstick hole.
D Check the dipstick for the proper fluid level.
D Replace the oil filler
cap
and dipstick. (Press the dipstick
into place and tum clockwise until finger-tight.)
D Run the engine, shutdown and recheck the fluid level.
A
WARNING:
Never
pull
out
the
dipstick
while
the
engine
Is
running.
Hot
nuld will
splash
from
the
dipstick
hole.
This
could
cause
severs
bums.
Oil
Capacity
Approximately 2.5 quarts (2.36 liters)
will
fill
most transmis-
sions to the oil level fill
mark
on the dipstick. Many variables
have a direct relationship to the oil capacity. Additional oil
will
be required to fill the oil cooler and the cooler lines. The
angle
of
installation will make a difference
in
the quantity
of
oil required to fill the transmission. .
Oil
Temperature
Make
certain
the
rubber
____
seal
Is
screwed
tight
to
the
handle.
OILDIPsnCK
A maximum oil temperature
of
190
0
P (88°C) is recom-
mended. Discontinue operation anytime sump oil tempera-
ture exceeds 230
0
P (1lO
D
C).
PRESSURE
GAUGE
An
optional mechanical pressure gauge can be installed
at
the control panel to constantly monitor the pressure
of
the
transmission fluid. A normal reading at
2000 rpm
in
forward
gear should indicate 95 -
120 Ib-in
2
(6.7 - 8.4 kg-cm
2
)
and be
constant.
