TRANSMISSION
MAINTENANCE
Transmission maintenance is minimal.
Keep
the
exterior
housing clean, check the
fluid
level
as
part of your regular
routine,
and
change the
fluid
every 300 operating hours.
Periodically inspect the transmission
and
the
cooler for leaks
and corrosion. Make certain the air vent
is
clear
and
when
checking the
fluid
level look for signs of water contamination
(fluid will appear
as
strawberry cream).
Lay-up/Winterize
Storage requires special care. Follow these procedures:
0 Drain the water from the transmission oil cooler
and
replace it
with
a proper mixture of antifreeze coolant.
NOTE:
This
operation will usually occur
when
the
engine
raw
water cooling system is properly winterized.
0 Clean
up
the
transmission and touch-up unpainted areas
(use heat resistant paint).
0 Fill the transmission with Dextran III ATF
fluid
to
prevent internal corrosion. (Extended storage
only,
12
months or more).
0 Loosen attaching hardware froin the transmission
output
flange
and propeller shaft coupling
flange
before
removing the boat from the
water.
Separate the flanges
and spray
with
lubricant.
0 Inspect
the
gear shift cable, linkage,
and
attachments.
Look for corrosion of the end fittings, cracks or cuts
in
the conduit,
and
bending
of
the
actuator
rods.
Lubricate
all moving parts.
NOTE:
If
the
transmission is
to
be
stored for a long time
(twelve nwnths or
more),
it should
be
topped
off
with
fluid
to
prevent intemal corrosion. Reduce
the
fluid level
before putting
the
engine back
into
service.
OIL
COOLERS
The continued
flow
of raw water through
the
cooler will, in
time, erode the inside of the cooler causing cross leaks
to
occur.
These internal cooler leaks
will
cause one of the
following two problems:
1.
Transmission
fluid
will leak into the
flow
of
raw
water
and be discharged overboard through
the
engine exhaust.
A loss
of
transmission fluid will cause
the
transmission
to
fail.
2. The raw water
will
leak into the transmission
fluid
caus-
ing
an
increase
in
transmission
fluid.
This contaminated
fluid
will appear
as
strawberry cream.
The
transmission
will eventually
fail.
Either case requires
an
immediate response:
1.
Install a new oil cooler.
2. Refill the transmission with DEXTRON III
ATF.

BORG
WARNER
is
aware of the shock loads that
can
be
placed
on
its
gears
as
the
result of mechanical propeller
oper-
ation or fully reversing of
the
propeller blades
while
shifting.
Therefore torque loads
and
directional changes should
be
made
at
low
engine speeds. If it
is
found
that a failure
was
caused
by
a shock
load,
any
warranty claim
will
be
denied.
A
CAUTION:
System-related
noises
or
vibrations
can
occur
at
low
engine
speeds
which
can
cause
gear
rattle
resulting
in
damage
to
the
engine
and/or
transmission.
BORG
WARNER
is
not
responsible
for
total
system-
related
torsional
vibration
of
this
type.
If
any
problems occur
with
the transmission,
see
TRANSMISSION TROUBLESHOOTING in
this
manual.
If
water
has
contaminated the
fluid,
the
transmission
fluid
needs
to
be
cleaned out
and
replaced
with
fresh
fluid.
It
will
take
several
fluid
changes
to
get lid of
the
contamination.
Check your dipstick each time until
it appears
as
pure trans-
mission
fluid.
Change the transmission filter
and
clean out
the
fluid
lines that connect
to
the
cooler.
If
the
transmission fails
to
shift properly, it
will
most likely
need
the attention of a qualified transmission service
facility.
A transmission cooler
may
last ten years or more but,
in
some
circumstances, depending
on
operating
hours,
tropical
waters, maintenance,
etc.
it
might only last half that
time.
WESTERBEKE recommends having a spare cooler aboard.
