OPERATING
TEMPERATURE
A
CAUTION:
If
the
transmission
fluid
temperature
is
too
high,
stop
the
engine
immediately
and
check
the
transmission
fluid.
Norn1al
operating
temperature of
the
transmission
fluid
should
be
in
the
range of
122
0
F
(50
0
C)
to
212
0
F
(100
0
C)
..
A
maximum
temperature of
266
0
F (130
0
C)
may
b~
only
reached
for
a short
time.
Make
certain
there is enough space
around
the transmission
to
provide
good
ventilation and
cooling.
TRANSMISSION
COOLER
Coolers
are
standard equipment
for
the
ZF
10M,
ZF
12M,
ZF
15M,
ZF
15MA,
ZF
15MIV;
and
the
ZF
25M.
The cooler is a separate part of
the
transmission
which
prevents
any
possibilities of coolant
diluting
the
transmission
fluid.
However,
the continued
flow
of coolant thru the cooler
will,
in
time,
erode the inside of
the
cooler causing external
leaks.
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.
TRANSMISSION
COOLER
PERIODICAUY
INSPECT
FOR
EROSION
AND
LEAKAGE
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
checldng
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:
Drain
water
from
tlle
transmission
oil
cooler
and
replace
with
a proper
mixture
of antifreeze
coolant.
NOTE:
11zis
operation will nonnally occur
when
the
engine
raw
water cooling
syst~m
is
properly
winterized.
o
Clean
up
the
transmission
and
touch
up
unpainted
areas
(use
heat
resistant
paint).
Fill
the
transmission
with
De:>.1ron
III ATF
fluid
to
prevent internal
corrosion
(extended
storage
only,
twelve
months
or
more).
o
Loosen
attaching
hardware
from
the
transmission
output
flange
and
propeller shaft coupling
flange
before
removing
the boat
from
the
water.
Separate
the
flanges
and
spray
with
lubricant.
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 months or
more),
it should be topped offwith
fluid
to
prevent
inte172al
corrosion. Reduce
the
fluid level
before putting the engine back
into
service
