Transmission Cooler; Maintenance - Westerbeke 65A-FOUR Operator's Manual

ZF MARINE TRANSMISSIONS
OPERATING TEMPERATURE
A
CAUTION:
If the fTansmission fluid temperature is
too high, stop the engine immediately and check the
transmission fluid.
Normal 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 (l30°
C)
may be 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-25M, ZF-25MA
and the ZF,30M,
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
thm
the cooler
will, in time, erode the inside of the cooler causing external
leaks.
A transmission cooler may last ten years or more
bu~
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
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 c()oler for leaks
and corrosion. Make certain the air vent is
cle~and
when
checking the fluid level look for signs of waterc(lnt8nnnation
(fluid will appear as strawberry cream).
Lay-up/Winlerize
Storage requires special care. Follow these proi;edures:
o
Drain water from the transmission oil coolerimd replace
with a proper mixture of antifreeze coolant.'.
NOTE:
This operation will normally occur 'When the
engine raw water cooling system
is
properly winterized.
o
cl~an up the transmission and touch up unpainted 'areas
(use heat resistant paint).
o
Fill the transmission with
Dextron III ATFfluid 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 hefore
removing the boat from the water. Separate the flanges
and spray with lubricant. .
o
Inspect the gear shift cable, linkage, and attachments.
Look for corrosion of the end fittings, cracks or cuts in
the
condui~
and bending of the actuator roqs:Lubricate
all moving parts.
NOTE:
If the trqnsmission is to be stored for.a long time
(twelve months or more), it slwuld be
topp~d
offwith
fluid
to
prevent intimal corrosion. Reduceth,e fluid. level
before putting the engine back into service
