HURTH HBWJZF TRANSMISSIONS
OPERATING TEMPERATURE.
A WARNING: If the transmiSsion fluid temperature
is· too high, stop the engine immediately and r:hlir:kthe
transmission fluid.
Normal openiting temperature of the transinission fluid
should be in the range of 122"F (50'C) to 212"F (IOO'C). A
maximum temperature of 266"F (130'C) may be only
·reached for a short time.
Make certain there is enough space around the transinission
to provide good ventilation and cooling.
TRANSMISSION_COOLER
Some WESTERBEKE model's transinissions are equipped
with an extemaIly attached convection type transmission
cooler.
The cooler is a separate patt of the transinission wltich
prevents any possibilities of coolant diluting the transinission
fluid. However, the continued flow of coolant thrn the cooler
will, in time, erode the inside of the cooler causing external
leaks.
A transinission cooler may last ten yemor more but, in
some circumst~ces, depending on operating hours, tropical
waters, maintenance, etc. it inight only last half that time.
WESTERBEKE recommends having a spare cooler aboard.
INSPECT FOR
lEAKAGE
MAINTENANCE
1bmsinission maintenance is ininimal. Keep the exterior
housing clean, check the fluid level as patt of your regular
routine, and change the fluid every 300 operating hours.
Periodicruly inspect the transinission and the cooler for leaks
and corrosion. Lubricate the cable connections. .
Lay-up/Winterize
Storage requires special care. Follow these procedures:
D Drain water from the transinission oil cooler and replace
with a proper mixture of antifreeze coolant.
NOTE: This operation will normally occur when the
engine raw water cooling system is properly winterized.
D Clean up the transmission and touch up unpainted areas
(use heat resistant paint).
D Fill the transmission with Dextran III ATF fluid to pre-
vent"intemal corrosion (extended storage only, twelve
months or more).
D Loosen attaclting hardware fiom the transmission output
flange and propeller shaft coupling flange before remov-
ing the boat from the water. Separate the flanges and .
spray with lubricant.
D Inspect the gear shift cable, linkage, and attachments.
Look for corrosion of the end fittings, cracks or cuts in
the conduit, and bendiug of the actuator rods. Lubricate
all moving parts.
NOTE: If the transmission is to be stored for a long time
ltwelve months or more), it should be topped offwith·
. fluid to prevent internal corrosion. Reduce the fluid level
before putting the engine back into service. (
